植物种子粒重相关蛋白GmGA20ox2及其编码基因与应用
摘要：
本发明公开了一种植物种子粒重相关蛋白GmGA20ox2及其编码基因与应用。本发明提供的蛋白质，来源于大豆，命名为GmGA20ox2蛋白，是如下(a)或(b)：(a)由序列表中序列1所示的氨基酸序列组成的蛋白质；(b)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/或添加且与植物种子粒重相关的由序列1衍生的蛋白质。编码所述GmGA20ox2蛋白的基因(命名为GmGA20ox2基因)也属于本发明的保护范围。本发明还保护一种培育转基因植物的方法，是将所述GmGA20ox2基因导入目的植物中，得到种子粒重和/或种子百粒重和/或种子千粒重高于所述目的植物的转基因植物。本发明对于提高植物籽粒产量具有重大的应用价值。
摘要（英）：

The invention discloses a plant seed grain weight-associated protein GmGA20ox2 and its coding gene and use. The plant seed grain weight-associated protein is derived from soybeans, is named as protein GmGA20ox2 and is (a), a protein with an amino acid sequence shown in the formula 1 in the sequence table or (b), a protein which is derived from the amino acid sequence shown in the formula 1 through replacement and/or deletion and/or addition of one or more amino acid residues in the formula 1 and is related to plant seed grain weight. The invention discloses a gene (named as gene GmGA20ox2) for coding the protein GmGA20ox2. The invention provides a method for cultivation of a transgenic plant. The method comprises introducing the gene GmGA20ox2 into an object plant to obtain a transgenic plant with seed grain weight and/or seed hundred-grain weight and/or seed thousand-grain weight higher than those of the object plant. The plant seed grain weight-associated protein GmGA20ox2 has a great application value of plant seed grain yield improvement.
