The aim of this study was to make evaluation of existing structure of Plumbaginaceae in Turkey in order to see infrafamilial grouping as well as infrageneric arrangement of the big genera (Limonium and Acantholimon). For this purpose, numerical taxonomic method and clustering analysis were used. Also, this was the first time that all the genera of Plumbaginaceae found in Turkey were examined together, within the same study. Herbarium specimens of 61 species were evaluated on the base of 57 morphological characters to construct data matrix. Data matrix was analysed by Multi Variate Statistical Package (MVSP) software. First, Unweighted Pair Group Method with Arithmetic Mean (UPGMA) analysis was used to construct phenograms. Later, Principal Component Analysis (PCA) was performed to indicate which characters were the most significant for the outcome of the analysis. Obtained results were discussed, and compared with previous findings. According to UPGMA phenogram, the genera in our study were well separated from one another, exhibiting quite natural structure. Plumbago and Ceratostigma formed one cluster that correspond to the Plumbaginoideae subfamily. The other cluster analogous to subfamily Staticoidea was formed by Goniolimon, Limoniopsis, Armeria, Psylliostachys, Acantholimon and Limonium. Within genera Acantholimon and Limonium clusters equivalent to the main sections were observed. Furthermore, it was seen that our findings were largely supported the taxonomic treatments given in the Flora of Turkey and the subsequent revisional studies. Eventually, a new generic identification key for the Plumbaginaceae in Turkey including the newly recorded genus Psylliostachys is provided.

A new taxon of the genus Salvia (Lamiaceae) from Turkey
CELEP, FERHAT; Kahraman, Ahmet; Doğan, Musa (Botanical Garden Meise, 2011-01-01)
Background and aims Turkey is one of the major centers of diversity for Salvia, with 97 species of which 54% are endemic. The aims of this study are to give detailed taxonomical, morphological and ecological accounts of S. cadmica and S. smyrnaea.
ANALYSIS OF PLASMIDS MEDIATING ANT (2'') AND AAC(3)-II BASED GENTAMICIN RESISTANCE IN CLINICAL ISOLATES OF ENTEROBACTERIACEAE
Kocabıyık, Semra (Elsevier BV, 1989-07-01)
The genetics of ANT(2″) and AAC(3)-II mediated gentamicin resistance in Gram-negative bacteria obtained from Hacettepe University Hospital in Turkey, was studied. The plasmid DNA analyzed by agarose gel electrophoresis revealed a heterogeneous plasmid population. Conjugal transfer appeared to be an efficient mechanism for the dissemination of resistance to gentamicin/tobramycin/kanamycin/streptomycin/chloramphenicol/cephalothin, which was the common resistance pattern in the population. Plasmids of 46, 60, ...
A numerical taxonomic study of the genus Acantholimon Boiss Plumbaginaceae in Ankara Province Turkey
MUVAFFAK, Aslı; Doğan, Musa; Bilgin, Cemal Can (Laser Pages Publishing Ltd., 2001-01-01)
This study examines whether a satisfactory classification of Acantholimon Boiss. (Plumbaginaceae) species found in Ankara province (Turkey) can be obtained from phenctic clustering based on external vegetative and floral morphological characters of both herbarium and collected specimens, The study is on the following species: A. venustum Boiss., A, halophilium Bokhari., A. acerosum (Willd.) Boiss., A. kotschyi (Jaub. & Spach) Boiss., A. confertiflorum Bokhari., A. glumaceum (Jaub. & Spach) Boiss., A. casare...

The main aim of this study is to look for trends in the instructional technology field in Turkey and to visualize general tendencies in the field in research topics, research types, and methodologies. Content analysis research design was used in this study. In this study, the unit of analysis was MS theses and PhD. theses published in instructional technology departments in Turkey, and the researcher aimed to analyze all of the population. Hence, 215 MS theses and 32 PhD. theses were analyzed in this study....
Comparative molecular phylogenetics of Astragalus L. sections from Turkey with New World Astragalus species using nrDNA ITS sequences
Dizkirici, Ayten; EKİCİ, MURAT; Kaya, Zeki (Springer Science and Business Media LLC, 2014-01-01)
Comparative molecular phylogenetic study using nrDNA internal transcribed spacer region (ITS) sequences was carried out on species from three Astragalus L. (Fabaceae) sections from Turkey (Old World species) and the New World. A total of 56 taxa (179 accessions) including 30 species from Incani DC., 15 species from Hypoglottidei DC. and 11 species from Dissitiflori DC. section were used in the current study. The total length of the ITS region was 642 bp with 56 (8.7 %) parsimony-informative and 9 insertion\...
