Mesorhizobium huakuii regulates the microbiome and disease resistance pathways to promote clubroot resistance in rapeseed

Clubroot is a global soilborne disease caused by Plasmodiophora brassicae that severely affects cruciferous crops. The pathogen induces the formation of galls on the roots of host plants, which have detrimental effects on host growth, leading to a significant reduction in yield and quality of cruciferous crops worldwide. This study found that the co-inoculation of rapeseed plants with Mesorhizobium huakuii and P. brassicae significantly reduced the root galls and disease index.
