  • Patent number: 8735654
    Abstract: The invention relates to a method of generating or increasing a pathogen resistance in plants by reducing the expression of at least one Armadillo repeat polypeptide or a functional equivalent thereof. The invention relates to novel nucleic acid sequences coding for a Hordeum vulgare Armadillo repeat (HvARM) polynucleotide and describes homologous sequences (ARM1) thereof, and to their use in methods for obtaining a pathogen resistance in plants e, and to nucleic acid constructs, expression cassettes and vectors which comprise these sequences and which are suitable for mediating a fungal resistance in plants. The invention furthermore relates to transgenic organisms, in particular plants, which are transformed with these expression cassettes or vectors, and to cultures, parts or transgenic propagation material derived therefrom.
    Type: Grant

  • Patent number: 8329988
    Abstract: The invention relates to a method of increasing the resistance to one or more penetrating pathogen(s) in a monocotyledonous or dicotyledonous plant or a part of a plant, for example in an organ, tissue, a cell or a part of a plant cell, for example in an organell, wherein a DNA sequence which codes for an armadillo repeat ARM1 protein and which mediates an increased pathogen resistance, preferably an increased resistance to fungal pathogens, is increased into, and expressed in, the plant or plant cell; or wherein an endogenous DNA sequence which codes for an armadillo repeat ARM1 protein and which mediates an increased pathogen resistance, preferably an increased resistance to fungal pathogens, is increased in the plant or plant cell in comparison with the original, or wild-type, plant, or wherein the endogenous gene sequence or preferably the 5?-untranslated region (5?UTR) is modified in comparison with the original sequence.

  • Patent number: 8222486
    Abstract: The present invention relates to a method of increasing the pathogen resistance in transgenic plants and/or plant cells, where a DNA sequence which codes for a protein with a leucine-rich-repeat (LRR) domain and/or a kinase activity is introduced into the plant or plant cell and expressed therein. The present invention also relates to the use of nucleic acids which code for such a protein, for the generation of transgenic plants or plant cells with an increased pathogen resistance. The present invention furthermore relates to nucleic acid sequences which code for a protein which confers an increased pathogen resistance in plants.
