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 of two subgenera. Two coding cpDNA gene regions (matK and rbcL) are found as conserved whereas non-coding cpDNA (trn T-F) and nrDNA (ITS) evolved rapidly for Turkish Salix. Turkish willow species appear to be a monophyletic (cpDNA) or potentially monophyletic (nrDNA) with having two well supported clades. Biogeographically, subg. Vetrix species are located in high altitude and cool climate whereas subg. Salix species are in warmer climate. S. acmophylla is always located at distant positions of subg. Salix clade. The appearance of the subg. Vetrix members (S. rizeensis and S. amplexicaulis) in subg. Salix clade can be explained by occurrence of natural hybrids with species from subg. Salix in shared habitat. New World (America) and Old World (Asia) Salix species are scattered throughout Turkish subgenera in all phylogenetic trees. The close molecular relations between subg. Salix-OWS and subg. Vetrix-NWS were determined by taxonomical relations, rather than geographical distribution. Turkish subgenera were diverged from others in late Pliocene. Chloroplast introgression and incomplete lineage sorting events in Salix species of Turkey may explained the high haplotype diversity in the genus.

Evolutionary relationships among Astragalus species native to Turkey
Dizkırıcı, Ayten; Kaya, Zeki; Department of Biology (2012)
Evolutionary relationships within and among three Astragalus sections (Incani DC., Hypoglottidei DC., and Dissitiflori DC.) that were native to Turkey were inferred from variations of nucleotide sequences of both chloroplast and nuclear genome regions. In the current study, Fifty-six species included in the three Astragalus sections were utilized to figure out phylogenetic relationships and estimate evolutionary divergence time based on DNA sequence of trnL intron (trnL5’-L3’) , trnL3’-F(GAA) (trnL-F interg...
Molecular phylogenetic position of Turkish abies (pinaceae) based on noncoding trn regions of chloroplast genome
Özdemir Değirmenci, Funda; Kaya, Zeki; Department of Biology (2011)
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 subspecie...
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...
Cutting edge: Role of toll-like receptor 9 in CpG DNA-induced activation of human cells
Takeshita, F; Leifer, CA; Gursel, I; Ishii, KJ; Takeshita, S; Gürsel, Mayda; Klinman, DM (The American Association of Immunologists, 2001-10-01)
Unmethylated CpG motifs present in bacterial DNA stimulate a rapid and robust innate immune response. Human cell lines and PBMC that recognize CpG DNA express membrane-bound human Toll-like receptor 9 (hTLR9). Cells that are not responsive to CpG DNA become responsive when transfected with hTLR9. Expression of hTLR9 dramatically increases uptake of CpG (but not control) DNA into endocytic vesicles. Upon cell stimulation, hTLR9 and CpG DNA are found in the same endocytic vesicles. Cells expressing hTLR9 are ...
Molecular phylogenetic analysis resolving the taxonomic discrepancies among Salix L. species naturally found in Turkey
Acar, Pelin; Değirmenci, Funda Ö.; DUMAN, HAYRİ; Kaya, Zeki (2022-01-01)
Detailed phylogenetic relationships and molecular dating are still quite rare for the complex and diverse genus Salix L. Here we focus on the taxonomic status and phylogeny of twenty-six Salix taxa naturally found in Turkey using the chloroplast DNA regions (trn T-F, matK, and rbcL) to unravel the relationship among them. The status of Salix species was also checked in the phylogenetic tree constructed with the data from Internal Transcribed Spacer (ITS) region of nuclear gene, including 158 accessions from...
