油菜素类固醇信号激酶（BSK）属于受体样细胞质激酶XII亚群。BSK1调控拟南芥的发育和免疫。然而，水稻BSK1的功能在很大程度上是未知的。在这里，我们报道了OsBSK1-2在几丁质或fagellin22 （flg22）处理后的表达水平被诱导。在水稻中沉默OsBSK1-2会导致对几丁质或flg22触发的免疫反应和对稻瘟病菌的抗性降低，但不会改变植物的结构，也不会降低植物对油菜素内酯信号的反应。我们的研究表明OsBSK1-2在水稻植株免疫中起着重要的调节作用。
The brassinosteroid-SIGNALING KINASE (BSK) belongs to the receptor-like cytoplasmic kinase XII subgroup. BSK1 regulates development and immunity in Arabidopsis. However, the function of rice (Oryza sativa) BSK1 is largely unknown. Here, we report that the expression level of OsBSK1-2 is induced after a chitin or fagellin22 (flg22) treatment. Silencing OsBSK1-2 in rice results in compromised responses to chitin- or flg22-triggered immunity and resistance to Magnaporthe oryzae, 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.
