From: Variation in bradyrhizobial NopP effector determines symbiotic incompatibility with Rj2-soybeans via effector-triggered immunity

Fig. 9

Proposed molecular mechanism of Rj2 symbiotic incompatibility. Bradyrhizobia produce Nod factors to activate a signaling cascade (symbiosis [Sym] signaling) leading to nodule organogenesis. In the interaction with Rj2-soybeans, incompatible bradyrhizobia inject the NopP effector having the R60, R67, and H173 residues via T3SS into the host root cell. NopP interacts with the host Rj2 protein with unknown mechanism and activate effector-triggered immunity, which blocks the infection
