Contribution to the phylogeny of Caucasian Nonea (Boraginaceae) inferred from nrDNA ITS and trnL-F data

Nonea (Boraginaceae) with nearly 35 species was divided into four sections based on the shape of mericarpids and the position of the anthers in the corolla tube. Although several comprehensive taxonomic studies have been performed on Turkish and European Nonea taxa, Caucasian ones have not been studied well. Therefore Caucasian Nonea need close attention with regard to molecular systematics. In this study, 15 Caucasian Nonea including N. cyanocalyx and N. bakuensis were evaluated with nrDNA ITS and cpDNA trnL-F sequence data using Maximum Parsimony and Bayesian Inference to reconstruct phylogeny. All examined members of Nonea were grouped at three main clades with weak to good support values based on nrITS and at two main clades with moderate to good support values based on trnL-F. Both trees did not coincide with the traditional sub-generic delimitation of Nonea, but nrITS tree supported monophyly of Nonea. On the other hand, Pulmonaria is deeply nested in Nonea in the trnL-F tree. Moreover, present findings support treating N. cyanocalyx and N. bakuensis as distinct species rather than subspecies and revealed a preliminary phylogenetic structure of little known Caucasian Nonea.

Scorzonera ahmet-duranii sp. nov. (Asteraceae) from southwest Anatolia, and its phylogenetic position

Scorzonera ahmet-duranii S. Makbul & Coskuncelebi sp. nov. (Asteraceae) is described and illustrated as a new species endemic to Turkey. It is morphologically similar to S. semicana DC., but differs by its rootstock, deeply undulating basal leaves and glabrous achenes. Additionally, the size and micro-morphological properties of achenes and some anatomical traits of the leaf and stem are helpful in distinguishing these closely related taxa. A phylogenetic analysis based on nrDNA ITS sequence data showed that S. semicana is the sister species of the new taxon presented in this study. © 2012 The Authors

Güney anadolu, Türkiye'den yeni bir Scorzonera (Asteraceae) türü ve moleküler verilere dayalı taksonomik durumu

Scorzonera zorkunensis Coskuncelebi & S.Makbul (Asteraceae) is described and illustrated from Turkey. It grows on serpentine in alpine steppe vegetation together with several endemic Scorzonera L. species in southern Anatolia at altitudes of 2075-2100 m. It is morphologically similar to S. pisidica Hub.-Mor., but it differs in its habit and stem and leaf pubescence. Additionally, the size and micromorphological characters of the achenes and some anatomical traits of the leaves, stems, and roots are helpful in distinguishing these closely related taxa. The phylogenetic analyses based on nrDNA ITS sequence data indicate that S. pisidica is a sister species of the new taxon. © TÜBİTAK
