The brassinosteroid-SIGNALING KINASE (BSK) belongs to the receptor-like cytoplasmic kinase XII subgroup. BSK1 regulates development and immunity in . However, the function of rice () BSK1 is largely unknown. Here, we report that the expression level of is induced after a chitin or fagellin22 (flg22) treatment. Silencing in rice results in compromised responses to chitin- or flg22-triggered immunity and resistance to , but does not alter the plant's architecture nor reduce plant responses to brassinosteroid signaling. Our study reveals that OsBSK1-2 functions as a major regulator in rice plant immunity.
油菜素类固醇信号激酶（BSK）属于类受体细胞质激酶XII亚组。BSK1调节植物的发育和免疫。然而，水稻BSK1的功能在很大程度上尚不清楚。在此，我们报道水稻中OsBSK1-2的表达水平在几丁质或鞭毛蛋白22（flg22）处理后被诱导。在水稻中沉默OsBSK1-2会导致对几丁质或flg22触发的免疫反应受损以及对稻瘟病菌的抗性降低，但不会改变植物的形态结构，也不会降低植物对油菜素类固醇信号的反应。我们的研究表明，OsBSK1-2在水稻植株免疫中起主要调节作用。
