Abstract: 

We have analysed the phenomenon of systemically activated resistance (SAR) in the interaction of the powdery mildew fungus (Erysiphe graminis) with the respective hosts, wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.). One aspect of the work concerns the identification and assessment of molecular markers for SAR, i.e. gene products that accumulate with a certain kinetics after the onset of SAR. Such markers might be a valuable tool for the identification of new resistance inducing compounds.
As one prerequisite for the assessment of a molecular marker we have analysed the cytological events on barley leaves and coleoptiles following treatment with a resistance inducing compound. This study was aimed at the definition of cytological criteria for SAR.
Another rational way for identification and assessment of a potential molecular marker is the use of plant genotypes with altered sensitivity for chemical resistance inducers. We discuss here a preliminary study of the expression of PR genes in such genotypes.
