摘要：植物次生代谢物作为调节生长发育的调节剂和防御物质重要组成部分,其化合物种类是极其复杂的。苯并噁嗪类化合物(benzoxazinoids,BXs)作为生物碱家族的次生代谢物之一,具有天然植物活性物质成分,被应用在药物成分和食品添加剂等领域,其药理和保健作用已成为新的研究热点。当前,有关BXs化合物研究都集中在禾本科玉米和小麦中,其调节机制研究还不够深入。本文从BXs化合物的组成、分类及代谢途径,详细介绍了其次生代谢过程,进化特征表明其存在特有生物合成簇结构。归纳总结了BXs化合物在植物生长发育中扮演着防御作用,包括对昆虫的防御作用、微生物的相互作用和竞争植物的化感作用。并且BXs作为信号分子介导植物对金属离子螯合、响应外界环境刺激和参与植物激素的调节剂,揭示了BXs化合物在植物与环境条件相互作用中的重要功能。同时,总结出BXs化合物目前研究所面临的问题及解决办法,相信随着BXs化合物的深入研究必将有力地促进新型农业生产和可持续战略实践的发展,有助于深入挖掘其潜在应用价值,解决当前农林业生产面临的多重挑战。
Plant secondary metabolites are important components of regulators and defense substances that regulate growth and development,and their compound types are extremely complex.Benzoxazinoids(BXs),as one of the secondary metabolites of the alkaloid family,have natural plant active ingredients and are used in the fields of pharmaceutical ingredients and food additives.Their pharmacological and health effects have become a new research hotspot.At present,the study on BXs compounds is concentrated on gramineae corn and wheat,and the research on their regulatory mechanisms is not in-depth enough.In this paper,the secondary metabolic process of BXs compounds is introduced in detail from the composition,classification and metabolic pathways.The evolutionary characteristics indicate that they have a unique biosynthetic cluster structure.It is summarized that BXs compounds play a defensive role in plant growth and development,including defense against insects,microbial interactions and allelopathy in competing plants.Moreover,BXs serve as signaling molecules that mediate plant chelation of metal ions,respond to external environmental stimuli and participate in the regulators of plant hormones,revealing the important function of BXs compounds in the interaction between plants and environmental conditions.Concurrently,it summarizes the issues and solutions faced by BXs compounds in the current research.It is believed that with the in-depth research of BXs compounds,it will surely promote the development of new agricultural production and sustainable strategic practices,help to deeply explore their potential application value,and solve the multiple challenges facing current agricultural and forestry production.
