The present invention relates to a method for increasing the vigor and/or crop yield of agricultural plants under essentially non-existent pathogen pressure, wherein the plants, the plant propagules, the seed of the plants and/or a locus where the plants are growing or are intended to grow are treated with an effective amount of a composition comprising astrain with NRRL Accession No. B-21661, a mutant of the strain having all the identifying characteristics of the strain, or a cell-free extract thereof; and a compound selected from the group consisting of fosetyl, fosetyl-aluminum, propamocarb, and propamocarb hydrochloride; wherein the vigor and/or crop yield of agricultural plants under essentially non-existent pathogen pressure is increased.

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 asubtilisin (HvRNR9) andsubtilisin (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.

Use of subtilisin-like RNR9 polynucleotide for achieving pathogen resistance in plants

The present invention relates to methods of generating or increasing resistance to at least one biotrophic pathogen in a plant or a part of a plant by increasing the protein quantity or function of at least one Bax Inhibitor-1 (BI-1) protein in at least one part of the plant. Moreover, the invention relates to polypeptide sequences and nucleic acid sequences which code for a BI-1 protein, and to expression cassettes, vectors and organisms which comprise such sequences or such a protein.

Methods for increasing the resistance in plants to biotropic fungi

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&#x2032;UTR) is modified in comparison with the original sequence. The invention also relates to plants, to parts of a plant, for example an organ, tissue, a cell or a part of a plant cell, for example an organelle, which are obtained by the above methods, and to corresponding propagation material.
