摘　　要：类黄酮物质主要分为黄酮醇、花青素、黄烷酮、黄酮、原花青素、异黄酮以及黄烷醇七大类,其中黄酮醇是分布最广、数量最多的一类,并且是植物果实和花的颜色来源之一。黄酮醇合成酶(flavonol synthase,FLS)在类黄酮代谢中起着十分重要的作用,它是黄酮醇合成的关键酶之一。催化黄酮结构中的C3位羟基化,形成各种黄酮醇类物质。本综述从FLS基因的结构特征、功能、转录调控因子、影响其表达的因素以及与DFR竞争底物、系统进化等方面,结合近三十年来有关FLS的研究报道,综述了FLS的研究进展,有助于进一步弄清楚黄酮醇的功能。Flavonoids include flavone,flavonol,isoflavone,flavanol,flavanone,anthocyanin and proanthocyanidin.Among those flavonoids,flavonols are the most widely distributed species and the color sources of flowers and fruits.Flavonol synthase(FLS)plays an important role in the metabolism of flavonoids.It is one of the key enzymes in the synthesis of flavonols and catalyzes the hydroxylation of C3 in flavones to form various flavonols.This paper summarizes the research progress of FLS from the structural characteristics,functions,transcription factors,factors affecting its expression,the competition with DFR to phylogenetics.Which will contribute to a further understanding of the flavonols functions.
