Coexistence of Photosynthetic Marine Microorganisms, Viruses and Grazers: Towards Integration in Ocean Ecosystem Models

open access: yesEnvironmental Microbiology, Volume 28, Issue 4, April 2026.
Our study explores coexistence regimes of a virus and a zooplankton with a single phytoplankton for different model structures (left panel). The inclusion of an infected class and a resistant class is sufficient to generate coexistence regimes (middle panel). Using algebraic solutions, we optimise our model emphasising the importance of including viral

Bacteriophages isolated from Lake Michigan demonstrate broad host-range across several bacterial phyla [PDF]

open access: yes, 2015
BACKGROUND: The study of bacteriophages continues to generate key information about microbial interactions in the environment. Many phenotypic characteristics of bacteriophages cannot be examined by sequencing alone, further highlighting the necessity ...

Transcriptome Analysis of a Bloom-Forming Cyanobacterium Microcystis aeruginosa during Ma-LMM01 Phage Infection

open access: yesFrontiers in Microbiology, 2018
Microcystis aeruginosa forms massive blooms in eutrophic freshwaters, where it is constantly exposed to lytic cyanophages. Unlike other marine cyanobacteria, M.

Linking Light-Dependent Life History Traits with Population Dynamics for Prochlorococcus and Cyanophage

open access: yesmSystems, 2020
Prochlorococcus cyanobacteria grow in diurnal rhythms driven by diel cycles. Their ecology depends on light, nutrients, and top-down mortality processes, including lysis by viruses.

Metavirome Profiling and Dynamics of the DNA Viral Community in Seawater in Chuuk State, Federated States of Micronesia

open access: yesViruses, 2023
Despite their abundance and ecological importance, little is known about the diversity of marine viruses, in part because most cannot be cultured in the laboratory.

Distinct Phage‐Encoded Enzymes for Substitution of Deoxythymidine by Deoxyuridine in Phage Genomes

open access: yesAdvanced Science, Volume 12, Issue 46, December 11, 2025.
Distinct enzymes including dCTP deaminases (Dcds), dTMP phosphatases (Dtms), and dTTP pyrophosphatases (Dtt) are found to be responsible for dU‐DNA biosynthesis in the phages PBS1, DSS3_VP1, and PhiR1‐37. Both PhiR1‐37‐derived and synthetic dU‐DNA are resistant to cleavage by restriction enzymes and Cas12a nuclease targeting dT‐containing sites.

Biogeography of Virioplankton Abundance and Subcluster Patterns in the Northwest Pacific: A Large‐Scale Perspective

open access: yesMicrobiologyOpen, Volume 14, Issue 6, December 2025.
Enhanced‐resolution flow cytometry combined with phenotypic diversity analysis reveals four consistent viral subclusters and a fifth restricted to the Yellow Sea across the Northwest Pacific. These results identify a cryptic diversity hotspot in the Luzon Strait and demonstrate how environmental and biological gradients shape large‐scale patterns in ...

An Estuarine Cyanophage S-CREM1 Encodes Three Distinct Antitoxin Genes and a Large Number of Non-Coding RNA Genes

open access: yesViruses, 2023
Cyanophages play important roles in regulating the population dynamics, community structure, metabolism, and evolution of cyanobacteria in aquatic ecosystems.

A novel uncultured marine cyanophage lineage with lysogenic potential linked to a putative marine Synechococcus 'relic' prophage [PDF]

open access: yes, 2019
Marine cyanobacteria are important contributors to primary production in the ocean and their viruses (cyanophages) affect the ocean microbial communities.

Putative prophages related to lytic tailless marine dsDNA phage PM2 are widespread in the genomes of aquatic bacteria [PDF]

open access: yes, 2007
Background The origin and evolution of viruses is currently a heavily discussed issue. One element in this discussion is the innate viral "self" concept, which suggests that viral structures and functions can be divided into two categories.
