The problem was noted several decades ago but its causes are unknown. The aim of this work is to investigate the association between the occurrence of the decline and site characteristics considered to be relevant from the ecological point of view. A multivariate analysis is carried out using topographic and climatic information, obtained from 32 sites, within the limits of the Nahuel Huapi National Park, showing a wide range of decline and mortality incidence. Results of this study suggest that an ecological pattern of tree decline and mortality exists. The &lt;em&gt;A. chilensis&lt;/em&gt; forests seem more prone to developing symptoms when occurring at sites with higher precipitation and not very high altitudes. To the eastern limit of its distribution, where precipitation is substantially low, &lt;em&gt;A. chilensis&lt;/em&gt; forests show no symptoms of decline. It is, thus, hypothesized that sites with relatively poor soil drainage are more prone to develop symptoms. However, it is not clear whether high soil moisture directly affects roots or it produces a more suitable environment for root pathogen proliferation and infection.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Bakonyi, J.</style></author><author><style face="normal" font="default" size="100%">Nagy, Z.

Primer pairs were derived from randomly amplified polymorphic DNA (RAPD) fragments that were unique to various subspecies of this alder pathogen. The primer pair set, SAP1/SAP2 (SAP), was derived from a 0.93-kb RAPD fragment amplified from &lt;em&gt;P. alni&lt;/em&gt; ssp. &lt;em&gt;alni&lt;/em&gt;. The primer pair set, SWAP1/SWAP2 (SWAP), was derived from a 1.13-kb fragment amplified from &lt;em&gt;P. alni&lt;/em&gt; ssp. &lt;em&gt;uniformis&lt;/em&gt;. Patterns of SAP and SWAP amplification enabled distinction among the three subspecies. No PCR products were amplified from isolates of 31 other &lt;em&gt;Phytophthora&lt;/em&gt; spp. examined, including &lt;em&gt;P. cambivora&lt;/em&gt; and &lt;em&gt;P. fragariae&lt;/em&gt;, the suspected progenitors of &lt;em&gt;P. alni&lt;/em&gt;. The SAP and SWAP primer sets were able to detect a minimum of 10&amp;nbsp;pg of DNA from pure cultures or DNA extracted from as few as 10 zoospores. Pathogen DNA could also be amplified directly from bark lesions of artificially inoculated and naturally infected common alders and from lesions developed on common cherry-laurel leaves used in baiting the pathogen from infested soil. Direct detection of pathogen DNA from alder tissue using SAP and SWAP primer sets should prove useful in developing measures for effective quarantine and management of &lt;em&gt;P. alni&lt;/em&gt;.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Balci, Y.</style></author><author><style face="normal" font="default" size="100%">Balci, S.</style></author><author><style face="normal" font="default" size="100%">Eggers, J.</style></author><author><style face="normal" font="default" size="100%">MacDonald, W.

Surveys demonstrated the presence of four species of &lt;em&gt;Phytophthora&lt;/em&gt; including one novel species. By far, the most common species was &lt;em&gt;P.&amp;nbsp;cinnamomi&lt;/em&gt;; &lt;em&gt;P.&amp;nbsp;citricola&lt;/em&gt; and &lt;em&gt;P.&amp;nbsp;cambivora&lt;/em&gt; were isolated infrequently. In few instances, &lt;em&gt;P.&amp;nbsp;cinnamomi&lt;/em&gt; was isolated from fine roots and necroses on larger roots. No special pattern of incidence was found, but &lt;em&gt;P.&amp;nbsp;cinnamomi&lt;/em&gt; was more commonly isolated from greater Integrated Moisture Index values suggesting moist lower bottomlands favour this &lt;em&gt;Phytophthora&lt;/em&gt; species. When tree crown condition was examined relative to the presence of &lt;em&gt;Phytophthora&lt;/em&gt;, no significant association was found. However, roots of declining &lt;em&gt;P.&amp;nbsp;cinnamomi&lt;/em&gt;-infested trees had 2.5 times less fine roots than non-infested and healthy trees, which was significantly different. The population densities of &lt;em&gt;P.&amp;nbsp;cinnamomi&lt;/em&gt; from declining trees were significantly greater than from healthy trees, suggesting increased pathogen activity that has the potential to cause dieback and decline and possibly the cause of a reduced fine root amount found on declining trees.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Yilmaz Balci</style></author><author><style face="normal" font="default" size="100%">Balci, Selin</style></author><author><style face="normal" font="default" size="100%">Jaime E.

Expected heterozygosity and other indices suggested a lower level of diversity among &lt;em&gt;P. cinnamomi&lt;/em&gt; than &lt;em&gt;P. plurivora&lt;/em&gt;.

In contrast, P. plurivora isolates separated into six clusters, one of which included approximately 40% of the isolates. &lt;em&gt;P. plurivora&lt;/em&gt; isolates recovered from the environment (e.g. soil, water) were genotypically more diverse than those found causing lesions. For both species, isolate origin (forest vs. nursery or among nurseries) was a significant factor of heterozygosity. Clonal groups existed within &lt;em&gt;P. cinnamomi&lt;/em&gt; and &lt;em&gt;P. plurivora&lt;/em&gt; and included isolates from both forest and nurseries, suggesting that a pathway from nurseries to forests or visa verse exists.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>10</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Beever, JE</style></author><author><style face="normal" font="default" size="100%">Coffey, MD</style></author><author><style face="normal" font="default" size="100%">Ramsfield, TD</style></author><author><style face="normal" font="default" size="100%">Dick, MA</style></author><author><style face="normal" font="default" size="100%">Horner, IJ</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Kauri (Agathis australis) Under Threat From Phytophthora?</style></title><secondary-title><style face="normal" font="default" size="100%">Fourth Meeting of IUFRO Working Party S07.02.09</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2007</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2009</style></date></pub-dates></dates><publisher><style face="normal" font="default" size="100%">U.S. Department of Agriculture, Forest Service Pacific Southwest Research Station</style></publisher><pub-location><style face="normal" font="default" size="100%">Monterey, California</style></pub-location><volume><style face="normal" font="default" size="100%">General Technical report PSW-GTR-221</style></volume><pages><style face="normal" font="default" size="100%">74–85</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;div class=&quot;page&quot; title=&quot;Page 86&quot;&gt;&lt;div class=&quot;layoutArea&quot;&gt;&lt;div class=&quot;column&quot;&gt;&lt;p&gt;&lt;span style=&quot;font-size: 10.000000pt; font-family: 'TimesNewRomanPSMT';&quot;&gt;Five species of &lt;/span&gt;&lt;span style=&quot;font-size: 10.000000pt; font-family: 'TimesNewRomanPS'; font-style: italic;&quot;&gt;Phytophthora &lt;/span&gt;&lt;span style=&quot;font-size: 10.000000pt; font-family: 'TimesNewRomanPSMT';&quot;&gt;have been recorded from &lt;/span&gt;&lt;span style=&quot;font-size: 10.000000pt; font-family: 'TimesNewRomanPS'; font-style: italic;&quot;&gt;Agathis australis &lt;/span&gt;&lt;span style=&quot;font-size: 10.000000pt; font-family: 'TimesNewRomanPSMT';&quot;&gt;(kauri) or soil in kauri forests: &lt;/span&gt;&lt;span style=&quot;font-size: 10.000000pt; font-family: 'TimesNewRomanPS'; font-style: italic;&quot;&gt;P. cinnamomi&lt;/span&gt;&lt;span style=&quot;font-size: 10.000000pt; font-family: 'TimesNewRomanPSMT';&quot;&gt;, &lt;/span&gt;&lt;span style=&quot;font-size: 10.000000pt; font-family: 'TimesNewRomanPS'; font-style: italic;&quot;&gt;P. cryptogea&lt;/span&gt;&lt;span style=&quot;font-size: 10.000000pt; font-family: 'TimesNewRomanPSMT';&quot;&gt;, &lt;/span&gt;&lt;span style=&quot;font-size: 10.000000pt; font-family: 'TimesNewRomanPS'; font-style: italic;&quot;&gt;P. kernoviae&lt;/span&gt;&lt;span style=&quot;font-size: 10.000000pt; font-family: 'TimesNewRomanPSMT';&quot;&gt;, &lt;/span&gt;&lt;span style=&quot;font-size: 10.000000pt; font-family: 'TimesNewRomanPS'; font-style: italic;&quot;&gt;P. nicotianae &lt;/span&gt;&lt;span style=&quot;font-size: 10.000000pt; font-family: 'TimesNewRomanPSMT';&quot;&gt;and &lt;/span&gt;&lt;span style=&quot;font-size: 10.000000pt; font-family: 'TimesNewRomanPS'; font-style: italic;&quot;&gt;Phytophthora &lt;/span&gt;&lt;span style=&quot;font-size: 10.000000pt; font-family: 'TimesNewRomanPSMT';&quot;&gt;taxon Agathis (PTA) initially recorded as &lt;/span&gt;&lt;span style=&quot;font-size: 10.000000pt; font-family: 'TimesNewRomanPS'; font-style: italic;&quot;&gt;P. heveae&lt;/span&gt;&lt;span style=&quot;font-size: 10.000000pt; font-family: 'TimesNewRomanPSMT';&quot;&gt;. &lt;/span&gt;&lt;span style=&quot;font-size: 10.000000pt; font-family: 'TimesNewRomanPS'; font-style: italic;&quot;&gt;P. cinnamomi &lt;/span&gt;&lt;span style=&quot;font-size: 10.000000pt; font-family: 'TimesNewRomanPSMT';&quot;&gt;has been found widely in natural stands and has been linked with ill-thrift and occasional tree death, especially in regenerating stands on poorly drained sites. PTA, which is known from fewer natural stands, is associated with a collar rot, causing large bleeding lesions near the ground, yellowing foliage, and tree death. The other three species have only been reported once. ITS sequence studies of PTA show it belongs with, but is distinct from, &lt;/span&gt;&lt;span style=&quot;font-size: 10.000000pt; font-family: 'TimesNewRomanPS'; font-style: italic;&quot;&gt;P. heveae &lt;/span&gt;&lt;span style=&quot;font-size: 10.000000pt; font-family: 'TimesNewRomanPSMT';&quot;&gt;in ITS clade 5.

