RS4 — Cucumis sativus

Summary

CSA_7G407800 (RS4, STS) in cucumber (Cucumis sativus) on chromosome 7 encodes a stachyose synthase, a member of the glycosyl hydrolase 36 family with galactinol-raffinose galactosyltransferase and raffinose synthase activities. The gene is associated with stachyose and raffinose biosynthesis, oligosaccharide and inositol metabolism, sucrose transport and metabolism, phloem transport, gibberellin biosynthesis, fruit development, and cell wall organization. It has been linked to fruit yield, fruit dry weight, fruit length and size, sugar content, photosynthetic rate, transpiration rate, drought tolerance, low temperature stress tolerance, nematode damage response, starch mobilization, carbohydrate distribution, phloem loading, source-sink regulation, and carbon partitioning. Studies of related genes in other species connect the family to seed germination, stachyose biosynthesis, seed longevity, sucrose content, seed size, and cytokinin content.
