We identify the rice cystathionine \u03b2-synthase domain\u2013containing protein OsCBSX3 as a direct intracellular target of NlSP2. Genetic analyses establish OsCBSX3 as a positive regulator of BPH resistance and an essential component of NlSP2-triggered immunity. NlSP2 binding promotes OsCBSX3 nuclear accumulation. In the nucleus, OsCBSX3 interacts with the NAC transcription factor SNAC3; NlSP2 enhances this interaction and potentiates SNAC3-mediated transcriptional activation of defense genes.
