Expression profile of the hrpG promoter in both apoplast and xylem exudates. Induction of the hrpG promoter in bacteria grown in cell-free plant exudates. A representative result using three biological replicates is shown. Promoter output is presented as relative luminescence units (R.L.U) produced by the lux reporter corrected by cell density estimated by OD600. Error bars indicate standard deviations.
