Dual Regulating Effects of Ethylene on the Formation of Plant Secondary Metabolites

doi:10.3724/SP.J.1259.2014.00626

Abstract

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
