GOLS1 — Sorghum bicolor
Summary
SORBI_3002G423600 (SbGOLS1) on sorghum chromosome 2 encodes a galactinol synthase (EC 2.4.1.123) with inositol 3-alpha-galactosyltransferase activity, belonging to the glycosyltransferase family 8. The gene is associated with raffinose family oligosaccharide biosynthesis, raffinose anabolism, inositol anabolism, and galactose metabolism. It is linked to cellular responses to desiccation, cold, heat, high light intensity, oxidative stress, and salinity, as well as to carbohydrate storage, phloem transport, and sucrose transport. The encoded protein localises to the Golgi complex, cytoplasm, and nucleus. SbGOLS1 is associated with abiotic stress response and heat stress tolerance. Studies of related genes in other species connect the family to drought and salt tolerance, cold tolerance and galactinol biosynthesis, disease resistance, and arsenic tolerance, as well as to grain yield, seed longevity, and leaf blast disease response.
