Patent number: 11932866Abstract: 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.Type: GrantFiled: March 1, 2020Date of Patent: March 19, 2024Assignee: KWS SAAT SE & Co.

Publication number: 20230313220Abstract: 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.Type: ApplicationFiled: January 13, 2023Publication date: October 5, 2023Applicant: KWS SAAT SE & Co. KGaAInventors: Aurelie BAK, Dietmar STAHL, Daniel STIRNWEIS, Daniela SCHEUERMANN, Bettina KESSEL

Patent number: 6386105Abstract: 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.Type: GrantFiled: March 27, 2000Date of Patent: May 14, 2002Assignee: MAN Roland Druckmaschinen AGInventor: Dietmar Stahl

Patent number: 6311619Abstract: 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.Type: GrantFiled: September 28, 2000Date of Patent: November 6, 2001Assignee: MAN Roland Druckmaschinen AGInventors: Rainer Stamme, Ulrich Jung, Franz-Peter Richter, Dietmar Stahl
