“…sclerotia (Figures 1-3, Supplementary Table 1). This intraspecies variation in B. cinerea is well documented (Martinez et al, 2003;Mirzaei et al, 2009) and can be influenced by environmental factors. As Botrytis is an important pathogen in greenhouse plant production, changes in the greenhouse environment might also lead to phenotypic variations.…”

“…cinerea isolates show phenotypic and genetic variability. Differences in colony morphology, mycelial growth, sporulation intensity, sclerotia formation, and pathogenicity have been described (Di Lenna et al, 1981;Martinez et al, 2003;Khazaeli et al, 2010;Pande et al, 2010;Kuzmanovska et al, 2012;Kumari et al, 2014). B. cinerea produces a battery of extracellular enzymes, including pectinases and pectin methylesterases (Reignault et al, 1994).…”

Phenotypic Variation of Botrytis cinerea Isolates Is Influenced by Spectral Light Quality

Botrytis cinerea, a fungal pathogen that causes gray mold, displays a high degree of phenotypic diversity. Light emitting diodes (LEDs) with specific light spectrum are increasingly used as lighting resource for plant greenhouse production. The chosen light spectrum can also have an effect on the pathogens in this production system. In this study, we investigated the phenological diversity in 15 B. cinerea isolates upon different light treatments. Daylight, darkness, and LED lights with different wavelengths (white, blue, red, blue+red) were chosen as treatments. The 15 Botrytis isolates differed in their mycelial growth rate, conidia production, and sclerotia formation. Light quality had a limited effect on growth rate. All isolates sporulated under daylight treatment, red light resulted in lower sporulation, while white, blue, and blue+red light inhibited sclerotia formation in all isolates, and sporulation in most, but not all isolates. Pathogenicity of the Botrytis isolates was studied on 2-week-old strawberry (Fragaria × ananassa 'Elsanta') leaves grown under white, blue, and red LED lights. The isolates differed in virulence on strawberry leaves, and this was positively correlated to oxalic acid production by B. cinerea in vitro. Red LED light improved leaf basal resistance to all the tested Botrytis isolates. Blue light pretreatment resulted in decreased leaf resistance to some isolates. Furthermore, we used image analysis to quantify the virulence of the different Botrytis isolates based on changes in photosynthetic performance of the strawberry leaves: chlorophyll fluorescence (F v /F m), chlorophyll index (ChlIdx) and anthocyanin content (modified anthocyanin reflection index, mAriIdx). F v /F m showed a strong negative correlation with disease severity and can be an indicator for the early detection of gray mold on strawberry leaves.

“…Botrytis cinerea not only has a broad host range, but also shows considerable phenotypic variability in vegetative growth, conidiation and sclerotium formation (Kerssies et al 1997;Martinez et al 2003;Schumacher et al 2013). Numerous studies have documented a similar variability in genotypic characters, such as amplified restriction length polymorphism, detection of transposable elements and microsatellite heterogeneity.…”

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,

“…Transposa has two types of transposable elements: boty [10] and flipper [11], whereas these two elements are absent in vacuma. Furthermore, it was shown that the transposa isolates did not differ in pathogenicity from the vacuma isolates [12]. Recently, molecular studies of different nuclear genes have suggested that B. cinerea populations are grouped into two different clades: group I and group II, phylogenetic species [13] [14].…”

Gray mold causes considerable economic losses of fruit and vegetable production. The current study on Egyptian population structure of Botrytis cinerea demonstrates that this species is composed of four TE genotypes: transposa, vacuma, boty and flipper types using transposable elements and sensitivity to the hydroxyanilide fungicide, fenhexamid. The results show that transposa is the predominant isolate type (63.6%) in the sampled populations of B. cinerea. However, the four isolate types are fenhexamid-sensitive regardless of location, host plant and plant organ. Additionally, B. cinerea isolates collected from different host plants do not exhibit any host preference using artificial infection test on lettuce. Furthermore, no relation is found between isolate type and aggressiveness and no divergence event has occurred among the isolates collected from different locations and host plants. The results suggest that host specialization of B. cinerea has not been occurred in the current sampled crops.
