GOLS — Cucumis sativus

Summary

CsGOLS (CSA_3G680120) on cucumber chromosome 3 encodes an inositol 3-alpha-galactosyltransferase (EC 2.4.1.123) with transglycosidase activity, belonging to the glycosyltransferase family 8. This enzyme is associated with raffinose family oligosaccharide biosynthesis, galactose metabolism, carbohydrate storage, and phloem loading. It is associated with cellular responses to desiccation, cold, heat, high light intensity, oxidative stress, and abscisic acid, as well as defense response and induced systemic resistance. The gene is associated with traits including nematode damage response, sucrose content, photosynthetic rate, low temperature stress response, disease tolerance, and salt tolerance. Phenotypic associations include cold response, drought tolerance, salt tolerance, fruit ripening, chlorophyll accumulation, and heat stress tolerance. Studies of related genes in other species link the family to cold, salt, and oxidative stress tolerance, galactinol and stachyose biosynthesis, and grain yield.
