A method for increasing the fungus resistance in transgenic plants by means of a host induced suppression of the gene expression in pathogenic fungus.

摘要

The present invention relates to a method for increasing the fungus resistance in transgenic plants, that is characterized in that a recombinant nucleic acid molecule, comprising a nucleic acid sequence homologous to a nucleic acid sequence of a fungus and / or is complementary and which, in the plant is transcribed, so that in the case of infection of the plant with this fungus the nucleic acid sequence transcribed in the plant with the homologous and / or complementary nucleic acid sequence of the fungus or parts thereof, interacts in such a way that the expression of the nucleic acid sequence of the fungus is substantially prevented, is introduced into the plant.The present invention also relates to a method for identification of fungus genes, in which the inhibition of their expression of fungus mediated resistance as well as the use of nucleic acid sequences, which leads to a nucleic acid sequence of one or more fungi and / or are complementary, for the production of transgenic plants with increased fungus resistance.
