Abstract: The invention relates to a method for production of transgenic plants and/or plant cells with increased pathogenic resistance, whereby the transgenic plants or plant cells have an altered content or an altered activity of at least one actin-depolymerising factor (ADF) with relation to the wild type. The invention also relates to the use of nucleic acids, coding for at least one ADF, for the production of transgenic plants or plant cells with increased pathogenic resistance and, furthermore, nucleic acid sequences coding for an ADF.

Abstract: The invention relates to methods of producing transgenic plants including pathogen resistant plants with recombinant nucleic acid molecules comprising promoter regions which provides expression of a desired transgene in epidermis-specific manner, and transgenic plants produced by said methods.

Abstract: The present invention is directed to pesticidal compositions comprising indole derivatives. These indole derivatives are especially active against phytopathogenic fungi. Furthermore, the invention relates to the use of indole derivatives for the production of pesticides and the use of the compositions according to the invention as pesticides. The present invention is also directed to a process for producing a pesticidal composition and to pesticidal compositions prepared by this process. In addition, the invention relates to a process for preventing or combating pests and to a process for protecting plants against pests, especially against phytopathogenic fungi. Further, the invention is directed to plants or seeds as well as objects or materials which have been protected against pests by treatment with a composition according to the invention. Further, the invention is directed to a method for identifying a substance having pesticidal activity.

Abstract: Disclosed are polynucleotides that encode a beta-glucosidase belonging to the plant protein class of family 1 glycoside hydrolases. Furthermore described are recombinant nucleic molecules and vectors containing these polynucleotides and host cells, preferably plant cells that are genetically engineered with these polynucleotides. In addition, transgenic plants are disclosed which show an increased activity of the beta-glucosidase described, preferably leading to an improved resistance against plant pathogens. In another aspect, the present application discloses screening methods for identifying a substrate for said betaglucosidase and methods for the production of plant protection compositions from such substrates or hydrolysis products thereof. Furthermore, methods and uses are disclosed which apply the polynucleotides encoding the beta-glucosidase described in order to improve resistance in plants against plant pathogens.
