Summary Rice diseases caused by multiple pathogen species are a major obstacle to achieving optimal yield. Using host pathogen species‐non‐specific broad‐spectrum resistance ( BSR ) for rice improvement is an efficient way to control diseases. Recent advances in rice genomics and improved understanding of the mechanisms of rice‐pathogen interactions have shown that using a single gene to improve rice BSR to multiple pathogen species is technically possible and the necessary resources exist. A variety of rice genes, including major disease resistance genes and defense‐responsive genes, which function in pattern‐triggered immunity signaling, effector‐triggered immunity signaling or quantitative resistance, can mediate BSR to two or more pathogen species independently. These genes encode diverse proteins and function differently in promoting disease resistance, thus providing a relatively broad choice for different breeding programs. This updated knowledge will facilitate rice improvement with pathogen species‐non‐specific BSR via gene marker‐assisted selection or biotechnological approaches.
