Abstract
The methods described in this chapter were developed in order to produce transgenic plants expressing pathogen-specific single-chain variable fragment (scFv) antibodies fused to antifungal peptides (AFPs), conferring resistance against fungal pathogens. We describe the selection from a phage display library of avian scFv antibodies that recognize cell surface proteins on fungi from the genus Fusarium, and the construction of scFv–AFP fusion protein constructs followed by their transient expression in tobacco (Nicotiana spp.) plants and stable expression in Arabidopsis thaliana plants. Using these techniques, the antibody fusion with the most promising in vitro activity can be used to generate transgenic plants that are resistant to pathogens such as Fusarium oxysporum f. sp. matthiolae.
