Phylogenetic diversity of nonmarine picocyanobacteria [PDF]
We studied the phylogenetic diversity of nonmarine picocyanobacteria broadening the sequence data set with 43 new sequences of the 16S rRNA gene. The sequences were derived from monoclonal strains isolated from four volcanic high-altitude athalassohaline lakes in Mexico, five glacial ultraoligotrophic North Patagonian lakes and six Italian lakes of ...

Mesozooplankton grazing on picocyanobacteria in the Baltic Sea as inferred from molecular diet analysis. [PDF]
Our current knowledge on the microbial component of zooplankton diet is limited, and it is generally assumed that bacteria-sized prey is not directly consumed by most mesozooplankton grazers in the marine food webs.

Ploidy levels in diverse picocyanobacteria from the Baltic Sea. [PDF]
Abstract In nature, the number of genome or chromosome copies within cells (ploidy) can vary between species and environmental conditions, potentially influencing how organisms adapt to changing environments. Although ploidy levels cannot be easily determined by standard genome sequencing, understanding ploidy is crucial for the ...

Ecophysiological basis of spatiotemporal patterns in picophytoplankton pigments in the global ocean
Information on the intracellular content and functional diversity of phytoplankton pigments can provide valuable insight on the ecophysiological state of primary producers and the flow of energy within aquatic ecosystems.

Marine Synechococcus picocyanobacteria: Light utilization across latitudes
Significance Phytoplankton drives most of the carbon pumping of the world ocean through the photosynthesis process. We show how Synechococcus picocyanobacteria, a very abundant marine phytoplankton, have adapted the light utilization process to colonize different thermal niches.

Unveiling membrane thermoregulation strategies in marine picocyanobacteria [PDF]
Summary The wide latitudinal distribution of marine Synechococcus cyanobacteria partly relies on the differentiation of lineages adapted to distinct thermal environments. Membranes are highly thermosensitive cell components, and the ability to modulate their fluidity can be critical for the fitness of an ecotype in a particular thermal niche.

Picocyanobacteria in Surface Water Bodies
Cyanobacterial harmful algal blooms (CyanoHABs) in lentic, low tidal water bodies with high concentrations of easily assimilated nutrients have generated worldwide concern. However, CyanoHABs often formed from a variety of lesser-known taxa, such as nanocyanobacteria and picocyanobacteria, which are characterized as numerous and ubiquitous in diverse ...

Elucidating the picocyanobacteria salinity divide through ecogenomics of new freshwater isolates [PDF]
AbstractBackgroundCyanobacteria are the major prokaryotic primary producers occupying a range of aquatic habitats worldwide that differ in levels of salinity, making them a group of interest to study one of the major unresolved conundrums in aquatic microbiology which is what distinguishes a marine microbe from a freshwater one?

Picocyanobacteria (Pcy) are important yet understudied components of lake foodwebs. While phylogenetic studies of isolated strains reveal a high diversity of freshwater genotypes, little is known about abiotic drivers associated with Pcy in different ...
