Cyanobacteria are a phylum of bacteria which are believed to be the oldest photosynthetic prokaryotic microorganisms on earth. The phylogenetic group of cyanobacteria was thought to be one of the prokaryotes that contain monoploid, oligoploid and polyploid species, and one obstacle to engineering cyanobacteria is their polyploidy genome. In recent years, the ploidy level of cyanobacteria was found to be influenced by growth phase and by multiple genetic and environmental factors. In the present article, we reviewed the progress, analytical methods and influencing factors on the cyanobacterial ploidy, and discussed the significance of cyanobacterial polyploidy regarding to environmental ecology and biotechnology. Based on this observation, the future research directions in this field are prospected.
蓝细菌是细菌的一个门类，被认为是地球上最古老的进行光合作用的原核微生物。蓝细菌的系统发育群体被认为是包含单倍体、寡倍体和多倍体物种的原核生物之一，而对蓝细菌进行工程改造的一个障碍是它们的多倍体基因组。近年来，发现蓝细菌的倍性水平受生长阶段以及多种遗传和环境因素的影响。在本文中，我们综述了蓝细菌倍性方面的进展、分析方法和影响因素，并讨论了蓝细菌多倍性在环境生态学和生物技术方面的意义。基于这一观察结果，对该领域未来研究方向进行了展望。
