The expression of hrpA, hrpN, hrpL, and hrpS of Dickeya dadantii 3937 (Ech3937) in MM, MM supplemented with 0.1 mM OCA (MMOCA), and MM supplemented with 0.1 mM TCA (MMTCA).

aThe promoter activities were compared at 12 h of grown in the media. GFP intensity was determined on gated populations of bacterial cells by flow cytometry. GFP intensity was determined on gated populations (10,000-15,000 events) of bacterial cells by flow cytometry. The fluorescence intensities were collected, including average GFP fluorescence intensity of total bacterial cells (Total), average GFP fluorescence intensity of GFP expressing bacterial cells (GFP+), and the percentage of GFP expressing bacterial cells of the total bacterial cells (GFP+%).bValues (Mean Fluorescence Intensity) are a representative of at least 3 experiments with similar results. Three replicates were used in this experiment. The value is present as average of three replicates with standard deviation (SD).
