The genus willow (Salicaceae) has around 500 species worldwide, 27 species naturally distributed in Turkey. Goat willow (Salix caprea) is an ecologically important, cold tolerant pioneer species which spreads in Europe and western and central Asia, in the Mediterranean Sea, central Anatolia and Black Sea regions in Turkey. It is also naturally distributed through Coruh river banks. Hydroelectric dam plant dams are being built in these regions which endanger this species. Some of the Salix caprea populations would be under water in near future. Beside this, hydroelectric plants may change local climate which would affect Salix caprea negatively by increasing average annual temperature. Moreover, there have been genetic diversity studies in Europe about Salix caprea species by using SSR markers, but there has been no study related with genetic diversity assessment of this species in Turkey yet. Therefore, it is important to determine the genetic diversity of Salix caprea populations in the eastern Black Sea Region. To characterize genetic diversity of Salix caprea species, 180 genotypes were analyzed by using 10 microsatellite markers. The number of observed alleles ranged from 3.500 to 5.600 and average mean value was 4.770. The observed heterozygosity vi ranged from 0.082 to 1.000 and average mean value was 0.503 while expected heterozygosity ranged from 0.119 to 0.827 and average mean value was 0.538. % 7.5 genetic variation was between populations and % 92.5 genetic variations were within populations. When Salix caprea populations were evaluated according to their genetic relations, two separate groups were formed; one group included populations in the Trabzon region and the other group included populations in the Artvin region. In the current study, magnitude and pattern of genetic diversity of Salix caprea were determined successfully. Populations had moderate level of genetic diversity. Construction of dams in these regions might endanger genetic resources of Salix caprea in near future.

Pattern of genetic diversity in Turkey oak (quercus cerris l.) populations
Tümbilen Özer, Yeliz; Kaya, Zeki; Department of Biology (2014)
Quercus cerris L. is a native and widely distributed species in Turkey. It is an important element of Anatolian forests and with other oak species constitute 76.4% of broadleafed forests. However, there is little information on the genetic make-up of Turkish populations. In the current study, the genetic diversity of Q. cerris populations sampled within their natural range is assessed with microsatellite loci (SSRs) polymorphism. Thirteen populations were sampled from seven different locations. Four of thes...
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 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...
Assessment of genetic diversity in picea orientalis (l.) link. in genetic resources by microsatellites
Özdilek, Aslı; Kaya, Zeki; Temel, Fatih; Department of Biology (2015)
Picea comprises about 40 species in the world. One of these species, oriental spruce (Picea orientalis (L.) Link.) is naturally distributed in northeastern Turkey, mostly in Artvin Province and in a part of Georgia close to the coast of the Black Sea region. The limited distribution of species and increased anthropogenic threats to its genetic resources signify the importance of studying genetic diversity of the species to have better conservation and management programs. Here, we report the first high thro...
Haplotype frequency analysis of Turkish Salix L. (Salicaceae),
Kaya, Zeki (null; 2018-01-13)
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...
