AS11 — Sorghum bicolor

Summary

SbAS11 (SORBI_3010G170000) on sorghum chromosome 10 encodes a diacylglycerol O-acyltransferase, a member of the MBOAT family with a diacylglycerol acyltransferase domain, and exhibits diacylglycerol O-acyltransferase activity and protein binding. The gene is associated with triacylglycerol and fatty acid biosynthesis, seed storage lipid accumulation, seed development and germination, pollen development and lipid content, leaf senescence, CO2 assimilation, and responses to abscisic acid, cold, glucose, and salinity. It is linked to regulation of embryonic development, seed germination, and triglyceride and carbohydrate metabolism. The encoded protein localizes to the adiposome, chloroplast envelope, ER membrane, and nucleus. Related genes in other species are associated with seed oil content, seed weight, freezing tolerance, and triacylglycerol accumulation in vegetative tissues.
