    • Circadian Gene Expression in Cyanobacteria 

      Vijayan, Vikram (2013-03-18)
      Cyanobacteria are photosynthetic prokaryotes that live in aquatic environments. The cyanobacterium Synechococcus elongatus PCC 7942, (hereafter S. elongatus) coordinates its day and night behaviors via a circadian clock. ...

    • A High Resolution Map of a Cyanobacterial Transcriptome 

      Vijayan, Vikram; Jain, Isha Himani; O'Shea, Erin K (BioMed Central, 2012)
      Background: Previous molecular and mechanistic studies have identified several principles of prokaryotic transcription, but less is known about the global transcriptional architecture of bacterial genomes. Here we perform ...

    • Oscillations in Supercoiling Drive Circadian Gene Expression in Cyanobacteria 

      Vijayan, Vikram; Zuzow, Rick; O'Shea, Erin K (National Academy of Sciences, 2009)
      The cyanobacterium Synechococcus elongatus PCC 7942 exhibits oscillations in mRNA transcript abundance with 24-h periodicity under continuous light conditions. The mechanism underlying these oscillations remains elusive—neither ...

    • Sequence Determinants of Circadian Gene Expression Phase in Cyanobacteria 

      Vijayan, Vikram; O'Shea, Erin K. (American Society for Microbiology, 2012)
      The cyanobacterium Synechococcus elongatus PCC 7942 exhibits global biphasic circadian oscillations in gene expression under constant-light conditions. Class I genes are maximally expressed in the subjective dusk, whereas ...
