Mercury tolerance in Plasmodiophora brassicae

Transactions of the British Mycological Society, 1981
Physiologic 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 ...

The ultrastructure of meiosis in Plasmodiophora brassicae (Plasmodiophorales)

Canadian Journal of Botany, 1979
Meiosis 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.

Refining the Life Cycle ofPlasmodiophora brassicae

Phytopathology®, 2020
As 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 ...

RACES OF PLASMODIOPHORA BRASSICAE

Canadian Journal of Botany, 1957
Six 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 susceptibility of Brassica oleracea cultivars to Plasmodiophora brassicae (clubroot)

Plant Pathology, 1986
An 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

Genetics of clubroot (Plasmodiophora brassicae) disease resistance in Brassica

2021
Clubroot 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

Study of Plasmodiophora brassicae Wor.

2011
Reports 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, 1996
Plasmodiophora 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, 1991
AbstractThree 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, 1983
Intact 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 ...
