AS11 — Brassica napus

Summary

BnAS11 (DARMORV10_A07P01320.1) on chromosome A07 of oilseed rape encodes a diacylglycerol O-acyltransferase, a member of the MBOAT family. The gene is associated with neutral lipid anabolism, the Kennedy pathway, lipogenesis, and triglyceride anabolism, as well as with lipid homeostasis, fatty acid elongation, and responses to glucose and stress. It has been linked to seed protein content, seed size, cellulose content, and numerous seed oil-related traits including triacylglycerol accumulation, fatty acid composition, seed mass, and germination. Associations also extend to pollen development, leaf senescence, CO2 assimilation, osmotic stress tolerance, and temperature tolerance. The protein localizes to the ER membrane, chloroplast envelope, adiposome, and nucleus. Studies of related genes in other species link the family to seed oil content, freezing tolerance, and lipid accumulation.
