OSIT GENE FROM ORYZA SATIVA FOR IMPROVING IRON AVAILABILITY OF PLANT AND USES THEREOF

摘要

The present invention relates to an Oryza sativa iron transporter (OsIT) which is an iron transporting gene derived from rice and is composed of a base sequence represented by sequence number 1. The present invention further relates to a method for increasing iron usability in plants in comparison with a non-transformant by transforming a plant cell through introducing a recombinant vector including the gene encoding OsIT protein thereto; a method for producing a transgenic plant in which the iron usability is increased in comparison with the non-transformant, by transforming the plant cell through introducing a recombinant vector including the gene encoding the OsIT protein; a transgenic plant in which iron usability is increased in comparison with the non-transformant produced by the method, and a seed thereof; and a composition for increasing iron usability in plants, containing, as an active ingredient, the gene encoding the OsIT protein composed of amino acid sequence represented by sequence number 2.
