Title NOVEL IRON-ZINC BINDING CONTROL FACTOR, AND TECHNIQUE FOR IMPROVING IRON DEFICIENCY TOLERANCE OF PLANT AND ENHANCING IRON AND ZINC ACCUMULATION IN EDIBLE PART THEREOF BY CONTROLLING EXPRESSION OF NOVEL IRON-ZINC BINDING CONTROL FACTOR
Abstract The present invention provides: a transformant and a gene-disrupted strain which grow better in a calcareous soil than common plants and can accumulate iron and zinc in a larger amount both in a calcareous soil and in a good soil; a gene, a vector, a protein and an antibody to be used for constructing the aforesaid transformant and gene-disrupted strain; a method for constructing a plant that has improved tolerance to iron deficiency and shows enhanced iron and zinc accumulation in an edible part thereof; a composition for constructing the aforesaid plant; a kit for constructing the aforesaid plant; and a breeding method. The protein according to the present invention, which comprises one of the following amino acids (a) to (c), is characterized by being an iron-zinc binding control factor: (a) an amino acid sequence represented by SEQ ID NO:1 or 2; (b) an amino acid sequence derived from the amino acid sequence represented by SEQ ID NO:1 or 2 by deletion, substitution or addition of one to several amino acids; and (c) an amino acid sequence that has an identity of 80% or greater with the amino acid sequence represented by SEQ ID NO:1 or 2.
Outline of related art and contending technology BACKGROUND ART
The plant is growing, in order to perform the substance production and carbon fixation, iron and zinc is required. Plants, the soil due to the absorption of iron and zinc, these are used. However, approximately 30% of the soil in the world occupies in calcareous alkaline soil, solubilized iron and zinc is small, even in the solubilized iron is extremely small. Thus, growth of the plants in the soil of the calcareous alkali, iron deficiency is a major limiting factor for. Therefore, calcareous alkaline soil failure including the acquisition of the plants growing in soil is improved is an urgent need.
In addition, iron and zinc from the soil and the plants that were absorbed, human major mineral source. Iron deficiency and zinc deficiency is, people in the world, especially in children and therefore becomes a serious problem for women, edible part of plants containing a large amount of iron and zinc acquisition has been desired.
In recent years, iron and zinc absorption and use (especially iron) the identification of genes involved in advanced and analysis. A modification of the gene by introducing into the plant, iron and zinc deficiency resistance is improved on the plant, or, a large number of edible plant to accumulate iron and zinc are acquired (for example, see non-patent document 1-11).
