Amplified phage densities in the six-passage experiment

Phage densities in plaque forming units (PFUs) after amplification for each passage in vitro and in vivo. “PFUperml_limitadjusted” has been calculated as the PFU per ml culture (in vitro lines) or PFU per 1 mm2 tissue (in planta lines), and any values below the limit of detection were recorded as being at that limit (as a conservative estimate of density). “Line” is the evolution line identifier, “Treatment” is passaging treatment, “Environment” is the passaging environment, and “Week” is the passage number. Results are presented in Supplementary Figure 1.
