PR5 — Brachypodium distachyon

Summary

BdPR5 (BRADI_1G33540V3) on chromosome 1 of Brachypodium distachyon encodes a thaumatin-like protein with glucan endo-1,3-beta-D-glucosidase activity, a member of the osmotin/thaumatin-like superfamily. The gene is associated with responses to viruses, bacteria, UV-B, ethylene, abscisic acid, cadmium, and arachidonate, as well as with regulation of anthocyanin anabolism and cell death. Its product localises to the apoplast, plant-type cell wall, vacuole, plasmodesmata, secretory vesicles, mitochondria, and membrane. BdPR5 is linked to defence responses, systemic acquired resistance, disease resistance, salicylic acid-mediated defence, insect resistance, fungal resistance, salt tolerance, and resistance to Verticillium dahliae and Pseudomonas syringae. Related genes in other species are linked to grain yield, nitrogen sensitivity, drought tolerance, seed germination, and root morphology.
