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

FINE STRUCTURE OF PLASMODIOPHORA BRASSICAE IN SPOROGENESIS
Canadian Journal of Botany, 1967The vegetative Plasmodium of Plasmodiophora brassicae is contained within host cell cytoplasm. The multinucleate Plasmodium contains numerous large lipid droplets and is replete with mitochondria, dictyosomes, endoplasmic reticulum, and ribosomes. A 250 Å thick osmiophilic plasmodial envelope is characteristic of the vegetative Plasmodium.

Evidence for the growth of Plasmodiophora brassicae in vitro
Mycological Research, 1996Plasmodiophora brassicae is a root-invading pathogen that causes club root disease of brassica crops. Although generally regarded as an obligate biotroph, a number of reports over the last century have suggested that the organism may have a free living saprotrophic amoebal stage. Here we present new evidence to support the contention that P.

Role of Brassica rapa SWEET genes in the defense response to Plasmodiophora brassicae
Genes & GenomicsInteractions of plants with biotic stress factors including bacteria, fungi, and viruses have been extensively investigated to date. Plasmodiophora brassicae, a protist pathogen, causes clubroot disease in Cruciferae plants. Infection of Chinese cabbage (Brassica rapa) plants with P.

Spore wall proteins of Plasmodiophora brassicae
Transactions of the British Mycological Society, 1983Intact resting spores and purified spore walls of Plasmodiophora brassicae were treated with a range of detergents and other reagents and the resultant extracts fractionated by electrophoresis on polyacrylamide gels under denaturing conditions. Some proteins appeared to be bound to the wall by charge or salt linkages, and some were possibly in ...

Sterols in resting spores of Plasmodiophora brassicae
Phytochemistry, 1970Abstract Sterols have been isolated from resting spores of Plasmodiophora brassicae and from healthy root material of various members of the Cruciferae. The results suggest that the parasite may draw upon the host plant for at least part of its sterol requirement.

Assessment of resistance to Plasmodiophora brassicae in swedes
Plant Pathology, 1987A method is described in which swede seedlings inoculated with standardized concentrations of resting spores of specific populations of Plasmodiophora brassicae can be evaluated for resistance in different environments.
