To investigate the phylogenetic relationships of Salvia euphratica sensu lato and its closely related species with a focus on the section Hymenosphace, we screened five different regions; one nuclear ribosomal DNA region (Internal Transcribed Spacer, ITS) and four chloroplast DNA regions [trnT-trnL intergenic spacer (IGS), trnL intron, trnL-trnF IGS and trnV intron]. Based on 19 sequences of 7 Salvia taxa produced in the study and different number of sequences obtained from GenBank, our results supported latest taxonomic treatments on Salvia pseudeuphratica and S. cerino-pruinosa as they are resurrected and accepted different species from S. euphratica. The results confirmed the latest phylogenetic findings as "the section Hymenosphace is a non-monophyletic group, originated thick textured, non-expanding ancestral group, and expanding calyces with widely diverging lips in fruiting stage evolved several times in parallel, not only in Salvia but also in the Iranian genus Zhumeria". The species of the sect. Hymenosphace are mostly distributed in three different geographic regions [(1) Southwest Asia, Turkey, Russia and Iran, (2) Canary Islands, (3) Southern Africa] with different morphological characters. The results showed that ITS had the highest resolution power for discriminating studied taxa and the highest number of haplotypes was also observed in this region. The resolutions of the chloroplast regions were too low for taxa native to Turkey, but quite enough to discriminate species from the different clades whose sequences were obtained from database.

A taxonomic revision of Salvia euphratica sensu lato and its closely related species (sect. Hymenosphace, Lamiaceae) using multivariate analysis
Kahraman, Ahmet; CELEP, FERHAT; Doğan, Musa; Bagherpour, Safi (2010-01-01)
As an initial part of a revisional study based on the genus Salvia L. (Lamiaceae), extensive field studies, herbarium and literature surveys, and multivariate analysis have been conducted on the basis of the Salvia euphratica sensu lato (S. cerino-pruinosa, S. euphratica, S. leiocalycina, and S. pseudeuphratica) and its closely related species (S. kronenburgii and S. sericeo-tomentosa) in order to understand their taxonomic status. For the multivariate analysis, 35 OTUs (Operational Taxonomic Units) represe...
A cytomorphological study in some taxa of the genus Salvia L. (Lamiaceae)
MARTİN, ESRA; Cetin, Ozlem; Kahraman, Ahmet; Celep, Ferhat; Doğan, Musa (2011-07-01)
The taxa of the genus Salvia L. (Lamiaceae) used in this study were collected from their natural habitats in Turkey. In this paper, the number, size and morphology of somatic chromosomes of 22 Turkish taxa of Salvia, namely S. bracteata Banks & Sol., S. fruticosa Mill., S. huberi Hedge, S. hydrangea DC. ex Benth., S. nemorosa L. and S. pomifera L. (2n=14), S. adenocaulon P.H. Davis and S. aucheri Benth. subsp. canescens Boiss. & Heldr., (2n=18), S. argentea L., S. frigida Boiss., S. palestina Benth., S. poc...
COMPARATIVE MORPHOLOGY, ANATOMY AND PALYNOLOGY OF TWO SALVIA L. SPECIES (LAMIACEAE) AND THEIR TAXONOMIC IMPLICATIONS
Kahraman, Ahmet; Celep, Ferhat; Doğan, Musa (2009-06-01)
Morphological, anatomical and palynological characteristics of Salvia glutinosa L. and S. staminea Montbret & Aucher ex Bentham and their taxonomic importance are presented. Their expanded description and phenology are also given. The features of stems, leaves, calyces, corolla and nutlets have been found to be significant to distinguish the species. Mesophyll structure, distribution of stomata on upper epidermis, size of stomata on lower epidermis, shape of vascular structure in midrib, and number of vascu...
A Numerical taxonomic study on the genus salvia l. (lamiaceae) in Turkey
Tiambeng, Deniz; Doğan, Musa; Department of Biology (2015)
Widely used a medicinal plant, Salvia L. is the largest genus in the family Lamiaceae, with over 1700 species found in Asia, Europe, Africa and the Americas. Within this genus, almost 100 species are recognized in Turkey. To date, however, no comprehensive infrageneric treatment of Salvia in Turkey exists. The objective of this study was to propose a more natural infrageneric classification of the genus Salvia in Turkey by using the numerical taxonomic approach developed by Sneath and Sokal in 1973. In this...
Molecular phylogenetic analyses of Juniperus L. species in Turkey and their relations with other junipers based on cpDNA
Güvendiren, Aysun Demet; Kaya, Zeki; Department of Biology (2015)
Evolutionary relationships within and among two sections and three subsections of Juniperus species (Section Juniperus, subsections Juniperus, Oxycedrus and Caryocedrus, Section Sabina) naturally distributed in Turkey were investigated with molecular variations of chloroplast DNA (cpDNA). This study revealed the phylogenetic relation of 66 individuals from 7 native Turkish Juniperus L. species based upon DNA sequence of trnL intron (trnL5’-L3’) , trnL3’- F(GAA) (trnL-F intergenic spacer), trnV intron and ma...
