Patent number: 9018444Abstract: The present invention is to provide a novel non-diffusing plant virus vector wherein virus vector infection and proliferation are possible only in a recombinant plant transformed with a gene necessary for viral proliferation, thereby enabling avoidance of unintended diffusion of a recombinant virus, a selective and specific expression system therefor, and a method of expression thereof which comprises combining a non-diffusing virus vector lacking a gene involved in intercellular movement of a cucumber mosaic virus (CMV) genome and a transgenic plant transformed with the lacked gene involved in intercellular movement for the non-diffusing virus vector to establish infection and proliferation selectively and specifically in the transgenic plant.Type: GrantFiled: August 7, 2009Date of Patent: April 28, 2015Assignees: National Institute of Advanced Industrial Science and Technology, The Hokuren Federation of Agricultural Cooperatives, National University Corporation Hokkaido UniversityInventors: Noriho Fukuzawa, Takeshi Matsumura, Noriko Itchoda, Takeaki Ishihara, Chikara Masuta

Patent number: 7632676Abstract: A novel plant virus vector and a method of gene expression into plants are provided, and the present invention relates to a plant virus vector characterized in that a part of the sequence of the 2b region of the RNA2 molecule of the Cucumber mosaic virus (CMV) is deleted; the aforementioned plant virus vector characterized in that the region from the StuI site to the stop codon of the 2b ORF of pCY2, which is an infectious clone of CMV-Y RNA2, is deleted; and a method of gene expression in plants characterized in that a foreign gene is introduced so as to be stably expressed in a plant using the genetic recombinant. This vector is useful as a plant RNA vector for causing stable expression of foreign genes.Type: GrantFiled: June 25, 2004Date of Patent: December 15, 2009Assignees: National Institute of Advanced Industrial Science and Technology, Hokuren Federation of Agricultural Cooperatives, National University Corporation Hokkaido UniversityInventors: Chikara Masuta, Takeshi Matsumura, Noriko Itchoda

Patent number: 5840705Abstract: This invention relates an .alpha.-glucosidase inhibitor mildly inhibiting .alpha.-glucosidase locally present in the micro-villus of small intestine, a composition principally comprising sugar and containing the inhibitor, a food, a sweetener and a feed. The inhibitor delays the digestion of starch, starch-derived oligosaccharides and sucrose, so that the inhibitor has an action of suppressing rapid increase in blood glucose level and an action of suppressing insulin secretion at a lower level. Thus, the inhibitor is useful for the prophylaxis of obesity and diabetes mellitus. The .alpha.-glucosidase inhibitor of the present invention is composed of nucleotide, nucleoside, or base as the structural component of nucleic acid and one or two or more digestible sugars selected from sucrose, starch and starch-derived oligosaccharide. The .alpha.-glucosidase inhibitor mildly inhibits the action of .alpha.Type: GrantFiled: February 21, 1996Date of Patent: November 24, 1998Assignee: The Hokuren Federation of Agricultural CooperativesInventors: Masayuki Tsukada, Hiroyuki Takeda, Norio Maeda, Yasunori Fukumori, Norio Shiomi, Shuichi Onodera, Takuji Fujisawa

Patent number: 5463038Abstract: The present invention relates to crystals of 1-kestose which is a fructooligosaccharide, and it is an object of the present invention to provide high-purity 1-kestose crystals having no hygroscopicity and a method of producing the crystals. Methanol is added to an aqueous solution containing as a main ingredient 1-kestose with a purity of 80% or more, and the mixture is then dried. Methanol is further added to the mixture to obtain 1-kestose crystals with a purity of 90% or more. An aqueous solution with a purity of 70% or more is concentrated, and 1-kestose microcrystals are added to the concentrate obtained to separate 1-kestose crystals with a purity of 94 to 99.9%.Type: GrantFiled: September 4, 1992Date of Patent: October 31, 1995Assignee: The Hokuren Federation of Agricultural CooperativesInventors: Tetsuhiro Hidano, Hiroyuki Takeda, Masayuki Tsukada, Kazuo Yamamoto, Atsushi Inoue

Patent number: 4183807Abstract: Newly isolated polysaccharide assimilating yeasts are added to a waste water rich in nutrients thereby making such yeasts assimilate nutrients, so that B.O.D. of the waste water is efficiently decreased. Among the polysaccharide assimilating yeasts, ellipsoideus YS-1, FERM-P No. 4498, in particular, can decompose and assimilate sulfurous acid, starch and protein at once, and therefore the B.O.D. of the waste water from starch production plants can be considerably decreased.Type: GrantFiled: September 11, 1978Date of Patent: January 15, 1980Assignees: National Tax Administration Agency, Toho Zinc Co.
