Summary Plant oils are valuable commodities for food, feed, renewable industrial feedstocks and biofuels. To increase vegetable oil production, here we show that the nonspecific phospholipase C6 (NPC6) promotes seed production in Brassicaceae species Arabidopsis, Camelina oilseed rape. Overexpression of NPC6 increased content, weight yield both Arabidopsis Camelina, whereas knockout decreased content size. is associated with chloroplasts microsomal membranes, hydrolyzes phosphatidylcholine galactolipids to produce diacylglycerol. Knockout overexpression increased, respectively, flux fatty acids from phospholipids into triacylglycerol production. Candidate‐gene association study rape indicates only BnNPC6.C01 four homeologues NPC6s yield. Haplotypic analysis favorable haplotype can These results indicate membrane glycerolipid turnover accumulate TAG seeds has a great application potential improvement.
