- MakaleAçık Erişim2026Phylogenetic Analysis of Native Salmo Species in Türkiye Using Mitochondrial 12S rDNA, 16S rDNA, Cytochrome b Sequences, and Cytogenetics
Yazdıç, Ferit Can; Kar, Bülent; Karaman, Altuğ
In this study, phylogenetic relationships and genetic diversity of Salmo spp. populations in different water bodies in Türkiye were investigated, focusing on morphologically similar specimens to Salmo macrostigma. Significant genetic variability and evolutionary differentiation within these populations have been identified using mitochondrial regions sequences (12S rDNA, 16S rDNA, and Cyt-b), morphological observations, and cytogenetic analysis. Samples collected from eight river basins revealed three main phylogenetic clades and local adaptations influenced by ecological pressures. Cytogenetic findings showed that they have chromosome numbers ranging from 78 to 80 (2n), consistent with known Salmo species. For this purpose, three mitochondrial DNA fragments encoding 12S rDNA, 16S rDNA, and Cyt-b regions were amplified by PCR, sequenced, and then used for phylogenetic analysis of the studied species. The study revealed the need for comprehensive integrative taxonomic approaches to clarify the classification of Salmo spp. with critical implications for conservation strategies in Türkiye biodiversity hotspots. In conclusion, this study not only advances our knowledge of Salmo macrostigma or similar Salmo spp., but also suggests innovative approaches for future Salmonid phylogenetics and cytogenetics studies. The findings have important implications for understanding the evolution, taxonomy, and conservation of these economically and ecologically important fish.

Yazdıç, Fadime; Kar, Bülent; Karaman, Altuğ; Yücel, Halit; Ekinci, Kübra
Honey bees (Apis mellifera) are a unique super organism that produces products such as honey, pollen, royal jelly, propolis, beeswax and bee venom and serves as a vector for pollination of many natural and industriyal plants. The effect of intestinal microflora and, accordingly, the immune system come to the fore among the causes of colony losses that have occurred recently. The diversity and densities of bacteria in the digestive tube of bees are affected by their immune systems. In order for this effect to be positive, the intestinal microflora must be natural and balanced. The enzyme activity of the probiotic-derived Bifidobacterium sp., which has an important place among the bacterial populations in the intestine, has a critical effect on both other symbiont microorganisms and the nutrition of the host. Therefore, in this study, both glikozide hidrolase enzyme activity analysis and bibliometric analysis were performed to emphasize the importance of Bifidobacterium sp. Different pH, temperature and substrates were preferred to calculate the optimum enzyme activity. As a result of the analysis of the enzyme activity, the glycoside hydrolase activity (pH 5.0 and 30oC) of Bifidobacterium sp. was determined. Further use of inulin substrate has shown that it is a natural prebiotic source for this probiotic microorganism. At the same time, the hydrolysis of xylan, which is known as a new generation prebiotic source, has also taken place. For bibliometric analysis, correlation links in Web of Science and Scopus database were concluded with the help of VOS viewer software

Erten, Fusun
Maca (Lepidium meyenii) has been used as a dietary supplement in ethnomedicine for centuries.\rMaca has recently become a high-functional food globally, due to its numerous biological benefits.\rThe high-fat diet (HFD) is closely related to the occurrence of obesity. Obesity is a common cause\rfor chronic kidney disease. The aim of this study was to investigate the effects of maca on organic\ranion transporters-3 (OAT-3), organic cation transporter-1 (OCT-1), organic cation transporter-2\r(OCT-2), insulin receptor substrate-1(IRS-1), vascular adhesion molecule-1 (VCAM-1) and\rvascular endothelial growth factor (VEGF) protein levels. In the study, 28 Sprague-Dawley male\rrats were randomly allocated into four groups (n=7); i) Control group (fed with standard diet); ii)\rGroup fed with standard diet and supplemented with Maca (40mg/kg/day) group; iii) Group fed a\rHFD; iv) Group fed with Maca+HFD. After the 60-day of study, kidney OCT-1, OCT-2 and IRS-1\rprotein levels showed a significant increase in the HFD+Maca treated group compared to the HFD\rgroup (P<0.05). Renal OAT-3 level was found to be significantly lower in the HFD group compared\rto the control group (P<0.0001). In addition, a significant decrease in VCAM-1 and VEGF protein\rlevels was observed in the HFD+Maca group compared to the HFD group (P<0.0001). These\rresults show the protective and regulatory activity in the Maca's kidney tissue when both normally\rand the HFD diet is fed

In this study, genetic relationship of ISSR markers of seven endemic Inula species distributed in\rTurkey was carried out. Plant samples were collected from different regions of Turkey in 2013 and\rgDNA was obtained by DNA isolation from green leaves. Genetic relationship between species was\rdetermined using 12 ISSR primers. PCR products were run on agarose gel electrophoresis and\rvisualized under UV light. All gel images were examined and the presence and absence of\rpolymorphic bands were scored as 0 and 1. A total of 85 bands were obtained from the primers. Of\rthese, 74 polymorphic and 11 monomorphic bands were obtained. The total polymorphism rate was\rfound to be approximately 87.05%. The phylogenetic tree and genetic distances between species\rwere calculated using the PAUP 0 4.0b10 analysis program. According to the distance matrix, the\rgenetic distance was found between the closest Inula helenium subsp. orgyalis and Inula helenium\rsubsp. vanensis (0.29851), while the farthest between Inula sarana and Inula macrocephala\r(0.56000) species. The phylogenetic tree was obtained using the UPGMA algorithm, and the tree\rconsisted of two groups. The results were compared with the morphological, palynological nrDNA\rand cpDNA results of the past. Our findings supported previous studies

Kizak, Volkan; Türel, Murat; Güner, Yusuf; Kayim, Murathan
The aim of this study was to compare growth, gonadal structure and red blood cell sizes of triploid and diploid brown th trout (Salmo trutta fario). Triploidy was induced by providing a heat shock treatment to the fertilized eggs. From the 18month post-fertilization triploid (TBT) and control diploid (CBT) brown trout groups were investigated up to 32 nd month. Survival, specific growth rate, feed conversion ratio, condition factor, relative growth rate, absolute growth rate, gonadosomatic index, hepatosomatic index and carcass yield were determined in both groups. It has been determined that the triploid fish showed greater live weight than diploid fish despite the difference was not significant (P>0.05). In triploid group triploidisation success was obtained as 95% and male/female ratio was found as 44.4-55.6%. The red blood cells were significantly larger in triploids than diploid ones (P<0.05). Regarding histological section of gonads, triploidy resulted in reduced gonadal development in female, while triploid males seem to exhibit normal gonadal development. Our results suggest that since triploid females could grow more than males, the growth performance studies on triploid brown trout should be performed with all-female stocks under fish farming practices especially for the production of large size trout.
