MST6 — Cucumis sativus

Summary

CSA_2G094400 (MST6) on cucumber chromosome 2 encodes a hexose transporter belonging to the MFS_STP/MST-like plant family, with monosaccharide transmembrane transporter and symporter activities. The gene is associated with stachyose metabolism, phloem unloading, nectar secretion, malate and amino acid metabolism, and multiple reproductive processes including pollen tube development, pollen germination, pollen maturation, syngamy, and sexual reproduction. It is also linked to fruit and seed development, tube development, secretion, virus-induced PTGS, and homeostasis. The encoded protein localizes to the membrane and plasmalemma. Associations with germination ratio, fruit size, sugar content, and seed size have been noted.
