AS11 — Camelina sativa

Summary

CsAS11 (CSA15G084220) on Camelina sativa chromosome 15 encodes a diacylglycerol O-acyltransferase, a member of the MBOAT family. The gene is associated with fatty acid and triglyceride anabolism, glycerol metabolism, and the TCA cycle, and is linked to responses to abscisic acid, cold, glucose, and salinity. It is associated with seed development, germination, size, mass, and harvest index, as well as triacylglycerol accumulation in seeds, pollen, and vegetative tissues, pollen development and tube growth, leaf senescence, CO2 assimilation, osmotic stress tolerance, and temperature tolerance. The encoded protein localizes to the endoplasmic reticulum membrane, chloroplast envelope, nucleus, and adiposomes. Studies of related genes in other species link the family to seed oil content, fatty acid composition, freezing tolerance, and transposable element excision.
