Description: Das Projekt "Pflanzenbiotechnologie-Verbundvorhaben: Nutzung von Genen zur Erhöhung der Resistenz und Toleranz der Getreidewurzel gegenüber biotischem und abiotischem Stress (CEREAL-ROOTS)" wird vom Umweltbundesamt gefördert und von Universität Erlangen-Nürnberg, Department Biologie, Lehrstuhl für Biochemie durchgeführt. The focus and unique feature of this project is the investigation of the GRAMINEOUS ROOT. The consortium combines breeding, phytopathological and physiological expertise of the highest international standard, which, in a synergistic way, will enable to tackle the important questions of root stress biology with a present focus on enhancing root disease resistance and salt tolerance. Plant growth and development are entirely dependent on an intact root system, primarily ensuring water and mineral supply. Beside nutrient allocation, the plants health status is strongly influenced by the quality of the root - soil interface. Biotic and abiotic stresses affect efficient root operation and thus threaten biomass formation and yield. Hence, the consortium centers on complementary research strategies to identify and exploit genes that protect roots from biotic and abiotic stresses. Given the high risk of emergingdiseases due to atmospheric and soil temperature changes, one key issue of the proposal is the question how increasing abiotic stress may impinge on plant performance against emerging root pathogens. The specific goals of this proposal are: (1) Isolation of genes conferring resistance to root diseases. (2) Identification of genes conferring improved salt tolerance. (3) Elucidation of effects from saline soils on pathogen resistance mechanisms to identify genes that are protective in combined stress situations. Salt stress is known to cause significant transcriptional changes in roots. Some of these changes include genes associated with general stress responses. To validate the possible impact of increasing salinity on pathogen resistance, global transcript and metabolite profiles of barley varieties treated with i. salt, ii. a pathogen-associated fungal PAMP, iii. the root lesion nematode Pratylenchus, and iv. combinations thereof will be compared to identify differentially expressed genes which will functionally be validated in plant assays. Complementary, PIs will use a direct candidate approach: A functional group list for cereal chitin-binding related PRR with LysM domains will be completed based on rice genome and fragmentary information on other Gramineae, and validated in plant assays. In analogy PIs will select from literature genes associated with salt tolerance. Backcross lines and transgenic plants with improved performance under combined stresses will be validated under green house and field conditions and serve as base breeding material for commercialisation.
