AP2/ERF转录因子调控次生代谢产物生物合成的研究进展

Research progress on effect of AP2/ERF transcription factors in regulating secondary metabolite biosynthesis

AP2/ERF转录因子是植物中广泛存在的一类转录因子,该家族转录因子至少含有一段由约60~70个氨基酸组成的保守的AP2/ERF结构域。AP2/ERF转录因子广泛参与植物多种生理过程,包括植株生长、果实成熟、花发育等植物发育进程,以及损伤、病虫害防御、高盐、干旱等逆境胁迫响应过程。近年来,以转录因子为遗传操作靶点的次生代谢工程在提高药用植物活性成分含量和改良植物品质方面得到了快速发展。该文综述了AP2/ERF转录因子调控次生代谢产物生物合成方面的研究进展,为挖掘高效调控靶点,开展药用植物次生代谢调控,靶向性提高中药活性成分含量,实现高品质中药材的可持续供应提供理论依据。

AP2/ERF transcription factor is a kind of transcription factors widely existing in plants, and contains at least a conserved AP2/ERF domain composed of about 60-70 amino acids. AP2/ERF transcription factors are widely involved in a variety of physiological processes in plants, including plant development, fruit ripening, flower development and other plant development processes, as well as such stress response processes as damage, pathogen defense, high-salt condition and drought. In recent years, secondary metabolic engineering that takes transcription factors as genetic manipulation targets has developed rapidly in improving the content of active ingredients and the quality of medicinal plants. This paper reviews the recent progress in the regulation of secondary metabolites biosynthesis with AP2/ERF transcription factors, and provides theoretical basis for the exploration of efficient regulatory targets, the regulation of secondary metabolites in medicinal plants, the targeted improvement of the content of active ingredients in traditional Chinese medicine, and the sustainable supply of high-quality traditional Chinese medicines.
