    摘要： The present invention relates to a vector for introducing a desired gene into a plant, wherein a selectable marker gene introduced into a plant cell along with a desired gene is optionally removable from the DNA such as chromosome or the like where it exists and functions, then disappeared the function thereof after its expression, and the expression of the selectable marker gene and the disappearance of the function thereof are detectable by morphological change of the tissue derived from the plant cell into which the selectable marker gene is introduced. Also, the present invention constitutes a vector using a morphological abnormality induction gene as a selectable marker gene, while putting a removable DNA element under control of an inducible promoter, wherein the morphological abnormality induction gene is positioned such that it behaves integrally with the removable DNA element, and wherein a desired gene is positioned such that it does not behave integrally with the removable DNA element.

    摘要： The present invention is to provide a plant and a plant storage organ thereof in which GLP-1 derivatives are accumulated, and a method of producing them in order to develop a method for ingesting orally GLP-1 derivatives at a low cost and to make use of it in diabetic treatment. A transgenic plant or a plant storage organ thereof in which GLP-1 derivatives are accumulated cleavable with a digestive enzyme is produced by a method comprising: integrating into a vector a linked GLP-1s-DNA which comprises tandem repeated “n” DNAs (“n” being an integer of 3 or more) encoding a GLP-1 derivative consisting of GLP-1 (7-36) or of an amino acid sequence of GLP-1 (7-36) in which one or a few amino acids are deleted, substituted and/or added, and C-terminal consists of Arg or Lys, and having GLP-1 activity; introducing the vector into a plant cell; and redifferentiating the obtained transformant. The transgenic plant and the plant storage organ are useful as a pharmaceutical composition or a food or drink for treating or preventing diabetes.

    摘要： The present invention provides a method for highly producing a recombinant protein in a plant storage organ and a GLP-1 derivative. The plant storage organ in which the recombinant protein is highly produced is obtained by transformation with the use of a vector which comprises a recombinant protein gene, a cytokinin-related gene, a drug-resistant gene and a removable DNA element, in which the cytokinin-related gene and the drug-resistant gene exist in the positions so that they can behave together with the DNA element, while the recombinant protein to be expressed in the plant storage organ exists in the position so that it would not behave together with the DNA element. The GLP-1 is produced by using the method, and a derivative having been stabilized against enzymatic digestion is further provided.
