Lipopolysaccharide from Xanthomonas campestris induces defense-related gene expression in Brassica campestris.
Purified lipopolysaccharide (LPS) from Xanthomonas campestris pv. campestris induced accumulation of transcript for beta-1,3-glucanase in turnip at concentrations of 1 micrograms/ml. The lipid A-inner core structure was required for activity but the O-antigen had no role. We suggest that release of LPS in planta triggers expression of at least some defense-related genes.
