摘　　要：WRKY蛋白是被广泛研究的一类DNA特异结合转录因子,其通过结合植物次生代谢生物合成途径关键酶基因的启动子元件来调节代谢过程。次生代谢物种类繁多,结构多样,在植物中广泛存在,在自然界中起重要作用,具有较高的应用价值。综述了WRKY转录因子的起源、进化、结构,及其对萜类、黄酮类、生物碱等次生代谢物生物合成的调控,为植物次生代谢物的进一步开发利用提供参考,同时也为植物次生代谢途径的研究提供依据。WRKY protein is a class of DNA specific transcription factor which is widely researched, and it regulates the process of secondary metabolism biosynthesis pathway by combining the promoter elements of key enzyme in plant. Secondary metabolites with various structures widely exist in plants. They possess high values of application and play an important role in nature. The origin, evolution, structure of WRKY transcription factors and their roles in the regulation of terpenoids, alkaloids, flavonoids and other secondary metabolites biosynthesis were reviewed, in order to provide references for further development and utilization of plant secondary metabolites, and also provide a foundation for the researches of plant secondary metabolic pathways.
