FIG 4.

Relative abundances of 16S rRNA gene sequences related to Pseudovibrio in different environmental sources. Environmental sources represented by fewer than three samples screened by the IMNGS platform are summarized as “others” for better readability. Relative abundance values of ≤0.01% are not plotted. Colors correspond to environmental source. To avoid overrepresentation of data sets with hits from two or more Pseudovibrio lineages, only the maximum relative abundance value is displayed.
