Complex Interplay of Future Climate Levels of CO2, Ozone and Temperature on Susceptibility to Fungal Diseases in Barley

Bolette Lind Mikkelsen

Abstract

Climate change will modify the environmental growth conditions for plants, and consequently also their physiology and susceptibility to diseases. However, there is a lack of experimental studies on the effect of climate change on plant diseases, which include several climatic factors in order to simulate realistic growth conditions. In this PhD thesis, the complex interplay of elevated CO2, temperature and ozone on the susceptibility of barley to the biotrophic powdery mildew fungus (Blumeria graminis f.sp. hordei) and the hemibiotrophic spot blotch fungus (Bipolaris sorokiniana) was revealed. The underlying mechanisms hereof was examined by studying changes in photosynthesis, accumulation of secondary metabolites and global gene expression after B. graminis attack
