In both plant and animal innate immune responses, surveillance of pathogen infection is mediated by membrane-associated receptors and intracellular nucleotide-binding domain & leucine-rich repeat receptors (NLRs). Homeostasis of NLRs is under tight multilayered regulation to avoid over-accumulation or over-activation, which often leads to autoimmune responses that cause detrimental effects on growth and development. How NLRs are regulated epigenetically at the chromatin level remains unclear. Here, we report that SWP73A, an orthologue of the mammalian switch/sucrose nonfermentable (SWI/SNF) chromatin remodeling protein BAF60, suppresses the expression of NLRs either directly by binding to the NLR promoters or indirectly by affecting the alternative splicing of some NLRs through the suppression of Cell Division Cycle 5 (CDC5), a key regulator of RNA splicing. Upon infection, bacteria-induced small RNAs silence SWP73A to activate a group of NLRs and trigger robust immune responses. SWP73A may function as a H3K9me2 reader to enhance transcription suppression. NLR-mediated immunity is under precise control to avoid autoimmunity. Huang et al. report a new regulation mechanism in which the chromatin remodeling protein SWP73A suppresses NLRs’ expression directly by transcriptional suppression or indirectly by modulating NLR’s alternative splicing. SWP73A is silenced by bacteria-induced small RNAs to activate NLR expression.
