PR5 — Oryza sativa Indica Group

Summary

BGIOSGA038384 (symbol PR5, also known as OiPR5) in Indica rice encodes a thaumatin-like protein belonging to the osmotin/thaumatin-like superfamily and exhibits glucan endo-1,3-beta-D-glucosidase activity and IgE binding. This gene is associated with defense responses, including defense response to fungi and killing of cells of other organisms, as well as response to abscisic acid, signal transduction, the TCA cycle, and phenylpropanoid anabolism. The encoded protein localizes to the apoplast and extracellular space. PR5 has also been linked to grain yield. Studies of related genes in other species connect the family to glucan endo-1,3-beta-glucosidase activity (EC 3.2.1.39).
