AS11 — Brassica napus

Summary

BnAS11 (DARMORV10_C07P02710.1) on chromosome C07 encodes a diacylglycerol O-acyltransferase, a member of the MBOAT family with a diacylglycerol acyltransferase domain, and has diacylglycerol O-acyltransferase activity and protein binding. This gene is associated with neutral lipid anabolism, the Kennedy pathway, triglyceride anabolism, lipogenesis, fatty acid elongation, lipid homeostasis, and responses to glucose and stress. It is linked to seed protein content, seed size, cellulose content, and numerous seed and pollen traits including triacylglycerol accumulation, fatty acid composition, seed mass, germination, osmotic stress tolerance, and temperature tolerance. The product localizes to the ER membrane, adiposome, chloroplast envelope, and nucleus. Studies of related genes in other species link the family to seed oil content, fatty acid accumulation, freezing tolerance, and leaf biomass.
