PR5 — Oryza sativa Indica Group

Summary

BGIOSGA023512 (PR5, also known as OiPR5, TOND1, and OSML) on chromosome 6 of Indica rice encodes a thaumatin-like protein with glucan endo-1,3-beta-D-glucosidase activity, IgE binding, and mRNA binding. This gene is associated with grain yield, nitrogen deficiency tolerance, and breeding traits, as well as responses to abscisic acid, ethylene, salicylate, UV-B, cadmium, bacteria, fungi, viruses, and salinity. It is associated with defence responses, systemic acquired resistance, disease resistance, insect resistance, and salt tolerance. The protein localises to the apoplast, plant-type cell wall, vacuole, plasmodesma, secretory vesicle, membrane, mitochondria, and extracellular space. Studies of related genes in other species connect the family to induced systemic resistance, pathogen resistance, herbivore defence, and seed germination under salt stress.
