促进提前开花的白桦BplSPL1基因及其编码蛋白
摘要：
本发明涉及一个促进提前开花的白桦BplSPL1基因及其编码蛋白,属于分子生物学中的基因技术领域，其特征在于促进提前开花的白桦BplSPL1基因的核苷酸序列如序列表SEQ ID NO:1所示；氨基酸序列如序列表SEQ ID NO:2所示。本发明提供白桦开花基因BplSPL1并用于构建BplSPL1基因的植物表达载体，构建的植物表达载体经农杆菌浸染拟南芥植株，获得转基因拟南芥植株并提早开花，表明该基因具有诱导拟南芥早花的功能并且能够调控植物叶的发育。本发明为利用基因工程技术调控白桦开花时间和叶片发育提供了基因资源与理论依据，具有很大的应用价值。
摘要（英）：

Belonging to the field of gene technology in molecular biology, the invention relates to a betula platyphylla BplSPL1 gene for promoting precocious flowering and an encoded protein thereof. The invention is characterized in that the betula platyphylla BplSPL1 gene for promoting precocious flowering has a nucleotide sequence shown as SEQ ID NO:1 in a sequence table, and has an amino acid sequence shown as SEQ ID NO:2. The invention provides the betula platyphylla flowering gene BplSPL1 and applies the gene to construction of a BplSPL1 gene's plant expression vector, and the constructed plant expression vector is subjected to agrobacterium impregnation of an arabidopsis thaliana plant so as to obtain a transgenic arabidopsis thaliana plant and achieve precocious flowering. Therefore, the gene has the function of inducing precocious flowering of arabidopsis thaliana and can regulate plant leaf development. The gene provided by the invention utilizes genetic engineering technology to regulate betula platyphylla flowering time and leaf development, provides gene resources and theoretical basis, and has great application value.
