  • a Migration distances in 0.25% agar medium relative to those of wild-type V. fischeri. The data are from a representative experiment, which was repeated with the same outcome. Measurements are accurate to within approximately 10%. Migration diameters were determined in a rich SWT medium or in a minimal medium with either CAA or NAG as the sole carbon source.

  • b BD, below detection (no migration observed).
