    The cyanobacterial circadian clock follows midday in vivo and in vitro

    Eugene Leypunskiy et al.
    The cyanobacterial core clock tracks midday regardless of day length, which can be understood in terms of a model for how the environment alters the clock limit cycle.

    Cyanobacteria use micro-optics to sense light direction

    Nils Schuergers et al.
    The cells of a cyanobacterium act as spherical micro-lenses, allowing the cell to see a light source and move towards it.

    Systems analysis of the CO2 concentrating mechanism in cyanobacteria

    Niall M Mangan, Michael P Brenner
    Systems level modeling of cyanobacterial mechanism for concentrating carbon dioxide shows optimal organization and enzymatic activity for enhanced carbon fixation.

    Natural changes in light interact with circadian regulation at promoters to control gene expression in cyanobacteria

    Joseph Robert Piechura et al.
    Cyanobacteria cope with both predictable day/night changes and natural fluctuations in light during the day by adjusting the expression dynamics of circadian-clock-controlled genes via a network of transcriptional regulators.

    The human gut and groundwater harbor non-photosynthetic bacteria belonging to a new candidate phylum sibling to Cyanobacteria

    Sara C Di Rienzi et al.
    Melainabacteria, a candidate phylum related to Cyanobacteria, has been identified in gut and sediment samples by genomic analysis.

    Crystal structures of virus-like photosystem I complexes from the mesophilic cyanobacterium Synechocystis PCC 6803

    Yuval Mazor et al.
    The structure of the photosystem I (PSI) complex from Synechocystis is determined, and reaction center subunits engineered to resemble a viral PSI are found to promote promiscuous electron acceptor properties.

    Switching of metabolic programs in response to light availability is an essential function of the cyanobacterial circadian output pathway

    Anna M Puszynska, Erin K O'Shea
    The circadian clock of Synechococcus elongatus PCC7942 schedules the activity of the transcription factor RpaA, which controls key events in carbon metabolism that contribute to cell fitness in conditions mimicking the natural environment.
