| Zusammenfassung: | Abiotic and biotic disturbances induce gene expression level changes that can be measured and potentially be used for the detection of early stress symptoms in planta. If differentially regulated as response to a specific stress, these genes may be used as indicators allowing discrimination of its original inducer. For biotic stresses, examples of such specific indicators are resistance genes of resistant plant varieties functioning as specific receptors of pathogen effectors. In compatible plant species disease-specific genes were identified for instance as so-called susceptibility genes – i.e., genes that are targets of pathogen effectors making the plant accessible for the pathogen. In our study we aimed at identifying differentially-regulated genes that are specifically induced by one pathogen but not by others. In disease-comparative studies in tomato leaves, we identified 68 genes specifically regulated by either Botrytis cinerea or Phytophthora infestans at 24 hours post inoculation. These genes are not differentially expressed in leaves infected with Oidium neolycopersici. Following single-drop infections, we further investigated the spatial expression patterns of B. cinerea-upregulated genes throughout healthy leaf tissue. At 24 hpi the expression of two out of four upregulated genes did not vary significantly between sampling and infection location on the same tomato compound leaf indicating a leaf-systemic pathogen induced regulation. |
