Figure 2From: Rice bacterial blight pathogen Xanthomonas oryzae pv. oryzae produces multiple DSF-family signals in regulation of virulence factor productionXoo produces multiple DSF-family signals. (A) HPLC analysis of the active fractions after flash column chromatography. (B) The compounds in fractions a, b, and c showed strong DSF-like activity. (C) Chemical structures of the compounds in fractions a, b, and c as confirmed by ESI-MS and NMR analysis.Back to article page
