Role of transposons for virulence of necrotrophic plant pathogen (Botrytis cinerea)

The Botrytis cinerea is a heterothallic filamentous plant pathogenic ascomycete. Its control at the crop level is still very difficult to achieve. Population genetic analysis revealed a high level of genetic diversity and lack of gene flow among cryptic species of B. cinerea. Presence of transposable elements is found as an active part in dispersal and variability of the fungi. Presence or absence of transposons in B. cinerea were found to affect pathogenic potential of the fungus and might play a role in speciation. Research leading to more insight into the presence/absence of transposons can prompt innovative approaches to control B. cinerea.
