Abstract: The disclosure provides novel corn, tomato, and soybean U6, U3, U2, U5, and 7SL snRNA promoters which are useful for CRISPR/Cas-mediated targeted gene modifications in plants. The disclosure also provides methods for use for U6, U3, U2, U5, and 7SL promoters in driving expression of sgRNA polynucleotides which function in a CRISPR/Cas system of targeted gene modification in plants. The disclosure also provides methods of genome modification by insertion of blunt-end DNA fragments at a site of genomic cleavage.

Abstract: A light fixture for illuminating a specific target area is disclosed. The light fixture includes an extended light source that emits light from a surface. The light source emits light from the surface in directions towards the target area and away from the target area. The light fixture also includes a reflector arrangement configured to redirect the light that would otherwise be emitted from the surface of the light source in directions away from the target area to directions towards the target area such that substantially all the light emitted from the light source is made incident in or directed into the target area.

Abstract: A toilet system providing improved convenience, efficiency and sanitation with automatic operation. Basically, the toilet includes a bowl, a seat partially covering the bowl opening and a lid movable between a raised position exposing the seat and a lower position covering the seat and sealing the bowl. When the lid is raised, an air extraction system removes air and odors from the bowl. After use, the lid is either manually or automatically closed, initiating a high or low flush. When left to close automatically a low flush only is initiated. In a low flush, water is directed under pressure through two rotating spray jets against the bowl interior, then is removed along with any toilet contents by the rotating jets action and the macerator which reduces solids to small particles. Heated air is then directed into the bowl to dry the bowl. In a high flush, an additional spray jet cleans the seat and a larger quantity (typically 1/3 additional) of water is used.
