TMT2 — Beta vulgaris subsp. vulgaris

Summary

BvTMT2 (BVRB_9G215730) on sugar beet chromosome 9 encodes a protein with monosaccharide transmembrane transporter activity, symporter activity, and nucleoside transmembrane transporter activity, and belongs to the myo-inositol transporter family within the major facilitator superfamily. The gene is associated with responses to fructose, glucose, sucrose, salt, and cold, as well as with NO storage and homeostasis. It is linked to vacuolar sugar compartmentation, sugar transport, and substantial reductions in leaf glucose and fructose content. Associations also include seed weight, photosynthetic rate, seedling development, and seed germination. Studies of related genes in other species connect the family to fructose, glucose, sucrose, and starch content, as well as biomass yield and seedling growth traits.
