Are temperature sensitivities of Prochlorococcus and Synechococcus impacted by nutrient availability in the subtropical northwest Pacific?

Limnology and Oceanography, 2020
Temperature sensitivity of phytoplankton growth rate is crucial for predicting the effect of global warming on oceanic primary productivity and the efficiency of the biological carbon pump. To investigate how nutrient availability affects the temperature

The Seasonal Impact of the Island Mass Effect on Coastal Biogeochemistry and Phytoplankton Assemblage: The Case of the Tropical and Volcanic Island of Guadeloupe (French West Indies)

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract The Island Mass Effect (IME) in tropical regions remains understudied, despite its potential to fertilize oligotrophic oceanic gyres and impact on higher trophic levels. Guadeloupe provides an ideal case study of IME due to its diverse nutrient sources, dual exposure to the Caribbean Sea on the western coast and Atlantic Ocean on the eastern ...

Hopanoid lipids may facilitate aerobic nitrogen fixation in the ocean. [PDF]

, 2019
Cyanobacterial diazotrophs are considered to be the most important source of fixed N2 in the open ocean. Biological N2 fixation is catalyzed by the extremely O2-sensitive nitrogenase enzyme.

Viral Lysis Alters the Optical Properties and Biological Availability of Dissolved Organic Matter Derived from Prochlorococcus Picocyanobacteria

Applied and Environmental Microbiology, 2020
The unicellular picocyanobacterium Prochlorococcus is the numerically dominant phytoplankton in the oligotrophic ocean, contributing to the vast majority of marine primary production.

Hi‐C Links Reveal Viral Activity and Infection Within the Free‐Living Microbial Community of a Secondary Chlorophyll Maximum in the Eastern Tropical North Pacific

Environmental Microbiology, Volume 28, Issue 4, April 2026.
Hi‐C sequencing was used to link viral sequences with microbial metagenome assembled genomes in the largely uncultivated waters of an oxygen‐deficient zone's secondary chlorophyll maximum within the Eastern Tropical North Pacific Ocean. ABSTRACT Oxygen‐deficient zones (ODZs) influence global nitrogen cycling as key sites for the removal of bioavailable

Response of Prochlorococcus to varying CO2:O2 ratios [PDF]

The ISME Journal, 2015
Abstract Carbon fixation has a central role in determining cellular redox poise, increasingly understood to be a key parameter in cyanobacterial physiology. In the cyanobacterium Prochlorococcus—the most abundant phototroph in the oligotrophic oceans—the carbon-concentrating mechanism is reduced to the bare essentials.

Development and Bias Assessment of a Method for Targeted Metagenomic Sequencing of Marine Cyanobacteria [PDF]

, 2013
Prochlorococcus and Synechococcus are the most abundant photosynthetic organisms in oligotrophic waters and responsible for a significant percentage of the earth's primary production.

Visualizing Adsorption of Cyanophage P-SSP7 onto Marine Prochlorococcus [PDF]

Scientific Reports, 2017
AbstractMarine cyanobacteria perform roughly a quarter of global carbon fixation, and cyanophages that infect them liberate some of this carbon during infection and cell lysis. Studies of the cyanobacterium Prochlorococcus MED4 and its associated cyanophage P-SSP7 have revealed complex gene expression dynamics once infection has begun, but the initial ...

Independent iron and light limitation in a low-light-adapted Prochlorococcus from the deep chlorophyll maximum

The ISME Journal, 2020
Throughout the open ocean, a minimum in dissolved iron concentration (dFe) overlaps with the deep chlorophyll maximum (DCM), which marks the lower limit of the euphotic zone.

Phosphorus Acquisition Strategies Among Phytoplankton and Free‐Living Bacterial Communities in the Baltic Proper

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Phosphorus is a key element for cellular functions and poses significant challenges for planktonic microbial communities under limited availability. Metagenomics highlighted that heterotrophic bacteria predominantly relied on phosphate scavenging while eukaryotic phytoplankton primarily utilized membrane remodelling to cope with limited phosphorus ...