It is proposed that PTA may be introduced to New Zealand, but too few isolates are available to determine whether genetic variability of this species provides support for this hypothesis. Recent surveys have found collar rot is widely distributed across the natural range of kauri. Typically, affected stands are relatively small in size. Size class distributions indicate trees of many ages are affected and a disease front can sometimes be detected. Pathogenicity tests show PTA is highly pathogenic to kauri. We propose that collar rot caused by PTA is an emerging disease caused by an introduced pathogen that is spreading slowly from widespread disease foci. It poses a threat to kauri, both at the individual icon level and at the population level, with flow-on effects to kauri ecosystems. &lt;/span&gt;&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Belisario, A.</style></author><author><style face="normal" font="default" size="100%">Maccaroni, M.</style></author><author><style face="normal" font="default" size="100%">Vettorazzo, M.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">First report of Phytophthora cambivora causing bleeding cankers and dieback on beech (Fagus sylvatica) in Italy</style></title><secondary-title><style face="normal" font="default" size="100%">Plant Disease</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2006</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://apsjournals.apsnet.org/doi/abs/10.1094/PD-90-1362C</style></url></web-urls></urls><number><style face="normal" font="default" size="100%">10</style></number><volume><style face="normal" font="default" size="100%">90</style></volume><pages><style face="normal" font="default" size="100%">1362-1362</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;European beech (&lt;em&gt;Fagus sylvatica&lt;/em&gt;) is an important forest tree species common in northern and central Europe. In Italy, this species is typical in mountain areas over 1,000 m above sea level. In the last decade, decline and death was reported on European beech caused by several &lt;em&gt;Phytophthora&lt;/em&gt; species (2), and &lt;em&gt;P. pseudosyringae&lt;/em&gt; was recently reported in Italy (3). During 2004 and 2005, seven declining and dying &lt;em&gt;F. sylvatica&lt;/em&gt; trees, older than 20 years, were observed in the Veneto Region of Italy with symptoms of bleeding cankers at the base of trunks and on branches. Cankers on the collar showed tongue-shaped necroses of the inner bark and cambium tissues. Four trees were in a public park of Mestre and three were in a forest stand in the province of Belluno. Samples were taken from declining trees, one in the park and two in the forest. Inner bark and cambium tissue pieces were cut from the canker margins, cultured on CARPBHy-agar (corn meal agar amended with 250 μg ml-1 ampicillin, 10 μg ml-1 rifampicin, 10 μg ml-1 pimaricin, 15 μg ml-1 benomyl, 50 μg ml-1 hymexazol), and incubated at 20°C. Ten morphologically similar isolates were subcultured as single hyphal tips and characterized. These isolates produced nonpapillate sporangia that were ovoid, obpyriform or ellipsoid, and exhibited predominately internal proliferation in soil extract. Hyphal swellings with outgrowths were present under those conditions. The morphological characteristics were consistent with those of &lt;em&gt;P. cambivora&lt;/em&gt; (1). Base sequences of the ITS region of rDNA were determined for six of the isolates, and an 832-bp fragment was amplified for each isolate and that sequence was 100% homologous with sequences DQ396418 and AY880985 of &lt;em&gt;P. cambivora&lt;/em&gt; in the NCBI database (http://www.ncbi.nlm.nih.gov/BLAST/). The sequence of one isolate, ISPaVe 1950, was deposited in GenBank (Accession No. AM269752). Pathogenicity tests were conducted with 2-year-old potted beech seedlings. Inoculum of representative isolates was grown for 4 weeks on sterilized millet seeds moistened with V8 broth and added to soil at 3% (wt/vol). Control plants received sterilized inoculum only. The soil was flooded for 48 h. Inoculations were performed during May 2005 at 15 to 35°C with six replicates for the inoculated and control plants. The plants were maintained outdoors and assessed after 3 months. Wilt, root rot, and dark brown lesions at the collar developed on inoculated plants, but not on the controls. Symptoms were similar to those on naturally infected trees. The pathogen reisolated from the inoculated plants was morphologically identical to the original isolates, which confirmed &lt;em&gt;P. cambivora&lt;/em&gt; as the causal agent. To our knowledge, this is the first report of &lt;em&gt;P. cambivora&lt;/em&gt; on beech in Italy.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Belisario, A.</style></author><author><style face="normal" font="default" size="100%">Luongo, L.</style></author><author><style face="normal" font="default" size="100%">Vitale, S.</style></author><author><style face="normal" font="default" size="100%">Galli, M.</style></author><author><style face="normal" font="default" size="100%">Haegi, A.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Phytophthora gonapodyides Causes Decline and Death of English (Persian) Walnut ( Juglans regia) in Italy</style></title><secondary-title><style face="normal" font="default" size="100%">Plant Disease</style></secondary-title><short-title><style face="normal" font="default" size="100%">Plant Disease</style></short-title></titles><dates><year><style  face="normal" font="default" size="100%">2016</style></year><pub-dates><date><style  face="normal" font="default" size="100%">Jan-12-2016</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://apsjournals.apsnet.org/doi/10.1094/PDIS-03-16-0394-PDN</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">100</style></volume><pages><style face="normal" font="default" size="100%">2537 - 2537</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;In late spring 2015, several commercially grown Persian walnut (&lt;em&gt;Juglans regia&lt;/em&gt; L.) cv. Lara trees in northeastern Italy (Udine) exhibited extensive foliar wilt and canopy decline associated with collar and root rot. Sudden collapse was recorded in about 80% of trees facing an irrigation canal. Symptomatic tissues excised from roots and collars of affected plants were surface disinfested for 1 min in a 1% NaOCl solution, rinsed for 5 min in sterile distilled water, and placed onto P&lt;sub&gt;5&lt;/sub&gt;ARPH selective medium. A &lt;em&gt;Phytophthora&lt;/em&gt;-like organism was consistently isolated. Pure cultures, with a typical rosette pattern, were obtained by single-hyphal transfers onto potato dextrose agar (PDA). Mycelial disks of three isolates, AB260, AB261, and AB262, grown on carrot piece agar, were floated in petri plates with soil extract solution and incubated under continuous fluorescent light at room temperature. Within 48 to 72 h, sporangia were produced that were persistent, nonpapillate, tapered at the apex, and 40.0 to 102.8 × 22.8 to 45.7 µm (average 56 × 33 µm of 30 sporangia). Both internal and external proliferations were observed. Oospores and chlamydospores were absent. These morphological characteristics all corresponded to those reported for &lt;em&gt;Phytophthora gonapodyides&lt;/em&gt; (&lt;a id=&quot;b1&quot; class=&quot;ref bibr&quot;&gt;&lt;/a&gt;Brasier et al. 1993; &lt;a id=&quot;b3&quot; class=&quot;ref bibr&quot;&gt;&lt;/a&gt;Erwin and Ribeiro 1996). Optimal growth for all three isolates was at 30°C (3.4 mm/day), with limited growth at 4°C (1.25 mm/day), and no growth at 35°C. The identity was confirmed by sequencing the internal transcribed spacer (ITS) using universal primers ITS4 and ITS6 (&lt;a id=&quot;b2&quot; class=&quot;ref bibr&quot;&gt;&lt;/a&gt;Cooke et al. 2000) and cytochrome c oxidase, subunit II (&lt;em&gt;Cox&lt;/em&gt; II) (&lt;a id=&quot;b5&quot; class=&quot;ref bibr&quot;&gt;&lt;/a&gt;Martin and Tooley 2003). BLAST analysis of ITS 821-bp segment (GenBank accession nos. LN877760, LN901312, LN901313) showed 100% identity with published &lt;em&gt;P. gonapodyides&lt;/em&gt; sequences available in GenBank (i.e., HQ261570, AF541889, or AF541888), as well as with a &lt;em&gt;Cox&lt;/em&gt; II 568-bp segment (LN877762, LN894191, LN894192) against AY129197. Greenhouse pathogenicity tests were conducted in controlled conditions. A total of six 1-year-old shoots cut from &lt;em&gt;J. regia&lt;/em&gt; plants, about 2 cm in diameter, were used and three inoculation points each were made. Mycelial plugs (6 mm in diameter) cut from margins of actively growing 10-day-old cultures on PDA were inserted through the epidermis into phloem tissue. Controls were treated as described above except that sterile PDA plugs replaced the inoculum. Shoots were incubated in test tubes with sterile water in the dark at 24 ± 2°C. After 2 weeks, lesions were evident at all inoculation points, with an average length of 26 mm. Symptoms were similar to those caused by natural infection. &lt;em&gt;P. gonapodyides&lt;/em&gt; was consistently reisolated from lesion margins. No colonies were isolated from control plants that remained symptomless. &lt;em&gt;P. gonapodyides&lt;/em&gt; is ubiquitous in streams and ephemeral water pools, and is capable of saprophytic existence (&lt;a id=&quot;b3&quot; class=&quot;ref bibr&quot;&gt;&lt;/a&gt;Erwin and Ribeiro 1996). Although it is mainly known as a minor pathogen, there are reports indicating that some isolates can be highly virulent (&lt;a id=&quot;b6&quot; class=&quot;ref bibr&quot;&gt;&lt;/a&gt;Orlikowski et al. 2011) as in the present study where well developed 7-year-old walnut trees were killed by the pathogen. In the current study, &lt;em&gt;P. gonapodyides&lt;/em&gt; aggressiveness was most likely sustained by the prolonged presence of flooding water at the root level, and a cool soil environment. To our knowledge, this is the first report of &lt;em&gt;P. gonapodyides&lt;/em&gt; on Persian walnut in Italy or elsewhere.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">12</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Bellgard, S.

