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.

A waste incinerator is provided which can completely prevent environmental pollution by dioxins. Exhaust gas from an incinerator is guided into a glass melting furnace by a duct, and blown into molten glass through a bubbling pipe to decompose dioxins in the exhaust gas. High-temperature gas produced in the glass melting furnace is supplied into the incinerator by a pipe so as to burn wastes without using auxiliary fuel. Further, exhaust gas is pressurized by pressure pumps in a pipe branching from the duct, while fuel tablets to including ashes are introduced through a fuel inlet and fed into the molten glass under the pressure of exhaust gas to decompose dioxins in the ashes.
