Abstract

Verticillium is a genus of ascomycete fungi that encompasses several plant pathogenic species, and cause severe annual yield losses on many economically important crops worldwide. One of the most important species in this genus, is V. longisporum, which causes disease mainly on plants in the Brassicaceae family. Genome analysis of V. longisporum strain VL1 revealed a number of candidate effector genes that may be associated with fungal virulence. One of these candidate effector-genes encodes a putative endolysin-like protein. Endolysins are hydrolytic enzymes that are secreted by bacteriophages and recently, they have been identified in fungal genomes as well. In this study, the potential role of this gene has been investigated in V. longisporum. Our data showed that this gene was highly induced in the fungus during Brassica napus infection and its overexpression significantly increased V. longisporum virulence, indi-cating an involvement in the fungal infection process.(c) 2022 The Authors.
