Plant genomic variation, including presence/absence variation (PAV) and copy number variation (CNV), encompasses genes, especially disease resistance genes. Here, the role of Brassica napus PAV and CNV in disease resistance was characterised. Moreover, the effect of different Leptosphaeria maculans isolates on the expression of qualitative resistance and senescence on B. napus cotyledons was investigated. The findings suggest that PAV and CNV are important sources of genomic variation playing a key role in disease resistance in B. napus. These results provide a useful genomic resource to facilitate further research and advance our understanding of the mechanisms underlying resistance in B. napus.
