A solution containing a C 70 cyclodextrin complex and a solution containing a lipid that is capable of forming a liposome are mixed together at a temperature in a range of 10 °C to 45 °C. This produces a C 70 -incorporated liposome which keeps a physical property that the C 70 fullerene originally has, and is stably solubilized in a polar solvent. Hence, the present invention provides a C 70 -incorporated liposome which keeps a physical property that the C 70 fullerene originally has, and which is stably solubilized in a polar solvent, a production method of the same, and a use of the same.

Four genes, A622, NBBl, PMT, and QPT, can be influenced for increasing nicotinic alkaloid levels in Nicotiana plants, as well as for synthesizing nicotinic alkaloids in non-nicotine producing plants and cells. In particular, overexpressing one or more of A622, NBBl, PMT, and QPT may be used to increase nicotine and nicotinic alkaloid levels in tobacco plants. Non-nicotine producing cells can be engineered to produce nicotine and related compounds by overexpressing A622 and NBBl.

A spherical aberration correction decelerating lens corrects a spherical aberration occurring in an electron beam or an ion beam (hereinafter, referred to as "beam") emitted from a predetermined object plane position with a certain divergence angle, and said spherical aberration correction decelerating lens comprises at least two electrodes, each of which is constituted of a surface of a solid of revolution whose central axis coincides with an optical axis and each of which receives an intentionally set voltage applied by an external power supply, wherein at least one of the electrodes includes one or more meshes (M) which has a concaved shape opposite to an object plane (P0) and which is constituted of a surface of a solid of revolution so that a central axis of the concaved shape coincides with the optical axis, and a voltage applied to each of the electrodes causes the beam to be decelerated and causes formation of a decelerating convergence field for correcting the spherical aberration occurring in the beam. This makes it possible to provide a spherical aberration correction decelerating lens which converges a beam, emitted from the sample and having high energy and a large divergence angle, onto an image plane.

According to a circular dichroism fluorescent microscope 100, it is possible to analyze, by using a small amount of a sample and directly in a living organism, a high-order structure of the sample such as a biomolecule, for example, protein and the like. The circular dichroism fluorescent microscope 100 includes a confocal section (115). In the circular dichroism fluorescent microscope 100, a circularly polarizing/modulating section (105) converts, into right and left circularly polarized lights, a light beam emitted from a light source (103). Thus obtained right and left circularly polarized light is focused on the sample so that the sample is irradiated with the right and left circularly polarized lights. Then, an optical lens (102) focuses fluorescence emitted from the sample. Further, a wavelength selecting section (107) transmits only fluorescence having a predetermined wavelength. Subsequently, the fluorescence having passed through the wavelength selecting section 107 is detected. Based on fluorescent intensity signals of the fluorescence thus detected, a difference between (i) an intensity of the fluorescence emitted from the sample at the time of irradiation with the use of the right circularly polarized light and (ii) an intensity of the fluorescence emitted from the sample at the time of irradiation with the use of the left circularly polarized light is calculated.

Novel Bacillus subtilis mutant strains having good productivity of various enzymes are provided through extensive analysis of strains that are derived from Bacillus subtilis via gene disruption. The Bacillus subtilis mutant strains according to the present invention have genomic structures prepared by deletion of regions listed in the columns for deficient regions. Each of these Bacillus subtilis mutant strains exerts significantly improved secretory productivity of a protein when a gene encoding such a secretory target protein is introduced so that it can be expressed, compared with a case in which the same gene is introduced into a wild-type strain.

摘要:
According to the present invention, a novel method for promoting fatty acid content in a plant is provided. In this method, the promoter of accD gene of acetyl-CoA carboxylase was replaced with a promoter directing abundant expression in plastids and chloroplasts by using plastid transformation. This method increases the carboxyltransferase beta subunit protein encoded by the accD gene. Accompanied with it, the other subunits constituting the acetyl-CoA carboxylase apparently increases and this enzyme increases. Since the acetyl-CoA carboxylase is a key enzyme for rate-limiting step of fatty acid synthesis, synthesis of fatty acid can be promoted by the method of the present invention. The transformed plant produced according to the method of the present invention exhibits remarkable enhancement in the fatty acid content in leaves and seeds. Moreover, the leaf longevity extended and the number of the seeds per a plant body increased, thereby seed oil and productivity of the plant are improved.
