Ecological Genomics of Marine Picocyanobacteria [PDF]

Microbiology and Molecular Biology Reviews, 2009
SUMMARYMarine picocyanobacteria of the generaProchlorococcusandSynechococcusnumerically dominate the picophytoplankton of the world ocean, making a key contribution to global primary production.Prochlorococcuswas isolated around 20 years ago and is probably the most abundant photosynthetic organism on Earth.

Photoinhibition in marine picocyanobacteria

Physiologia Plantarum, 2017
Marine Synechococcus and Prochlorococcus cyanobacteria have different antenna compositions although they are genetically near to each other, and different strains thrive in very different illumination conditions. We measured growth and photoinhibition of PSII in two low‐light and one high‐light Prochlorococcus strains and in one Synechococcus strain ...

Picocyanobacteria in Adriatic transitional environments

Estuarine, Coastal and Shelf Science, 2007
Abstract In the marine realm picoplanktonic cyanobacteria (PC) show a broad distribution from the surface ocean to the offshore and coastal waters of semi-enclosed seas and, because of their photoheterotrophy, they are responsible for a substantial fraction of both primary production and organic matter degradation/utilization.

Picocyanobacteria and Bacteria in Lake Kinneret

International Review of Hydrobiology, 1991
AbstractIn Lake Kinneret, we have been monitoring the numbers and depth distributions of bacteria and picocyanobacteria since early 1988. Picocyanobacteria were found throughout the year at all depths, at concentrations ranging from < 103 to 105 cells·ml−1. Highest abundances were recorded during summer and fall in the epilimnion.

Novel psychrotolerant picocyanobacteria isolated from Chesapeake Bay in the winter

Journal of Phycology, 2015
Picocyanobacteria are major primary producers in the ocean, especially in the tropical or subtropical oceans or during warm seasons. Many “warm” picocyanobacterial species have been isolated and characterized. However, picocyanobacteria in cold environments or cold seasons are much less studied.

Non-viral predators of marine picocyanobacteria

Trends in Microbiology
The Earth's most abundant photosynthetic cells, the picocyanobacteria - Prochlorococcus and Synechococcus - play a fundamental global role in aquatic ecosystems. The success of these picocyanobacteria is interpreted through a cross-scale systems framework that integrates bottom-up controls on growth (e.g., nutrients and light), diversity, and the ...

Significant silicon accumulation by marine picocyanobacteria

Nature Geoscience, 2012
Diatoms—unicellular algae that form substantial blooms in cold, nutrient-rich waters—are thought to be responsible for the export of marine silica to depth. An analysis of the elemental composition of marine cyanobacteria suggests that picocyanobacteria also accumulate significant quantities of silicon.

Distribution of picocyanobacteria and virioplankton in mesotrophic and eutrophic reservoirs: The role of viruses in mortality of picocyanobacteria

Biology Bulletin, 2010
The quantitative distribution and relationships of picocyanobacteria and viruses were studied in the mesotrophic Sheksna and mesoeutrophic Rybinsk reservoirs belonging to the system of the Volga-Baltic Waterway. The share of picocyanobacteria in the sum biomass and production of phytoplankton decreased along with increase in the productivity in the ...
