摘要：单宁是植物中一类重要的次生代谢物,广泛存在于植物各组织和器官中,并在植物生长发育过程中发挥至关重要的作用。作为一类具有强大生物活性的化合物,单宁不仅可以帮助植物有效应对各种环境挑战,还在植物的免疫防御系统中发挥核心作用。单宁的合成途径复杂,通常分为前体合成和单宁聚合两个主要阶段。前体合成以芳香族氨基酸为起点,通过一系列酶促反应转化为单宁的基本单元;单宁的聚合则涉及这些单元的交联和聚合,形成具有生物活性的复杂大分子。目前,已有大量研究探讨了单宁的合成途径、调控机制及其对环境的响应,然而仍缺乏系统的总结和全面的概述。本文详细介绍了植物单宁的结构特征,分析了其在植物生长发育中的多重功能,并讨论了植物单宁的生物合成途径。此外,本文总结了环境因素对单宁合成的调控作用,进一步揭示了单宁在植物应对逆境中的潜力,特别是在增强植物抗逆性和生态适应性方面的应用前景。最后,对当前植物单宁研究中尚未解决的问题和未来研究方向进行了分析和展望,旨在为植物单宁的合理开发与应用提供理论依据,推动其在植物抗逆性提升、生态适应性增强以及植物生态功能优化等方面的应用。
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.
