PR5 — Brachypodium distachyon

Summary

BdPR5 (BRADI_3G40596V3) on chromosome 3 of Brachypodium distachyon encodes a thaumatin-like protein belonging to the osmotin/thaumatin-like superfamily, with glucan endo-1,3-beta-D-glucosidase activity, IgE binding, and mRNA binding. The gene is associated with defence responses to fungi, bacteria, and viruses, as well as responses to UV-B, ethylene, abscisic acid, and cadmium. It is linked to cell death, regulation of anthocyanin anabolism, and killing of cells of other organisms. The protein localises to the apoplast, plant-type cell wall, secretory vesicle, plant-type vacuole, plasmodesma, mitochondria, and membrane. Associations include systemic acquired resistance, disease resistance, insect resistance, salt tolerance, and resistance to Verticillium dahliae and Pseudomonas syringae. Studies of related genes in other species link the family to grain yield, drought tolerance, seed size, and nitrogen sensitivity.
