This paper uses large-scale transcriptomics to analyze the gene expression of Leptosphaeria maculans over two years of interaction with its host plant, identifying 9% of genes involved in infection stages and revealing their chromatin localization.

The study shows that oilseed rape genotype significantly affects Leptosphaeria maculans fruiting body production, independent of disease severity, using field data across four growing seasons.

The paper characterizes a set of L. maculans isolates on multiple resistance genes and uses them to assess virulence frequencies in a French population, finding some genes remain effective while others have lost efficacy.
