RGA1 — Oryza sativa Indica Group

Summary

BGIOSGA004355 (RGA1, also known as OiHSP70) on chromosome 1 of Indica rice encodes a disease resistance N-terminal domain-containing protein with nucleotide, ADP and ATP binding activities. This gene is associated with auxin transport and signaling, amino acid membrane transport, antiviral and defense responses, signal transduction, stress response, and seed germination. It has been linked to numerous agronomic traits including grain yield, grain size, spikelet fertility, panicle length, spikelet number, plant height, leaf size, root length, relative root length, photosynthetic rate, and heat tolerance. Related genes in other species connect the family to grain shape, grain width, grain length, stem rust, stripe rust, and net photosynthetic rate.
