Molecular Biology of Plasmodiophora brassicae
Journal of Plant Growth Regulation, 2009Initially, molecular techniques were used to detect and distinguish Plasmodiophora pathotypes in soil. Meanwhile, chromosomes from 2.2 Mb to 680 kb are characterized and the total genome size is estimated to be approximately 20 Mb. Furthermore, the genomic gene structure and the cDNA structure of several genes have been revealed, and the expression of ...

Life Cycle of Plasmodiophora brassicae
Journal of Plant Growth Regulation, 2009Plasmodiphora brassicae is a soil-borne obligate parasite. The pathogen has three stages in its life cycle: survival in soil, root hair infection, and cortical infection. Resting spores of P. brassicae have a great ability to survive in soil. These resting spores release primary zoospores.

Mercury tolerance in Plasmodiophora brassicae
Transactions of the British Mycological Society, 1981Physiologic populations (ECD 16/31/31) of Plasmodiophora brassicae from clubroot-infested fields were found to differ in their sensitivity to mercury. A mercury-tolerant population was isolated from fields where mercurous chloride (calomel) had been used continuously for many years and compared with a mercury-sensitive physiologic population ...

Evaluation of French Brassica oleracea landraces for resistance to Plasmodiophora brassicae
Euphytica, 2000A total of 240 kale, 38 cabbage and 126 winter cauliflower French landraces from the B. oleracea genepool of INRA were assessed for resistance to clubroot caused by Plasmodiophora brassicaeWoron. Two French isolates of the pathogen (K and SJ) were used in the experiments under controlled conditions.

Refining the Life Cycle ofPlasmodiophora brassicae
Phytopathology®, 2020As a soilborne protist pathogen, Plasmodiophora brassicae causes the devastating clubroot disease on Brassicaceae crops worldwide. Due to its intracellular obligate biotrophic nature, the life cycle of P. brassicae is still not fully understood. Here, we used fluorescent probe-based confocal microscopy and transmission electron microscopy (TEM) to ...

Detection and Measurement of Plasmodiophora brassicae
Journal of Plant Growth Regulation, 2009Clubroot, caused by Plasmodiophora brassicae, is one of the most important diseases of brassicas. Management of clubroot is difficult, and the best means of avoiding the disease include planting in areas where P. brassicae is not present and using plants and growing media free from pathogen inoculum. As P. brassicae is not culturable, its detection has

RACES OF PLASMODIOPHORA BRASSICAE
Canadian Journal of Botany, 1957Six races of Plasmodiophora brassicae Wor. have been distinguished on the basis of pathogenicity on differential hosts of cultivated and wild crucifers.Pathogenic differences between isolates were established by replicated tests in the greenhouse under conditions of controlled temperature and moisture.

The ultrastructure of meiosis in Plasmodiophora brassicae (Plasmodiophorales)
Canadian Journal of Botany, 1979Meiosis was examined in plasmodia of the protist Plasmodiophora brassicae within artificially inoculated cabbage roots, using light and electron microscopy. Meiotic nuclear divisions occur following the cessation of vegetative growth of the Plasmodium.

The susceptibility of Brassica oleracea cultivars to Plasmodiophora brassicae (clubroot)
Plant Pathology, 1986An evaluation of 404 Brassica oleracea cultivars for susceptibility to Plasmodiophora brassicae (clubroot) at one field site in northern Scotland over the four years 1979‐82 is reported. The population of P. brassicae

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.