This study developed techniques to visualize early infection of kauri by PTA in deliberately inoculated seedlings. Conventional light microscopy was carried out on cleared and stained roots using trypan blue to observe PTA structures. Additionally, scanning electron microscopy (SEM) was used to study the PTA root structures at a higher resolution. A fluorescent &lt;em&gt;in&amp;nbsp;situ&lt;/em&gt; hybridization assay (FISH) was developed using a PTA-specific probe to label PTA structures &lt;em&gt;in planta&lt;/em&gt;. Infection progression in roots of 2-year-old kauri inoculated with PTA at 5, 10, 16 and 20&amp;nbsp;days post-inoculation (d.p.i.) was compared using these three approaches. Light microscopy identified no &lt;em&gt;Phytophthora-&lt;/em&gt;like structures in the control treatments. In PTA-inoculated plants, lignitubers were produced 5&amp;nbsp;d.p.i. in cortical cells. Infection was localized after 5&amp;nbsp;days, but as the infection progressed (up to 20&amp;nbsp;d.p.i.), the ‘degree’ of root infection increased, as did the number of replicates in which structures were observed. SEM provided higher resolution images; again, no PTA structures were observed in the negative control material examined. The slide-based FISH-specificity assay successfully hybridized with PTA hyphae. Fluorescence was observed using 330–380&amp;nbsp;nm excitation and an emission filter at 420&amp;nbsp;nm (DAPI), with PTA nuclei fluorescing a bright greenish-yellow. Cross-reactivity was not observed when the assay was applied to six other non-target &lt;em&gt;Phytophthora&lt;/em&gt; species. Successful hybridization reactions occurred between the primer and PTA structures &lt;em&gt;in planta&lt;/em&gt;. Applying this FISH assay has allowed clear differentiation of the intracellular and intercellular structures of PTA. The technique can be applied to longer term studies or analysis of &lt;em&gt;ex situ&lt;/em&gt; inoculation studies aiming to elucidate differential host-responses to the pathogen. Additionally, the technique could be applied to study the interactions with other fungal endophytes (e.g. mycorrhizal fungi), which could be assessed for biocontrol potential as part of the integrated management of the disease.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Benson, D.

