FIGURE 8

The expression of the ipdc gene of Serratia plymuthica A153 is induced in the presence of aromatic amino acids. Shown is the transcription of the ipdc (P ipdc ::lacZ; pMAMV302) promoter fusion in S. plymuthica A153. β‐Galactosidase activity was determined after 24 h of growth in minimal medium (MM) with 15 mM glucose at 30°C in the presence and absence of 1 mM L‐Trp (L‐Tryptophan), L‐Phe (L‐Phenylalanine), L‐Tyr (L‐Tyrosine) or IAA (indole‐3‐acetic acid). Data are the means and standard deviations of three biological replicates. Differences between bars with the same letter are not statistically significant (p‐value < 0.01; by Student's t‐test).
