AKR — Oryza sativa Indica Group

Summary

BGIOSGA001198 (symbol AKR, OiAKR) on chromosome 1 of Indica rice encodes a NADP-dependent oxidoreductase domain-containing protein belonging to the aldo-keto reductase family, with NADP-aldehyde reductase and redox activities. It is associated with detoxification, alkaloid metabolism, and auxin signaling, and is linked to sucrose response. The protein localizes to the chloroplast envelope, cytosol, plasmalemma, cytoplasm, and nucleus. Related genes in other species are linked to heat and drought tolerance, seed germination, callus induction, and root morphology traits, though these associations are not yet established for this rice gene.
