1. The genetics of antibiotic production and the role of antibiotics in biological control of Erwinia amylovora by Erwinia herbicola
Sammanfattning : Erwinia herbicola is an epiphyte of apple and pear with potential as a biocontrol agent of Erwinia amylovora, which causes fire blight. This research aimed to assess the relative role of antibiotics produced by E. herbicola, Eh318 as a mechanistic basis for biocontrol. LÄS MER
2. Biological control of plant-parasitic nematodes by the fungus Clonostachys rosea
Sammanfattning : Plant diseases caused by plant-parasitic nematodes are serious constraints to sustainable crop production due to high yield losses, the persistent nature of these nematodes and a lack of efficient control methods. Biological control is a promising approach to reduce plant diseases caused by nematodes. LÄS MER
3. Drivers of soil fungal communities in boreal forests : feedbacks on soil fertility and decomposition
Sammanfattning : Boreal forests harbour diverse fungal communities with decisive roles in decomposition and plant nutrition. Difficulties in studying soil fungi have limited knowledge about how fungal communities are shaped. LÄS MER
4. Diversity and functional potential of fungal communities in Arctic and boreal freshwaters
Sammanfattning : Fungi are important decomposers of the organic matter (OM) in terrestrial environments, but there is limited knowledge about their ecological roles in aquatic ecosystems. This thesis applies a variety of molecular techniques (e.g. LÄS MER
5. Understanding virulence of Heterobasidion annosum s.l., a root rot pathogen of conifers
Sammanfattning : Heterobasidion annosum sensu lato (s.l.) species are destructive pathogens causing root and butt rot in conifers. The species complex consists of five species: H. LÄS MER
