Molecular phylogenetic position of Turkish abies (pinaceae) based on noncoding trn regions of chloroplast genome

Özdemir Değirmenci, Funda
Abies is the second largest genus of family Pinaceae (after Pinus), consisting of about 51 species, all native to the Northern Hemisphere. There are six native taxa belonging to this genus growing in pure and mixed stands in Turkey. Abies cilicica subsp. isaurica, Abies nordmanniana subsp. bornmülleriana, Abies nordmanniana subsp. equi-trojani, Abies x olcayana are endemic and considered as lower risk (LR) species. To determine the genetic relationships in Turkish firs, 18 populations of different subspecies of Abies were collected from different regions of Turkey and non-coding trn regions of chloroplast DNA were sequenced to assess the genetic structure of the studied species. trnL, trnF and trnV region were examined. All the trn regions of Abies species in the world (aproximately 300 species that found in the IPNI (The International Plant Names Index) were investigated in the database of NCBI. The available trn sequences of 23 Abies species worldwide included into the analyses. All analyses to estimate molecular diversity parameters were carried out with the MEGA software. The constructed phylogenetic tree with the trn sequences revealed that Turkish firs formed a monophyletic group with almost no sequence divergence. v Since sequence data for all three sectors of trn were not available from the NCBI data base, the phylogentic analysis with the sequence data of trnL regions were compartively analyzed in all firs. The results showed that Turkish- European species formed a single clade, which clearly differentiated them from the others, such as Japanese species, A. veitchii. Similarly, according to the sequence data of trnF, Turkish fir species were grouped together and distinctly separated from Asian-American Fir species. The results suggest that all Turkish firs may have evolved from single ancestral fir species, most likely from Abies nordmanniana.


Molecular phylogenetics of Turkish Salix L. species
Acar, Pelin; Kaya, Zeki; Department of Biology (2017)
Chloroplast (trnT-F, matK and rbcL) and nuclear genome (ITS) regions were used to explore the evolutionary relationships of Salix species which are native to Turkey. Morphological analysis with the utilization of Principal Component Analysis (PCA) was also carried out. Such a combined sequence data from cpDNA and nrDNA genes enabled reliable subgenus-level classification of Turkish willows (subgenus Salix and Vetrix). Morphological and genetic results agree with traditional taxonomic concepts in clustering ...
Molecular phylogenetics of Turkish Abies (pinaceae) species based on matK gene regions of chloroplast genome
Ateş, Mevlüde Alev; Kaya, Zeki; Department of Biology (2011)
Pineacea is the largest family of conifers that includes 51 species of Abies which is the second largest genus after Pinus. There are six native taxa in Turkey belonging to this genus. Four of these taxa (Abies cilicica subsp. isaurica, Abies nordmanniana subsp. bornmülleriana, Abies nordmanniana subsp. equi-trojani, Abies x olcayana) are endemic and considered as low risk (LR) species according to the IUCN criteria. To determine the phylogenetic relationship in Abies spp. in Turkey, 18 populations of diffe...
The phylogenetic analysis of picea orientalis populations from northeastern Turkey with respect to non-coding trn and matk regions of chloroplast genome
Gülsoy, Ali Murat; Kaya, Zeki; Department of Biology (2011)
The genus Picea is located from temperate to Taiga (boreal) regions of northern hemisphere from subtropical to high altitude with 34 species. Picea orientalis is endemic to Eastern Black Sea Mountainous region of Turkey and Western Caucasus. To determine the genetic relatedness within Picea orientalis populations, as well as the relationship between other Pinaceae species from database, populations were sampled from 15 different locations within the natural range of species and grouped into 5 depending on s...
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...
Genetic relationships among perennial and annual Cicer species growing in Turkey as revealed by allozymes
Sudupak, MA; Kence, Aykut (Springer Science and Business Media LLC, 2004-05-01)
Allozyme polymorphisms were used to assess genetic variation and relationships among ten Cicer species ( annuals and perennials) growing in Turkey. Using seven enzyme systems, 12 putative scorable loci were detected and surveyed for polymorphism in an accession collection including wild and cultivated forms. Variation was generally low within accessions and species, but common between species. Cluster analysis based on the pairwise genetic distance coefficients (Nei 1978) among accessions and species using ...
