PR5 — Oryza sativa Indica Group

Summary

BGIOSGA011165 (PR5, also known as TOND1) on indica rice chromosome 3 encodes a thaumatin-like protein belonging to the osmotin/thaumatin-like superfamily and is annotated with glucan endo-1,3-beta-D-glucosidase activity, IgE binding, and mRNA binding. The gene is associated with grain yield, nitrogen deficiency tolerance, and breeding traits, as well as defence responses to fungi, bacteria, and viruses, and responses to abscisic acid, ethylene, UV-B, and cadmium. It is linked to regulation of anthocyanin and phenylpropanoid anabolism, the TCA cycle, and signal transduction. The product localises to the apoplast, plant-type cell wall, vacuole, plasmodesmata, secretory vesicles, mitochondria, and membrane. Associations also include systemic acquired resistance, disease resistance, insect resistance, salt tolerance, and resistance to Verticillium dahliae and Pseudomonas syringae. Related genes in other species link the family to induced systemic resistance, pathogen resistance, and herbivore defence.
