Daniel Hofius' Lab - Plant-Pathogen Interactions

Last changed: 24 November 2021

We have a general interest in understanding the molecular and genetic mechanisms by which plants interact with and defend themselves against pathogens.

We focus on two evolutionary conserved biological processes with fundamental roles in both organismal health and pathological circumstances: Autophagy (Greek for “self-eating”) representing a major cellular degradation and renewal system, and programmed cell death (PCD) referring to different routes of genetically controlled cell suicide. We particularly aim at deciphering their functions, regulation, and interplay in plant immunity and disease.

Our current research addresses the following themes:

  • Role of autophagy in host immunity and pathogen-triggered cell death
  • Pathogen modulation and pro-microbial functions of autophagy
  • Crosstalk of autophagy with the ubiquitin-proteasome system
  • Membrane trafficking and vacuole functions in autophagy and cell death
  • Epigenetic regulation of plant immunity and cell death
  • Manipulation of autophagy for improved pathogen and stress resistance

We apply state-of-the-art genetic, proteomic, biochemical and cell biological approaches, and work with different bacterial, viral, and oomycete/fungal pathogens mainly in the model plants Arabidopsis thaliana and Nicotiana benthamiana. In addition, we strive to translate our findings into crop plants like potato and tomato.

We are located at the Uppsala BioCenter and are part of the Linnéan Center for Plant Biology in Uppsala, the Nordic Autophagy Network/Society and the Transautophagy COST action. Our research is funded by the Swedish University of Agricultural Sciences (SLU), Knut-and-Alice Wallenberg (KAW) Foundation (Epifate project), Swedish Research Councils VR and FORMAS; Carl Tryggers Stiftelse (CTS), and the Federation of European Biochemical Societies (FEBS).
