Fig. 3.

The taxonomic basis of bacterial and viral aerosolization. Genome-based phylogenetic trees from read-based annotations trimmed of genomes with low spatial coverage: a 76 bacterial genomes and b 30 viral genomes. Aerosolization factors (AF), A:B and A:S, on different days are indicated (Blue = Diminished aerosolization; Yellow = Neutral aerosolization; Red = Enhanced aerosolization). Blanks indicate samples below threshold limits. a Bacteria class is indicated on outer ring to further indicate species and shading of species names indicate orders of interest. In b, the outer ring denotes viral family and shading indicates presence or lack of a viral envelope. i, ii, and iii indicate genomes with aerosolization patterns that differ from their closest relatives.
