MTN3 — Oryza sativa Japonica
Summary
OS08G0535200 (MTN3, also known as Xa13, OsSWEET11, OsSWEET14, and other synonyms) on rice chromosome 8 encodes a SWEET family protein with sugar transmembrane transporter activity and gibberellin transmembrane transporter activity. It is associated with grain filling, grain size, grain weight, yield, and starch content, as well as bacterial blight resistance and susceptibility. The gene has been connected to pollen development, fertility, embryo development, and seed maturation. It is linked to responses to abiotic stresses including drought and salt, and to abscisic acid and salicylic acid signaling. Localization evidence places the product at the plasma membrane, Golgi membrane, and trans-Golgi network membrane. Studies of related genes in other species link the family to phloem loading, seed filling, and sucrose transport.
