Japanese researchers discover how family of genes regulate immune responses in cereals

In Japan, the mechanism of plant defense mediated by the non-expressor of pathogenesis-related (NPR) genes in monocots (plants having a single embryonic leaf) is not well-documented. Now, scientists from Tokyo University of Science have discovered how the NPR family of genes regulate immune responses in the model monocot Brachypodium distachyon. These findings provide a blueprint for plants’ defense systems and might contribute to more research towards resilient crop species, boosting pesticide-free cereal crop cultivation. Their study, which was published in The Plant Journal, explains how NPR genes in B. distachyon regulate TGA-promoted transcription of defense-responsive genes.
