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.

Lox3 gene modulation and armyworm tolerance

The present invention provides an improved-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, 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.

Plant resistant to

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.
