| 摘 要： | 大豆是典型短日照植物,对光周期反应敏感。利用GmGBP1-i干涉植株与光周期反应敏感的大豆品种DN50为试验材料,通过短日照和长日照两种不同条件光周期处理,明确不同基因型大豆植株开花后光周期反应敏感性,同时分析其农艺性状。结果表明,不同光照条件下,GmGBP1干涉大豆植株均表现为植株矮小、节间距缩短、不同程度减产,且光周期反应敏感度较野生型低。说明GmGBP1基因在大豆生长、发育和生殖过程中具有重要作用。

| Abstract: | Soybean, a typical short day plant(SDP), was very sensitive to photoperiod response.This study used the GmGBP1-i interference plant and soybean variety DN50, which was sensitive to photoperiod as experimental materials, the short day and long day photoperiod treatments were carried to clarify the photoperiod response sensitivity after flowering, meanwhile, the agronomical characters were also analyzed. The results showed that the GmGBP1 interference soybean showed the phenotypes of smaller plants, shorter internode distance, different levels of yield loss, and decreased photoperiod sensitivity under different lighting conditions. It indicated that GmGBP1 played significant roles in the soybean growth, development and reproductive process. |
