摘要： The present invention relates to methods for producing plants with increased fungal resistance, preferably seedling resistance against Northern Corn Leaf Blight. Further provided are methods for introducing, modifying, or modulating at least one wall-associated kinase (WAK) in(to) a plant cell, tissue, organ, or whole plant and thereby causing a reduced synthesis of benzoxazinoid and in turn increased fungal resistance. There are further provided methods to identify and/or modify downstream effector molecules in a WAK signalling cascade. Finally, plant cells, tissues, organs or whole plants having increased fungal resistance and methods using substances to activate signalling pathways in a targeted way are provided. The present invention thus relates to WAKs as master regulators and crucial signaling mediators in plant defense against fungal disease and the regulation and cross-talk mechanisms in the WAK signaling cascade and further gives examples for establishing novel anti-fungal strategies relevant for a series of crop plants.

摘要： The present invention relates to a nucleic acid molecule encoding a polypeptide conferring resistance to a plant against a fungal pathogen, such as Helminthosporium turcicum. The present invention further relates to a plant (or part thereof) comprising the nucleic acid molecule, and methods involving the nucleic acid molecule.

摘要： The present invention provides an improved Helminthosporium turcicum-resistant plant, in particular a maize plant which comprises a polynucleotide with one or more resistance-conferring genes, for example on a truncated chromosome fragment from the accession Pepitilla, as well as a cell, a tissue, a part, grain and seeds thereof, an isolated polynucleotide which comprises one or more resistance-conferring genes against Helminthosporium turcicum, a vector, a transgenic plant cell and a transgenic plant containing this polynucleotide. Furthermore, the invention encompasses suitable markers and their use in introducing resistance or the transgene into a plant, as well as the identification of improved maize plants which comprise a truncated chromosome fragment.
