OsRUS1蛋白及其编码基因在控制水稻分蘖角度及分蘖数中的应用
摘要：
本发明公开了OsRUS1蛋白及其编码基因在控制水稻分蘖角度及分蘖数中的应用。该OsRUS1蛋白的氨基酸序列如SEQ ID NO.1所示，其编码基因如SEQ ID NO.2所示。本发明的发明人发现OsRUS1蛋白具有控制水稻分蘖角度及分蘖数的功能，其过量表达将导致株型松散，分蘖减少，稻穗变长。可通过对OsRUS1蛋白及其编码基因进一步研究水稻的分蘖机制或信号通路；也可以通过抑制或促进OsRUS1蛋白的表达量，得到株型松散或株型紧凑的水稻品种。
摘要（英）：

The invention discloses an OsRUS1 protein and an application of encoding genes thereof in control of tiller angle and tiller number of rice. The amino acid sequence of the OsRUS1 protein is shown as SEQ ID NO.1, and the amino acid sequence of the encoding genes of the OsRUS1 protein is shown as SEQ ID NO.2. The inventor finds that the OsRUS1 protein has a function of controlling the tiller angle and tiller number of rice, and according to overexpression, plant type looseness, tiller reduction and rice ear lengthening are caused. According to the OsRUS1 protein and the encoding genes thereof, the tillering mechanism or signal path of rice can be further researched; and rice varieties with loose or compact plant types can be obtained by inhibiting or promoting the expression quantity of the OsRUS1 protein.