In total, 231 Phytophthora strains were isolated using baiting assays and identified based on morphological characteristics and sequences of nuclear and mitochondrial loci. Twenty-one Phytophthora spp. in nine clades and one unidentified species were present. Phytophthora abietivora, a recently described clade 7a species, was recovered from diseased tissue of 10 native broadleaved plants and twice from soil from 12 locations. Phytophthora abietivora is most likely endemic to PA based on pathogenicity tests on six native plant species, intraspecific genetic diversity, wide distribution, and recoveries from Abies Mill. and Tsuga Carrière plantations dating back to 1989. Cardinal temperatures and morphological traits are provided for this species. Other taxa, in decreasing order of frequency, include P. chlamydospora, P. plurivora, P. pini, P. cinnamomi, P. xcambivora, P. irrigata, P. gonapodyides, P. cactorum, P. pseudosyringae, P. hydropathica, P. stricta, P. xstagnum, P. caryae, P. intercalaris, Phytophthora ‘bitahaiensis’, P. heveae, P. citrophthora, P. macilentosa, P. cryptogea, and P. riparia. Twelve species were associated with diseased plant tissues. This survey documented 53 new plant-Phytophthora associations and expanded the known distribution of some species.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Elizabeth Blackwell</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">The life history of Phytophthora cactorum (Leb. &amp; Cohn) Schroet</style></title><secondary-title><style face="normal" font="default" size="100%">Transactions of the British Mycological Society</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">1943</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.sciencedirect.com/science/article/B985G-4YW2HHM-D/2/d8cd209743ea7bb728b94dadd761bd5d</style></url></web-urls></urls><number><style face="normal" font="default" size="100%">1-2</style></number><volume><style face="normal" font="default" size="100%">26</style></volume><pages><style face="normal" font="default" size="100%">71 - 89</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Summary An account is given of the life history of Phytophthora Cactorum (Leb. &amp; Cohn) Schroet., a paragynous, homothallic species.

Their morphology and isozyme patterns for MDH and GPI were compared with those of seven known &lt;em&gt;Phytophthora&lt;/em&gt; species. Isolates from Indonesia assigned to &lt;em&gt;P. arecae&lt;/em&gt; or &lt;em&gt;P. palmivora&lt;/em&gt; by morphology had identical isozyme patterns and could not be separated by cluster analysis. Isolates of &lt;em&gt;P. palmivora&lt;/em&gt; had one single-banded, and three triple-banded GPI patterns, one of which was unique to isolates from coconut. Isolates from Ivory Coast were assigned by morphology and by a distinctive MDH isozyme pattern to &lt;em&gt;P. katsurae&lt;/em&gt;. They showed some morphological similarities, and had an identical GPI isozyme pattern to reference cultures of &lt;em&gt;P. heveae&lt;/em&gt;, previously reported as a pathogen on coconut. We conclude that &lt;em&gt;P. palmivora&lt;/em&gt; is the main pathogen associated with bud rot and premature nut-fall in Indonesia, whereas &lt;em&gt;P. katsurae&lt;/em&gt; is associated with premature nut-fall in Ivory Coast.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Jaime E.

(manzanita), &lt;em&gt;Camellia&lt;/em&gt; spp., &lt;em&gt;Laurus nobilis&lt;/em&gt; (bay), &lt;em&gt;Buxus sempervirens&lt;/em&gt; (boxwood), &lt;em&gt;Rhododendron&lt;/em&gt; sp., &lt;em&gt;Arbutus unedo&lt;/em&gt; (strawberry tree), and &lt;em&gt;Sequoia sempervirens&lt;/em&gt; (coast redwood). Isolates were collected from Shasta, Contra Costa, San Diego, Solano, Santa Cruz, Alameda, Sacramento, San Joaquin, Monterey, and Los Angeles Counties. Isolates from &lt;em&gt;A. unedo&lt;/em&gt; tissue on PARP medium produced apapillate, obovate sporangia 25 to 80 × 15 to 40 μm (48.0 × 26.9 μm average) and a few isolates produced intercalary and terminal chlamydospores at 22°C (30 to 46 μm diameter, 38.9 μm average). The internal transcribed spacer region (ITS) of rDNA was amplified from four isolates using ITS1 and ITS4 primers as described by White et al. (3) and the amplicons sequenced (GenBank Accession Nos. JQ307188 through JQ307191). BLAST analysis of the amplicons showed 99 to 100% identity with the ITS sequence of &lt;em&gt;Phytophthora&lt;/em&gt; taxon Pgchlamydo from forest streams in Oregon (GenBank Accession No. HM004224) (1). Pathogenicity tests were performed on &lt;em&gt;B. sempervirens, C. sasanqua, L. nobilis&lt;/em&gt;, and &lt;em&gt;A. unedo&lt;/em&gt;. Five plants of each species were inoculated with 6-mm plugs taken from the margin of a 7- to 10-day-old culture grown on V8 juice agar. Plant leaves were wounded with a sterile pushpin and two agar plugs were covered with a freezer tube cap filled with sterile dH&lt;sub&gt;2&lt;/sub&gt;O and clipped to the underside of the leaves with a sterile pin-curl clip (4). Inoculated plants were sprayed with water, covered with plastic bags, and incubated for 2 days, when bags and plugs were removed. Five leaves of each isolate plus five control plugs using V8 juice agar alone were inoculated on each plant. Plants were incubated for 12 days at 18°C (16-h photoperiod). Lesions formed on all inoculated plants, ranging in size from approx. 1 mm on &lt;em&gt;B. sempervirens&lt;/em&gt; to 9.2 × 10.9 mm average on &lt;em&gt;A. unedo&lt;/em&gt;. The lesions on &lt;em&gt;A. unedo&lt;/em&gt; grew into and caused the mid-vein to blacken. The lesion sizes on camellia and bay were larger than those formed on &lt;em&gt;B. sempervirens&lt;/em&gt; and smaller than those formed on &lt;em&gt;A. unedo&lt;/em&gt;, with most lesions surrounded by a dark ring. &lt;em&gt;Phytophthora&lt;/em&gt; taxon Pgchlamydo is associated with leaf lesions on rhododendron and dieback of yew in Minnesota (2). To our knowledge, this is the first report of &lt;em&gt;Phytophthora&lt;/em&gt; taxon Pgchlamydo causing disease in camellia, bay, strawberry tree, and boxwood in California. &lt;em&gt;Phytophthora&lt;/em&gt; taxon Pgchlamydo causes damage that is indistinguishable from the quarantine pest, &lt;em&gt;P. ramorum&lt;/em&gt; (4).&lt;/p&gt;&lt;p class=&quot;last&quot;&gt;&lt;em&gt;References&lt;/em&gt;: (1) P.

Samples were prescreened by an enzyme-linked immunosorbent assay (ELISA) that detects &lt;em&gt;Phytophthora&lt;/em&gt; spp. and tested by culture, &lt;em&gt;P. ramorum&lt;/em&gt;-specific real-time polymerase chain reaction (PCR), and nested PCR. Yearly percentages of infected samples ranged from 0.6 to 2.3%. &lt;em&gt;Camellia&lt;/em&gt; spp., &lt;em&gt;Rhododendro&lt;/em&gt;n spp., &lt;em&gt;Magnolia&lt;/em&gt; spp., &lt;em&gt;Pieris&lt;/em&gt; spp., and &lt;em&gt;Laurus nobilis&lt;/em&gt; tested positive the most frequently in the nurseries and &lt;em&gt;Lithocarpus densiflorus&lt;/em&gt;, &lt;em&gt;Umbellularia californica&lt;/em&gt;, and &lt;em&gt;Quercus agrifolia&lt;/em&gt; tested positive most often from wild lands. Of the 118,410 samples isolated onto PARP media, 0.8% was identified as &lt;em&gt;P. ramorum&lt;/em&gt;. Of 115,056 samples tested by ELISA, 5.9% tested positive for &lt;em&gt;Phytophthora&lt;/em&gt; spp. Of the 6,520 samples tested by PCR, 12.4% tested positive for &lt;em&gt;P. ramorum&lt;/em&gt;. The false-negative, positive, and internal control failure rates of the assays are discussed. After removing the seasonal effect of sampling strategy, isolation of the pathogen into culture was found to be seasonally dependent whereas detectability by PCR and ELISA was not. To our knowledge, this is the first evaluation of a regulatory testing program for a plant pathogen on this scale using standardized assays.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Bowers, J.

