In this study, the microbial ecology, potential environmental adaptive mechanisms, and the potential
evolutionary interlinking of genes between bacterial, archaeal and viral lineages in Guerrero Negro
(GN) microbial mat were investigated using metagenomic sequencing across a vertical transect at
millimeter scale. The community composition based on unique genes comprised bacteria (98.01%),
archaea (1.81%), eukarya (0.07%) and viruses (0.11%). A gene-focused analysis of bacteria archaea,
eukarya and viruses showed a vertical partition of the community. The greatest coverages of genes
of bacteria and eukarya were detected in first layers, while the highest coverages of genes of archaea
and viruses were found in deeper layers. Many genes potentially related to adaptation to the local
environment were detected, such as UV radiation, multidrug resistance, oxidative stress, heavy
metals, salinity and desiccation. Those genes were found in bacterial, archaeal and viral lineages with
6477, 44, and 1 genes, respectively. The evolutionary histories of those genes were studied using
phylogenetic analysis, showing an interlinking between domains in GN mat.
