a
Abundance of putative fatty acid-derived molecular ions resolved by electrospray ionization-mass spectrometry (ESI-MS) analysis of DSF-containing culture extracts of P. agglomerans and X. fastidiosa strains.
b
The m/z values and chemical formulas are of ionized molecules.
c
Abundance of putative fatty acid-derived molecular ions (in relative arbitrary counts) resolved by ESI-MS analysis of DSF-containing culture extracts of P. agglomerans expressing vector only or expressing XfRpfF (XfRpfF+) and three X. fastidiosa strains, the wild-type X. fastidiosa strain and rpfF and rpfC deletion mutant strains.
