  1. (Institute of Plant Protection, Sichuan Academy of Agricultural Sciences/Key Laboratory of Integrated Pest Management in Southwest Agriculture Crops of Ministry of Agriculture, Chengdu 610066)Abstract: Clubroot disease of cruciferous crops is caused by Plasmodiophora brassicae Woronin, due to long survival time, high infectivity, quick spread speed, diverse spread routes and limited knowledge of life cycle and pathogenic mechanism of P. brassicae, the clubroot disease is increasingly severe in China. The author started with correlational research progress on pathogenic mechanism of P. brassicae, reviewed the relationship of plant hormones (such as auxin, cytokinin, salicylic acid, jasmonic acid, abscisic acid) and secondary metabolite (such as oxidase, glucosinolate, flavonoid, polyamine) and Plasmodiophora brassicae Woronin, analyzed pathogenic processes on Plasmodiophora brassicae Woronin, and main physiological and biochemical reaction in the process of invasion and the change of metabolism. The results could offer reference to the study of the pathogenesis and the prevention and control of Plasmodiophora brassicae Woronin.

Abstract: Clubroot disease, caused by Plasmodiophora brassicae Woronin, has become a major problem in cruciferous crops worldwide. Due to high infection, quick and diverse transmission and limited understanding of life cycle and pathogenic mechanism of P. brassicae, the clubroot disease is increasingly severe. In this article, realted research progress was reviewed on pathogenic mechanism of P. brassicae, including relationships of fungal pathogenicity and second metabolise secondary metabolites of auxin, cytokinin, salicylic acid, jasmonic acid, abscisic acid, and oxidizing enzyme, glucosinolates, flavonoid and polyamines and so on. Their main phisio-chemical reaction and metabolizing variation were analyzed. It will be benefit to future research and providing reference to further control of clubroot disease.
