発明の名称 (英語) USE OF GENE INVOLVED IN ACCUMULATION OF CADMIUM IN PLANTS コモンズ
発明の概要(英語) The purposes of the present invention are to identify a gene involved in accumulation of cadmium in plants and to provide a method for using the gene. Specifically, a polynucleotide encoding a polypeptide which comprises the amino acid sequence represented by SEQ ID NO: 1, a polynucleotide encoding a polypeptide which comprises an amino acid sequence produced by substituting, deleting and/or adding one or several amino acids in the amino acid sequence represented by SEQ ID NO: 1 and has an activity of changing the localization of the accumulation of cadmium, a polynucleotide encoding a polypeptide which comprises the amino acid sequence represented by SEQ ID NO: 2, or a polynucleotide encoding a polypeptide which comprises an amino acid sequence produced by substituting, deleting and/or adding one or several amino acids in the amino acid sequence represented by SEQ ID NO: 2 and has an activity of changing the localization of the accumulation of cadmium is introduced into a plant such that the polynucleotide is able to be expressed.
従来技術、競合技術の概要(英語) BACKGROUND ART
The causative agent of cadmium is known as itai-itai disease, toxic heavy metals. Cadmium is, during the mineral naturally present in the soil or heavy metals, silver, copper, the presence of the same with metals such as zinc, mining of these metals, and refining the discharged into the environment as a byproduct when accumulated in the soil.
Cadmium contaminated soil cultivated vegetables, cereal crops via various cadmium is taken into the human body, our with damaging consequences to health. For this reason, in Japan is to limit the amount of intake of cadmium from agricultural crops, by with a method, the reference value of the crop is included in the cadmium concentration determined. For example, 0.4 ppm or more the concentration of cadmium in the brown rice of less than 1.0 ppm of an edible rice marketed inhibited, the concentration of 1 ppm or more of the rice is cadmium, or the like of a sales processing, incineration being disposed as an entity.
Included in the rice crop such as cadmium concentration equal to or less than the reference value, in order to ensure the safety of the diet, conventional, soil washing, landfill, soil dressing by a method such as cadmium contaminated soil purification attempt has been made (for example, Patent Document 1 and see non-patent document 1).
