摘　　要：花青素属于类黄酮类化合物,是一类具有水溶性的天然色素。自然条件下,花青素以糖苷(花青素苷)形式存在。花青素苷的种类、含量和分布是植物花、茎、叶、果实等器官组织呈现不同色彩的重要原因。花青素苷在植物抵抗干旱、低温、盐胁迫、低氮等非生物胁迫及火疫病菌、软腐病菌、黄萎病菌等生物胁迫中也具有重要的作用。本文主要从植物花青素苷的生物合成代谢途径、花青素苷在植物响应非生物胁迫和生物胁迫中的分子作用机制两个方面进行综述,并对其今后的研究方向进行了展望,以期更好地揭示其在植物响应逆境胁迫中的分子作用机制,为培育花青素苷介导的高抗性植物提供理论依据。Anthocyanins,belonging to flavonoid compounds,are a kind of water-soluble natural pigments.Under natural conditions,anthocyanins always exist in the form of glycosides combined with glycosylation.The type,content and distribution of anthocyanins in plants contributed to the color of organs,such as plant flowers,stems,leaves and fruits.In addition,anthocyanins also play important roles in enhancing the tolerance and resistance of abiotic stresses such as drought,low temperature,salt stress,low nitrogen,and biotic stresses such as Erwinia amylovora,Pectobacterium carotovorum,and Verticillium dahliae.In this paper,we mainly reviewed the biosynthesis and metabolism of plant anthocyanins,the molecular mechanism of plant anthocyanins in the response to the biotic and abiotic stress,and proposed the direction for the future studies.This paper would be helpful for understanding and applying the molecular mechanism of plant anthocyanins in the response to the biotic and abiotic stress,and provides references for the cultivation of anthocyaninmediated high tolerance and resistance plants.
