Abstract

We have demonstrated that the O-antigen of bacterial cell wall lipopolysaccharide from certain species of Pseudomonas mimics the effect of the bacterium from which it was isolated in the induction of systemic resistance of crops to pathogens. The structures of the O-antigens from Pseudomonas strains inducing differential resistance in crops will be determined using state-of-the- art mass spectrometric techniques and classical carbohydrate chemistry in order to identify those structural elements of the ligands responsible for the difference in activities. The minimal bioactive structure will be identified following partial degradation and chromatographic isolation, making it uniquely possible to study the mechanism of this biocontrol process.
