Abstract:

Clubroot,caused by the obligate biotrophic protist Plasmodiophora brassicae Woronin,is a soil-borne pathogen that has emerged as one of the most devastating diseases in global Brassica crop production. Notably,the geographical distribution of infected areas has exhibited a significant expansion trend in recent years. Therefore,systematically elucidating the molecular pathogenesis of P. brassicae and the regulatory mechanisms of host immune response networks in Brassica species is critical for breeding resistant cultivars and establishing integrated disease management systems. Currently,leveraging breakthroughs in high-throughput sequencing technologies and the exponential growth of multi-omics data,researchers have unveiled the molecular atlas of the P. brassicae-Brassica host interaction interface from multidimensional perspectives. This review comprehensively synthesizes key advancements in the field,with a focus on the pivotal role of integrated multi-omics approaches in deciphering the pathogen’s biological characteristics,genetic mapping of resistance genes,and decoding host-pathogen interaction mechanisms. The findings aim to provide theoretical foundations and technical pathways for developing targeted molecular breeding strategies and innovative disease control strategies against clubroot.
