一种大豆Dof17类转录因子GmDof17-1蛋白及其编码基因与应用
摘要：
本发明属于植物基因工程领域，公开了一种大豆Dof17类转录因子GmDof17-1蛋白及其编码基因与应用。一种大豆Dof17类转录因子GmDof17-1蛋白，具有SEQ ID NO.2所示的氨基酸序列，其编码基因GmDof17-1具有SEQ ID NO.1所示序列。利用植物表达载体，将本发明的GmDof17-1基因导入植物细胞，可获得高含硫氨基酸(甲硫氨酸与半胱氨酸)含量的转基因细胞系及转基因植株。本发明的GmDof17-1对培育高含硫氨基酸含量的植物品种特别是高含硫氨基酸含量的大豆，提高农作物特别是大豆的品质具有重要意义。
摘要（英）：

The invention belongs to the field of plant gene engineering and discloses a soybean Dof 17 transcription factor GmDof 17-1 protein as well as a coding gene and an application thereof. The soybean Dof 17 transcription factor GmDof 17-1 protein has an amino acid sequence shown by SEQ ID NO.2; and the coding gene GmDof 17-1 has a sequence shown by SEQ ID NO.1. By means of a plant expression vector,a transgenic cell line with high sulphur-containing amino acid (methionine and cysteine) content and a transgenic plant with high sulphur-containing amino acid content can be obtained by introducing the GmDof 17-1 gene in the invention into a plant cell. The GmDof 17-1 disclosed by the invention has important significance in culturing plant varieties with high sulphur-containing amino acid contents, in particular soybeans with high sulphur-containing amino acid contents, and improving the quality of crops, in particular the quality of soybeans.
