   Figure  S3:  (A)  Correlation  of  number  of  operons  and  fraction  of  operonic  genes  with   genome   size   across   cyanobacterial   strains.   (B)   Clade-­‐wise   distribution   of  fraction  of  operonic  genes  in  cyanobacteria.      

   Figure  S4:  The  box  plots  show  the  distribution  of  correlation  between  gene  expression  of  known  operonic  gene  pairs  of  Synechococcus  elongatus  PCC  7942.  The  operons  have  been  obtained  from  the  work  of  Vijayan  et  al.  (Vijayan  et  al.  2011)
