11N3 — Oryza sativa Indica Group

Summary

BGIOSGA037364 (Xa25, also known as 11N3, SWEET14, and SWEET15) encodes a SWEET family protein with gibberellin transmembrane transporter activity, sucrose permease activity, sugar transmembrane transporter activity, and protein binding capability. In indica rice, this gene is associated with bacterial blight resistance, grain filling, yield, plant height, and development. It has been linked to pollen development, fertility, embryo development, and flowering, as well as responses to abiotic stresses including drought, salt, and abscisic acid. The protein localizes to the plasma membrane, Golgi membrane, and trans-Golgi network membrane. Associations extend to leaf senescence, anther dehiscence, seed growth and maturation, copper ion transport, cell wall callose deposition, and responses to salicylic acid and long-day conditions. Studies of related genes in other species link the SWEET family to phloem loading, sucrose transport, seed filling, and gibberellin transport.
