脂氧合酶基因介导果实香气物质合成与调控的研究进展OA

Lipoxygenase(LOX)is a key enzyme in the fatty acid metabolic pathway,which catalyzes the oxygenation of unsaturated fatty acids and their corresponding esters.Its primary metabolites,C6 and C9 aldehydes as well as their matching alcohols,constitute the dominant aromatic compounds in ripe pomaceous fruits.To comprehensively elucidate the functional patterns and molecular mechanisms by which lipoxygenase regulates fruit aroma,this paper systematically reviews recent relevant research literatures.The review covers the major aromatic components of fruit,biosynthetic pathways of fruit aroma compounds,the molecular mechanisms whereby LOX genes govern aroma formation,and the biological functions of LOX during fruit development.It aims to provide theoretical references for fruit tree breeding and mechanistic investigations into the biosynthesis of fruit aroma substances.
