AS11 — Arabidopsis thaliana

Summary

AT2G19450 (AS11, also known as RDS1 or DGAT1) on Arabidopsis thaliana chromosome 2 encodes a diacylglycerol O-acyltransferase (EC 2.3.1.20) of the MBOAT family. The gene is associated with oil content, seed oil accumulation, seed weight, and triacylglycerol content in seeds, as well as leaf biomass, freezing tolerance, and fatty acid accumulation. It has been linked to seed yield, harvest index, seed viability, seed length, leaf size, plant height, starch and sugar content, and responses to high and low temperature stress. The product localizes to the endoplasmic reticulum membrane, adiposomes, and chloroplast membranes, and is associated with neutral lipid anabolism, glycerolipid biosynthesis, and regulation of embryonic development. Related genes in other species are linked to triacylglycerol accumulation and fruit development.
