Cyanophages are double-stranded DNA viruses that infect cyanobacteria, and they can be found in both freshwater and marine environments. They have a complex pattern of host ranges and play important roles in controlling cyanobacteria population. Unlike marine cyanophages, for which there have been a number of recent investigations, very little attention has been paid to freshwater cyanophages. This review summarizes the taxonomy and morphology, host range, distribution, seasonal dynamics, and complete genomes of freshwater cyanophages, as well as diagnostic markers that can be used to identify them.

Cyanophages play an important role in nutrient cycling in lakes since they can modulate the metabolism of cyanobacteria. A proper understanding of the impact of cyanophage infection on the metabolism and ecology of cyanobacteria is critical during a complete cycle of harmful algal bloom (HAB). The ecology of cyanophages in marine environments has been well-delineated, but cyanophages in freshwater lakes remain less studied.

Cyanobacteria represent a prevalent category of photosynthetic autotrophs capable of generating deleterious algal blooms, commonly known as cyanobacteria harmful algal blooms (cyanoHABs). These blooms often produce cyanotoxins, which pose risks to public health and ecosystems by contaminating surface waters and drinking water sources. Traditional treatment methods have limited effectiveness.

Horizontal gene transfer events between viruses and hosts are widespread across the virosphere. In cyanophage-host systems, such events often involve the transfer of genes involved in photosynthetic processes. The genome of the lytic cyanophage Ma-LMM01 infecting the toxic, bloom-forming, freshwater NIES-298 contains a homolog of the () gene, which was probably transferred from a cyanobacterial host.

Article Synopsis
- Many freshwater ecosystems are impacted by harmful blooms of cyanobacteria, particularly Microcystis aeruginosa, but the reasons for its dominance in warmer conditions are not fully understood.
- This study employs comparative genomics to explore the unique gene functions and genomic structures of M. aeruginosa, revealing its extensive genetic variability and adaptive strategies for survival in fluctuating environments.
- The findings indicate that M. aeruginosa develops diverse genotypes, utilizes defensive genes, and relies on buoyancy-enhancing exopolysaccharides to withstand environmental stresses and threats from predators, enhancing its resilience compared to other cyanobacteria.
