Ibor-Ins gene mutant from ipomoea batatas and uses thereof

Abstract

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. 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.

Description

technical field [0001] The present invention relates to the IbOr-Ins gene mutant derived from sweet potato and its use, and relates in more detail to the IbOr-Ins gene mutant artificially inserted into the specific base sequence in the IbOrange gene derived from sweet potato (Ipomoea batatas); The recombinant vector of the gene mutant; the host cell for transforming the recombinant vector; the method for preparing the transformed plant by transforming the recombinant vector into plant cells, thereby increasing the carotenoid content or salt stress tolerance; The carotenoid content or salt stress tolerance prepared by the above-mentioned method are increased transformed plants and seeds thereof; the preparation method of the transformed plants obtained by using the salt stress tolerance of the IbOrange gene derived from sweet potato is increased; the salt prepared by the method Transformed plants having increased stress tolerance and seeds thereof. Background technique [00...
