FIG. 2.

Growth (filled diamonds) and competence development (open diamonds) kinetics of A. baylyi strain BD413(pBAB2) inoculated onto leaf surfaces (A) or ground leaf discs (B) of wild-type tobacco plants and incubated for 7 days or inoculated into LBm broth and grown for 40 h (C). Competence development is expressed as the log number of transformation frequencies (transformants/recipients) determined after exposure of the bacterial suspensions recovered from leaf tissues to the plasmid pCEA in vitro.
