Abstract: 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.
