title: Taxonomic status of Atocion hypanicum (Klokov) Tzvelev (Caryophyllaceae) inferred from analysis of ITS1 and ITS2 secondary structure
abstract: Secondary structures of ITS1 and ITS2 transcripts of Atocion hypanicum (Klokov) Tzvelev and A. compactum (Fisch. ex Hornem.) Tzvelev were reconstructed. The presence of a unique nucleotide substitution in fourth helix of A. hypanicum ITS1 transcript, which lead to a disturbance in the secondary structure of the helix, strongly supported it as a separate operational taxonomic unit. The lack of CBC in obtained sequences of ITS2 from A. hypanicum and A. compactum confirmed the absence of genetic ba
