Study of Plasmodiophora brassicae Wor.
2011Reports concerning the life history of Plasmodiophora brassicae Wor. are highly conflicting. The contradictions in the literature on the subject and the difficulties encountered in the initial phase of the present investigation brought about an inquiry into the techniques employed by previous workers.

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.

Infection of Arabidopsis thaliana by Plasmodiophora brassicae
Journal of Phytopathology, 1991AbstractThree populations of Arabidopsis thaliana (L.) Heynh. were inoculated with three isolates of Plasmodiophora brassicae Woron. Inoculation of young Arabidopsis plants caused clubbing of roots and, in the late flowering population CrGC 9–4, infection of shoots.

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 ...

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.

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.

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.

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.
