Whole genome sequencing reveals the genetic diversity and structure of Leptosphaeria maculans populations from the Western Cape province of South Africa.

ABSTRACT:

Background

Leptosphaeria maculans is the causal agent of blackleg, a globally important disease of canola. Investigating the genetic diversity and structure of L. maculans populations can provide insight into its evolutionary potential and genetic variability, which is important to develop effective blackleg management strategies. In this study, whole genome sequence data was generated for 230 L. maculans isolates collected between 2020 and 2022 across the canola production regions of the Western Cape of South Africa. A total of 27 419 informative single nucleotide polymorphisms was used to investigate the genetic diversity and structure of the pathogen population.

Results

Mating type distribution did not deviate statistically from a 1:1 ratio at any location, indicating no
