11N3 — Oryza sativa Japonica

Summary

Os11g0508600 (11N3) encodes a SWEET family protein with SWEET_rpt domains and exhibits gibberellin transmembrane transporter, sucrose permease, and sugar transmembrane transporter activities. In rice, this gene is associated with grain filling, grain size, yield, height, and resistance to bacterial blight (Xoo), as well as pollen development, fertility, flowering, and embryo development. It is linked to responses to abiotic stresses including drought and salt, and to abscisic acid and salicylic acid signaling. The protein localizes to the plasma membrane, Golgi, and trans-Golgi network membranes. Associations also connect it to grain plumpness, starch content, seed size, photosynthetic rate, days to heading, and nitrogen use efficiency. Studies of related genes in other species link the SWEET family to phloem loading, sucrose transport, seed filling, and gibberellin transport.
