植物单宁合成调控及其对环境的响应机制
Regulation of Plant Tannin Synthesis and Mechanisms of Its Responses to Environment
摘要
Abstract
Tannins are an important class of secondary metabolites in plants,widely distributed in various tissues and organs of plants,and play a crucial role in plant growth and development.As compounds with strong biological activity,tannins not only help plants effectively cope with various environmental challenges but also play a core role in the plant immune defense system.The biosynthesis of tannins is complex and is typically divided into two main stages:Precursor synthesis and tannin polymerization.Precursor synthesis begins with aromatic amino acids,which are converted into the basic units of tannins through a series of enzymatic reactions.Tannin polymerization is involved in the cross-linking and polymerization of these units to form complex macromolecules with biological activity.Although extensive research has been conducted on the synthesis pathways,regulatory mechanisms,and environmental responses of tannins,there is still a lack of systematic summaries and comprehensive overviews.This paper provides a detailed introduction to the structural characteristics of plant tannins,analyzes their multiple functions in plant growth and development,and discusses the biosynthetic pathways of tannins.Additionally,this paper summarizes the regulatory effects of environmental factors on tannin synthesis,further revealing the potential of tannins in helping plants cope with stress,particularly in enhancing plant resistance to stress and ecological adaptability.Finally,this paper analyzes and provides an outlook on unresolved issues in current tannin research and future research directions,aiming to provide theoretical support for the rational development and application of plant tannins,and promoting their application in improving plant stress resistance,enhancing ecological adaptability,and optimizing plant ecological functions.关键词
