SUT — Beta vulgaris subsp. vulgaris

Summary

BvSUT (BVRB_6G154300) on sugar beet chromosome 6 encodes a member of the major facilitator superfamily (MFS) with sucrose:proton symporter activity, and is also annotated for maltose, arbutin, salicin and biotin transmembrane transporter activities. The gene is associated with phloem sucrose loading, maltose transport, and carbohydrate membrane transport. It has been linked to numerous agronomically important traits including sucrose content, grain yield, unfilled grain number, photosynthetic rate, respiration rate, root thickness, seed dormancy, days to flowering, and responses to abiotic stress and oxidative stress. Additional associations include phenolic compound content, jasmonic acid content, auxin sensitivity, cell elongation, trichome morphology, and stomatal complex closure time. The encoded protein localises to the tonoplast, chloroplast outer membrane, and cis-Golgi network.
