摘要：
The present invention relates to a method for producing: an IbOr-Ins gene mutation in which a certain sequence is artificially inserted into an Ipomoea batatas-derived IbOrange gene; a recombinant vector including the gene mutation; a host cell mutated by the recombinant vector; and a transformed plant body that has an improved carotenoid content and resistance to saline stress by means of the mutation of the recombinant vector in a plant cell. The present invention also relates to a method for producing a transformed plant body having increased resistance to saline stress using the transformed plant body or seeds thereof produced by the above method and having an improved carotenoid content and resistance to saline stress, and using an Ipomoea batatas-derived IbOrange gene. The invention also relates to a transformed plant body produced by the above method and having increased resistance to saline stress, and to the seeds thereof.
