获自功能型苹果的MsSUT4蛋白及其编码基因和应用
摘要：
本发明公开了一种获自功能型苹果的MsSUT4蛋白及其编码基因和应用。本发明提供了一种蛋白质，命名为MsSUT4蛋白，是如下(a1)或(a2)：(a1)由序列表中序列1所示的氨基酸序列组成的蛋白质；(a2)将序列1的氨基酸序列经过一个或几个氨基酸残基的取代和/或缺失和/或添加且与植物总类黄酮含量相关的由序列1衍生的蛋白质。编码所述MsSUT4蛋白的基因也属于本发明的保护范围。本发明还保护所述MsSUT4蛋白的应用，为如下(b1)或(b2)：(b1)调控植物的总类黄酮含量；(b2)增加植物的总类黄酮含量。本发明发现了MsSUT4蛋白及其功能，可用于培育总类黄酮含量改变的转基因植物，在植物育种中具有重大应用前景。
摘要（英）：

The invention discloses MsSUT4 protein from a functional apple and an encoding gene and application of the MsSUT4 protein. The MsSUT4 protein is protein formed by an amino acid sequence shown in a sequence 1 in a sequence table or protein which is obtained after the amino acid sequence in the sequence 1 is subjected to substitution and/or deletion and/or addition of one or more amino acid residues, related to the total flavonoid content of plants and derived from the sequence 1. The invention further provides the gene for encoding the MsSUT4 protein and application of the MsSUT4 protein. The MsSUT4 protein is applied for regulating and controlling the total flavonoid content of the plants and increasing the total flavonoid content of the plants. The MsSUT4 protein and functions thereof are found, and the MsSUT4 protein can be used for cultivating transgenic plants of which the total flavonoid content is changed and has an important application prospect in plant breeding.
