TMT2 — Beta vulgaris subsp. vulgaris
Summary
BvTMT2 (BVRB_5G115690) on sugar beet chromosome 5 encodes a member of the Myo-inositol Transporter family within the major facilitator superfamily (MFS), possessing nucleoside and monosaccharide transmembrane symporter activity. The protein localises to the tonoplast, plant-type vacuole, Golgi complex, and plasma membrane. BvTMT2 is associated with responses to fructose, glucose, sucrose, salt, and cold, as well as with NO storage, homeostasis, and thirst response. It has been linked to seed weight, photosynthetic rate, sugar homeostasis, seedling development, seed germination, vacuolar sugar compartmentation, and substantial reductions in leaf glucose and fructose content. Studies of related genes in other species connect the family to fructose, glucose, sucrose, and starch content, biomass yield, and seedling and seed growth traits.
