Estimating the term…
The invention relates to a method of generating or increasing a pathogen resistance in plants by reducing the expression of at least one subtilisin polypeptide or a functional equivalent thereof. The invention relates to novel nucleic acid sequences coding for a Hordeum vulgare subtilisin (HvRNR9) and Triticum aestivum subtilisin (TaRNR9) polynucleotide and describes homologous sequences (RNR9) thereof, and to their use in methods for obtaining a pathogen resistance in plants, 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.
A method of increasing the resistance to pathogens in a plant or in a part of a plant, comprising altering cell wall structure.
A method of increasing the resistance to pathogens in a plant or in a part of a plant, comprising reducing the activity of a subtilisin RNR9 polypeptide in a plant or in a part of the plant.
An isolated nucleic acid molecule coding for a subtilisin RNR9 protein, comprising at least one nucleic acid molecule selected from the group consisting of:
A nucleic acid construct comprising a nucleic acid molelcule comprising at least one fragment of a nucleic acid molecule which is antisense or sense relative to a nucleic acid molecule coding for subtilisin RNR9 polypeptide in operable linkage with a promoter selected from the group consisting of barley promoter, maize promoter, rice promoter, pathogen-inducible promoter, epidermis- and/or mesophyll-specific promoter and lemma-, palca- and/or glume (anther promodium)-specific promoter.
