FIG 4

(A) 2(Z)-Tetradecanoic acid dose-dependent increase in biofilm formation in the liquid-air interface of a wild-type X. fastidiosa strain grown in a shaken broth culture. Biomass attached to the glass wall of a culture tube was measured after 24 to 48 h by crystal violet staining. (B) qPCR analysis of the relative levels of expression of hxfB in X. fastidiosa wild-type cells, in a shaken broth culture in the presence of 10 µM 2(Z)-tetradecanoic acid or MeOH only. RNA was extracted after 24 to 48 h; rpsO and rpoD served as endogenous controls.
