Comparative transcriptome analysis reveals key pathways and hub genes for the resistance to Plasmodiophora brassicae in rapeseed

Rapeseed (Brassica napus L., AACC, 2n=38) is one of the most important oil crops around the world. With intensified rapeseed cultivation, the incidence and severity of clubroot infected by Plasmodiophora brassicae Wor. (P. brassicae) has increased very fast, which seriously impedes the development of rapeseed industry. Therefore, it is very important and timely to investigate the mechanisms and genes regulating clubroot resistance (CR) in rapeseed. In this study, comparative transcriptome analysis was carried out on two rapeseed accessions of R- (resistant) and S- (susceptible) line.This study not only provides valuable information for CR molecular mechanisms, but also has applied implications for CR breeding in rapeseed.
