| Research Abstract |
Bud dormancy is one of the survival strategies of perennials. Gentians produce overwintering buds, which have strong tolerance to cold, but the mechanisms regulating dormancy are unknown. In this study, we performed metabolome analysis and found that the concentrations of gentio-oligosaccharides were changed during dormancy. We also found the gene expression and activity of invertase were changed in parallel with the gentio-oligosaccharide concentration, implying that the oligosaccharides was regulated by invertase. Furthermore, targeted metabolome revealed that treatment of the oligosaccharides activated some metabolic pathways, indicating that gentio-oligosaccharides may be involved in regulation of dormancy in gentians
