Role of Phytohormones as Elicitors in Plant Secondary Metabolite Synthesis

Abstract

Phytohormones play a crucial function in regulating various physiological processes in plants, including the biosynthesis of secondary metabolites. This chapter explores the intricate mechanisms by which phytohormones act as elicitors, stimulating the biosynthesis of secondary metabolites which are essential for plant defense and adaptation. The diverse classes of phytohormones- such as cytokinins, ethylene, auxins, gibberellins, abscisic acid, and jasmonates are discussed with an emphasis on their regulatory functions in plant defense, growth and development. Additionally, the specific roles of these phytohormones as elicitors in secondary metabolite synthesis pathways have also been discussed. Moreover, this chapter explores the interactions between different phytohormones and their synergistic or antagonistic effects on secondary metabolite synthesis. Understanding the intricate interplay between phytohormones and secondary metabolites not only sheds light on plant physiology but also has significant implications for agriculture, pharmaceuticals, and biotechnology. This chapter serves as a valuable resource for researchers who possess keen interest in unravelling the complexities of plant biochemistry and harnessing the potential of phytochemicals for various applications.
