外源添加物质对Cu的植物毒害调节机理研究进展

铜过量会导致植物生长、酶系统平衡、细胞亚显微结构、蛋白质合成、核酸代谢等受到不同程度影响,最终,影响人类健康和生态系统平衡。研究表明外源添加物质能够调节铜过量对植物的毒害作用,文章主要归纳分析了外源添加硅(Si)、油菜素内酯(BR)、一氧化氮(NO),以及其他物质对Cu的植物毒害机理调节机制。但目前在离子载体、蛋白质组、基因组等调节机理方面,以及外源添加物质对植物的适用性、外界条件的影响等方面的研究较为缺乏,未来研究可从这些方向进行深入,完善Cu对植物毒害的系统研究。

Regulation Mechanism of Exogenous Substances on Cu Poison in Plant

Excessive Cu can lead to different degrees of influence on plant growth, enzyme system balance, cell submicroscopic structure, protein synthesis, nucleic acid metabolism and so on, eventually affect human health and ecosystem balance. Studies show that the exogenous substances can regulate the toxic effects of excessive copper on plants. This paper summarizes and analyzes the regulation mechanism of exogenous silicon (Si), brassinolide (BR), nitric oxide (NO) and other substances on excessive Cu toxicity. However, current researches on the mechanism of ion carrier, proteome, genome, the applicability of exogenous substances to plants and the influence of external conditions, are deficient. Future research can be carried out on these aspects to improve the systematic research of Cu poison in plant.
