摘　　要：黄酮醇作为一类重要的类黄酮化合物,是广泛存在于植物体内与植物的营养及外观品质密切相关的一类重要的次生代谢产物。黄酮醇生物合成关键基因的表达模式及表达量是决定黄酮醇生物合成进程及含量的重要因素,因此了解植物黄酮醇类化合物生物合成关键基因的研究进展对于植物黄酮醇类化合物生物合成的有效调控具有重要意义。本文综述了植物黄酮醇生物合成途径上关键基因(PAL,C4H,4CL,CHS,FLS)的克隆、分布、特性及其对外源环境条件应答的最新研究进展,以期为植物黄酮醇的生物合成后续研究提供参考依据。Flavonol,as an important type of flavonoids,is an important class of secondary metabolites that widely distribute in plants and is closely related to the nutrient and appearance quality of plants.The expression pattern and the expression level of the key genes of flavonol biosynthesis are important factors that determine the biosyhthetic process and contents of flavonols.Therefore,understanding the research progress on key genes of flavonol biosynthesis is of great significance to the effective regulation of biosynthesis of flavonols in plants. In this paper,the latest research progress on the clone,distribution,characteristics and the responses to the outer environmental conditions of the key genes（ PAL,C4 H,4 CL,CHS,FLS） on flavonol biosynthetic pathways were reviewed,in order to provide reference for future studies on flavonol biosynthesis.
