摘　　要：水体富营养化及蓝藻水华的频繁发生,严重破坏水域生态系统,有毒水华蓝藻产生的藻毒素,污染水体且危害水生动物和人类健康。本文综述了水华蓝藻的次级代谢产物藻毒素及藻毒素合成基因的国内外研究进展,介绍了蓝藻毒素的类型、不同毒素毒性机理、产毒基因以及利用产毒基因进行产毒蓝藻的分子生物学检测等,并对研究中存在的问题和未来的研究方向进行了展望,目的是为建立有毒水华蓝藻的预警机制、科学评价产毒蓝藻及其藻毒素的生态、环境危害及生态环境治理提供理论和技术支撑。With the aggravation of water eutrophication and continuing outbreak of cyanobacteria blooms, the harmful algal bloom could not only break the structure and the balance of hydrophy-tic ecosystem, but also pose serious health threats on animals and human due to cyanobacteria-toxin production. This paper reviews the progress of research on the secondary metabolites of cyanobacteria bloom toxins and cyanotoxin synthetase gene. The types of cyanotoxins, toxicology of cyanobacterial toxin, cyanotoxin synthetase gene and molecular biology identification for detecting the toxic cyanobacteria were described. Some suggestions on disadvantage of present research about cyanotoxin were put forward. The purpose of this review is to provide a theoretical basis and technological support on scientific evaluation of ecological and environment hazards of toxinproducing cyanobacteria and instituting earlywarning system of cyanotoxins.
