  • Patent number: 11000035
    Abstract: Disclosed herein is a soil-borne disease control method capable of simply suppressing a soil-borne pathogen. The method for controlling a soil-borne disease includes applying at least one polyhydroxyalkanoic acid having a structure represented by the following formula (1) to soil: [—CHR—CH2—CO—O—]??(1) (wherein R is an alkyl group represented by CnH2n+1 and n is an integer of 1 or more but 15 or less).

  • Patent number: 10323251
    Abstract: A method for producing a plant cell comprising a mutation introduced in a target DNA comprises: a step of introducing into plant cells a DNA construct comprising a DNA homologous to a target DNA, wherein a desired mutation is introduced and a piggyBac transposon containing a marker gene is inserted in the homologous DNA; a step of selecting a plant cell, in which the mutation and the piggyBac transposon are introduced in the target DNA via homologous recombination, based on an expression of the marker gene; and a step of removing the piggyBac transposon from the target DNA by constitutively expressing a piggyBac transposase in the cell selected in the above step.

  • Patent number: 10301636
    Abstract: It has been found that a marker gene, which is inserted in the genomic DNA via homologous recombination, and to both ends of which nuclease recognition sites are added, can be removed from a plant cell by using a corresponding nuclease, and further that the nuclease recognition sites can also be removed without leaving any trace by matching sequences of at least 30 nucleotides adjacent to the recognition sites. Moreover, in a method for introducing a mutation into a target DNA on the genome of a plant cell via homologous recombination, it is made possible to: stably select a plant cell, in which the mutation is introduced, based on an expression of a marker gene; further, to remove an unnecessary sequence such as the marker gene from the selected cell; and to introduce only a required mutation into the target DNA.

  • Publication number: 20160288110
    Abstract: A photocatalyst including, as an active component, a reaction product obtained by mixing a reducing organic substance having iron-reducing ability or a feedstock for supplying the reducing organic substance with an iron-supplying source in the presence of water, in which the reaction product exhibits a photocatalytic activity when irradiated with light having a wavelength of ultraviolet light, visible light, or infrared light. An organic substance degradation method or a sterilization method including bringing the photocatalyst into contact with an object to be degraded or an object to be sterilized and irradiating the photocatalyst with light having a wavelength of ultraviolet light, visible light, or infrared light.

  • Patent number: 9372179
    Abstract: This invention provides a means for measuring a cholesterol content of a chicken egg by a non-destructive means. This invention relates to a method for measuring a cholesterol content of a chicken egg comprising: a step of light irradiation of irradiating the chicken egg with light in the visible to near-infrared wavelength range; a step of light detection of detecting light radiated from the chicken egg caused by that the light irradiated in the step of light irradiation is transmitted through the chicken egg or reflected inside the chicken egg; a step of spectrum acquisition of acquiring a near-infrared spectrum of the light detected in the step of light detection; and a step of cholesterol content determination of determining a cholesterol content of the chicken egg on the basis of the near-infrared spectrum acquired in the step of spectrum acquisition.
