Institut für Resistenzforschung und Stresstoleranz
With the planned project, the expertise of the three participating institutes PB, RS and A is to be combined in a meaningful way in order to identify and implement necessary adaptation measures to future climatic and environmental conditions with new findings on the influence of increasing CO2 concentrations on the extent and intensity of the infection of wheat with brown rust (Puccinia recondita) and ear fusarium (Fusarium graminearum/ Fusarium culmorum), the biology of the pathogens, plant development and the corresponding development of resistance in winter wheat. The project will contribute to define new - so far unknown - resistance traits for future climatic conditions and to identify their genetic determinants in order to develop approaches for new control strategies. In the field of resistance research and stress tolerance, the (increasing) CO2 content has not yet been considered with regard to its influence on infection by important fungal pathogens such as rusts and Fusarium. Since numerous studies have observed an influence on the course of infection or the expression of symptoms, the course of brown rust and Fusarium infections will be examined as examples. These two pathogens are chosen because they are of high economic importance, and each represents a representative of pathogens that infect the leaf ("source") as well as the ear ("sink"). In addition, Fusarium pathogens can have a significant impact on crop recovery due to their potency to produce harmful mycotoxins (e.g., deoxynivalenol).
