Ecology and evolution of lanthipeptides in marine picocyanobacteria
… produced by strains of the ubiquitous marine picocyanobacteria Prochlorococcus and Synechococcus. Unlike other lanthipeptide-producing bacteria, picocyanobacteria utilize an unprecedented mechanism of catalytic promiscuity for the production multiple structurally diverse lanthipeptides using a …

Community Dynamics of Freshwater Picocyanobacteria and Development and Application of HIP 1 PCR (Cyanobacterial Typing Technique).
… understanding of the diversity of a freshwater picocyanobacterial community. The HIP 1 PCR typing technique was developed and applied to 506 isolates of picocyanobacteria from a field study on Esthwaite Water in 2000. This study has demonstrated that genetic diversity existed within the …

Adaptive Mechanisms of an Estuarine Synechococcus based on Genomics, Transcriptomics, and Proteomics
Picocyanobacteria are important phytoplankton and primary producers in the ocean. Although extensive work has been conducted for picocyanobacteria (i.e. Synechococcus and Prochlorococcus) in coastal and oceanic waters, little is known about those found in estuaries like the Chesapeake Bay. …

Characterizing the ecology of coral reef microorganisms across different scales within the Caribbean
… concentrations, and higher abundances of picocyanobacteria compared to less protected reef-systems within Los Canarreos, Cuba and the Florida Keys, U.S.A and seawater microbial communities collected from each reef-system were influenced by hydrogeography and environmental gradients. …

Iron and Prochlorococcus
… strains. We then tested the iron physiology of picocyanobacteria in the field and found that Synechococcus is iron-stressed in samples where Prochlorococcus is not. Finally, we propose a method to measure how iron stress in Prochlorococcus changes over natural gradients of iron in the …

Host/virus interactions in the marine cyanobacterium prochlorococcus
… production in the oceans is performed by the picocyanobacteria Prochlorococcus and Synechococcus. The viruses ('cyanophages') that infect these cyanobacteria are unusual in that their genomes contain a large suite of orthologs to host metabolic genes. These orthologs, known as 'auxiliary …

Toxic cyanobacteria, cyanotoxins and drinking water production in Ghana: implications to human health
… in counting chambers. The biomass of picocyanobacteria was determined by epifluorescence microscopy after staining with DAPI. Extraction, purification and concentration of dissolved microcystins were done using the Solid Phase Extraction method. Identification of microcystins was done …
