Fig. 5From: The phytopathogen Xanthomonas campestris scavenges hydroxycinnamic acids in planta via the hca cluster to increase virulence on its host plantThe effect of hydroxycinnamoyl-CoA accumulation on hca transcription in Xcc. a Phca-dependent GUS activity of three reporter strains on NYG agar medium supplemented with 50 μM HCAs. b Phca-dependent GUS activity of two reporter strains in NYG liquid medium supplemented with 50–200 μM HCAs. Data shown are the averages of three independent experiments with standard deviations. Values significantly different from non-HCA treatment are indicated by one (P < 0.05) asteriskBack to article page
