Indole‐3‐acetic acid production by Xanthomonas strains pathogenic to citrus was analyzed by reversed‐phase high‐performance liquid chromatography, thin‐layer chromatography, UV spectroscopy and gas chromatography‐mass spectrometry, and quantified by high‐performance liquid chromatography with fluorescence detection. Amounts of auxin produced by Xanthomonas strains were low when compared with indole‐3‐acetic acid biosynthesis by other bacteria. In three different experiments it was shown that the addition of plant leaf extracts to bacterial cultures increased indole‐3‐acetic acid biosynthesis by Xanthomonas axonopodis pv. citri 223.
