CAGOLS1 — Cicer arietinum

Summary

CAGOLS1 (GOLS1) on chickpea chromosome 3 encodes an inositol 3-alpha-galactosyltransferase (EC 2.4.1.123) with a glycosyltransferase domain, conferring metal-binding activity. This gene is associated with raffinose family oligosaccharide biosynthesis, galactose metabolism, and raffinose transport, as well as carbohydrate storage. It is linked to responses to desiccation, cold, heat, high light intensity, oxidative stress, salinity, and abscisic acid, along with seed development, circadian rhythm, and regulation of gene expression. The encoded product localizes to the cytoplasm. CAGOLS1 is associated with heat stress tolerance, oxidative stress tolerance, and abiotic stress response. Related genes in other species connect the family to galactinol biosynthesis, drought tolerance, seed longevity, and salt and heat stress response.
