ABSTRACT=<p>The brassinosteroid-SIGNALING KINASE (BSK) belongs to the receptor-like cytoplasmic kinase XII subgroup. BSK1 regulates development and immunity in <italic>Arabidopsis</italic>. However, the function of rice (<italic>Oryza sativa</italic>) BSK1 is largely unknown. Here, we report that the expression level of <italic>OsBSK1-2</italic> is induced after a chitin or fagellin22 (flg22) treatment. Silencing <italic>OsBSK1-2</italic> in rice results in compromised responses to chitin- or flg22-triggered immunity and resistance to <italic>Magnaporthe oryzae</italic>, 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.</p>
