Patent number: 11845947Abstract: 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.Type: GrantFiled: December 16, 2020Date of Patent: December 19, 2023Assignees: KWS SAAT SE & CO. KGAA, UNIVERSITÄT ZÜRICHInventors: Milena Ouzunova, Daniela Scheuermann, Beat Keller, Simon Krattinger, Thomas Wicker, Gerhard Herren, Severine Hurni, Bettina Kessel, Thomas Presterl, Carsten Knaak

Publication number: 20230054527Abstract: The present invention relates to maize plants having increased pathogen resistance or tolerance, in particular increased resistance or tolerance to pathogens causing Northern Corn Leaf Blight, i.e. Exserohilum turcicum. Such maize plants can be characterized as having a particular QTL allele comprising one or more resistance gene, or particular molecular markers in chromosome 4 based on donor line H102. The invention further relates to methods for generating such maize plants, as well as methods for identifying such maize plants.Type: ApplicationFiled: December 18, 2020Publication date: February 23, 2023Applicant: KWS SAAT SE & Co. KGaAInventors: Daniela SCHEUERMANN, Thomas PRESTERL, Bettina KESSEL, Dietmar STAHL, Daniel Fabian STIRNWEIS

Publication number: 20220251592Abstract: 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.Type: ApplicationFiled: April 22, 2022Publication date: August 11, 2022Applicant: KWS SAAT SE & CO. KGAAInventors: Milena OUZUNOVA, Thomas PRESTERL, Carsten KNAAK, Daniela SCHEUERMANN, Claude URBANY, Peter WESTHOFF, Elena PESTSOVA, Karin ERNST

Publication number: 20220243287Abstract: The present invention relates to a QTL allele in maize associated with drought resistance and carbon isotope composition as well as specific marker alleles associated with the QTL allele. The present invention further relates methods for identifying maize plants based on screening for the presence of the QTL allele or marker alleles. The invention also relates to methods for modifying drought resistance and carbon isotope composition in maize plants.Type: ApplicationFiled: May 13, 2020Publication date: August 4, 2022Applicants: KWS SAAT SE & Co.