The noted incidence of kauri dieback has increased in the past decade, and even trees &amp;gt;1000&amp;nbsp;years old are not immune. This disease has profound effects on both forest ecosystems and human society, particularly indigenous Māori, for whom kauri is a &lt;em&gt;taonga&lt;/em&gt; or treasure of immense significance. This review brings together existing scientific knowledge about the pathogen and the devastating disease it causes, as well as highlighting important knowledge gaps and potential approaches for disease management. The life cycle of &lt;em&gt;P.&amp;nbsp;agathidicida&lt;/em&gt; is similar to those of other soilborne &lt;em&gt;Phytophthora&lt;/em&gt; pathogens, with roles for vegetative hyphae, zoospores and oospores in the disease. However, there is comparatively little known about many aspects of the biology of &lt;em&gt;P.&amp;nbsp;agathidicida&lt;/em&gt;, such as its host range and disease latency, or about the impact on the disease of abiotic and biotic factors such as soil health and co‐occurring &lt;em&gt;Phytophthora&lt;/em&gt; species. This review discusses current and emerging tools and strategies for surveillance, diagnostics and management, including a consideration of genomic resources, and the role these play in understanding the pathogen and how it causes this deadly disease. Key aspects of indigenous Māori knowledge, which include rich ecological and historical knowledge of kauri forests and a holistic approach to forest health, are highlighted.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>10</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Braithwaite, M.</style></author><author><style face="normal" font="default" size="100%">Bullians, M.S.</style></author><author><style face="normal" font="default" size="100%">Pay, J.M.</style></author><author><style face="normal" font="default" size="100%">Gill, G.S.C.</style></author><author><style face="normal" font="default" size="100%">Hill, C.F.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">A disease survey of cherimoya orchards in Northland, New Zealand.</style></title><secondary-title><style face="normal" font="default" size="100%">16th Biennial Australasian Plant Pathology Conference</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2007</style></year></dates><pub-location><style face="normal" font="default" size="100%">Adelaide</style></pub-location><language><style face="normal" font="default" size="100%">eng</style></language></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Brar, S.</style></author><author><style face="normal" font="default" size="100%">Tabima, J.

It was first isolated in 2008 but had previously been recovered from tanoak (&lt;em&gt;Notholithocarpus densiflorus&lt;/em&gt;) and Douglas‐fir (&lt;em&gt;Pseudotsuga menziesii&lt;/em&gt;) trees in Oregon, USA in 2002. &lt;em&gt;Phytophthora pluvialis&lt;/em&gt; was subsequently described as a new species in 2013 and classified as a clade III &lt;em&gt;Phytophthora&lt;/em&gt; species. The aim of this study was to gain a better understanding of the genetic diversity, population structure and origin of this pathogen. A total of 360 &lt;em&gt;P.&amp;nbsp;pluvialis&lt;/em&gt; isolates were collected from the USA and New Zealand. The genome sequences of two &lt;em&gt;P.&amp;nbsp;pluvialis&lt;/em&gt; isolates were used to identify 27 single nucleotide polymorphism (SNP) markers that were then used to genotype the two populations. The genotypic data showed that the USA population of &lt;em&gt;P.&amp;nbsp;pluvialis&lt;/em&gt; had twice the genetic diversity and a greater number of multilocus genotypes (MLGs) compared to the New Zealand population, with 126 and 24 MLGs, respectively. The majority of the subpopulations within the USA and New Zealand showed linkage disequilibrium. All subpopulations had a negative fixation index, indicating that clonal reproduction is prevalent in both countries. A minimum spanning network (MSN) showed two unique clusters of isolates in the New Zealand population, suggesting two potential introductions of &lt;em&gt;P.&amp;nbsp;pluvialis&lt;/em&gt; into New Zealand from the USA. There was no significant structure within the New Zealand or USA populations. This study provides novel insight into the genetic structure of &lt;em&gt;P.&amp;nbsp;pluvialis&lt;/em&gt; in New Zealand and the USA.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">C.M.

P. kernoviae&lt;/em&gt; was discovered in late 2003 during surveys of woodlands in Cornwall, south-west England, for the presence of another invasive pathogen, &lt;em&gt;P. ramorum. P. kernoviae&lt;/em&gt; is self-fertile (homothallic), having plerotic oogonia, often with distinctly tapered stalks and amphigynous antheridia. It produces papillate sporangia, sometimes markedly asymmetric with medium length pedicels. Its optimum temperature for growth is ca 18 $ınfty$C and upper limit ca 26$ınfty$. Currently, &lt;em&gt;P. kernoviae&lt;/em&gt; is especially noted for causing bleeding stem lesions on mature &lt;em&gt;Fagus sylvatica&lt;/em&gt; and foliar and stem necrosis of &lt;em&gt;Rhododendron ponticum.

Since the 1990s however disease outbreaks have occurred increasingly on ornamental &lt;em&gt;C. lawsoniana&lt;/em&gt; in Europe; and in 2007 the pathogen was discovered in soil around old growth &lt;em&gt;C. obtusa&lt;/em&gt; in Taiwan, where it may be endemic. When the phenotypes of over 150 isolates of &lt;em&gt;P. lateralis&lt;/em&gt; from Taiwan, across the Pacific Northwest (British Columbia to California) and from France, the Netherlands and the UK were compared three growth rate groups were resolved: one slow growing from Taiwan, one fast growing from the Pacific Northwest and Europe and one of intermediate growth from a small area of the UK. Within these growth groups distinct subtypes were identified based on colony patterns and spore metrics and further discriminated in a multivariate analysis. The assumption that the three main growth groups represented phylogenetic units was tested by comparative sequencing of two mitochondrial and three nuclear genes. This assumption was confirmed. In addition two phenotype clusters within the Taiwan growth group were also shown to be phylogenetically distinct. These four phenotypically and genotypically unique populations are informally designated as the Pacific Northwest lineage, the UK lineage, the Taiwan J lineage and the Taiwan K lineage. Their characteristics and distribution are described and their evolution, taxonomic and plant health significance is discussed.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">C.M.

An associated risk that accelerated pathogen evolution may be occurring as a consequence of genetic exchange between introduced, or introduced and resident, fungal pathogens is largely unrecognized. This is, in part, because examples of natural, interspecific hybridization in fungi are very rare. Potential evolutionary developments range from the acquisition of new host specificities to emergence of entirely new pathogen taxa. We present evidence from cytological behavior, additive nucleotide bases in repetitive internal transcribed spacer regions of the rRNA-encoding DNA (rDNA), and amplified fragment length polymorphisms of total DNA that a new, aggressive Phytophthora pathogen of alder trees in Europe comprises a range of heteroploid-interspecific hybrids involving a Phytophthora cambivora-like species and an unknown taxon similar to Phytophthora fragariae. The hybrids marked developmental instabilities, unusual morphological variability, and evidence for recombination in their internal transcribed spacer profiles indicates that they are of recent origin and that their evolution is continuing. The likelihood of such evolutionary events may be increasing as world trade in plants intensifies. However, routine diagnostic procedures currently in use are insufficiently sensitive to allow their detection.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">C.M.

