PROBLEM TO BE SOLVED: To provide compositions and methods for targeted introduction of exogenous sequences into a genome of a plant cell.SOLUTION: A method for introduction of exogenous sequences into a genome of a plant cell comprises (a) a step of contacting the plant cell with a donor DNA vector comprising first and second and fifth DNA sequences in which the fifth sequence comprises the DNA vector to be introduced, and is inserted between the first and second sequences of the donor DNA vector, wherein third and fourth sequences in the genome of the plant cell can be chromosomal DNA sequences, (b) causing each fusion protein of a pair of fusion protein to expresses a nuclease which is a fusions between a cleavage domain of a Fok I restriction endonuclease and an engineered zinc finger binding domain in the cell to cleave a chromosomal DNA at one or more corresponding target site between the third and fourth sequences.

PROBLEM TO BE SOLVED: To provide composite materials that are palatable to a wood-destroying pest species and also pesticidal to the pest species can be used in pest control devices and can be used as wood substitutes for structural components, which are resistant to destruction by wood-destroying pests.SOLUTION: Composite materials include a thermoplastic polymer, a food material for the pest and a pesticide. The composite material is formed by mixing a thermoplastic polymer, wood fragments or other cellulosic materials and a quantity of pesticide, and thereafter creating a molten material within a mixer, compounder, extruder or the like. The molten material is extruded or molded to form the desired shape.

PROBLEM TO BE SOLVED: To provide a versatile method for preparing a substituted pyridine having an electron-attractive substituent at the 4-position.SOLUTION: The substituted pyridine derivative is prepared by reacting an α,β-unsaturated carbonyl compound expressed by formula: R-C(O)-C(R)=C(R)-G, where in formula, Rand Rare each independently represents H, a 1-20C alkyl group or the like; Rrepresents CN, NO, a 1-20C alkyl group or the like; and G represents an amino group or a leaving group, with a Wittig reagent or Horner-Wadsworth-Emmons reagent in the presence of a base, and by optionally conducting subsequent cyclization.

PROBLEM TO BE SOLVED: To provide a composition reduced in crystallization velocity of a pesticide active ingredient; and to provide a method for reducing the crystallization velocity using the composition.SOLUTION: The composition comprises (a) one or more species of pesticides and (b) one or more species of oil-soluble polymers having 6.9-9.0 solubility parameter and selected from (1) polymers having lipophilicity and (2) polymers having both lipophilicity and hydrophilicity. In the composition, each pesticide is soluble in at least one kind of the group consisting of (1) monomers for producing the polymers, (2) oligomers having almost the same ratio of a monomer unit composition as that of the polymers, (3) the polymers and (4) solutions of the polymers and organic solvents.
