A maximum-likelihood tree generated from rps3 (rpsC) sequences.
Each major lineage detected in this study is highlighted in a different color. Colored circles below each name indicate which of the examined functions were observed in MAGs belonging to each lineage. Gray circles at the end of branches indicate lineages observed in this study. In the lower portion of the figure, panels depict the frequency with which the putatively encoded functions occurred across MAGs belonging to the detected linages. For example, AioA is found exclusively in MAGs belonging to the Alphaproteobacteria.
