Ginseng (Panax genus) is one of the most medicinally important genera and consists of highly regarded medicines.
Among the species of Panax, the ginseng species is widely known to have most medicinal quality.
P. ginseng has 3 varieties, Jakyung, Chunggyung and Hwangsook, discovered in nature with different colors of stem and fruit.
Jakyung has two cultivars, Yunpoong and Chunpoong. Rigorous phylogenetic analysis of these varieties and cultivars has been conducted with sequencing of rDNA region.
The sequences of ITS1, ITS2 of every varieties and cultivars within P. ginseng were identical.
The sequence of 5.8S rDNA of Hwangsook variety were different from the sequences of 5.8S rDNAs of others by only one base pair at nucleotide position 14.
In phylogenetic analysis and predicted RNA secondary structure study, it is assumed that evolution has proceeded from Hwangsook to other varieties recently.
