(A) Multidimensional scaling analysis based on taxonomic domains. Comparison of our results with previous published metagenome analysis from Atacama´s desert halite rock samples [8,9]. (B) Bacteria and Archaea, and (C) Viruses. Crusts 1–3 represent the metagenomes analyzed by the authors of [9], while Endolithic 1 corresponds to metagenome analyzed by the authors of [8]. Endolithic 2 represents the halite metagenome analyzed in this work. Metagenome identifies as Hypolithic corresponds with the data obtained by the authors of [22]. Table S1 summarizes the characteristic of metagenomic data identified as Hypersaline 1–5 and Desert soil 1–4.
