Cladograms of twenty Microcystis strains based on A- phylogenetic analysis using RAxML inference on concatenated alignments of six housekeeping genes (ftsZ, glnA, gltX, pgi, recA, and tpi), ribosomal protein S3, global nitrogen regulator (ntcA), and phycocyanin subunit B (cpcB) genes and B- parsimony search of presence/absence of flexible genes within each genome. SC = Subclade as assigned by Humbert et al. (2013) [31], red lines indicate where phylogenetic assignments differ between trees A and B, *strains which are toxic based on the presence of the mcy gene operon.
