摘要: 植物次生代谢产物是人类重要的药物及化工原料来源, 其产生与植物正常的生长发育及对环境的适应密切相关, 并受到多种因素的调控。乙烯作为一种植物内源激素, 广泛参与植物的生长、发育、抗逆和次生代谢产物合成等重要生理过程的调控。该文综述了乙烯的信号转导机制及其调控作用; 重点归纳了乙烯对植物次生代谢产物形成所表现出的双重调控效应, 即在一定浓度范围内, 乙烯对植物次生代谢产物的合成起促进作用, 低于或超过该浓度范围则起抑制作用; 并对今后该领域的研究方向进行了展望。

Abstract: Plant secondary metabolites are important natural sources for drugs and chemical raw materials. The formation of these metabolites is closely related to the normal growth and adaptation to environments by plants and could be regulated by a variety of factors. As an endogenous hormone in plants, ethylene plays important roles in regulating most plant physiological processes such as growth, development, stress resistance and secondary metabolite biosynthesis. Here, we review the signal transduction mechanism and regulatory effects of ethylene, especially its dual regulatory effects, on the formation of plant secondary metabolites, namely, how ethylene promotes the biosynthesis of secondary metabolites within a range of concentration in plants but has an inhibitory effect on the formation of secondary metabolites outside of a certain threshold of concentration. We give prospects for further research in this field.

Key words: ethylene, secondary metabolites, signal transduction pathway, dual regulation
