GOLS — Cucumis sativus

Summary

CsGOLS (CSA_1G181330) encodes an inositol 3-alpha-galactosyltransferase (EC 2.4.1.123) with transglycosidase activity, belonging to the glycosyltransferase family 8. The gene is associated with raffinose family oligosaccharide biosynthesis, galactose metabolism, and carbohydrate storage. It is linked to cellular responses to desiccation, cold, heat, high light intensity, oxidative stress, and abscisic acid, as well as phloem loading, raffinose transport, and induced systemic resistance. The encoded protein localizes to the Golgi complex, cytoplasm, and nucleus. CsGOLS is associated with sucrose content, photosynthetic rate, and traits including cold, drought, salt, and heat stress tolerance, fruit ripening, and chlorophyll accumulation. Studies of related genes in other species connect the family to grain yield, seed weight, seed longevity, disease resistance, and abiotic stress tolerance.
