Abstract
The present invention relates to a method of increasing plant resistance to plant pathogens, particularly Sudden Death Syndrome in soybean against Fusarium virguliforme, through the use of Fusarium resistance nucleic acid molecules isolated from Glycine max and Fusarium virguliforme. In these plants, at least one heterologous Fusarium resistance protein is introduced in comparison to the wild-type plants to confer resistance to plant pathogens. The invention relates to transgenic plants and/or plant cells having increased resistance to plant pathogens, to expression vectors, transformed plants and plant cells as well as the use of such plants in a plant breeding program.
