Fig. 6. Maximum-likelihood phylogenetic tree of comammox Nitrospira sp. amoA gene sequences retrieved from EAA soil plots 1 through 5, and Everglades wetland soil SRS3.

The tree was calculated using RAxML algorithm with GTRGAMMA-25 rate distribution model and rapid hill climbing algorithm based on 383 nucleotide positions. Heat map shows relative abundance of each OTU within each soil (in %). Sequences with more than 94% sequence similarity on nucleotide level were grouped into single OTUs. The total number of sequences within a given OTU, if more than one, is indicated in each tree leaf. Labels on the right refer to comammox amoA clade A and B.
