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.

The role of cytokinins in clubroot formation
Physiological Plant Pathology, 1971Abstract The occurrence of cytokinins in healthy turnips (Brassica campestris L. var. rapa “Gelria”) and in turnips infected with Plasmodiophora brassicae has been studied. Extracts of clubroots were about three times as active in cytokinin bioassays as extracts of healthy turnips.

Genetics of Clubroot Resistance in Brassica Species
Journal of Plant Growth Regulation, 2009Clubroot disease, caused by the obligate plant pathogen Plasmodiophora brassicae Wor., is one of the most economically important diseases affecting Brassica crops in the world. The genetic basis of clubroot resistance (CR) has been well studied in three economically important Brassica species: B. rapa, B. oleracea, and B. napus. In B.

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.

GLUCOSINOLATE CONTENT AND CLUBROOT OF RUTABAGA AND TURNIP
Canadian Journal of Plant Science, 1980The glucosinolate content of 22 cultivars of rutabaga (Brassica napobrassica Mill.) and 21 cultivars of turnip (B. rapa L.) was determined. Wide variations were found in total and individual glucosinolates. Three major volatile isothiocyanates and their corresponding nitriles were formed from glucosinolate hydrolysis. These compounds contribute to the

Boron reduces development of clubroot in canola
Canadian Journal of Plant Pathology, 2011Abstract Boron (B) slows the development of Plasmodiophora brassicae (clubroot) during infection of root hairs (primary infection) and the root cortex (secondary infection) of several vegetable Brassica spp., but the impact of B application on clubroot development in canola has not been assessed.

Host–parasite interactions in clubroot of crucifers
Canadian Journal of Plant Pathology, 2014AbstractClubroot, caused by Plasmodiophora brassicae, is an important root disease of crucifers worldwide. In this review, the molecular aspects of clubroot pathogenesis and resistance are discussed. Topics covered include recent studies on the processes associated with infection by primary and secondary pathogen zoospores, examination of the ...

RICHELAIN: A CLUBROOT-RESISTANT CABBAGE CULTIVAR
Canadian Journal of Plant Science, 1989The Richelain cabbage is a newly released cultivar for the fresh market. It is resistant to races 2, 6 and 7 (Williams 1966) or ECD 16/02/31 and 16/02/30 (Buczacki et al. 1975) of the clubroot pathogen, Plasmodiophora brassicae Wor. Slightly ovate heads with dark blue green crinkly leaves and near white internal color are some other features of this ...
