AS11 — Beta vulgaris subsp. vulgaris

Summary

BvAS11 (BVRB_8G199240) on sugar beet chromosome Bvchr8_un.sca001 encodes a diacylglycerol O-acyltransferase, a member of the MBOAT family with diacylglycerol acyltransferase activity. The gene is associated with triglyceride anabolism, lipid homeostasis, glycerol and carbohydrate metabolism, and responses to abscisic acid, cold, salinity, and glucose. It is linked to regulation of seed germination and embryonic development, DNA damage response and repair, and localises to the ER membrane, chloroplast envelope, nucleus, and adiposome. Associations include seed mass, fatty acid composition, triacylglycerol accumulation in vegetative tissues and pollen, CO₂ assimilation rate, leaf senescence, stamen and carpel development, floral determinacy, fruit ripening, osmotic stress tolerance, and temperature tolerance. Studies of related genes in other species link the family to seed oil content, freezing tolerance, and transposable element excision.
