mcrA phylogenetic affiliation and abundance per sample. The RAxML tree was constructed using 37 amino acid sequences. The gene affiliation was inferred from the best BLASTP hit. Bolded names represent mcrA present in reconstructed genomes. For the heat map, the mcrA-containing contig RPKM values were used as input. The statistical significance of hierarchical clustering branches is indicated by green stars (pvclust, approximately unbiased p < 0.05)
