Research progress in the mechanism of rhizosphere micro-ecology in regulating the occurrence of clubroot disease in Chinese cabbage

Abstract:

Chinese cabbage clubroot is a common soil-borne disease caused by Plasmodiophora brassicae Woron, which mainly damages the roots of Chinese cabbage. Rhizosphere is the most active key micro-domain of plant-soil-microbiome interaction, and the microbial imbalance in rhizosphere is a primary factor leading to soil-borne diseases. Deciphering the interaction mechanism between rhizosphere micro-ecology and soil-borne diseases is beneficial for finding safe and effective ways for the control of soil-borne diseases by rhizosphere microorganisms, disease-inhibiting substances, and functional metabolism. This paper introduced the relationship between rhizosphere micro-ecology and the occurrence of Chinese cabbage clubroot and expounded the mechanism of rhizosphere microorganisms in regulating the occurrence of clubroot disease in Chinese cabbage from the harm of the disease, rhizosphere microecology, and biocontrol strains. This review is expected to provide a theoretical basis for the control of clubroot disease in Chinese cabbage, improve soil health, and maintain the rhizosphere microecosystem stability.
