Influence of heterotrophs on phage infection of marine picocyanobacteria [PDF]

mSystems
Picocyanobacteria Prochlorococcus and Synechococcus coexist with lytic phages and heterotrophic bacteria in the oceans. These phages are a significant cause of mortality, while heterotrophic bacteria can increase Prochlorococcus fitness by reducing ...

A curated protein dataset for taxonomic classification of Prochlorococcus and Synechococcus in metagenomes [PDF]

Scientific Data
Prochlorococcus and Synechococcus are abundant marine picocyanobacteria that contribute significantly to ocean primary production. Recent genome sequencing efforts, including those presented here, have yielded a large number of high-quality reference ...

Rival phytoplankton contribute to the cross protection of Prochlorococcus from oxidative stress [PDF]

Applied and Environmental Microbiology
The marine cyanobacterium Prochlorococcus numerically dominates the phytoplankton communities in all lower latitude, open ocean environments. Having lost the catalase gene, Prochlorococcus is highly susceptible to exogenous hydrogen peroxide (H2O2 ...

Differential Timing for Glucose Assimilation in Prochlorococcus and Coexistent Microbial Populations in the North Pacific Subtropical Gyre

Microbiology Spectrum, 2022
The marine cyanobacterium Prochlorococcus can utilize glucose as a source of carbon. However, the relative importance of inorganic and organic carbon assimilation and the timing of glucose assimilation are still poorly understood in these numerically ...

Prochlorococcus Exudate Stimulates Heterotrophic Bacterial Competition with Rival Phytoplankton for Available Nitrogen

mBio, 2022
The marine cyanobacterium Prochlorococcus numerically dominates the phytoplankton community of the nutrient-limited open ocean, establishing itself as the most abundant photosynthetic organism on Earth.

Production and cross-feeding of nitrite within Prochlorococcus populations

mBio, 2023
Prochlorococcus is an abundant photosynthetic bacterium in the open ocean, where nitrogen (N) often limits phytoplankton growth. In the low-light-adapted LLI clade of Prochlorococcus, nearly all cells can assimilate nitrite (NO2−), with a subset capable ...

Glucose uptake and its effect on gene expression in prochlorococcus. [PDF]

PLoS ONE, 2008
The marine cyanobacteria Prochlorococcus have been considered photoautotrophic microorganisms, although the utilization of exogenous sugars has never been specifically addressed in them.

Presence of Prochlorococcus in the aphotic waters of the western Pacific Ocean [PDF]

Biogeosciences, 2014
Prochlorococcus, the smallest but most abundant marine primary producer, plays an important role in carbon cycling of the global ocean. As a phototroph, Prochlorococcus is thought to be confined to the euphotic zone, with commonly observed maximum depths

Dependence of the cyanobacterium Prochlorococcus on hydrogen peroxide scavenging microbes for growth at the ocean's surface. [PDF]

PLoS ONE, 2011
The phytoplankton community in the oligotrophic open ocean is numerically dominated by the cyanobacterium Prochlorococcus, accounting for approximately half of all photosynthesis.
