GmGIS3a基因在调控大豆株高和开花时间中的应用
By overexpressing the GmGIS3a gene, the plant height and flowering time of soybeans were regulated, which solved the problems of lodging and late flowering of tall soybeans, and achieved dwarfing of plant height and early flowering, thus improving lodging resistance and yield.

Abstract
本发明属于生物技术领域，具体公开了一种GmGIS3a基因在调控大豆株高和开花时间中的应用。所述GmGIS3a基因的序列如SEQ ID NO.1所示，GmGIS3a基因编码的氨基酸序列如SEQ ID NO.2所示。本发明利用pTF101载体过表达大豆GmGIS3a基因，转化大豆栽培品种Wm82，获得稳定的过表达植株，研究发现该过表达植株与野生型植株相比株高变矮，开花时间提早，说明GmGIS3a基因参与调控植物高度、开花时间的生物学过程。对于培育矮化且开花时间提前的植物新品种提供一种新的育种途径，在植物育种技术领域应用前景良好。
