PR1 — Oryza sativa Indica Group

Summary

BGIOSGA025089, designated OiPR1 on Indica rice chromosome 7, encodes a CAP domain-containing protein of the SCP family, also known as a V5 allergen-like or pathogenesis-related protein PR-1 type. The gene is associated with immune response, defense response to other organisms, and cell death, as well as biological regulation and signal transduction. It has been linked to secondary metabolite biosynthesis, including diterpenoid and alkaloid anabolism. The product localises to the extracellular region and the vacuole. Studies of related genes in other species connect this family to defense signaling and stress responses, though such roles are not yet established for this specific rice gene.
