​​The primary objective of the research is to investigate the biochemical basis of inducible defense responses in crop plants towards pathogenic organisms to be able to manipulate the process to enhance natural disease resistance and to induce crop protection through measures that are benign to the environment. The focus of the research is on plant and microbial biochemistry, especially with regard to the complex plant : microbe interactions between plants and their pathogens that might lead to either disease or resistance depending on the perception capacity of the plant. The induction of defense-related genes and the immunization of plants against diseases that result in induced or acquired resistance are investigated. The aim is to develop novel strategies for crop protection, to complement traditional plant breeding efforts and to reduce the expense and environmental costs of reliance on conventional pesticide treatments.
