Directional RNA deep sequencing sheds new light on the transcriptional response of Anabaena sp strain PCC 7120 to combined-nitrogen deprivation [PDF]
, 2011 Background: Cyanobacteria are potential sources of renewable chemicals and biofuels and serve as model organisms for bacterial photosynthesis, nitrogen fixation, and responses to environmental changes. Anabaena (Nostoc) sp.

Paulinella chromatophora – rethinking the transition from endosymbiont to organelle
Acta Societatis Botanicorum Poloniae, 2014 Eukaryotes co-opted photosynthetic carbon fixation from prokaryotes by engulfing a cyanobacterium and stably integrating it as a photosynthetic organelle (plastid) in a process known as primary endosymbiosis.

Culturing the marine cyanobacterium Prochlorococcus [PDF]
Limnology and Oceanography: Methods, 2007 Prochlorococcus is the numerically dominant primary producer in open ocean ecosystems. Analysis of Prochlorococcus genome sequences from cultured isolates and ocean samples has broadened interest in studying this tiny cell, and efforts are underway to develop it into a model system for studying marine microbial ecology.

The Ability of Cyanobacterial Cells to Restore UV-B Radiation Induced Damage to Photosystem II is Influenced by Photolyase Dependent DNA Repair [PDF]
, 2013 Damage of DNA and Photosystem-II are among the most significant effects of UV-B irradiation in photosynthetic organisms. Both damaged DNA and Photosystem-II can be repaired, which represent important defense mechanisms against detrimental UV-B effects ...

Transformation of a filamentous cyanobacterium by electroporation [PDF]
Journal of Bacteriology, 1989 The filamentous cyanobacterium Anabaena sp. strain M131 was transformed with the shuttle vector pRL6 by electroporation. Optimum conditions for electroporation required relatively high field strengths with short time constants. Restriction significantly lowered the efficiency of transformation. A plasmid containing a single unmodified AvaII restriction

Population structure of an Antarctic aquatic cyanobacterium
Microbiome, 2022 AbstractBackgroundAce Lake is a marine-derived, stratified lake in the Vestfold Hills of East Antarctica with an upper oxic and lower anoxic zone. Cyanobacteria are known to reside throughout the water column. ASynechococcus-like species becomes the most abundant member in the upper sunlit waters during summer while persisting annually even in the ...
