PR5 — Oryza sativa Indica Group

Summary

BGIOSGA031159 (PR5, OiPR5) on indica rice chromosome 9 encodes a thaumatin-like protein with glucan endo-1,3-beta-D-glucosidase activity and IgE binding capacity. This gene is associated with defence responses to fungi, the killing of cells of other organisms, and responses to abscisic acid, as well as with signal transduction, the TCA cycle, and phenylpropanoid anabolism. The product localises to the apoplast and extracellular space. PR5 has also been linked to grain yield. Related genes in other species connect the family to glucan endo-1,3-beta-glucosidase activity (EC 3.2.1.39).
