The role of horizontal gene transfer in the evolution of sensory systems in PCC 7942. Several proteins containing diguanylate cyclase and other domains involved in signal transduction mechanisms are predicted to be xenologs. Here we show a) a neighbor-joining tree reconstructed using the diguanylate-cyclase domain (86 sites, Poisson correction, 100 bootstrap replicates, branches with bootstraps below 50 are collapsed) from these proteins. Those proteins predicted to be xenologs are colored with red branches in the tree; b) domain structure of proteins following Pfam database [52].
