Description of research and teaching


Plant health is an increasingly important issue as sufficient food security is endangered by the global climate change and growing population of the world. The research in the group focuses on the molecular mechanisms underlying Potato virus A (PVA) infection. PVA is a member of genus Potyvirus, which is economically the most devastating group of plant RNA viruses. Understanding the different stages of virus infection is a prerequisite for being able to prevent infections. The research in the group is carried out with the advanced techniques of biochemistry, and molecular and cell biology. The aims of  our research are:

 1) to produce novel information of the various stages of the virus multiplication cycle (protein synthesis, RNA replication, virus movement, encapsidation), and how these functions are localized and coordinated within the infected cells.

2) to tackle the disease problem caused by the genus Potyvirus, which is economically the most devastating group of plant viruses. Host factors involved in viral multiplication represent potential targets for virus control. Their identification and functional characterization is one of the major frontiers in virus research.

3) to follow viruses present on barley and oat field in Southern Finland and to study the impact of undersown cover crop plant species diversity on barley / oat viruses.  

4) to exploit viruses in nanobiotechnology applications.


I am responsible for organizing the teaching of plant pathology in Bachelor's and Master's programmes in Agricultural Sciences, in Plant Production Sciences study track. The MSc plant pathology teaching consists of courses in Fungal Plant Pathogens, Plant Pathogenic Bacteria, Plant Virology, Epidemiology and Ecology of Plant Pathogens and Plant-Microbe Interactions. The students get also training in the plant pathology research groups. 

I have been an organizer and teacher on several post graduate courses on plant virology, plant-pathogen co-evolution and heterologous protein production in plants. Several doctoral students have graduated under my supervision.
