LPAT2 — Camelina sativa

Summary

CsLPAT2 (CSA06G033410) on chromosome 6 of Camelina sativa encodes a lysophosphatidate acyltransferase with enzyme activity 2.3.1.51, belonging to the acyltransferase and glycerol-acyltransferase domain families. The gene is associated with adiposome formation, CDP-diacylglycerol anabolism, and fatty acid elongation, and its product localizes to the adiposome, endoplasmic reticulum membrane, and endomembrane system. It is linked to pathways including synthesis of phosphatidic acid and phospholipid biosynthesis I. Associations with traits include oleic acid content and photosynthetic rate, while phenotypes connected to LPAT2 involve seed size, seed oil production, plant development, female gametophyte development, vegetative and reproductive growth, root growth, and phospholipid content. Studies of related genes in other species link the family to embryo development, triacylglycerol composition, and female gametophyte lethality.
