源自甘薯的IbOr-Ins基因突变体及其用途
摘要：
本发明涉及在源自甘薯的IbOrange基因中人为地插入特定碱基序列的IbOr-Ins基因突变体；含有所述基因突变体的重组载体；转化所述重组载体的宿主细胞；将所述重组载体转化到植物细胞中，从而使类胡萝卜素含量或盐胁迫耐性得到增加的转化植物体的制备方法；由所述方法制备的类胡萝卜素含量或盐胁迫耐性得到增加的转化植物体及其种子；利用源自甘薯的IbOrange基因的盐胁迫耐性得到增加的转化植物体的制备方法；由所述方法制备的盐胁迫耐性得到增加的转化植物体及其种子。
摘要（英）：

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.
