Current Mutatome Of Sars-Cov-2 In Turkey Reveals Mutations Of Interest, Doğa Eski̇er, Evren Akalp, Özlem Dalan, Gökhan Karakülah, Yavuz Oktay
Turkish Journal of Biology
As the underlying pathogen for the COVID-19 pandemic that has affected tens of millions of lives worldwide, SARS-CoV-2 and its mutations are among the most urgent research topics worldwide. Mutations in the virus genome can complicate attempts at accurate testing or developing a working treatment for the disease. Furthermore, because the virus uses its own proteins to replicate its genome, rather than host proteins, mutations in the replication proteins can have cascading effects on the mutation load of the virus genome. Due to the global, rapidly developing nature of the COVID-19 pandemic, local demographics of the virus can be difficult …

Phylogenetic Analysis Of Peste Des Petits Ruminants Virus From Outbreaks In Turkey During 2008-2012, Leyla Güler, Murat Şevi̇k, Mustafa Hasöksüz
Turkish Journal of Biology
Peste des petits ruminants (PPR) is an important viral disease of sheep and goats and is endemic in all regions of Turkey. In this study, PPR virus infection was investigated by RT-PCR assay based on the fusion (F) gene in PPR-suspected sheep and goat samples. PPR virus RNA was detected in 65 small ruminants (51 sheep, 14 goats) from independent outbreaks during 2008-2012 in provinces in the central and Mediterranean regions and the central-west part of the Aegean region in Turkey. The virus was detected in an aborted sheep fetus sample by RT-PCR, and diagnosis was also confirmed by virus …

Y Chromosome Analysis Of Native Turkish Cattle Breeds By Microsatellite Markers, Yusuf Özşensoy, Ercan Kurar, Zafer Bulut, Mehmet Ni̇zamlioğlu
Turkish Journal of Biology
The aim of this study was to determine phylogenetic relationships of 6 native cattle breeds of Turkey using 7 Y chromosome-specific microsatellite DNA markers. DNA samples were isolated from Anatolian Black, Anatolian Grey, South Anatolian Red, Native Southern Anatolian Yellow, East Anatolian Red, and Zavot cattle using a standard phenol/chloroform method. PCR products were separated by capillary electrophoresis and marker genotypes were determined. A total of 41 different alleles were observed. The mean allele number was 5.86 and mean F_{IS} value was 0.427 for all populations. The INRA189 locus was monomorphic for all populations except for South Anatolian Red. UMN0307 …

Aging And Cancer: Molecular Facts And Awareness For Turkey, Gülgün Gündüz, Kayahan Fişkin
Turkish Journal of Biology
Two important subjects concerning extension of the human life-span are biological aging processes and their relationship to diseases, and especially to the formation of cancer. It is clear that an aging population poses some challenges for developing countries. We set out to show the demographic structure of Turkey and to discuss the feasibility of decreasing the prevalence of cancer. We overviewed the literature on the relationship between biological aging and cancer formation, the environmental causes of cancer, and age-related characteristics of cancer in the elderly. In addition, some statistical data on the changing demography of Turkey were reviewed. It is …

Turkish Journal of Biology
The villages of Ilıca District in Erzurum Province, Turkey, were surveyed in terms of plants and animals used traditionally for medicinal purposes. Plants were compiled according to their families, botanical names, local names, usages, and applications. A total of 70 plant species belonging to 29 families are used by village people to treat a wide range of complaints, such as hemorrhoids, urinary system infections, stomach disorders, respiratory diseases, skin diseases, rheumatism, and jaundice. In addition, 3 animal species are used for the treatment of some diseases. The collected data were compared with those formerly recorded.

