The phylogenetic tree of 51 cyanobacterial concatenated ribosomal proteins. The main topology is in agreement with earlier inferences of the phylogeny of this taxon with the 16s rRNA based on the GTR+G+I substitution model [7]. The tree is built using the Neighbor-Joining method and 1,000 re-samplings to calculate bootstrap values. A. platensis C1 was clustered together with other strains in the order Oscillatoriales and was clearly separated from related species in the order Nostocales. The conserved, concatenated ribosomal protein phylogenetic tree indicated the monophyly of this Arthrospira genus.
