  • Publication number: 20060168675
    Abstract: The invention relates to a novel polypeptide participating in biotin biosynthesis of plant, a polynucleotide encoding the said polypeptide, a method for inducing plant growth inhibition by suppressing the expression or function of the said polypeptide, resulting in inhibition of biotin biosynthesis, and a method for identifying herbicidal compounds that inhibit the expression or function of the said polypeptide. Biotin biosynthesis is an essential process for the growth of plants, however, the process is not present in both human and animals. Therefore, the compounds suppressing the expression or function of the novel polypeptide that relates to biotin biosynthesis can be effectively used as a new herbicide doing human and animals no harm.

  • Patent number: 6583831
    Abstract: Disclosed is a liquid crystal display device capable of preventing a grounding clip, which is combined to an end of a mold frame to ground a printed circuit board to a top chassis, from making electrical contact with a display unit. A guide projection is formed at the end of the mold frame so as to be placed adjacent to the grounding clip. A gap between the guide projection and the liquid crystal display panel is narrower than a gap between the liquid crystal display panel and the grounding clip. Accordingly, even though the mold frame is bent by means of an outerforce applied to both ends of the mold frame, it is possible to prevent the grounding clip from deforming and making electrical contact with the liquid crystal display panel.
