Phylum level abundance profiles using 16S rRNA sequence classifications. Columns reflect the percentage of 16S rRNA sequences assigned to each phylum using the RDP classifier. All ws samples show a more even representation of Proteobacteria, Firmicutes, Actinobacteria, and Verrucomicrobia, as well as a higher representation of sequences that could not be assigned to any phylum (with a confidence threshold of 80%). We also observe a spike in Firmicutes abundance in a surface water-treated phyllosphere sample 4 (ps4). In all other samples, Proteobacteria 16S rRNA sequences tend to dominate the profiles.
