The paper identifies seven QTL associated with Leptosphaeria maculans adaptation to Brassica species and finds epistasis contributes to transgressive phenotypes in progeny isolates.

This study characterizes the Rlm3 resistance gene in rapeseed, showing it recognizes effectors from multiple fungal pathogens and identifies key regions for recognition.

The paper shows that meiotic recombination in Leptosphaeria maculans produces isolates better adapted to the nonhost Brassica carinata than their parental isolates.

MPSeqM combines multiplex PCR and sequencing to analyze polymorphism in eight AvrLm genes of L. maculans, showing high correlation with pathotyping and enabling large-scale monitoring of virulent isolates.

The paper clones a new avirulence gene, AvrLmS-Lep2, using two independent methods and confirms its role in inducing resistance in Brassica napus.
