A genome resource for 192 Verticillium dahliae isolates infecting potatoes across Canada

Abstract

Verticillium dahliae is an important soilborne pathogen causing Verticillium wilt. It is also the primary causal agent of potato early dying, a disease complex involving the root-lesion nematode. Here, we report the whole-genome sequencing of 192 isolates of V. dahliae originating from the major potato production areas across Canada. Our results yielded a resource of 277,010 genetic variations that will be useful for genetic analyses and revealed the presence of two major lineages, both present in all provinces but exhibiting differences in regional prevalence.
