摘　　要：铁作为藻类生长发育所必需的矿质营养元素之一,在藻类光合作用、呼吸作用、固氮作用、蛋白质与核酸合成等生理代谢过程中发挥着极为重要的作用.鉴于水体中不同形态铁可被藻类吸收利用,本文综述了铁在水体中的存在形态和循环途径、藻类吸收铁的机理、铁对藻类生长及藻毒素合成的影响,总结了有关微囊藻毒素合成基因及其在铁限制条件下的表达,并对今后铁蛋白基因调控藻类富营养化的研究方向进行了展望,以期为水体富营养化修复技术提供参考.Iron, as one of the essential mineral elements for algae growth, plays an extremely im portant role in the physiological processes such as plant photosynthesis, respiration, nitrogen fixa tion, protein and nucleic acid synthesis. In view of the fact that iron in different forms could be ab sorbed and utilized by algae, the existing forms and circulation approaches in the aquatic environ ment, the absorption mechanism by algae, and the effects on algae growth and microcystin synthesis were reviewed in this paper. The relevant microcystin synthesis genes and their expression under iron restricted conditions were summarized, and the research directions for harmful algal blooms reg ulation and control by ferritin genes were suggested. It was hoped to provide the reference for eu trophication remediation technology.
