As well as leading the Integrated Plant Protection Unit, I also lead my own research group, the Plant Pathology Lab. My own research group focuses on the molecular and genetic determinants of disease in oomycete and fungal plant pathogens in combination with molecular analysis of interactions between microbial biocontrol agents and their prey along with the soil rhizosphere microbiome communities. We combine these mechanistic studies with applied research, testing combinations of biocontrol agents, plant probiotics and plant resistance inducers and disease modeling strategies, for effective disease control. This information is used to develop more durable, environmentally sustainable integrated pest management (IPM) strategies for plant diseases that are applicable both for large scale Swedish farmers and for smallholder farmers in Western Africa.
We focus on both horticultural and agricultural crops, including potato, sugarbeet and cocoa.
Course leader: BI1267 (MSc) Integrated Pest Management in Sustainable Production Systems.
Work in my group, is currently funded by the Swedish Research Council Formas, Swedish Research Council VR, The EU (Marie Skłodowska-Curie European Training Network PROTECTA (H2020-MSCA-ITN-2017-766048) and H2020 program grant Organic Plus, SLU Grogrund, The Crafoord Foundation and the Carl Tryggers Foundation, and is focused around the following projects:
1. Pathogen-Informed Resisance To Oomycete Diseases in Ecosystems, Agriculture and Aquaculture (PROTECTA)
In this H2020-MSCA-ITN EU project we are working across Europe to understand effector biology, host resistance, biological control and management strategies for oomycete diseases across different sectors. 15 early stage researchers (PhD students) are involved in the project from diverse European labs. read more at the project website: www.protecta-itn.eu
2. The expression and evolution of Phytophthora infestans effectors in potato fields and implications for disease control.
In this project we are using an eco-evolutionary approach to understand how P. infestans adapts effector expression to avoid host recognition within an agricultural field setting. We are using a combination of genomic, genetic and evolutionary methods to study this.
3. Exploiting the biological activity, and effector repertoire, of the mycoparasitic oomycete Pythium oligandrum for disease control.
In this project we are interested in further developing P. oligandrum for use as a BCA. To do this, we study the biology of P. oligandrum, the pathogenicity determinants produced during host colonization and the survival and adaptation of this BCA in field conditions. We also study the interaction between the BCA and the pathobiome (the disease causing microbial community) and the natural potato rhizosphere soil microbial communities (the microbiome) to understand the impact and interactions of this BCA with other microbes to improve potato and soil health in the field.
4. Breeding for Biologicals: Plant breeding for optimized interactions between crops and biologicals to enhance pest management and production with reduced agrochemical use
I this project we aim to (1) identify the plant genes that are needed for successful promotion by microorganisms (biological control agents) and (2) develop optimal methodologies to implement the new knowledge into breeding and to (3) optimize methodologies (e.g., seed- and leaf applications) needed for utilising the breeding benefits in agriculture.
5. Towards sustainable cocoa production in Western Africa: epidemiology and control of cooca black pod disease and cocoa swollen shoot virus
In this project we are working with smallholder farmers to study the epidemiology and practical development of IPM control strategies for cocoa diseases in Sierre Leone, Togo and Nigeria.
6. Comparative genomics and transcriptomics of diverse and understudied oomycetes including sequencing the genomes and transcriptomes of:
◦ The Mycoparasites Pythium oligandrum and Pythium periplocum
◦ The entomopathogenic oomycete BCA Lagenidium giganteum
◦ The emerging food security threat, Phytophthora colocasiae (Taro leaf blight)
7. Comparative molecular analysis of the early blight fungus (Alternaria solani) and the late blight oomycete (Phytophthora infestans) and identification of core effectors as new targets for resistance breeding strategies.
In this project, we are studying competition or synergism between multiple pathogens on the same host plant and the implications of these interactions for disease control.
8. Organic Plus
In this H2020 EU funded project, led by the University of Coventry, UK, we are working towards development and testing of biological control solutions for organic potato farming in Europe. Read more at the project website: Organic-plus.net
We have a large international collaboration network.
Please see www.protecta-itn.eu and www.organic-plus.net for a list of collaborators in those EU projects.
Industry collaborations include sugar beet breeding company Maribohilleshög AB and the potato starch producers association of Sweden, Lyckeby Starch AB as well as cereal breeding company Lantmännen AB.
We also collaborate with the IITA (Nigeria), and Njala University (Sierra Leone) in our cocoa black pod project.
