Protein OsCCT22 related to rice seed shattering and coding gene and application thereof

The invention discloses a protein OsCCT22 related to rice seed shattering as well as a coding gene and application thereof. The invention discloses a protein OsCCT22 related to rice seed shattering performance. The protein OsCCT22 is a protein of which the amino acid sequence is SEQ ID No.1. A CRISPR/cas9 gene editing method is utilized to edit the OsCCT22 gene in the rice to obtain an OsCCT22 gene edited strain, and the seed shattering of the rice mutant obtained after the OsCCT22 gene is edited is reduced, which shows that the OsCCT22 gene and the OsCCT22 protein thereof can regulate and control the seed shattering of the rice, and the seed shattering of the rice can be reduced by mutating the OsCCT22 gene and the OsCCT22 protein thereof. The method has a good application prospect. 本发明公开了一种与水稻落粒性相关的蛋白OsCCT22及其编码基因与应用。本发明公开的与水稻落粒性相关的蛋白OsCCT22为氨基酸序列是SEQ ID No.1的蛋白质。本发明利用CRISPR/cas9基因编辑方法对水稻中OsCCT22基因进行编辑，获得OsCCT22基因编辑株系，OsCCT22基因被编辑后所得水稻突变体的落粒性下降，说明OsCCT22基因及其OsCCT22蛋白质可以调控水稻的落粒性，可通过对其突变降低水稻的落粒性。本发明具有很好的应用前景。