Turkish Journal of Biology
The oil content and fatty acid compositions of 5 Bupleurum species (B. intermedium, B. lancifolium, B. croceum, B. rotundifolium, and B. cappadocicum) were determined. Their oil contents ranged from 2.87% to 4.20%. Gas chromatography (GC) was used for the fatty acid composition. Twenty-one fatty acids were identified and quantified by GC. Oleic acid (C18:1) accounted for more than 50% of the total fatty acids in 3 of the Bupleurum species (B. intermedium, B. lancifolium, and B. rotundifolium). The total unsaturated fatty acid contents varied from 67.28% in B. cappadocicum to 87.06% in B. rotundifolium. The total saturated fatty acids represent …

Determination Of Genetic Relationships Among Velezia L. Caryophyllaceae) Species Using Rapd Markers, İlham Eröz Poyraz, Emel Sözen, Ebru Ataşlar, İsmai̇l Poyraz
Turkish Journal of Biology
Random amplified polymorphic DNA (RAPD) markers were used to determine genetic relationships among Velezia L. species from Turkey. A total of 432 amplified bands were obtained using 14 RAPD primers. The polymorphism in RAPD markers was high (98.61%) and was sufficient to distinguish each species. The degree of band-sharing was used for evaluating the genetic similarity between species and for constructing a dendrogram by the unweighted pair group method with arithmetic mean (UPGMA). Genetic relationships among the species were found to be fully consistent with those obtained by the use of morphological characters. Data obtained from our study demonstrated that …

Calcium Oxalate Crystal Types In Three Oak Species (Quercus L.) In Turkey, Bedri̇ Serdar, Hati̇ce Demi̇ray
Turkish Journal of Biology
Crystal types from 3 oak species representing 3 different sections of the genus Quercus were identified. Crystals were studied with scanning electron microscopy after localisation by light microscopy. The crystals were composed of calcium oxalate silicates as whewellite (calcium oxalate monohydrate) composites. In Quercus macranthera Fisch. et Mey. subsp. syspirensis (C.Koch) Menitsky (İspir oak) from the white oaks (section Quercus: Leucobalanus), whewellite and trihydrated weddellites coexisted. Axial parenchyma cells included 30 crystal chains with walls as chambers in uniseriate ray cells; some cells had many crystals without any chambers and were small.

Turkish Journal of Biology
In the present study, a total of 290 actinomycetes isolates were obtained from 19 karstic caves in Turkey. Out of these, 131 were chosen for numerical classification studies according to their morphology and pigmentation properties. Representative isolates were compared with the reference Streptomyces strains based on their various taxonomic characteristics such as biochemical, physiological, nutritional, and morphological, totalling 134 unit characters. The data were evaluated using simple matching coefficients (S_{SM}), and clustering achieved using the Complete algorithm by X-Taxon and NTSys-pc programs. The test strains were assigned to 9 major (5-11 strains), 18 minor (2-4 strains), and 31 single membered …

Chromosomal Differentiation Between Populations Of Clarias Gariepinus (Burchell, 1822) From The Göksu Delta And Orontes River (Turkey), Arzu Karahan, Serap Ergene
Turkish Journal of Biology
The karyotype of Clarias gariepinus was described by means of G-banding, C-banding, Q-banding, and Ag-NORs (NORs) staining in this study. Samples were collected from 2 regions of Turkey: the Göksu Delta and Orontes River. Although samples from both regions had the same diploid chromosome number and fundamental arm number, (2n = 56, FN = 100), they had remarkable differences in karyotype formula and distribution of rDNA sites, according to silver nitrate staining and G-banding. While the karyotype formula for Orontes River samples was 24m + 10sm + 10st + 12a, the Göksu Delta samples' was 28m + 6sm + 10st …

Ultrastructure Of Spermatozoa From Domesticated Birds: Comparative Study Of Turkey, Chicken And Guinea Fowl, R. J. Thurston, R. A. Hess
Scanning Microscopy
Typical for non-passerine birds, the spermatozoa of the turkey, chicken and guinea fowl were vermiform with a maximum width of 0.5-0. 7μm and lengths of 90μm for chicken sperm, and 75-80μm for those of the turkey and guinea. An acrosome, nucleus, midpiece and flagellum could be distinguished by SEM.
The acrosomal cap projected over a perforatorium surrounded by granular material. At its base, the cap encircled apical projections of the nucleus. The nucleus consisted of dense chromatin, and formed a concave implantation fossa where it joined the midpiece of the tail. For turkey and chicken spermatozoa, the neck region of …