The &lt;em&gt;Phytophthora&lt;/em&gt; resembles &lt;em&gt;P. cambivora&lt;/em&gt; in both its gametangial and sporangial morphology. However, it is distinct from this species in being homothallic rather than outcrossing; in producing a significant proportion of small and sometimes partially developed oogonia; in having a high frequency of oosphere abortion; in having an appressed felty colony type with little or no aerial mycelium; and in exhibiting a lower optimum temperature for growth (c.22.5°C) and lower growth temperature maximum (c.29°C) on carrot agar than &lt;em&gt;P. cambivora&lt;/em&gt; (c.27.5° and 33.5°C respectively). An inoculation test confirmed its pathogenicity to &lt;em&gt;Alnus&lt;/em&gt;. The status of the alder &lt;em&gt;Phytophthora&lt;/em&gt; is discussed. On the basis of its unusual characteristics and unusual host it is suggested that it might be a new or recently introduced organism rather than a previously unrecorded indigenous variant of &lt;em&gt;P. cambivora&lt;/em&gt;.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Brasier, Clive M.</style></author><author><style face="normal" font="default" size="100%">Cooke, David E.L.</style></author><author><style face="normal" font="default" size="100%">Duncan, James M.</style></author><author><style face="normal" font="default" size="100%">Hansen, Everett M.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Multiple new phenotypic taxa from trees and riparian ecosystems in Phytophthora gonapodyides-P. megasperma ITS Clade 6, which tend to be high-temperature tolerant and either inbreeding or sterile</style></title><secondary-title><style face="normal" font="default" size="100%">Mycological Research</style></secondary-title><short-title><style face="normal" font="default" size="100%">Mycological Research</style></short-title></titles><dates><year><style  face="normal" font="default" size="100%">2003</style></year><pub-dates><date><style  face="normal" font="default" size="100%">Jan-03-2003</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://linkinghub.elsevier.com/retrieve/pii/S0953756208611788</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">107</style></volume><pages><style face="normal" font="default" size="100%">277 - 290</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;&lt;em&gt;Phytophthora&lt;/em&gt; isolates associated with &lt;em&gt;Phytophthora&lt;/em&gt; major ITS Clade 6 were grouped into 11 phenotypic taxa.

With the exception of &lt;em&gt;P. gonapodyides&lt;/em&gt; each phenotypic taxon represented an unique ITS lineage. Two isolates morphologically identical to &lt;em&gt;P. gonapodyides&lt;/em&gt; comprised a separate lineage and probably represent another taxon, designated here &lt;em&gt;P.&lt;/em&gt; taxon Salixsoil. &lt;em&gt;P. humicola, P.&lt;/em&gt; sp.

The taxonomy, adaptation and breeding systems of Clade 6 taxa are discussed. They show a strong association with forests and riparian ecosystems, only a limited association with agriculture and an ability to tolerate high temperatures. Also, in contrast to most other &lt;em&gt;Phytophthora&lt;/em&gt; clades, Clade 6 taxa are predominantly sterile or inbreeding in culture. Only one taxon, &lt;em&gt;P.&lt;/em&gt; sp.

Using &lt;em&gt;P. drechsleri&lt;/em&gt; and &lt;em&gt;P. cambivora&lt;/em&gt; testers, 51 of 110 &lt;em&gt;P. ramorum&lt;/em&gt; isolates from across Europe were all shown to be A1s; while 32 of 38 American isolates from across California and southwest Oregon were shown to be A2s. However, these interspecific pairings are complex, unusually slow and unpredictable. A range of culture media and conditions are described that were tested, unsuccessfully, with a view to enhancing the efficiency of the interspecific pairings. In further tests, gametangia were obtained between A1 and A2 isolates of &lt;em&gt;P. ramorum&lt;/em&gt; when juvenile, pre-chlamydospore producing mycelia were mixed together on carrot agar. The gametangia formed in 3–10 d, sparsely to frequently, initially only within the boundaries of the mixed inocula but subsequently in the extended mycelial growth. Chlamydospores were also produced. This inoculum-mixing method, though again sometimes unpredictable, should enhance efficiency of testing for compatibility types and facilitate further studies on whether the sexual outcrossing system of &lt;em&gt;P. ramorum&lt;/em&gt; is functional. Differences between sexual reproduction of &lt;em&gt;P. ramorum&lt;/em&gt; and that of other heterothallic &lt;em&gt;Phytophthora&lt;/em&gt; species are discussed.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Clive M.

They showed similar characteristics including similar sporangial dimensions, colonies with often distinctive petaloid patterns and a silvery appearance, slow growth rates at 20, 25 and 30 °C, and a maximum temperature for growth of about 35°. Most isolates exhibited a similar protein banding pattern distinct from that of &lt;em&gt;P. cryptogea&lt;/em&gt; or &lt;em&gt;P. drechsleri&lt;/em&gt;, and including a characteristic band designated the ‘PG band’. Three isolates deviated from this pattern and two of these also produced chlamydospores and chains of swellings in culture. These isolates might be hybrids related to &lt;em&gt;P. gonapodyides&lt;/em&gt; or a different taxon, in which case ‘&lt;em&gt;P. gonapodyides&lt;/em&gt;’ is polyphyletic.&lt;/p&gt;&lt;p&gt;All the isolates were self-sterile. When paired directly or indirectly via polycarbonate membranes with A2 sexual compatibility types of heterothallic species such as &lt;em&gt;P. cambivora, P. megakarya&lt;/em&gt; or &lt;em&gt;P. meadii&lt;/em&gt;, gametangia were produced which were morphologically characteristic of these species. The range of heterothallic species responding was different from that responding sexually to &lt;em&gt;Trichoderma&lt;/em&gt; volatiles. &lt;em&gt;P. gonapodyides&lt;/em&gt; isolates may be sterile A1 compatibility types able to produce a compatibility substance which induces selfing in the heterothallic A2s.&lt;/p&gt;&lt;p&gt;Three other self-sterile &lt;em&gt;Phytophthora&lt;/em&gt; isolates associated with woody hosts in Britain were a distinct group, with a different colony pattern, a distinct 30° growth optimum and an ability to grow at 37°. Their protein banding pattern was different from that of either &lt;em&gt;P. gonapodyides&lt;/em&gt; or &lt;em&gt;P. cryptogea/P. drechsleri&lt;/em&gt;, but showed similarities to these species. One isolate induced gametangial formation in &lt;em&gt;P. drechsleri&lt;/em&gt; A1 types, the two others were sexually neutral.

