AFT1 — Oryza sativa Indica Group

Summary

BGIOSGA016551 (AFT1, also known as OiGF14B, OiGF14C, and GF14-KAPPA) on chromosome 4 of Indica rice encodes a 14-3-3 domain-containing protein. The product has been annotated with a wide range of molecular functions including calcium-activated potassium channel activity, quercetin 3-O-methyltransferase activity, and phosphatidylethanolamine binding. In rice, AFT1 is associated with drought tolerance, salt stress tolerance, blast resistance, brassinosteroid signaling, root elongation, and biomass. The gene is linked to responses to brassinosteroid and nitrogen levels, as well as to flavonol biosynthesis and sucrose breakdown. It has been connected to traits including spikelet floret size, crown root number, leaf area, and brassinosteroid content. Studies of related genes in other species link these proteins to stress response, nitrogen use efficiency, and phototropism.
