报告内容简介：
The nitrogen-fixing symbiosis between legume plants and rhizobia is highly relevant to human society and global ecology. Inside the specific root organ, nodule, plant accommodate rhizobia inside its cells and secrete host effectors to regulate rhizobia differentiation and development. However how plants recognize rhizobia specifically and successfully target rhizobia for subcellular trafficking are poorly understood. We demonstrate that SYP132A, a symbiosis-specific SNARE protein isoform, is an ancient factor specifying plant-microbe interfaces. Meanwhile we show that DMI2, a receptor-like kinase, exhibit protein level dynamics to magnify perceived rhizobia signal. Furthermore we identified novel proteins coordinating nodule development and rhizobia infection. Increased understanding of nitrogen-fixing symbiosis could lead to breakthroughs in forage improvement and more sustainable agricultural practice world widely.
