The research topics of our lab in the last years included fungal chemical defense against predators, soil microbiome and plant health in agroforestry, metabolic diversity of hairy roots, metabolic transformations of mycotoxins, and applied issues related to fungal infection and mycotoxin contamination of grain crops. Our tools are gene expression analysis (RNAseq and RT qPCR), gene disruption in fungi, analysis of microbial communities by next generation sequencing, chemical analyses including nontargeted metabolic profiling, and bioassays.
