AFT1 — Oryza sativa Indica Group

Summary

BGIOSGA008496 (AFT1, also known as OiGF14-KAPPA, GF14C, and GF14B) on chromosome 2 of Indica rice encodes a 14-3-3 domain-containing protein. The gene product is associated with a wide array of molecular functions including calcium-activated potassium channel activity, quercetin 3-O-methyltransferase activity, and phosphatidylethanolamine binding. In rice, AFT1 has been linked to drought tolerance, salt stress tolerance, root elongation, blast resistance, brassinosteroid signaling, and plant development. It is also associated with responses to gravity, nitrogen levels, and brassinosteroid stimulus, as well as flavonol biosynthesis and anthocyanin metabolism. The protein has been localized to the nuclear microtubule, vacuolar membrane, and peroxisome membrane. Studies of related genes in other species connect the family to disease resistance, seed germination under salinity stress, and nitrogen use efficiency.
