Figure 1From: Insights into archaeal evolution and symbiosis from the genomes of a nanoarchaeon and its inferred crenarchaeal host from Obsidian Pool, Yellowstone National ParkMaximum likelihood of the Archaea based on SSU rRNA (872 sites) and the relationship of Nst1 and Acd1 with representative cultured and uncultured Archaea. The branch numbers indicate bootstrap support, shown only for major clades (* is <50%).Back to article page
