GT3 — Cucumis sativus

Summary

CsGT3 (CSA_4G618500) encodes a UDP-glucosyltransferase in cucumber (Cucumis sativus) on chromosome 4. The enzyme exhibits multiple glucosyltransferase activities, including quercetin 3'-O-, 4'-O-, 7-O-, and 3-O-glucosyltransferase, anthocyanidin 3-O-glucosyltransferase, flavonol 3-O-glucosyltransferase, and abscisic acid glucosyltransferase activities. CsGT3 is associated with abscisic acid breakdown and metabolism, chlorophyll metabolism and breakdown, carotenoid, anthocyanin, flavonoid, and terpenoid anabolism, regulation of organ growth, drought recovery, osmotic response, and downregulation of systemic acquired resistance. The gene is linked to fruit shape, chlorophyll content, and proline content traits. Studies of related genes in other species connect the family to abscisic acid homeostasis, drought tolerance, seed germination, and stress tolerance.
