Septoria tritici blotch (STB), caused by the hemibiotrophic fungal pathogen Zymoseptoria tritici, is one of the most devasting foliar diseases of wheat in the European Union. We used an untargeted approach to investigate the extent of metabolic changes to elucidate the poorly-understood physiology of the wheat-Septoria interaction. Metabolomic profiling of leaf extracts by liquid chromatography mass spectrometry (UHPLC-ESI-QTOF-MS) of semi-polar extracts was used to evaluate metabolic reprogramming in 2 cultivars of wheat (one resistant and one susceptible) at 3 time points post inoculation with a suspension of Z. tritici spores. Considering genotype selection, multivariate analyses showed that differences in metabolic signatures during disease progression has the potential to enable the identification of metabolic markers for wheat-Septoria interaction.
