Mapping the transcriptional landscape of algal resistance to viral infection reveals a core expression program

New Phytologist, Volume 248, Issue 3, Page 1368-1384, November 2025.
Summary Algal blooms and their demise by viruses drive global‐scale ecological processes in the ocean. These blooms form the foundation of marine food webs, regulate microbial communities, and shape biogeochemical cycles. Although algal populations are constantly infected by viruses, resistant subpopulations frequently emerge after the infection.

Cyanophages: Starving the Host to Recruit Resources [PDF]

Current Biology, 2016
Phytoplankton and the viruses that infect them are locked in an evolutionary arms race, the nature of which is presently being revealed. A new study shows that cyanophage-mediated inhibition of CO2 fixation enables the phages to recruit photosynthetically formed redox and ATP to fulfill their nucleotide and metabolic demand.

Comprehensive phylogenetic analysis of the ribonucleotide reductase family reveals an ancestral clade

eLife, 2022
Ribonucleotide reductases (RNRs) are used by all free-living organisms and many viruses to catalyze an essential step in the de novo biosynthesis of DNA precursors. RNRs are remarkably diverse by primary sequence and cofactor requirement, while sharing a

First description of a cyanophage infecting the cyanobacterium Arthrospira platensis (Spirulina) [PDF]

, 2013
International audienceCyanobacteria constitute a versatile group of photosynthetic bacteria of immense commercial and ecological importance. Some species of this group are cultivated and sold as food because of their high nutritional value.

Combatting cyanobacteria with hydrogen peroxide: a laboratory study on the consequences for phytoplankton community and diversity [PDF]

, 2015
Experiments with different phytoplankton densities in lake samples showed that a high biomass increases the rate of hydrogen peroxide (HP) degradation and decreases the effectiveness of HP in the selective suppression of dominant cyanobacteria.

Using the diel cycle of ocean microbes to better understand their biogeochemical functions

Limnology and Oceanography Letters, Volume 10, Issue 4, Page 434-447, August 2025.
Abstract The daily cycle of solar radiation has a profound influence in structuring the physiology of microbes in the euphotic zone and subsequently setting the degree of coupling across trophic levels within ocean ecosystems. There has been an upsurge of interest in the biological role of the diel cycle and the ability to probe it using molecular ...

Diel transcriptional response of a California Current plankton microbiome to light, low iron, and enduring viral infection. [PDF]

, 2019
Phytoplankton and associated microbial communities provide organic carbon to oceanic food webs and drive ecosystem dynamics. However, capturing those dynamics is challenging. Here, an in situ, semi-Lagrangian, robotic sampler profiled pelagic microbes at

Radical mechanism of cyanophage phycoerythrobilin synthase (PebS)

Biochemical Journal, 2011
PEB (phycoerythrobilin) is a pink-coloured open-chain tetrapyrrole molecule found in the cyanobacterial light-harvesting phycobilisome. Within the phycobilisome, PEB is covalently bound via thioether bonds to conserved cysteine residues of the phycobiliprotein subunits.

An atomic force microscopy investigation of cyanophage structure [PDF]

Micron, 2012
Marine viruses have only relatively recently come to the attention of molecular biologists, and the extraordinary diversity of potential host organisms suggests a new wealth of genetic and structural forms. A promising technology for characterizing and describing the viruses structurally is atomic force microscopy (AFM).
