Abstract: The present invention has for its object to provide a transgenic bird with a foreign gene containing a feline-derived protein-encoding sequence as transferred therein, and a method of producing the same. The present invention provides a method of producing a feline-derived protein by using a transgenic bird with a method which comprises infecting an avian embryo with a replication defective retrovirus vector containing a foreign gene by microinjection thereof into the early heart or blood vessel formed in the embryo and allowing the embryo to hatch.

Abstract: The present invention provides a G1 transgenic bird or an offspring thereof by: incubating a fertilized avian egg, microinjecting, into the early embryo thereof at a stage except for and after the blastodermic stage just after egg laying, a replication-deficient retroviral vector coding for a useful protein, allowing the egg to hatch out to thereby obtain a G0 transgenic chimeric bird, and mating the G0 transgenic chimeric bird with another G0 transgenic chimeric bird or an offspring thereof or with a wild-type bird.

Abstract: The object of the present invention is to provide a heat resistant thermally conductive material, to which fine powder such as dust, toner, and the like are hard to adhere, and which has good heat radiative properties. To attain this object, the present invention provides a heat resistant thermally conductive material, being made from an organic-inorganic hybrid material, which is prepared by heating a sol containing a metal or semimetal alkoxide, and an organo-silicon compound, plus a high thermally conductive filler, to gel said sol. Said organic-inorganic hybrid has excellent mold release characteristics, so that dust, toner, and the like don't easily adhere to the thermally conductive material, and if dust, toner and the like adhere to the thermally conductive material, they are easily removed therefrom. Further, said more highly thermally conductive filler imparts good heat radiative properties to said organic-inorganic hybrid.

Abstract: The present invention is to provide a method which comprises providing a plant with characters of a repressor and operator both constituting a gene expression inducing system with an actinomycete autogenous regulatory factor as an inducer by gene transfer and administering the actinomycete autogenous regulatory factor to the transformed plant to thereby induce the expression of a gene placed under the control of the operator at a site of administration of the actinomycete autogenous regulatory factor. This method makes it possible to cause expression of a desired gene at a desired time and site, thus enabling even the production, in a plant, of a metabolite otherwise disadvantageous to the growth of the plant. It is also useful in preventing transformant plants from spreading through the environment by controlling the fertility thereof.
