Regulatory and metabolic adaptations in the nitrogen assimilation of marine picocyanobacteria
FEMS Microbiology Reviews, 2022 AbstractProchlorococcus and Synechococcus are the two most abundant photosynthetic organisms on Earth, with a strong influence on the biogeochemical carbon and nitrogen cycles. Early reports demonstrated the streamlining of regulatory mechanisms in nitrogen metabolism and the removal of genes not strictly essential.

Novel Synechococcus Genomes Reconstructed from Freshwater Reservoirs
Frontiers in Microbiology, 2017 Freshwater picocyanobacteria including Synechococcus remain poorly studied at the genomic level, compared to their marine representatives. Here, using a metagenomic assembly approach we discovered two novel Synechococcus sp.

PtrA is required for coordinate regulation of gene expression during phosphate stress in a marine Synechococcus [PDF]
, 2010 Previous microarray analyses have shown a key role for the two-component system PhoBR (SYNW0947, SYNW0948) in the regulation of P transport and metabolism in the marine cyanobacterium Synechococcus sp. WH8102. However, there is some evidence that another

Adaptive thermostability of light-harvesting complexes in marine picocyanobacteria [PDF]
The ISME Journal, 2016 Abstract Marine Synechococcus play a key role in global oceanic primary productivity. Their wide latitudinal distribution has been attributed to the occurrence of lineages adapted to distinct thermal niches, but the physiological and molecular bases of this ecotypic differentiation remain largely unknown.

Marine Synechococcus picocyanobacteria: Light utilization across latitudes
Proceedings of the National Academy of Sciences, 2021 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 ...

Allelopathic activity of the Baltic picocyanobacterium Synechocystis sp.
Annales Universitatis Paedagogicae Cracoviensis Studia Naturae, 2017 Allelopathic compounds produced by picocyanobacteria could affect the growth and development of biological systems. The main aim of this study was to investigate the influence of unknown allelochemicals obtained from picocyanobacterium Synechocystis sp ...

Photosynthetica, 2021 Synechococcus is one of the most abundant photoautotrophic picoplankton in the marine ecosystem. However, it is not clear how Synechococcus assemblages respond to light intensity variation in a genus group.

Uptake of Hg2+ by picocyanobacteria in natural water from four Andean lakes
E3S Web of Conferences, 2014 In lake food webs, planktonic bacteria and algae represent the greatest bioconcentration step for Hg2+ and monomethyl-Hg (MeHg). As they are the most abundant organisms in planktonic trophic webs and also the main food resource for herbivorous plankton ...
