Symptom severity on differential host lines is currently used to characterize and identify pathotypes of Plasmodiophora brassicae, which is an obligate, soil-borne chromist pathogen that causes clubroot disease on canola (Brassica napus) and other brassica crops. This process is slow, variable and resource intensive; development of molecular markers could make identification of important pathotypes faster and more consistent for deployment of cultivars with pathotype-specific resistance. In the current study, a variant of gene 9171 was identified in the whole-genome sequences of only the highly virulent pathotypes of P.

- Clubroot, caused by the pathogen Plasmodiophora brassicae, affects brassica crops like canola and has shown rapid development of new virulent strains in Canada since its initial identification in 2003.
- A study of 43 P. brassicae strains revealed five genetic clades, with strains from Canadian Prairies forming two distinct groups compared to other regions, highlighting substantial genetic variation.
- The analysis indicates that new virulent pathotypes are likely derived from existing strains and underscore the importance of ongoing monitoring to manage clubroot resistance effectively.
