Fig. 2: Microbial community composition of the microbial mats from Etang de Berre (EDB) and Salins du Lion (SL).

Intensity of the color in the heatmap is proportional to the relative proportion of each group in the pool of 16S rRNA reads recovered from the metagenomic dataset. Only lineages representing more than 1% of the reads in at least one sample were represented. Bacteroidetes lineages are represented in brown, Chloroflexi in dark gray, Cyanobacteria in cyan, Planctomycetes in ochre, Alphaproteobacteria in blue, Desulfobacterota in green, Gammaproteobacteria in orange and Verrucomicrobia in gray. The number of bins associated with each taxonomic group is indicated at the right. 94 additional bins were recovered from lineages representing less than 1% of the 16S rRNA reads.