Therefore, &lt;em&gt;Phytophthora&lt;/em&gt; species were surveyed at 20 sites in Massachusetts, with 16 occurring in the Connecticut River Valley. Many of the sampled waterways were adjacent to active agricultural lands, yet were buffered by mature floodplain forests composed of &lt;em&gt;Acer, Platanus, Populus&lt;/em&gt; and &lt;em&gt;Ulmus&lt;/em&gt;. Isolates were recovered with three types of baits (rhododendron leaves, pear, green pepper) in 2013 and water filtration in 2014. Overall, 457 isolates of &lt;em&gt;Phytophthora&lt;/em&gt; were recovered and based on morphological characters and rDNA internal transcribed spacer (ITS), β-tubulin (β-&lt;em&gt;tub&lt;/em&gt;) and cytochrome oxidase &lt;em&gt;c&lt;/em&gt; subunit I (&lt;em&gt;cox&lt;/em&gt;1) sequences, 18 taxa were identified, including three new species: &lt;em&gt;P.&lt;/em&gt; taxon intercalaris, &lt;em&gt;P.&lt;/em&gt; taxon caryae and &lt;em&gt;P.&lt;/em&gt; taxon pocumtuck. In addition, 49 isolates representing five species of &lt;em&gt;Phytopythium&lt;/em&gt; also were identified. Water filtration captured a greater number of taxa (18) compared to leaf and fruit baits (12). Of the three bait types rhododendron leaves yielded the greatest number of isolates and taxa, followed by pear and green pepper, respectively. Despite the proximity to agricultural lands, none of the &lt;em&gt;Phytophthora&lt;/em&gt; species baited are considered serious pathogens of vegetable crops in the region. However, many of the recovered species are known woody plant pathogens, including four species in the &lt;em&gt;P. citricola&lt;/em&gt; s.l. complex that were identified: &lt;em&gt;P. plurivora, P. citricola&lt;/em&gt; III, &lt;em&gt;P. pini&lt;/em&gt; and a putative novel species, referred to here as &lt;em&gt;P.&lt;/em&gt; taxon caryae. An additional novel species, &lt;em&gt;P.&lt;/em&gt; taxon pocumtuck, is a close relative of &lt;em&gt;P. borealis&lt;/em&gt; based on &lt;em&gt;cox&lt;/em&gt;1 sequences. The results illustrate a high level of &lt;em&gt;Phytophthora&lt;/em&gt; species richness in the Connecticut River Valley and that major rivers can serve as a source of inoculum for pathogenic &lt;em&gt;Phytophthora&lt;/em&gt; species in the northeast.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Bregant, Carlo</style></author><author><style face="normal" font="default" size="100%">Sanna, Gian Paolo</style></author><author><style face="normal" font="default" size="100%">Bottos, Adriano</style></author><author><style face="normal" font="default" size="100%">Maddau, Lucia</style></author><author><style face="normal" font="default" size="100%">Montecchio, Lucio</style></author><author><style face="normal" font="default" size="100%">Linaldeddu, Benedetto T.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Diversity and Pathogenicity of Phytophthora Species Associated with Declining Alder Trees in Italy and Description of Phytophthora alpina sp. nov</style></title><secondary-title><style face="normal" font="default" size="100%">Forests</style></secondary-title><short-title><style face="normal" font="default" size="100%">Forests</style></short-title></titles><dates><year><style  face="normal" font="default" size="100%">2020</style></year><pub-dates><date><style  face="normal" font="default" size="100%">Aug-05-2020</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://www.mdpi.com/1999-4907/11/8/848/htm</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">11</style></volume><pages><style face="normal" font="default" size="100%">848</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;Extensive decline and mortality events of alder trees have recently been observed in several riparian ecosystems in Italy. Since there is little information about the aetiology of this disease and given the high ecological relevance of riparian ecosystems, an in-depth study was conducted in three sites spanning from the Mediterranean to Alpine regions. From spring 2019 to spring 2020, 261 samples of bleeding cankers, rhizosphere soil and leaves used as baits along waterways were collected and used for &lt;span class=&quot;html-italic&quot;&gt;Phytophthora&lt;/span&gt; isolation. Based on morphology, colony appearance and DNA sequence data, 10 species belonging to 6 clades were identified. These included &lt;span class=&quot;html-italic&quot;&gt;P. plurivora&lt;/span&gt; (84 isolates), &lt;span class=&quot;html-italic&quot;&gt;P. pseudocryptogea&lt;/span&gt; (50), &lt;span class=&quot;html-italic&quot;&gt;P. hydropathica&lt;/span&gt; (18), &lt;span class=&quot;html-italic&quot;&gt;P. gonapodyides&lt;/span&gt; (14), &lt;span class=&quot;html-italic&quot;&gt;P. bilorbang&lt;/span&gt; (13), &lt;span class=&quot;html-italic&quot;&gt;P. pseudosyringae&lt;/span&gt; (12), &lt;span class=&quot;html-italic&quot;&gt;P. lacustris&lt;/span&gt; (11), &lt;span class=&quot;html-italic&quot;&gt;P. acerina&lt;/span&gt; (7), &lt;span class=&quot;html-italic&quot;&gt;P. cactorum&lt;/span&gt; (1) and one isolate of the hybrid &lt;span class=&quot;html-italic&quot;&gt;Phytophthora ×serendipita&lt;/span&gt;. In addition, two new &lt;span class=&quot;html-italic&quot;&gt;Phytophthora&lt;/span&gt; species, one of which is described here as &lt;span class=&quot;html-italic&quot;&gt;Phytophthora alpina&lt;/span&gt; sp. nov., were isolated. The pathogenicity of &lt;span class=&quot;html-italic&quot;&gt;P. alpina&lt;/span&gt; and other species obtained from samples collected in the green alder stand was assessed on 3-year-old seedlings. All species proved to be pathogenic on green alder causing symptoms congruent with field observations. Results obtained have allowed us to expand knowledge about alder decline aetiology. The diversity of pathogenicity of &lt;span class=&quot;html-italic&quot;&gt;Phytophthora&lt;/span&gt; species associated with symptomatic alder trees suggested that no single agent is responsible for the disease, but that it is the result of multiple infections of different &lt;span class=&quot;html-italic&quot;&gt;Phytophthora&lt;/span&gt; species, variable in assemblages among sites.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">8</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>46</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Brooks, F</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Phytophthora palmivora</style></title><tertiary-title><style face="normal" font="default" size="100%">Pests and Diseases of American Samoa</style></tertiary-title></titles><dates><year><style  face="normal" font="default" size="100%">2005</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www2.ctahr.hawaii.edu/adap/ASCC_LandGrant/Dr_Brooks/BrochureNo12.pdf</style></url></web-urls></urls><publisher><style face="normal" font="default" size="100%">American Samoa Community College Community &amp; Natural Resources  Cooperative Research &amp; Extension </style></publisher><volume><style face="normal" font="default" size="100%">Number 12</style></volume><pages><style face="normal" font="default" size="100%">2 pp</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;The organism that caused the 1845-46 Irish Potato Famine was named &lt;em&gt;Phytophthora&lt;/em&gt;, the “plant destroyer”.

There are about 80 species of &lt;em&gt;Phytophthora&lt;/em&gt;, all damaging to plants. One of the most common tropical species is &lt;em&gt;P. palmivora&lt;/em&gt;, with more than 150 plant hosts.

