Co-localisation of the blackleg resistance genes Rlm2 and LepR3 on Brassica napus chromosome A10

摘要

BackgroundThe protection of canola (Brassica napus) crops against blackleg disease, caused by the fungal pathogen Leptosphaeria maculans, is largely mediated by race-specific resistance genes (R-genes). While many R-genes effective against blackleg disease have been identified in Brassica species, information of the precise genomic locations of the genes is limited.
