Abstract: Disclosed herein are recombinant meganucleases engineered to bind and cleave a recognition sequence in the mitochondrial DNA (mtDNA) of a eukaryotic cell, such as a plant cell. The disclosure further relates to the use of such recombinant meganucleases in methods for producing genetically-modified eukaryotic cells, and to a population of genetically-modified eukaryotic cells wherein the mtDNA has been having modified or edited.

Abstract: A housing of a device comprises a screw boss that extends outwardly from a first base plate proximate to a corner of the housing. Additionally, the housing of the device includes a force dissipation member. The force dissipation member includes a central portion that is sized to detachably attach around the screw boss. The force dissipation member further includes at least two arms that extend outwardly from the central portion, wherein each arm of the at least two arms is attached to a different side of the two walls of the housing.

Abstract: An inflator probe for filling gas containers and the like comprising a one-piece body molded from suitable plastic material and providing a cylindrical externally threaded end piece for attachment to a pump followed by an enlarged-diameter shoulder with an elongated tapered nozzle extending therefrom insertable into the inflatable container, an internal center bore commencing at the threaded end reduced to form a circular ridge acting as a seat for a ball positioned in a chamber formed in the end piece, the ball sealing against back flow of gas between strokes of the pump, a non-circular restricted throat providing communication between the chamber and the bore for the flow of gas forced by the pump toward the nozzle outlet but restraining passage of the ball through the bore, the molding material being sufficient resilient to permit insertion and retention of the ball within the chamber after molding and including therein a lubricant for assisting easy entry of the nozzle into the inflatable container.
