PR5 — Brachypodium distachyon

Summary

BdPR5 (BRADI_4G03285V3) on Brachypodium distachyon chromosome 4 encodes a thaumatin-like protein belonging to the osmotin/thaumatin-like superfamily, with serine-type endopeptidase inhibitor activity and mRNA binding. This gene is associated with regulation of anthocyanin anabolism, killing of cells of other organism, response to cadmium, response to virus, response to UV-B, response to bacteria, response to ethylene, defence response to fungi, and cell death. It is linked to defense response, systemic acquired resistance, disease resistance, salicylic acid defense response, insect resistance, pathogen response, pathogen defense response, fungal resistance, salt tolerance, resistance to Verticillium dahliae, UV-B stress response, stress response, resistance to Pseudomonas syringae, and disease resistance to Pseudomonas syringae pv. tomato. The protein localises to the apoplast, plant-type cell wall, plant-type vacuole, plasmodesma, secretory vesicle, extracellular region, mitochondria, and membrane. Studies of related genes in other species connect the family to grain yield, seed size, drought tolerance, nitrogen sensitivity, plant height, root morphology, germination rate, and heterosis.
