RFS — Beta vulgaris subsp. vulgaris

Summary

BvRFS (BVRB_5G117710) on sugar beet chromosome 5 encodes a protein with raffinose synthase activity and galactinol-raffinose galactosyltransferase activity, belonging to the glycosyl hydrolase 36 family. The gene is associated with raffinose family oligosaccharide biosynthesis, as well as stachyose, sucrose, and mannitol anabolism. It is linked to response to oxidative stress, thirst, and homologous recombination, and localises to the cytoplasm. Associations include photosynthetic rate, abiotic stress tolerance, and cytoplasmic male sterility. Studies of related genes in other species connect the family to seed germination, desiccation tolerance, and raffinose accumulation, while sequence similarity links extend to traits such as drought tolerance, leaf water potential, chlorophyll content, plant height, seed viability, and responses to low temperature and abiotic stress.
