Outline of Final Research Achievements

Some plants have underground stems called as rhizomes. Although many plants are known to have rhizomes, such as bamboo, potato and onion, the mechanism how they grow and adapt themselves to the environment remains unknown. It is interesting to know how rhizomes transport photosynthetic products by the regulation of the whole plant body. To analyze it, metabolomics analyses were performed by using wild grass, Oryza longistaminata. As a result, several metabolic products accumulated specifically in buds of rhizome depending on their development. This means some products transport through rhizomes and accumulate to generate new rhizome for their speedy propagation.
