Molecular Biology of Plasmodiophora brassicae

Journal of Plant Growth Regulation, 2009
Initially, 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, 2009
Plasmodiphora 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.

Evaluation of French Brassica oleracea landraces for resistance to Plasmodiophora brassicae

Euphytica, 2000
A 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.

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 ...

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 ...

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.

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

Clubroot (Plasmodiophora brassicaeWoronin) – an agricultural and biological challenge worldwide [PDF]

Canadian Journal of Plant Pathology, 2014
Clubroot disease and the causal microbe Plasmodiophora brassicae offer abundant challenges to agriculturists and biological scientists. This microbe is well fitted for the environments which it inhabits.

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
