Clubroot, caused by Plasmodiophora brassicae Woronin, is an important soilborne disease of canola (oilseed rape; Brassica napus L.). In Canada, clubroot management relies heavily on the planting of resistant cultivars, but since 2013, resistance has been broken in an increasing number of fields. Prior to the introduction of resistance, P.

Resistance of Raphanobrassica to Clubroot Disease
Nature, 1973THE classical amphidiploid Raphanobrassica (2n = 36, genomic formula rrcc), first reported by Karpechenko1, was of considerable academic interest and appears in many textbooks. As far as is known Raphanobrassica does not occur in the wild and it has not been exploited practically.

Metabolic cost of resistance in clubroot-resistant canola and napa cabbage
Canadian Journal of Plant Pathology, 2017AbstractGenetic resistance is widely used to manage clubroot (Plasmodiophora brassicae) in canola (Brassica napus) and other brassica crops. Replicated field trials were conducted with three clubroot-resistant cultivars and one susceptible cultivar of either canola or napa cabbage (B. rapa) in southern Ontario in 2014 and 2015.

Quantitative Trait Loci for Clubroot Resistance in Brassica oleracea
2003Clubroot, caused by the fungus Plasmodiophora brassicae Wor., is one of the most damaging diseases of Brassica oleracea crops, including cauliflower, broccoli, Brussels sprouts, cabbage, and other cruciferous crops worldwide. The pathogen causes swelling of parts of the roots and sometimes of the stem base, giving rise to the characteristic “clubs” for

Studies into clubroot (Plasmodiophora brassicae) epidemiology and resistance
2021Clubroot, caused by Plasmodiophora brassicae, is an important soilborne disease of canola (oilseed rape; Brassica napus). The effective and sustainable management of clubroot requires a deeper understanding of clubroot epidemiology and improved durability of host resistance. This research aimed to (i) develop a clubroot yield loss model for B.

Theoretical and Applied Genetics, 2010
To perform comparative studies of CR (clubroot resistance) loci in Brassica oleracea and Brassica rapa and to develop marker-assisted selection in B. oleracea, we constructed a B. oleracea map, including specific markers linked to CR genes of B. rapa.

Genetics of clubroot (Plasmodiophora brassicae) disease resistance in Brassica
2021Clubroot disease, caused by Plasmodiophora brassicae, is a major threat to canola production. Cultivation of resistant cultivars is the key component in managing this disease. Canola is an important oilseed crop in the world; this includes the allopolyploid species Brassica napus L. (AACC genome, 2n = 38) and B. juncea L. (AABB genome, 2n = 36) and the

Clubroot resistance QTL are modulated by nitrogen input in Brassica napus
Theoretical and Applied Genetics, 2017Nitrogen levels can modulate the effectiveness of clubroot resistance in an isolate- and host-specific manner. While the same QTL were detected under high and low nitrogen, their effects were altered. Clubroot, caused by Plasmodiophora brassicae, is one of the most damaging diseases of oilseed rape and is known to be affected by nitrogen fertilization.

Arabidopsis ecotype screening reveals novel sources of clubroot resistance
Plant DiseaseClubroot, caused by Plasmodiophora brassicae, poses a persistent threat to Brassicaceae crops, particularly in regions where resistant cultivars are under strong selection pressure. To identify new sources of resistance and better understand the underlying genetic mechanisms, we evaluated 60 Arabidopsis thaliana ecotypes against the highly virulent ...
