Anders Hafrén Lab – Plant-Virus Interactions

Last changed: 20 January 2022

Our lab has a broad focus on how plants interact at the molecular, cellular and organismal level with a diverse range of viruses in disease and defense.

We have a particular interest in how selected plant resilience pathways are integrated into viral disease processes. These include mRNA and virus regulation by RNA granules termed processing bodies and stress granules, RNA silencing, the ubiquitin-proteasome system and autophagy. In the image upper-left corner there is a non-infected Arabidopsis thaliana (our main plant model), together with 12 different viral species/strains that are being studied in the lab. We believe that comparative virology will be key to many intriguing discoveries. By another approach, we also try to understand virus disease by utilizing Arabidopsis natural genetic variation including genome-wide association studies for unbiased identification of novel plant genes working in viral disease responses.
