Outline of Final Research Achievements |
Higher plants belonging to different geographical populations within a single species were collected, and their chemical ingredients were analyzed using LC-MS and then exhaustively separated. The presence of intra-specific diversity in chemicals was revealed in some species. Of these, Eupatorium heterophyllum was classified into three groups based on their major components, which corresponded to the result of clustering of neutral DNA sequences. Calluses were successfully induced from intra-specifically diverse plants for studying a relationship between culture conditions and secondary metabolite profiles.
