Abstract: There is provided an information input system enabling the realization of an input method easily understandable and operable by intuition. This information input system is provided with a camera 11 for picking up an image of a specified area including a fingertip OF of an operator and an input surface 17 as a photographed image, a contact discriminator 154 for discriminating whether or not the fingertip OF and the input surface 17 are in contact with each other by specifying the fingertip OF and the input surface 17 included in the photographed image, and a fingertip position detector 152 for detecting a relative position of the fingertip OF with respect to the input surface 17 when the contact discriminator 154 judges that the fingertip OF and the input surface 17 are in contact with each other.

Abstract: A mercapto-substituted imidazolylporphyrin metal complex monomer represented by a general formula (1): wherein R1 represents a group selected from the group consisting of an alkyl group, unsubstituted aryl group, alkyl-substituted aryl group and alkyloxy-substituted aryl group, M represents a metal ion selected from the group consisting of Zn(II), Ga(III), Fe(II), Co(II), and Ru(II), X represents a divalent linking group containing at least one group selected from the group consisting of an arylene group and an alkylene group, R2 represents a hydrogen atom or an acetyl group, and Im represents Im1 or Im2 set forth below: wherein R3 represents a hydrogen atom or an alkyl group.

Abstract: A method useful for stable expression of an exogenous gene, introduced into a plant, is provided. By introducing an exogenous gene and 5′ upstream sequence of tobacco dehydogenase concurrently, stable expression of the exogenous gene introduced into a plant can be achieved.

Abstract: The present invention relates to a method to improve the primary metabolism of a higher plant having chloroplasts by expressing fructose-1,6-bisphosphatase/sedoheptulose-1,7-bisphosphatase derived from Cyanobacterium synechococcus in the chloroplasts. The invention further relates to transgenic plants comprising DNA encoding fructose-1,6-bisphosphatase/sedoheptulose-1,7-bisphosphatase derived from Cyanobacterium synechococcus.

Abstract: A concise method to promote growth of a plant useful for increase of food production. This invention provides a method to promote growth of a plant by administration of formic acid, an organic acid with a low molecular weight through avoidance of photo-oxidation damage. This invention also provides amino acid sequence of formate dehydrogenase and base sequence encoding the enzyme. The expression of the enzyme is induced by administration of formic acid and the enzyme is involved in metabolism of formic acid and its salts. Furthermore, this invention provides a method to promote growth of a plant by administration of methanol through avoidance of photo-oxidation damage.

Abstract: A poly(porphyrin) represented by a general formula (I) below, which is useful as a molecular wire conducting photonic and electronic energy: where M is a metal ion selected from the group consisting of Zn, Ga, Ru, Fe and Co, R1 is a group selected from the group consisting of alkyl group, unsubstituted aryl group, alkyl-substituted aryl group, and alkyloxy-substituted aryl group, Im is represented by the following formula: where R2 denotes a hydrogen atom or a methyl group, and n is an integer of 1 or more, provided that the central metal ion represented by M may be coordinated or not coordinated to at least one of the porphyrin rings positioned at both ends of the general formula (I).

Abstract: A method of genetic improvement of coffee plants, using technique of molecular bleeding, is disclosed. The method provides a transformant of coffee plants produced from embryogenic calli, using Agrobacterium method.

Abstract: A method for the stable expression of an introduced exogenous gene in a plant or plant cell is provided. Stable expression of an exogenous gene that was introduced was achieved by operably linking an upstream sequence of sea urchin arylsulfatase gene as an insulator.
