The genus Salix L. is represented by more than 500 species in the world where 27 species are naturally found in Turkey. This genus has been commonly used as biomass production for energy, phytoremediation and pharmacological products. The objective of this study is to estimate the haplotype frequency analysis of native willow species in Turkey. The sequence data are obtained from non-coding (trnL) and coding (matK and rbcL) cpDNA gene regions of Salix species (24 species and one hybrid). Results showed that all haplotype trees gave the similar outcomes separating haplotypes into two clusters (subgenera; Salix and Vetrix). The most diverse haplotype in matK region (23 haplotype) are identified in Turkish willows. Haplotype sharing was increased for both trnL and rbcL gene regions, but they were still high (13). Incomplete lineage sorting and introgressive hybridization are the phenomena that likely determine the haplotype composition of Turkish Salix sp. Haplotype sharing is common within the geographically close members of subgenus (Salix or Vetrix) but not between two subgenera of Salix. Anatolia’s varied regional and specific climate seem to create suitable environments for haplotype sharing within subg. Vetrix species (higher altitude and cooler climates) and within subg. Salix species (warmer climate). Furthermore, analysis of molecular variance (AMOVA) and pairwise Fst values for Turkish Salix species, Old World and New World Salix based on cpDNA matK and trnL gene regions revealed that the high variation within groups and differences between Turkish subgenera are consequences of contribution of OWS and NWS.

Phylogenetic analysis of the Turkish Salix species based on sequence data from chloroplast matK and nuclear ITS regions Acar, Pelin; Özdemir Değirmenci, Funda; Kaya, Zeki (null; 2016-01-13) The genus Salix L. is represented by more than 500 species in the world. About 28 species of these are naturally found in Turkey. This genus has been commonly used as biomass production for energy, phytoremediation and pharmacological products. The traditional methods for identifying the species based on morphology are insufficient to classify them due to hybridization, reproductive isolation, and polyploidy. The objective of this study was to reveal the phylogenetic relationships of native willow species i...
Genetic differentiation of Liquidambar Orientalis Mill. varieties with respect to matK region of chloroplast genome Özdilek, Aslı; Kaya, Zeki; Department of Biology (2007) Liquidambar L. genus is represented with mainly 4 species in the world and one of these species, Turkish sweet gum (Liquidambar orientalis Mill.) which is a relictendemic species is naturally found in only southwestern Turkey, mainly in Muğla Province. The limited distribution of species with two disputed varieties (var. integriloba Fiori and var. orientalis) and increased anthropogenic threats to its genetic resources signify the importance of studying genetic diversity in the species to have better conser...
Characterization of taxonomically related some Turkish oak (quercus l.) species in an isolated stand : a morphometric analysis approach Aktaş, Caner; Kaya, Zeki; Department of Biology (2010) The genus Quercus L. is represented with more than 400 species in the world and 18 of these species are found naturally in Turkey. Although its taxonomical, phytogeographical and dendrological importance, the genus Quercus is still taxonomically one of the most problematical woody genus in Turkish flora. In this study, multivariate morphometric approach was used to analyze oak specimens collected from an isolated forest (Beynam Forest, Ankara) where Quercus pubescens Willd., Q. infectoria Olivier subsp. boi...
Genetic Diversity Pattern of Salix alba Populations in a Fragmented River Ecosystem in Eastern Mediterranean Özdemir Değirmenci, Funda; Acar, Pelin; Kaya, Zeki (null; 2016-01-13) The genus Salix L. is represented with more than 500 species in the world and 28 of species are found naturally in Turkey. The species of the genus have been widely used for bioenergy and phytoremediation. Salix alba like many other willow species is with great renewable energy potentiali and important component of an healthy riparian ecosystem as an indicator species in major river ecosystems in Turkey. With this study, it was aimed to provide information for efficient conservation, management and util...
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...
