Outline of Final Research Achievements |
Gentian is a perennial plant and known as ornamental flowers. To reveal the mechanism of overwintering buds formation, we first evaluated the movement of GtFT1 protein from aerial- to underground- organ in gentian. However, we could not find the GtFT1 protein movement. Next, we performed expression analysis of overwintering buds. GtSOC1L was highly expressed in overwintering buds, whereas GtFLC was broadly expressed in overwintering buds. Moreover, Transgenic gentian plantlets expressing GtSOC1L showed excessive formation of overwintering buds compared to wild type. These results implied that the GtSOC1L play important role in the formation of overwintering buds in gentian.
