Diversity and evolution of phycobilisomes in marine Synechococcus spp.: a comparative genomics study [PDF]

, 2007
Background Marine Synechococcus owe their specific vivid color (ranging from blue-green to orange) to their large extrinsic antenna complexes called phycobilisomes, comprising a central allophycocyanin core and rods of variable phycobiliprotein ...

¿Flujo acústico, la “pequeña invención” de las cianobacterias?

Arbor: Ciencia, Pensamiento y Cultura, 2010
Los mecanismos de bombeo en microingeniería aparecieron al principio de la década de los 90. El principio detrás de esto es el de flujo acústico. ¿Ha descubierto la Naturaleza este invento de hace 2.700 millones de años? Algunas cianobacterias marinas de

Prochlorococcus and Synechococcus have evolved different adaptive mechanisms to cope with light and UV stress [PDF]

, 2012
Prochlorococcus and Synechococcus, which numerically dominate vast oceanic areas, are the two most abundant oxygenic phototrophs on Earth. Although they require solar energy for photosynthesis, excess light and associated high UV radiations can induce ...

On the Mysterious Propulsion of Synechococcus

PLoS ONE, 2012
We propose a model for the self-propulsion of the marine bacterium Synechococcus utilizing a continuous looped helical track analogous to that found in Myxobacteria [1]. In our model cargo-carrying protein motors, driven by proton-motive force, move along a continuous looped helical track.

Discovery of Euryhaline Phycoerythrobilin-Containing Synechococcus and Its Mechanisms for Adaptation to Estuarine Environments

mSystems, 2020
Synechococcus are among the most abundant and widely distributed picocyanobacteria on earth. Cluster 5 phycoerythrobilin-containing (PEB-containing) Synechococcus, the major marine Synechococcus, were considered to prefer high salinity, and they are ...

Distribution of Synechococcus in the dark ocean [PDF]

Aquatic Microbial Ecology, 2011
Synechococcus is widely distributed in the world's ocean surfaces, and is often found in sediment traps. However, its distribution and ecological importance have not been well studied in meso- and bathypelagic waters. We measured Synechococcus abundance in the Suruga Bay (central Japan) and the subtropical NW Pacific.

Mixotrophic plankton and Synechococcus distribution in waters around Svalbard, Norway during June 2019

, 2021
In order to understand the influence of summer conditions (extended daylight, warmer temperature, increased meltwater, increased suspended load and nutrient chemistry) on the distribution of phytoplankton (diatoms & flagellates) and picoplankton ...

Energy transfer and trapping in Synechococcus WH 7803 [PDF]

Photosynthesis Research, 2017
Excitation energy transfer (EET) and trapping in Synechococcus WH 7803 whole cells and isolated photosystem I (PSI) complexes have been studied by time-resolved emission spectroscopy at room temperature (RT) and at 77 K. With the help of global and target analysis, the pathways of EET and the charge separation dynamics have been identified.

Synechococcus Assemblages across the Salinity Gradient in a Salt Wedge Estuary

Frontiers in Microbiology, 2017
Synechococcus are the most abundant and widely distributed picocyanobacteria in the ocean. The salt-wedge type of estuary possesses the complete horizontal and vertical gradient of salinity together with other physical and chemical parameters.

A Ubiquitously Conserved Cyanobacterial Protein Phosphatase Essential for High Light Tolerance in a Fast-Growing Cyanobacterium

Microbiology Spectrum, 2022
Synechococcus elongatus UTEX 2973, the fastest-growing cyanobacterial strain known, optimally grows under extreme high light (HL) intensities of 1,500–2,500 μmol photons m−2 s−1, which is lethal to most other photosynthetic microbes. We leveraged the few
