SUT — Beta vulgaris subsp. vulgaris

Summary

BvSUT (BVRB_1G000740) on sugar beet chromosome 1 encodes a protein with sucrose:proton symporter activity, belonging to the major facilitator superfamily. The gene is associated with phloem sucrose loading, maltose transport, and carbohydrate membrane transport. It has been linked to grain yield, sucrose content, photosynthetic rate, respiration rate, and abiotic stress response traits. Associations include seed dormancy, root morphology, days to flowering, and plant growth and development. The gene is connected to triacylglycerol accumulation, phloem unloading, drought tolerance, and stomatal closure. Studies of related genes in other species link the family to phloem transport, carbon partitioning, tuberization, grain size, yield, and abiotic stress tolerance.
