bHLH148基因在调控番茄开花节位中的应用
By overexpressing the bHLH148 gene in tomato plants, constructing an overexpression vector, and screening for high-expression plants, the problem of an imperfect tomato flowering node regulation network was solved, resulting in a reduction in the initial flowering node and earlier flowering, which promoted the regulation of fruit yield and quality.

AI Technical Summary
Technical Problem
In existing technologies, the gene network regulating tomato flowering nodes is incomplete, making it difficult to effectively regulate the flowering time of plants, which affects fruit yield and quality.
Method used
By overexpressing the bHLH148 gene in tomato plants and constructing an overexpression vector, plants with increased bHLH148 gene expression were screened to regulate the flowering node of tomatoes.
Benefits of technology
This method has enabled tomato plants to lower the initial flowering node and advance flowering, providing a new direction for targeted improvement of plant flowering time and the market availability of mature fruits.

Abstract
本发明提供bHLH148基因在调控番茄开花节位中的应用，所述bHLH148基因的ORF序列如SEQ.NO.1所示，所述bHLH148基因编码的蛋白质氨基酸序列如SEQ.NO.2所示。通过在植株内过表达bHLH148基因可得到始花节位降低、开花提前的番茄植株；和野生植株相比，过表达bHLH148基因植株在始花节位表现出明显的降低，在第一花序现蕾时间上也表现出明显的提前。这一结果为定点改良植物开花节位，完成植株开花时间的调控及成熟果实的上市时间提供了一个新的技术方向。
