Botrytis cinerea can affect any part of lettuce causing extensive damage and huge loss in production worldwide. Therefore, there is a high need to investigate such pathogen characteristics based on hyperspectral analysis and to evaluate spectral features for the identification and discrimination of B. cinerea at isolate level. Spectral reflectance patterns of different isolates of B. cinerea were carried out indoor and compared with that of molecular ones. Moreover, spectral patterns and… Expand
Detection and Characterization of Botrytis cinerea Isolates from Vegetables in Egypt
Diversity in phenotypic, pathological and molecular characteristics was detected among isolates, leading to categorizing them into different groups, and vacuma  population demonstrated the lowest pathogenic potential comparing to others. Expand
Molecular and Pathological Variability Associated with Transposable Elements of Botrytis Cinerea Isolates Infecting Grape and Strawberry in Egypt
The present work demonstrated a correlation between the distribution of TEs and some fungal features such as isolate source and virulence, but no correlation was found between morphological characteristics, TE type, and sensitivity to fenhexamid. Expand
Effects of Some Plant Extracts, Bioagents, and Organic Compounds on Botrytis and Sclerotinia Molds
Most of the tested potential biofungicide treatments tended to reduce mold infections, and some of them, such as Cin, exhibited a higher inhibitory effect in vitro than the others. Expand


Spectral footprint of Botrytis cinerea , a novel way for fungal characterization
The spectral signatures of different B. cinerea isolates as well as various fungal genera were determined and a unique spectral pattern was investigated at both genus and isolate level. Expand
Characterization of Egyptian Botrytis cinerea Isolates from Different Host Plants
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. Expand
Sexual recombination in the Botrytis cinerea populations in Hungarian vineyards.
Application of the index of association, the chi-square test, and the phi test consistently indicated that the population of Hungarian isolates of B. cinerea undergoes sexual reproduction, and a low or occasionally moderate level of fixation in the Flipper populations. Expand
Early detection of gray mold in grape using conventional and molecular methods
A dual system for the detection, isolation and quantification of B. cinerea and real time polymerase chain reaction/real-time quantitative PCR (PCR/qPCR) proved to be selective and sensitive assays and should be used to monitor Botrytis infection in the field. Expand
The Role of Saprotrophy and Virulence in the Population Dynamics of Botrytis cinerea in Vineyards.
Monitoring of change in relative frequencies of the three main genetic types of Botrytis cinerea found that change in the vacuma and transposa frequencies was most likely caused by differences in saprotrophic and pathogenic fitness. Expand
Genetic Structure of Botrytis cinerea Populations from Different Host Plants in California.
The parsimony tree length permutation (PTLPT) and index of association ( IA) analyses of MP-PCR data set were consistent with absence of sexual recombination in sampled populations of this pathogen. Expand
The increasing requirement for alternative approaches to reduce farmers' dependency on use of fungicides led to the evaluation and exploitation of potential biocontrol agents capable of substantial disease suppression in a commercial context, and within integrated crop management systems. Expand
Characterization of Botrytis cinerea Isolates Present in Thompson Seedless Table Grapes in the Central Valley of Chile.
Botrytis cinerea isolates from flowers and berries of Vitis vinifera 'Thompson seedless' (grapevine) were characterized in terms of two transposable elements (TEs) Boty and Flipper, random amplifiedExpand
Differences in Frequency of Transposable Elements Presence in Botrytis cinerea Populations from Several Hosts in Greece.
Investigation of the presence and frequency distribution of the transposable elements Boty and Flipper in populations of the necrotroph plant pathogen Botrytis cinerea in Greece found that vacuma and transposa isolates had similar mycelial growth rates at the limiting temperatures of 0 and 10°C, while vacuma isolates grew faster at the optimum temperature of 20°C.

New Hyperspectral Discrimination Measure for Spectral Characterization
The spectral angle mapper (SAM) has been widely used in multispectral and hyperspectral image analysis to measure spectral simi- larity between substance signatures for material identification. ItExpand
