Many fungi are pathogenic on plants and cause significant damage in agriculture and forestry. They are also part of the natural ecosystem and may play a role in regulating plant numbers/density. Morphological identification and analysis of plant pathogenic fungi, while important, is often hampered by the scarcity of discriminatory taxonomic characters and the endophytic or inconspicuous nature of these fungi. Molecular (DNA sequence) data for plant pathogenic fungi have emerged as key information for diagnostic and classification studies, although hampered in part by non-standard laboratory practices and analytical methods. To facilitate current and future research, this study provides phylogenetic synopses for 25 groups of plant pathogenic fungi in the Ascomycota, Basidiomycota, Mucormycotina (Fungi), and Oomycota, using recent molecular data, up-to-date names, and the latest taxonomic insights. Lineagespecific laboratory protocols together with advice on their application, as well as general observations, are also provided. We hope to maintain updated backbone trees of these fungal lineages over time and to publish them jointly as new data emerge. Researchers of plant pathogenic fungi not covered by the present study are invited to join this future effort. Bipolaris, Botryosphaeriaceae,

“…In a peony field cultured without fungicide treatments, isolates from rotten stem bases were identified as eight B. paeoniae, six B. pseudocinerea, and two B. cinerea strains. Chocolate spots is a common disease on broad beans, reported to be caused by the host-specific species B. fabae or B. fabiopsis and by B. cinerea (22). For identification of B. fabae, a PCR that detects a B. fabae-specific 122-bp deletion in B. cinerea BC1G_06014 was used (20) (see Fig.…”

cBotrytis cinerea is one of the most important pathogens worldwide, causing gray mold on a large variety of crops. Botrytis pseudocinerea has been found previously to occur together with B. cinerea in low abundance in vineyards and strawberry fields. Here, we report B. pseudocinerea to be common and sometimes dominant over B. cinerea on several fruit and vegetable crops in Germany. On apples with calyx end rot and on oilseed rape, it was the major gray mold species. Abundance of B. pseudocinerea was often negatively correlated with fungicide treatments. On cultivated strawberries, it was frequently found in spring but was largely displaced by B. cinerea following fungicide applications. Whereas B. cinerea strains with multiple-fungicide resistance were common in these fields, B. pseudocinerea almost never developed resistance to any fungicide even though resistance mutations occurred at similar frequencies in both species under laboratory conditions. The absence of resistance to quinone outside inhibitors in B. pseudocinerea was correlated with an intron in cytB preventing the major G143A resistance mutation. Our work indicates that B. pseudocinerea has a wide host range similar to that of B. cinerea and that it can become an important gray mold pathogen on cultivated plants. Botrytis cinerea Pers.:Fr. is one of the most important plant pathogens worldwide, causing gray mold rot on far more than 200 plant species, including cultivated fruits, vegetables, and ornamental flowers. In addition to its wide host range, typical features of B. cinerea are a necrotrophic, macerating mode of infection, abundant production of asexual macroconidia on the surface of colonized host tissue, and formation of melanized sclerotia for long-term survival and sexual reproduction. Control of gray mold often relies on the use of fungicides although the efficacy of such treatments is threatened worldwide by the abundance of fungicide-resistant B. cinerea field strains (1). Based on gene sequence comparisons, the genus Botrytis has been divided into two phylogenetically separate clades (2). Clade 1 includes B. cinerea and B. pseudocinerea as well as the host-specific species B. fabae, B. calthae, and B. sinoviticola; all of these infect only dicot plants. Clade 2 is phylogenetically more diverse and currently comprises 23 host-specific Botrytis species that infect predominantly monocots (2-4).B. cinerea shows considerable variability in mycelial growth phenotype, conidiation, and sclerotium formation. Numerous studies have also documented a high degree of genetic variability within the species. Based on the analysis of PCR-restricted fragment length polymorphism (RFLP) patterns, fungicide resistance, and the detection of transposable elements, Giraud et al. provided evidence of the existence of genetically distinct groups within B. cinerea (5, 6). In particular, the presence or absence of the long terminal repeat retrotransposon Boty (7) and of the DNA transposon Flipper (8) was used to divide isolates into different transposon types, e...

“…So far, 26 species of Botrytis have been described based on these morphological characteristics (Hennebert 1973;Yohalem et al 2003;Wang et al 1996;O'Gorman et al 2008;Zhang et al 2010). Recently, DNA-based molecular techiniques have been widely used to identify fungi, including Botrytis species.…”

A study was conducted to identify Botrytis spp. isolated from bulb onion, green onions, garlic, and garlic chives grown in Hubei Province of China. Based on colony morphology and conidial characteristics, 367 strains of Botrytis spp. were identified as five distinct species, namely, B. cinerea, B. squamosa, B. porri, B. byssoidea, and an undescribed Botrytis species (Botrytis sp.), which accounted for 64.3, 29.9, 3.3, 0.3, and 2.2%, respectively. The previously undescribed species is herein described as a new species, B. sinoallii sp. nov., which is characterized by production of numerous small sclerotia on potato dextrose agar. Phylogenetic analysis using partial sequences of three nuclear genes (G3PDH, HSP60, and RPB2) showed that B. sinoallii forms a unique lineage, which is closely related to B. squamosa, a well-known species on Allium crops, but distantly related to the other species of Botrytis on Allium crops, including B. cinerea, B. porri, B. aclada, B. allii, B. byssoidea, B. globosa, and B. sphaerosperma. Results of inoculation tests showed that B. sinoallii is a newly identified agent that can cause leaf blight of green onion, garlic, and garlic chives. Potential impact of B. sinoallii on production of Allium crops in China is discussed.
