Preliminary C1 domain tree. A preliminary phylogenetic tree for C1, including only sequences with E ≤ 10−10, contains very few overall taxa. The tree contains only members of the Chloroflexi, members of the Nitrospirae, and Nitrospina gracilis; the sampling depth does not recover an outgroup for these sister groups. Support for bipartitions is indicated with the following color scheme: Strong support with both values ≥90 (black); weak support with both values ≤50 (white); intermediate support with one or both values between 50 and 90 (gray); conflicting support, with one value ≤50 and the other ≥90 (gray)
