RFS — Cucumis sativus

Summary

CsRFS (CSA_3G838720) on cucumber chromosome 3 encodes a glycosyl hydrolase 36 family protein with raffinose synthase activity (EC 2.4.1.82) and galactinol-raffinose galactosyltransferase activity. The gene is associated with raffinose family oligosaccharide biosynthesis, stachyose and raffinose anabolism, phloem loading, and sucrose transport and metabolism. It has been linked to sex determination, induced systemic resistance, calcium signaling, and RNA metabolism. Associations include raffinose and abscisic acid content, fruit length, photosynthetic and transpiration rates, chlorophyll content, low temperature stress response, and drought tolerance. Studies of related genes in other species link the family to desiccation tolerance, seed germination, and raffinose accumulation.
