Study of recognition mechanism of pathogenic bacteria in plant

研究了水稻植物免疫应答的诱导机制。几种受体激酶被鉴定为鞭毛蛋白受体。在受体基因破坏突变体中的互补分析表明，FliRK2作为鞭毛蛋白的受体起作用，并且鞭毛蛋白识别信号通过蛋白磷酸化转导到细胞中。我们还发现水稻对鞭毛蛋白的特异性识别受鞭毛蛋白中的^ Ser和^ Ser上的聚糖的调节<178><183>，从而阻止水稻中的表位识别。

We studied the induction mechanism of plant immune responses in rice. Several receptor kinases were identified as flagellin receptor. Complementary analysis in receptor gene-disruption mutants showed that FliRK2 functions as receptor for flagellin and the flagellin recognition signal is transduced through the protein phosphorylation into the cell. We also showed that the specific recognition of flagellin by rice is regulated by the glycans at^<178> Ser and^<183> Ser in flagellin prevent epitope recognition in rice.
