PR5 — Oryza sativa Indica Group

Summary

BGIOSGA024205 (PR5, also known as TOND1) in Indica rice encodes a thaumatin-like protein belonging to the osmotin/thaumatin-like superfamily, with mRNA binding activity. This gene is associated with grain yield, nitrogen deficiency tolerance, and overall yield in rice. It is linked to defence responses against fungi, bacteria, and viruses, as well as responses to cadmium, UV-B, and ethylene. The encoded protein localises to the apoplast, plant-type cell wall, vacuole, plasmodesmata, secretory vesicles, and mitochondria. Additionally, associations with systemic acquired resistance, disease resistance, insect resistance, salt tolerance, and resistance to Verticillium dahliae and Pseudomonas syringae have been reported. Related genes in other species are linked to induced systemic resistance, pathogen resistance, herbivore defence, and seed germination under salt stress.
