CADMIUM ABSORPTION REGULATION GENE, PROTEIN, AND RICE PLANT HAVING REDUCED CADMIUM ABSORPTION

摘要

Provided are: a transporter gene involved in the promotion or inhibition of the absorption of Cd by a root; a mutant gene of the transporter gene; a transporter protein of the transporter gene; a rice plant of which the absorption of Cd is reduced; and a method for selecting and growing a rice plant of which the absorption of Cd is reduced. A gene encoding a transporter protein involved in the regulation of the absorption of cadmium, which comprises a DNA nucleotide sequence represented by SEQ ID NO: 2; a gene encoding a transporter protein involved in the regulation of the absorption of cadmium, which comprises a DNA nucleotide sequence represented by SEQ ID NO: 3; a gene encoding a transporter protein involved in the regulation of the absorption of cadmium, which comprises a DNA nucleotide sequence represented by SEQ ID NO: 4; and a transporter protein involved in the regulation of the absorption of cadmium, which comprises an amino acid sequence represented by SEQ ID NO: 1.
