The invention provides transgenic plants with resistance to infection by a
root-infecting fungal plant pathogen such as Phymatotrichopsis omnivora.
Also provided are methods of making such plants. Further provided are
nucleic acid vectors for producing such a plant. Additionally, methods
are provided for growing a dicotyledonous plant that is resistant to root
rot disease in soil that comprises Phymatotrichopsis omnivora, or another
pathogen.
