AS11 — Camelina sativa

Summary

CsAS11 (CSA19G056370) on Camelina sativa chromosome 19 encodes a diacylglycerol O-acyltransferase, a member of the MBOAT family. This gene is associated with triacylglycerol assembly and accumulation, seed storage lipid biosynthesis, fatty acid content and composition, seed size, seed mass, and harvest index. It is linked to pollen development, pollen tube growth, and total lipid content in pollen, as well as to seed germination, germination rate, and regulation of seed germination. Additional associations include responses to abscisic acid, cold, salinity, and glucose, leaf senescence, CO2 assimilation rate, osmotic stress tolerance, temperature tolerance, and tocochromanol accumulation. The gene is linked to adiposome organization and localizes to the endoplasmic reticulum membrane, chloroplast envelope, and nucleus. Studies of related genes in other species link the family to seed oil content, freezing tolerance, and lipid accumulation.
