We study biological functions of secondary metabolites of plant and fungi. In projects with publication output between Jan. and Aug. 2019 we investigated fungal defense metabolites (Xu et al. 2019), the effect of agroforestry on soil microbiome and plant/pathogen interactions (Beule et al., 2019a and 2019b), exudates of plant root and hairy roots (Kareem et al. 2019), metabolic transformations of mycotoxins (Borzekowski et al. 2019) and applied topics in mycotoxin research (Ezekiel et al. 2019; Balendres et al. 2019). Our main research tools are gene expression analysis (RNAseq and RT qPCR), gene disruption in fungi, DNA-based analysis of microbial communities (amplicon sequencing by NGS), chemical analyses, bioassays, and nontargeted metabolic profiling.
