11N3 — Oryza sativa Indica Group

Summary

BGIOSGA010744 (Oi11N3) on chromosome 3 of indica rice encodes a SWEET family protein with sugar transmembrane transporter activity, gibberellin transmembrane transporter activity, and sucrose permease activity. The gene is associated with grain filling, grain weight, endosperm, yield, plant height, and bacterial blight resistance in rice. It has been linked to pollen development, fertility, flowering, embryo development, leaf senescence, and responses to abiotic stresses including drought, salt, and abscisic acid. Associations also include panicle length, photosynthetic rate, starch mobilization, nitrogen remobilization, and carbon allocation. The protein localizes to the plasma membrane, Golgi membrane, and trans-Golgi network membrane. Studies of related genes in other species link the SWEET family to phloem loading, sucrose transport, seed filling, pollen germination, and gibberellin transport.
