SUT — Cucumis melo

Summary

MELO3C011115.2 (SUT, SUT4) on melon chromosome 4 encodes a protein with a sucrose symporter domain and major facilitator superfamily (MFS) domain, with annotated activities including sucrose:proton symporter activity, maltose:proton symporter activity, and arbutin and salicin transmembrane transporter activity. The gene is associated with phloem sucrose loading, maltose transport, and carbohydrate membrane transport. It is linked to grain yield, unfilled grain number, sucrose and sugar content, photosynthetic rate, respiration rate, days to flowering, seed dormancy, root morphology, plant stress response, and abiotic stress response. Additional associations include phenolic compound content, lignin biosynthesis, jasmonic acid content, auxin sensitivity, trichome morphology, stomatal closure, and cell cycle traits. The encoded protein localises to the tonoplast, chloroplast outer membrane, pollen tube, and cis-Golgi network.
