Microbe-derived non-necrotic glycoside hydrolase family 12 proteins act as immunogenic signatures triggering plant defenses
文献摘要：
Plant pattern recognition receptors (PRRs) are sentinels at the cell surface sensing microbial invasion and activating innate immune re-sponses. During infection, certain microbial apoplastic effectors can be recognized by plant PRRs, culminating in immune responses accompanied by cell death. However, the intricated relationships between the activation of immune responses and cell death are unclear. Here, we studied the glycoside hydrolase family 12 (GH12) protein, Ps109281, secreted by Phy-tophthora sojae into the plant apoplast during infection. Ps109281 exhibits xyloglucanase activity, and promotes P. sojae infection in a manner dependent on the enzyme activity. Ps109281 is recognized by the membrane-localized receptor-like protein RXEG1 and trig-gers immune responses in various plant species. Unlike other characterized GH12 members, Ps109281 fails to trigger cell death in plants. The loss of cell death induction activity is closely linked to a sequence polymorphism at the N-terminus. This sequence polymorphism does not affect the in planta interaction of Ps109281 with the recognition receptor RXEG1, indicating that cell death and immune response activation are determined using different regions of the GH12 proteins. Such GH12 protein also exists in other Phytophthora and fungal pathogens. Taken to-gether, these results unravel the evolution of effector sequences underpinning different im-mune outputs.
