Engineered to reduce linolenic acid content, MON 87705 suppresses FATB and FAD2, endogenous genes and encoding enzymes that play a role in the biosynthesis of fatty acids. This alteration more than triples oleic acid content, raising it from approximately 20% to 70% of all fatty acids, and reduces the levels of linoleic acid, stearic acid and palmitic acid present in seeds.[6]
