Open AccessSystematic characterization of Brassica napus UBC13 genes involved in DNA-damage response and K63-linked polyubiquitination
Ubc13 is the only known ubiquitin conjugating enzyme (Ubc/E2) dedicated to promoting Lys (K)63-linked polyubiquitination, and this process requires a Ubc/E2 variant (UEV). Unlike conventional K48-linked polyub...

Open AccessIdentification of resistance loci against new pathotypes of Plasmodiophora brassicae in Brassica napus based on genome-wide association map**
Genetic resistance is a successful strategy for management of clubroot (Plasmodiophora brassicae) of brassica crops, but resistance can break down quickly. Identification of novel sources of resistance is especia...

Open AccessGenome-wide transcriptome reveals mechanisms underlying Rlm1-mediated blackleg resistance on canola
Genetic resistance to blackleg (Leptosphaeria maculans, Lm) of canola (Brassica napus, Bn) has been extensively studied, but the mechanisms underlying the host–pathogen interaction are still not well understood. ...

Open AccessTranscriptome analysis identified the mechanism of synergy between sethoxydim herbicide and a mycoherbicide on green foxtail
Certain synthetic herbicides can act synergistically with specific bioherbicides. In this study, a sethoxydim herbicide at 0.1× label rate improved biocontrol of herbicide-sensitive green foxtail (Setaria viridis...

Open AccessAnalysis of genome-wide variants through bulked segregant RNA sequencing reveals a major gene for resistance to Plasmodiophora brassicae in Brassica oleracea
Two cabbage (Brassica oleracea) cultivars ‘Tekila’ and ‘Kilaherb’ were identified as resistant to several pathotypes of Plasmodiophora brassicae. In this study, we identified a clubroot resistance gene (Rcr7) in ...

Breakdown of Rlm3 resistance in the Brassica napus–Leptosphaeria maculans pathosystem in western Canada
Blackleg disease, caused by the fungal pathogen Leptosphaeria maculans, is a serious disease of Brassica napus. The disease is mainly controlled by genetic resistance and crop rotation. However, L. maculans has d...
