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 disclosure is in the field of plant breeding and disease resistance. A method for the development of a corn plant enhanced for resistance to Colletotrichum graminicola and secondarily to Fusarium spp., both of which incite stalk rot disease, is provided. Also provided is a method to identify corn plants with polynucleotide sequences identified to serve as diagnostic markers for resistance to these pathogens. Further described is the introgression of desired genetic material from one or more parent plants into progeny with precision and accuracy to increase their resistance to these diseases with minimal linkage drag from the donor genome.

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.

摘要： The present application provides a new technology to confer or enhance insect resistance and, optionally also resistance to fungal pathogens in plants. In particular, the present invention provides a method for conferring or increasing resistance or tolerance to insect and optionally also to fungal pathogens in maize and oil seed rape (OSR) by targeting the endogenous Lox3 gene. By introducing either a gene silencing construct, a genome editing system or a genome modification, which leads to a targeted knock-down or knock-out of the Lox3 gene endogenous to the plant, a new or increased resistance to insect and, optionally fungal pathogens can be created.

摘要： The present invention relates to the identification and molecular characterization as well as to the use of genes and markers from a chromosomal interval which has a locus for cold tolerance in maize. The invention further relates to the development of molecular markers for assisting in growth, in particular for preventing a fixing of a “selective sweep” in a region with a low recombination rate, and to the provision of transgenic and non-transgenic plants, in particular maize plants, which show a newly mediated or increased cold tolerance.
