Secretome Analysis of Identifies an Array of Putative Virulence Factors Responsible for Charcoal Rot Disease in Plants.

is a global devastating necrotrophic fungal pathogen. It causes charcoal rot disease in more than 500 host plants including major food crops, pulse crops, fiber crops, and oil crops. Despite having the whole-genome sequence of , understanding the genome-based plant-pathogen interactions is limited in the absence of direct experimental proof of secretion. Thus, it is essential to understand the host-microbe interaction and the disease pathogenesis, which can ensure global agricultural crop production and security. An -predicted secretome of is unable to represent the actual secretome. We could identify 117 proteins present in the secretome of using liquid chromatography-electrospray ionization-tandem mass spectrometry. Data are available ProteomeXchange with identifier PXD032749. An array of putative virulence factors of were identified in the present study using solid-state culture. Similar virulence factors have been reported in other plant pathogenic fungi also. Among the secretory fungal proteins with positive economic impacts, lignocellulolytic enzymes are of prime importance. Further, we validated our results by detecting the cell wall-degrading enzymes xylanase, endoglucanase, and amylase in the secretome of . The present study may provide a better understanding about the necrotrophic fungi , which modulate the host plant defense barriers using secretory proteins.
