IBOR-INS GENE MUTANT FROM IPOMOEA BATATAS AND USES THEREOF

摘要

PURPOSE: An IbOr-Ins mutant gene having specific nucleotide sequences inserted into IbOrange gene is provided to enhance carotenoid content and to develop a transgenic plant with salt stress tolerance. CONSTITUTION: An IbOr-Ins mutant gene is prepared by inserting a specific nucleotide sequence into Ipomoea batatas-derived IbOrange gene and has a base of sequence number 2. A method for producing a transgenic plant with enhanced carotenoid content comprises a transforming a recombinant vector containing IbOr-Ins mutant gene into plant cells and overexpressing IbOr-Ins mutant gene. A composition for enhancing carotenoid content of a plant contains the IbOr-Ins mutant gene.
