PR5 — Brachypodium distachyon

Summary

BdPR5 (BRADI_4G03280V3) on chromosome 4 of Brachypodium distachyon encodes a thaumatin-like protein with predicted glycosidase activity and mRNA binding. This gene is associated with defence responses, including response to bacteria, fungi, viruses, and cell death, as well as regulation of anthocyanin metabolism, response to cadmium, UV-B, and ethylene. The protein localises to the apoplast, cell wall, vacuole, plasmodesma, mitochondria, and secretory vesicles. BdPR5 is associated with systemic acquired resistance, disease resistance, insect resistance, salt tolerance, and resistance to Verticillium dahliae and Pseudomonas syringae. Studies of related genes in other species connect the family to grain yield, seed size, drought tolerance, nitrogen sensitivity, plant height, and root morphology traits.
