SnRK1.1-mediated resistance of Arabidopsis thaliana to clubroot disease is inhibited by the novel Plasmodiophora brassicae effector PBZF1.

ABSTRACT: Plants have evolved a series of strategies to combat pathogen infection. Plant SnRK1 is probably involved in shifting carbon and energy use from growth-associated processes to survival and defence upon pathogen attack, enhancing the resistance to many plant pathogens. The present study demonstrated that SnRK1.1 enhanced the resistance of Arabidopsis thaliana to clubroot disease caused by the plant-pathogenic protozoan Plasmodiophora brassicae. Through a yeast two-hybrid assay, glutathione S-transferase pull-down assay, and bimolecular fluorescence complementation assay, a P. brassicae RxLR effector, PBZF1, was shown to interact with SnRK1.1. Further expression level analysis of SnRK1.1-regulated genes showed that PBZF1 inhibited the biological function of SnRK1.1 as indicated by the disequ
