Frontiers in Microbiology, 2019 Marine picocyanobacteria are ubiquitous primary producers across the world’s oceans, and play a key role in the global carbon cycle. Recent evidence stemming from in situ investigations have shown that picocyanobacteria are able to sink out of the ...

The Distinctive Regulation of Cyanobacterial Glutamine Synthetase [PDF]
, 2018 Glutamine synthetase (GS) features prominently in bacterial nitrogen assimilation as it catalyzes the entry of bioavailable nitrogen in form of ammonium into cellular metabolism. The classic example, the comprehensively characterized GS of enterobacteria,

Global genetic capacity for mixotrophy in marine picocyanobacteria [PDF]
The ISME Journal, 2016 Abstract The assimilation of organic nutrients by autotrophs, a form of mixotrophy, has been demonstrated in the globally abundant marine picocyanobacterial genera Prochlorococcus and Synechococcus. However, the range of compounds used and the distribution of organic compound uptake genes within picocyanobacteria are unknown.

Thermal Limits and Decline of Synechococcus Under Accelerated Warming and Marine Heatwaves. [PDF]
Glob Chang BiolMarine picophytoplankton, including Synechococcus, contribute ~20% of ocean primary production and are considered thermally resilient. However, 7 years of observations and experiments in the Red Sea show that recent extreme warming reduced Synechococcus abundance. Seawater temperatures during marine heatwaves in 2023–2024 exceeded the thermal limits of

Dynamics of auto- and heterotrophic picoplankton and associated viruses in Lake Geneva [PDF]
, 2014 Microbial dynamics have rarely been investigated in Lake Geneva, known as the largest lake in western Europe. From a 5-month survey, we report dynamic patterns of free-living virus, bacteria and small phytoplankton abundances in response to a variety of ...

Phenotypic plasticity in freshwater picocyanobacteria
Environmental Microbiology, 2017 Summary Picocyanobacteria can occur as single‐cell (Pcy) or as colonies (CPcy). Published evidence suggests that some Pcy strains have the capability to aggregate under certain culture conditions, however this has not been demonstrated to occur in natural environments.

Toxic Picoplanktonic Cyanobacteria—Review
Marine Drugs, 2015 Cyanobacteria of a picoplanktonic cell size (0.2 to 2.0 µm) are common organisms of both freshwater and marine ecosystems. However, due to their small size and relatively short study history, picoplanktonic cyanobacteria, in contrast to the ...

Picocyanobacteria From a Clade Of Marine Cyanobium Revealed Bioactive Potential Against Microalgae, Bacteria, And Marine [PDF]
, 2015 The production of bioactive compounds either toxic or with pharmacological applications by cyanobacteria is well established. However, picoplanktonic forms within this group of organisms have rarely been studied in this context.
