Phylogenetic analyses of C-domains showing groups according to gene cluster and position/function. The C-domain phylogeny was constructed using Bayesian inference with gamma distribution, 4 mill generations tree sampling every 100 generations and removal of the first 3000. The topologies generated using NJ (MEGA 3.1) and ML (RAxML) analyses show near identical branching patterns-only minor differences are seen within the Apd group. Bayesian posterior probability, NJ (1000 bootstrap values) and ML (100 trees) above 50% are shown. CpRev protein substitution model was used in the Bayesian and ML analyses. Genus origin is shown with first letter abbreviations (P = Planktothrix, M = Microcystis, A = Anabaena and N = Nostoc), and the C-domains are labeled in numerical order according to direction of transcription (i.e. seven oci, seven mcn and six apd C-domains). Corresponding Oci C domains group together, except for C2 situated downstream of the 205-E-domain. C1–C4 apd, nos and ncp C-domains do not group according to function
