The promoter activities of <i>hrpS, hrpL, hrpA</i> and <i>hrpN</i> of <i>Dickeya dadantii</i> 3937 (Ech3937) and <i>rsmB</i> mutant Ech148 grown in minimum medium.

aThe promoter activities were compared at 6 and 12 h of bacterial growth. 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 are a representative of three experiments with similar results. Three replicates were used in this experiment. The value is present as the average of three replicates with standard deviation (SD).
