  • Patent number: 9145563
    Abstract: An object of the present invention is to provide a transgenic plant on which a useful phenotype is conferred by regulating expression of pseudo-response regulator (PRR) genes with an approach that is different from deletion of PRR genes. According to the present invention, there is provided a transgenic plant into which a polynucleotide encoding a protein comprising a CCT motif and a pseudo-receiver domain which is a common motif of plant pseudo-response regulator genes, a fusion polynucleotide of said polynucleotide and a polynucleotide encoding at least one transcription activation domain of a transcription factor, or a recombinant vector comprising said polynucleotide or fusion polynucleotide has been introduced.

  • Patent number: 8962920
    Abstract: Cytokinin is a plant hormone that regulates various physiological activities including cell division, cell cycle, cellular senescence, and axillary buds outgrowth. The present invention provides a method for producing a transformed plant by introducing an isolated nucleic acid or recombinant vector containing the isolated nucleic acid into a plant cell such that the amount of active cytokinin synthesized from nucleotide cytokinin is increased in the plant cell and by regenerating a plant body from the plant cell.

  • Patent number: 7946624
    Abstract: The present invention includes a mounting structure having a flange and a plurality of hook portions formed integrally with a piping member. The flange can contact a first surface of an element having a through-hole formed therein. The hook portions extend from the flange for inserting into the through-hole and can resiliently deform in a radial direction with respect to the axis of the flange. Each hook portion has a hooking end that can engage a second surface of the element opposite to the first surface.
