RS1 — Brassica oleracea

Summary

BoRS1 (RS1, SIP1) on cabbage chromosome 3 encodes a protein with glycosyl hydrolase 36 and aldolase_TIM domains, and has been annotated with galactinol-raffinose galactosyltransferase and raffinose synthase activities. The gene is associated with stachyose and oligosaccharide anabolism, as well as detoxification, and its product localises to the cytoplasm. BoRS1 is linked to leaf chlorophyll content and chlorophyll content traits. Studies of related genes in other species connect the family to sugar content, starch content, salt response, and phenotypes including late flowering, developmental retardation, and reduced fertility.
