[Phylogenetic relationships of the Far Eastern Araliaceae inferred from ITS sequences of nuclear rDNA].

In eight species of the family Araliaceae, inhabiting the territory of the Russian Far East, the sequences of ITS regions of nuclear rDNA were determined. A comparison of these sequences enabled establishment of phylogenetic relationships between the Far Eastern and other members of the family. It was demonstrated that Aralia sensu populations from Primorye and Sakhalin were genetically different and, hereby, could be classified as interspecific taxa. Aralia continentalis along with A. cordata were attributed to the section Aralia sensu. Oplopanax elaus and O. horridus were found to be very close to each other, possibly being the subspecies of one species or relatively young species. Legitimacy of the isolation of two sections within the genus Eleutherococcus was confirmed.
