SUT1 — Glycine max

Summary

GmSUT1 (GLYMA_10G217900V4) on soybean chromosome 10 encodes a sucrose:proton symporter belonging to the sucrose symporter plant family and the major facilitator superfamily, with additional annotated activities for arbutin, salicin, and maltose:proton symport. The gene is associated with phloem loading, sucrose transport and metabolism, maltose transport, TCA cycle, nitrogen fixation, triglyceride mobilization, chlorophyll metabolism, regulation of photosynthesis, DNA replication, histogenesis, cotyledon development, pollen germination, and seed germination. It is linked to traits including seed weight, plant height, stem diameter, net photosynthetic rate, chlorophyll content, sugar and starch content, protein content, abscisic acid content, and hydrogen peroxide content. The protein localizes to the membrane, plasmalemma, tonoplast, vacuole, and cis-Golgi network. Studies of related genes in other species link the family to leaf relative water content.
