Outline of Final Research Achievements

Plants of Ligularia were extensively studied in the Hengduan Mountains and adjacent areas. Many Ligularia species including L. fischeri were found to harbor high chemical diversity with geographic distributions. The chemical composition, morphology, and the base sequence of the ITS regions in the rRNA gene were analyzed to identify F1 hybrids and introgressed individuals. The results on them suggested that hybridization frequently occurs in Ligularia and that it is an important mechanism in the generation of chemical diversity. Intraspecific diversity was also recorded for Eupatorium heterephyllum and some other plants.