Isolation was attempted from the inner surface of 81 sterilized discoloured wood panels (6 × 4 cm) from 53 trees. Discolouration mostly extended 1–5 mm into the xylem (75%), but incursions of 6–10 mm (10%) and 10–25 mm (15%) were frequent. Of the wood panels, 81% yielded &lt;em&gt;Phytophthora&lt;/em&gt; spp. In 66 cases, both a wood panel and an overlying phloem panel were sampled. In 56% of these, a &lt;em&gt;Phytophthora,&lt;/em&gt; sp. was isolated from both the wood and the phloem panel. In 23% the &lt;em&gt;Phytophthora&lt;/em&gt; sp. was isolated from the wood panel only and in 8% from the phloem panel only. Small ‘island’ phloem lesions, often in linear arrays adjacent to main lesions, were a common feature of &lt;em&gt;Fagus sylvatica&lt;/em&gt; and &lt;em&gt;Quercus&lt;/em&gt; spp. trees infected with &lt;em&gt;P. ramorum&lt;/em&gt; or &lt;em&gt;P. kernoviae&lt;/em&gt;. Island lesions were often connected by underlying strips or intermittent pits of discoloured xylem in line with the wood grain. &lt;em&gt;Phytophthora ramorum, P. kernoviae&lt;/em&gt; and other &lt;em&gt;Phytophthora&lt;/em&gt; spp. were successfully isolated from these connecting xylem features with &lt;em&gt;P. ramorum&lt;/em&gt; and &lt;em&gt;P. kernoviae&lt;/em&gt; also recovered from discoloured tissue 5–25 mm below exposed xylem surfaces 24–27 months after the overlying phloem was removed. These results show that these pathogens commonly occupy xylem beneath phloem lesions; that they can perennate in xylem tissue; that they can spread in xylem tissue ahead of phloem lesions; and indicate that they may initiate new phloem lesions in this way. Such colonization must lead to at least local xylem dysfunction. It is recommended that, if xylem discoloration is present, isolation of the &lt;em&gt;Phytophthora&lt;/em&gt; sp. should be attempted from the xylem as well as the bark; also, that removal of infected outer sapwood should be undertaken during excision of bleeding lesions for disease control and in protocols aimed at preventing national or international spread of these tree stem pathogens.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Buddenhagen, I.

Conversely, there are regions thought to be suitable for the pathogen where no disease is observed. We developed a CLIMEX model for the global distribution of &lt;em&gt;P. cinnamomi&lt;/em&gt; based on the pathogen's response to temperature and moisture and by incorporating extensive empirical evidence on the presence and absence of the pathogen. The CLIMEX model captured areas of climatic suitability where &lt;em&gt;P. cinnamomi&lt;/em&gt; occurs that is congruent with all available records. The model was validated by the collection of soil samples from asymptomatic vegetation in areas projected to be suitable by the model for which there were few records. DNA was extracted and the presence or absence of &lt;em&gt;P. cinnamomi&lt;/em&gt; determined by high throughput sequencing (HTS). While not detected using traditional isolation methods, HTS detected &lt;em&gt;P. cinnamomi&lt;/em&gt; at higher elevations in eastern Australia and central Tasmania as projected by the CLIMEX model. Further support for the CLIMEX model was obtained by using the large dataset from southwest Australia where the proportion of positive records in an area is related to the Ecoclimatic Index value for the same area. We provide for the first time a comprehensive global map of the current &lt;em&gt;P. cinnamomi&lt;/em&gt; distribution, an improved CLIMEX model of the distribution, and a projection to 2080 of the distribution with predicted climate change.

In addition to &lt;em&gt;P. cinnamomi&lt;/em&gt;, six morpho-species have been identified using this technique: &lt;em&gt;P. citricola, P. megasperma, P. cryptogea, P. drechsleri, P. nicotianae&lt;/em&gt;, and &lt;em&gt;P. boehmeriae&lt;/em&gt;. In recent years, many new &lt;em&gt;Phytophthora&lt;/em&gt; species have been described worldwide, often with similar morphology to existing species; thus, as many of the isolates collected in Western Australia have been difficult to identify based on morphology, molecular identification of the morpho-species is required. Based on amplification of the internal transcribed spacer (ITS) region of the rDNA gene, sequence data of more than 230 isolates were compared with those of existing species and undescribed taxa. &lt;em&gt;P. inundata, P. asparagi, P.&lt;/em&gt; taxon PgChlamydo, &lt;em&gt;P.&lt;/em&gt; taxon personii, and &lt;em&gt;P.&lt;/em&gt; taxon niederhauserii were identified based on sequence data. Phylogenetic analysis revealed that nine potentially new and undescribed taxa can be distinguished. Several of the new taxa are morphologically indistinguishable from species such as &lt;em&gt;P. citricola, P. drechsleri&lt;/em&gt;, and &lt;em&gt;P. megasperma&lt;/em&gt;. In some cases, the new taxa are closely related to species with similar morphology (e.g., P.sp.4 and &lt;em&gt;P. citricola&lt;/em&gt;). However, the DNA sequences of other new taxa such as P.sp.3 and P.sp.9 show that they are not closely related to morphologically similar species &lt;em&gt;P. drechsleri&lt;/em&gt; and &lt;em&gt;P. megasperma&lt;/em&gt;, respectively. Most of the new taxa have been associated with dying &lt;em&gt;Banksia&lt;/em&gt; spp., while P.sp.2 and P.sp.4 have also been isolated from dying &lt;em&gt;Eucalyptus marginata&lt;/em&gt; (jarrah). Some taxa (P.sp.3, 6, and 7) appear to have limited distribution, while others like P.sp.4 are widespread.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Burgess, Treena I.</style></author><author><style face="normal" font="default" size="100%">López‐Villamor, án</style></author><author><style face="normal" font="default" size="100%">Paap, Trudy</style></author><author><style face="normal" font="default" size="100%">Williams, Briony</style></author><author><style face="normal" font="default" size="100%">Belhaj, Rajah</style></author><author><style face="normal" font="default" size="100%">Crone, Michael</style></author><author><style face="normal" font="default" size="100%">Dunstan, William</style></author><author><style face="normal" font="default" size="100%">Howard, Kay</style></author><author><style face="normal" font="default" size="100%">Hardy, Giles E.

Here, we concentrate on those species that are dispersed through soil and water, attacking the roots of the plants, causing them to rot and die. The intention of this study was to compare the soil baiting protocol developed by the Centre for Phytophthora Science and Management (CPSM) with two other baiting methods used in Australia. The aim was to demonstrate the effectiveness of each protocol for soil baiting &lt;em&gt;Phytophthora&lt;/em&gt; species in different substrates. Three experiments were conducted: the first to test the sensitivity of each method to detect &lt;em&gt;Phytophthora cinnamomi&lt;/em&gt;, the second to test the effect of substrate type (sand or loam), and the third to test the detection of species (&lt;em&gt;P. cinnamomi&lt;/em&gt;, &lt;em&gt;P. multivora&lt;/em&gt;, or &lt;em&gt;P. pseudocryptogea&lt;/em&gt;). The specificity of different plant species baits was compared within and between the methods. Substrate type influenced isolation in all methods; however, the CPSM method was superior regardless of substrate, albeit slower than one of the other methods for one substrate. Comparing bait species between the three methods, &lt;em&gt;Quercus ilex&lt;/em&gt; was the most attractive bait for &lt;em&gt;P. cinnamomi&lt;/em&gt;, particularly in the CPSM method. The choice of protocol affected the isolation associated with each bait type. Overall, the multiple bait system used by CPSM was shown to provide the most sensitive and reliable detection of &lt;em&gt;Phytophthora&lt;/em&gt; species from soil samples.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Butler, EJ</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Report of the imperial mycologist, 1918–1919</style></title><secondary-title><style face="normal" font="default" size="100%">Science Report Institute Pusa</style></secondary-title></titles><pages><style face="normal" font="default" size="100%">82 pp</style></pages><language><style face="normal" font="default" size="100%">eng</style></language></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>10</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Butler, EJ</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Bud rot of coconut and other palms</style></title><secondary-title><style face="normal" font="default" size="100%">Report of Imperial Botanical Conference</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">1924</style></year></dates><pages><style face="normal" font="default" size="100%">145-147</style></pages><language><style face="normal" font="default" size="100%">eng</style></language></record></records></xml>
