摘    要:苯丙烷代谢途径是植物中最重要的次生代谢途径之一,在植物抵抗重金属胁迫中直接或间接发挥了抗氧化作用,并能够提高植物对重金属离子的吸收与胁迫耐性。本文就苯丙烷代谢途径核心反应与关键酶系进行了总结,同时分析了木质素、类黄酮及原花青素等关键代谢产物的生物合成过程及相关机制,并以此为基础探讨了苯丙烷代谢途径关键产物响应重金属胁迫的相关机制。此外,结合当前研究现状,就苯丙烷代谢参与植物防御重金属胁迫的相关研究提出展望,以期为重金属污染环境的植物修复提供理论依据。

关 键 词:苯丙烷代谢途径  关键酶系  次生代谢物  重金属胁迫

Abstract:Phenylpropanoid metabolic pathway is one of the most important secondary metabolic pathways in plants. It directly or indirectly plays an antioxidant role in plant resistance to heavy metal stress, and can improve the absorption and stress tolerance of plants to heavy metal ions. In this paper, the core reactions and key enzymes of the phenylpropanoid metabolic pathway were summarized, and the biosynthetic processes of key metabolites such as lignin, flavonoids and proanthocyanidins and relevant mechanisms were analyzed. Based on this, the mechanisms of key products of phenylpropanoid metabolic pathway in response to heavy metal stress were discussed. The perspectives on the involvement of phenylpropanoid metabolism in plant defense against heavy metal stress provides a theoretical basis for improving the phytoremediation efficiency of heavy metal polluted environment.
Keywords:phenylpropanoid metabolic pathway  key enzymes  secondary metabolites  heavy metal stress
