LuxR induction in solid agar cultures.

The leftmost image shows the layout used to determine induction distance across agar. Sender bacteria were spotted in the center. Bacteria transformed with Control-EGFP (GFP), receiver negative (NR), or LuxR receiver (R) plasmids were spotted within rectangular areas that radiated away from the center. Induction distance in centimeters is shown for each of the ten Senders tested.
