Dynamics of bacterial growth and Pel production.A, growth curves of Dickeya dadantii in M63 minimal medium supplemented with glucose (dashed) or glucose+PGA (solid). The transition time is indicated by a gray vertical dashed line and is used as a reference timepoint throughout the article. B, total Pel enzymatic activity measured in the extracellular space along bacterial growth in glucose (dashed) or glucose+PGA (solid) media. PGA induces Pel activity by a factor of around 30. C, pelD and pelE expression measured by qRT-PCR along bacterial growth in glucose+PGA medium (green and red solid lines, respectively). pelE expression levels are also shown in the absence of PGA (dashed red line). All the error bars represent 95% confidence intervals obtained from two biological replicates. Pel, endo-pectate lyase; PGA, polygalacturonate.
