Host-like genes are often found in viral genomes. To date, multiple host-like genes involved in photosynthesis and the pentose phosphate pathway have been found in phages of marine cyanobacteria Synechococcus and Prochlorococcus. These gene products

The cyanobacterium Microcystis aeruginosa frequently forms blooms in eutrophic freshwater. Previously, we demonstrated that DNA replication and cell division are coordinated in M. aeruginosa NIES 298, and some part of this coordination is mediated by

ORF69 in the cyanophage infecting Microcystis aeruginosa, Ma-LMM01, shows homology to the family 19 chitinases where the catalytic domain has structural similarity to lysozyme. Chitinases hydrolyze chitin, a β-1, 4-linked monopolymer of N-acetylgluc

The aim of this study was to develop a quantitative real-time reverse transcription-PCR (real-time RT-PCR) assay to detect and quantify mRNA of cyanophages within infected Microcystis aeruginosa cells in a freshwater pond. Laboratory-based data showe

The abundance of potentially Microcystis aeruginosa -infectious cyanophages in freshwater was studied using g91 real-time PCR. A clear increase in cyanophage abundance was observed when M. aeruginosa numbers declined, showing that these factors were

Cyanobacteria and their phages are significant microbial components of the freshwater and marine environments. We identified a lytic phage, Ma-LMM01, infecting Microcystis aeruginosa , a cyanobacterium that forms toxic blooms on the surfaces of fresh

Red tides of Heterocapsa circularisquama have led to serious damage of bivalve aquacultures in western coastal areas of Japan. To understand the whole picture regarding the ecology of this species, it is essential to clarify its overwintering mechani

To develop a real-time PCR method for quantification of the abundance of cyanophages infecting Microcystis aeruginosa in aquatic environments, we characterized three cyanophage clones infecting M. aeruginosa, and compared them to the cyanophage Ma-LM

Temporal changes in hepatotoxin microcystin-producing and non-microcystin-producing Microcystis aeruginosa populations were examined in Lake Mikata, Japan. To monitor the densities of the total M. aeruginosa population and the potential microcystin-p
