  • Patent number: 11932866
    Abstract: The present invention relates to the field of plant biotechnology. Specifically, there are provided methods and nucleic acid sequences for obtaining pathogen resistance in plants and for generating resistant plants. In particular, the role of a central molecule in plant immunity is studied. Based on the mechanisms elucidated, the present invention provides strategies to specifically modulate said phosphatase-like protein family member molecule by different transient and/or stable techniques, alone or in combination, to achieve a robust increased of pathogen resistance in different target plants to obtain inherently pathogen resistant plants and plant materials to avoid severe harvest losses as caused by major plant pathogens by biological means instead of herbicide or pesticide treatment.

  • Publication number: 20230313220
    Abstract: 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.

  • Publication number: 20210246463
    Abstract: The invention is related to nucleic acids encoding resistance proteins, avirulence proteins, or both, wherein at least one of the proteins include at least one amino acid substitution in comparison to the wild type amino acid sequence of the resistance and/or avirulence protein, said substitution leading to a decrease of cell death during a hypersensitive reaction. Furthermore, the invention does also encompass an expression cassette, a vector, a cell, a plant, plant tissue or plant seed comprising on of the nucleic acids or one of the proteins. Finally, the invention provides a method for increasing a plant's resistance towards at least one plant pathogen.

  • Publication number: 20150159170
    Abstract: The present invention provides pathogen-resistant transgenic plants which exhibit a resistance protein-mediated pathogen defence reaction in a cell of the plant under stringent control owing to a pathogen infection. In this case, as inducer of the pathogen defence, parts of avirulence proteins are used, the stable integration of which is possible by means of usual transformation methods. In addition, the invention relates to a composition of nucleic acids which, after integration into the genome of a plant, mediates the pathogen resistance therein, to a method for producing a pathogen-resistant plant, and to plants for producing a pathogen-resistant plant.

  • Patent number: 6386105
    Abstract: An apparatus and method for removing and cleaning ink from an ink fountain in a rotary printing press. The ink fountain includes an ink fountain container having a fountain roll disposed adjacent an open side thereof. The apparatus includes a scraping device for forcing ink from the container in the direction of the inking roll, and a metering device disposed between the container and fountain roll which is movable to an open position to form a gap between the fountain roll and container through which ink forced by the scraping device is directed into an underlying catching trough. The container further includes a doctor blade positionable into adjacent relation to the fountain roll for removing ink from the fountain roll during a cleaning operation and directing the removed ink into the catching trough so as to preclude contamination of the downstream roll train of the inking unit.

  • Patent number: 6311619
    Abstract: The invention relates to a sheet-fed rotary printing machine with printing units for multi-color printing and with at least one coating unit. The object of the invention is, inter alia, to provide a sheet-fed rotary printing machine of the type described in the introduction, in which at least one coating unit can be used more universally and set-up times are reduced. This is achieved in that the coating unit 2, 3 is formed from an impression cylinder 10, a form cylinder 12 and a metering system 14 with a screened applicator roller 13. The applicator roller 13 has a circular segment congruent to the cylinder pit of the form cylinder 12, is at least the same size as the form cylinder 12 and can be imaged as a rough intaglio printing form.
