摘要： The present invention relates to the transformation of C4 plants. It also relates to the high-level expression of foreign genes in C4 plants. More specifically, the present invention relates to the creation of C4 plants retaining an excellent photosynthetic capacity at low temperature by achieving high-level expression of an enzyme constituting the C4 photosynthetic pathway. In the present invention, C4 plants are transformed using an expression cassette that comprises a promoter, a C4 plant genomic gene, under control of said promoter, encoding an enzyme constituting a photosynthetic pathway, and a terminator. The C4 plant genomic gene encoding an enzyme constituting a photosynthetic pathway is preferably a C4 plant genome-derived PPDK gene or a modified form thereof. The present invention is particularly useful in improving the production of C4 plants having PPDK (especially, in improving the production of maize under low temperature conditions).

摘要： A method for expressing a foreign gene, by which the foreign genes can be expressed more strongly than by the conventional methods, as well as a recombinant vector therefor, is disclosed. In the method for expressing a foreign gene according to the present invention, the foreign gene is inserted into a site downstream of a promoter and the foreign gene is expressed in a cell, wherein a plurality of intron-originated DNA fragments which are the same or different and are capable of promoting expression of foreign genes are inserted into one or more sites upstream of the foreign gene, and said foreign gene is expressed.

摘要： The current invention relates to an anti-fouling system for substances in contact with seawater which is constituted of the first conductive membrane that is coated on the outer side of the electric insulator mounted at the surface of the substance such as ships, marine structures in contact with seawater and is composed of thin sheets of metals having low specific resistance or metal oxide, spray-coated membrane, evaporated membrane or fused membrane, and the second conductive anti-fouling membrane having higher electric resistance than the first conductive membrane which is coated on the outer side of the above first conductive membrane and which is composed of the oxidation-resistant insoluble substance and the organic binder, and the power supply equipment that supplies direct currents flowing from the first conductive membrane through the second conductive membrane toward the electric conductor made of iron, copper or carbon located in seawater and opposite the second conductive membrane, owing to the constitution of which the prevention of rise in resistance because of consumption of the conductive membrane, the uniforming of current distribution and a high anti-fouling performance by using the low-resistant conductive membrane are achieved.
