Characterization of isolates derived from single resting spores of Plasmodiophora brassicae and studies of their interaction

Abstract: A technique for inoculation of Brassica seedlings with single resting spores of Plasmodiophora brassicae is described. Three isolates derived from single spores were produced from one population of P. brassicae. They gave different reactions with the European Clubroot Differential (ECD) series, and two gave different reactions from those of the spore suspensions from which they were derived. When two isolates were mixed together, spores of one isolate restricted infection by spores of the other isolate.

“…A comparative study between resistance and susceptibility is not possible for the interaction of P. brassicae with A. thaliana, as almost all the A. thaliana ecotypes tested so far are susceptible to P. brassicae (Siemens et al 2002;Agarwal et al 2009). Also, the enormous variation in the virulence of P. brassicae populations reported worldwide (Jones et al 1982) often makes it difficult to determine the host's genomic and metabolomic responses.…”

“…Jones Jones et al (1982bJones et al ( ) (1982b também se depararam com a mesma problemática, pois apenas três plantas de B. campestris var. pekinensis cv Granaat (suscetível) apresentaram hérnias quando inoculadas monosporicamente, considerando-se as 450 inoculadas menos de 1% de sucesso foi obtido utilizando esta técnica.…”

“…Estes resultados mostram que populações (isolados) coletadas de um mesmo local, em períodos e hospedeiros diferentes, como os isolados 10 e 11, são geneticamente diferentes, provavelmente resultante dos cruzamentos entre os possíveis distintos patótipos existentes dentro de uma mesma área e população de P. brassicae (Jones et al, 1982b). E isso nos leva a crer que hospedeiros resistentes, a uma determinada população de uma região, pode ter sua resistência alterada em regiões de cultivo próximas, pois cada população é evidentemente variável quanto à patogenicidade, indicando a necessidade de estudos mais detalhados para que essa variabilidade patogênica seja contornada e cultivares de brássicas com maior grau de resistência sejam desenvolvidas.…”

“…Heterogeneity of the P. brassicae population was confirmed using singlespore derived isolates (Jones and Ingram, 1982;Manzanares et al, 1996). Various classification methods of clubroot isolates have been established using different indicator plants (Buczacki et al, 1975;Crute et al, 1980;Williams, 1966).…”
