Abstract |
|
Molecular phylogenetic studies were conducted to evaluate evolutionary trends, relationships and species identities among four species, one variety and one outgroup of the Korean Genus Calystegia. The important characteristics of Calystegia are the shape of the lamina, the length ofthe corolla and the presence of hair. However, many variations were observed as regards the characteristics of the leaf, making true identification difficult. In molecular phylogenetic studies, C. soldanella formed one clade, and it was located mostly in the base. C. hederacea and C. sepium did not form an independent clade in their ITS regions and psbA-trnH regions, and this investigation could not confirm a relationship. Therefore, a relationship between these two species is not sufficiently supported by these markers (ITS and psbA-trnH). Consequently, this research should be achieved through many samples and markers. C. sepium var. japonica and C. dahurica are closely related. |
