Unraveling the genomic mosaic of a ubiquitous genus of marine cyanobacteria [PDF]

, 2008
Background: The picocyanobacterial genus Synechococcus occurs over wide oceanic expanses, having colonized most available niches in the photic zone. Large scale distribution patterns of the different Synechococcus clades (based on 16S rRNA gene markers)

N:P ratio influences the competition of Microcystis with its picophytoplankton counterparts, Mychonastes and Synechococcus, under nutrient enrichment conditions

Journal of Freshwater Ecology, 2019
We investigated how the N:P ratio can shape the structure of picophytoplankton and Microcystis, which are abundant and widespread in eutrophic lakes. Unialgal culture and coculture batch experiments were conducted to study the growth and interspecific ...

The evolutionary divergence of psbA gene in Synechococcus and their myoviruses in the East China Sea. [PDF]

PLoS ONE, 2014
Marine Synechococcus is a principal component of the picophytoplankton and makes an important contribution to primary productivity in the ocean. Synechophages, infecting Synechococcus, are believed to have significant influences on the distribution and ...

Phylogenetic and Phenogenetic Diversity of Synechococcus along a Yellow Sea Section Reveal Its Environmental Dependent Distribution and Co-Occurrence Microbial Pattern

Journal of Marine Science and Engineering, 2021
Synechococcus is a dominant genus of the coastal phytoplankton with an effective contribution to primary productivity. Here, the phylogenetic and phenogenetic composition of Synechococcus in the coastal Yellow Sea was addressed by sequencing marker gene ...

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

Marine Synechococcus sp. Strain WH7803 Shows Specific Adaptative Responses to Assimilate Nanomolar Concentrations of Nitrate

Microbiology Spectrum, 2022
Marine Synechococcus, together with Prochlorococcus, contribute to a significant proportion of the primary production on Earth. The spatial distribution of these two groups of marine picocyanobacteria depends on different factors such as nutrient ...

Function and evolution of the psbA gene family in marine Synechococcus: Synechococcus sp. WH7803 as a case study [PDF]

The ISME Journal, 2008
Abstract In cyanobacteria, the D1 protein of photosystem II (PSII) is encoded by the psbA multigene family. In most freshwater strains, a D1:1 isoform of this protein is exchanged for a D1:2 isoform in response to various stresses, thereby altering PSII photochemistry.

Virus isolation studies suggest short-term variations in abundance in natural cyanophage populations of the Indian Ocean [PDF]

, 2006
Cyanophage abundance has been shown to fluctuate over long timescales and with depth, but little is known about how it varies over short timescales. Previous short-term studies have relied on counting total virus numbers and therefore the phages which ...

Virus Effect on Marine Synechococcus Spp. Loss in Subtropical Western Pacific Coastal Waters During Winter

Terrestrial, Atmospheric and Oceanic Sciences, 2015
Little is known about microbial processes and the effect that viruses have on Synechococcus spp. in aquatic environments. This study investigated diel variations in the Synechococcus spp. abundance in three size-fractionated water samples (200, 10, and 2

Picocyanobacteria Community and Cyanophage Infection Responses to Nutrient Enrichment in a Mesocosms Experiment in Oligotrophic Waters

Frontiers in Microbiology, 2020
Prochlorococcus and Synechococcus are pico-sized cyanobacteria that play a fundamental role in oceanic primary production, being particularly important in warm, nutrient-poor waters.
