Resistance biology

Last changed: 26 April 2017



Our research is focused on how plants defend themselves against oomycetes and fungi. We study biochemical components of plant defence and the interactions with pathogens and try to identify resistance factors that can be used in future breeding for disease resistance and in developing methods for induced resistance by applying non-toxic inducing agents. The goal is to reduce the dependence on chemical fungicides.


We work mainly in the following fields:

Resistance mechanisms

Potato late blight, caused by Phytophthora infestans, is one of the most devistating pathogens in Sweden and worldwide. In Swedish agriculture almost half of all fungicides are used against this pathogen. To reduce the dependence on fungicides there is a great need for novel resistance. In several projects we work with resistance against this disease and are also involved in breeding of potatoes. The resistance mechanisms are ilucidated by identification of proteins involved in the interaction between this oomycete and the plant (proteomics and phosphoproteomics) and by studies of the infection process with microscopical and molecular methods.

Induced resistance

To get efficient plant protection strategies different methods has to be integrated. We do applied experiments with induced resistance, in greeenhouse and field, combined with classical fungicides.

Pathology – other diseases

We study plant resistance and pathogen populations in various plants and diseases, such as Alternaria on potato, Colletotrichum on coffee and some pathogens on cereals.
