Regulation of eal by RpfF and DSF. (A) Relative expression of eal in the wild-type strain and the rpfF mutant of X. fastidiosa after 7 days of growth, during which DSF is expected to accumulate. (B) Relative expression of eal in wild-type cells after 1 day of growth (young culture), during which DSF had not yet accumulated, and after 7 days of growth (old culture), during which DSF is expected to have accumulated. The vertical bars represent the standard deviations of the means (n = 7 for panel A and n = 5 for panel B).
