Pre-fermentative supplementation of unsaturated fatty acids alters the effect of overexpressing ATF1 and EEB1 on esters biosynthesis in red wine

The production of esters is largely influenced by functional gene expressions and the nutrition status of grape must. In this study, the effects of unsaturated fatty acids (UFAs) mixture (including linoleic acid, oleic acid and linolenic acid) on volatile esters of wine fermented with T73::ATF1 (overexpressing ATF1-encoded alcohol acetyltransferases) and T73::EEB (overexpressing EEB1-encoded acyl-CoA: ethanol O-acyltransferases) were...
