  New Record of the Melanopsis buccinoidea (Olivier, 1801) from two streams of Mersin (Türkiye) with Evaluation Some Morphometric Parameters

  Kocabaş, Mehmet; Kutluyer Kocabaş, Filiz

  In this study, some biometric characteristics of the freshwater snail Melanopsis buccinoidea (Olivier, 1801) were determined in Koca Stream and Bayat Stream (Mersin, Türkiye). Weight (W) (g), shell length (SL) (mm), shell width (SW) (mm), aperture length (AL) and width (AW) (mm) measurements were made on the samples taken from different stations. Morphological relationships were determined by multivariate statistical evaluation. The highest values in terms of shell length and weight were determined to be 16.53±3.67 mm and 0.47±0.23 g, living in Koca Stream. The largest shell length measured in the samples was 21.93 mm and the aperture width was 10.62 mm. The results were analyzed using Principal Component Analysis (PCA), a versatile statistical technique employed to explore the relationships between variables and account for a significant portion of the dataset. Samples taken from different stations showed a strong relationship between aperture width and spir height.

  Molecular Insight on Phylogeny and Systematics of the Narrowly Endemic Centaurea bingoelensis (Asteraceae)

  Yazdıç, Ferit Can; Açar, Mıkaıl; Cakilcioglu, Ugur; Tasar, Neslihan; Çelik, İbrahim Seyfettin

  Centaurea L. is a genus that is systematically discussed and whose taxonomic issues need to be clarified in the light of molecular techniques developed in recent years. This study aims to contribute taxonomically in molecular terms by studying the morphological and phylogenetic relationships of Centaurea bingoelensis. This limited, endemic species grows naturally in the Bingöl province of Türkiye. A phylogenetic analysis based on the molecular marker ITS, which is the most preferred in evolutionary studies and found in nuclear DNA, has been proposed as a molecular marker of C. bingoelensis , an endemic plant in Türkiye, and has not yet been molecularly identified. For this purpose, PCR amplification of the fragment mentioned above was performed, followed by direct sequencing, analysis of nucleotide variation, and phylogenetic analysis with different species. The Centaurea species identified so far have been shown to have three main distinct major clades and the specific phylogenetic methods used (NJ, ML, MP) and the ITS nucleotide sequences analyzed revealed a close phylogenetic relationship between C. bingoelensis and C. spectabilis. For a more accurate phylogenetic classification of this species within the Asteraceae family, their close relationships were probed using similar sequences from the GenBank Database. Phylogenetic analysis of C. bingoelensis specimens using ITS sequences reveals their position in the Asteraceae family and molecular support for these specimens being new species as proposed. Although morphologically similar to C. fenzlii and C. obtusifolia, the remarkable point of our study is that C. bingoelensis is phylogenetically closer to C. spectabilis. This work has exciting implications for understanding the evolution and diversification of the genus Centaurea. In addition, the results of this study show that the samples identified as Centaurea species in Türkiye are still not entirely determined genetically.

  Aydın, Sevinç; Karaca Sanyürek, Nesrin; Yaman, Hümeyra; Yılmaz, Ömer

  Traditional methods used to increase plant productivity from the past to the present cause problems owing to their toxicological effects on organism resistance and living things. This has stipulated the creation of strategies to boost plant productivity without adversely affecting the health of living things. Essential oils secreted from various parts of plants stand out as, sustainable, and improvable alternatives and have been the subject of numerous types of research as they have many functional properties. The present research covers the investigation of the allelopathic effect of essential oils of Greek Oregano (Origanum vulgare L. subsp. hirtum), Lavandin (Lavandula x intermedia), and common sage (Salvia officinalis L.) on oilseed plants (Cephalaria syriaca L., Camelina sativa L.) at different ratios. Inhibitory effects of the essential oils obtained by hydrodistillation on the seeds of Cephalaria syriaca L. and Camelina sativa L. species at different concentrations were analyzed under sterile in vitro conditions. The inhibitory effects of essential oils and concentrations were analyzed using the Friedman test. The research revealed that essential oils were effective in weed control through their high inhibitory effect against Cephalaria syriaca L. seeds while reducing the germination power of Camelina sativa L.

  Benzer, Fulya; Kandemir, Fatih Mehmet; Yildirim, Serkan; Coşkun, Pınar; Küçükler, Sefa

  This study was conducted to investigate the effects of chrysin (CH) on lead acetate (PbA) inducing liver injury. In this study, 35 male Sprague Dawley rats were divided into 5 groups as 7 rats in each group. Group 1 (Control): Saline was given orally. Group 2 (CH group): CH (50 mg kg-1 weight day-1 ) were orally given rats for 7 days. Group 3 (PbA group): PbA (30 mg kg-1 ) was orally given to rats at 30 mg kg-1 PbA for 7 days. Group 4 (PbA +CH 25 group): 25 mg/kg CH was orally given to rats for 7 days. In addition, 30 mg kg-1 PbA was given orally to rats for 7 days after 30 minutes of the application of the CH. Group 5 (PbA+CH 50 group): 50 mg kg-1 CH was orally given to rats for 7 days. Furthermore, 30 mg kg-1 PbA was given orally to rats for 7 days after 30 minutes of the application of the CH. The rats were euthanized under mild sevoflurane anesthesia and tissue and blood samples were taken 24 hours after the last application (8th day). AST, ALT and ALP in serum, MDA, GSH and NO levels and SOD, CAT, GPx and arginase enzyme activities in liver tissue were measured. Serum ALT, AST and ALP levels increased in the PbA group when compared with the control, and this increase was partially corrected with CH. Liver MDA and NO levels increased in the PbA administered groups while antioxidant enzyme activities and GSH levels decreased. Although, CH administration decreased the increased MDA and NO levels, it increased the decreased antioxidant enzyme activities and GSH levels. Histologically, it was determined that CH decreased the necrosis, hydropic degenerations and mononuclear cell infiltrations seen in the livers of rats treated with PbA. As a result, CH is effective in the reducing PbA damages in the liver.

  Genetic Diversity Analysis of Aydın/Turkey Dittrichia viscosa (L). Greuter (Asteraceae) Populations Using RAPD Markers

  Paksoy, Mehmet Yavuz; Sevindik, Emre; Uzun, Sefa

  In this study, we performed a genetic diversity using RAPD markers for some Dittrichia viscosa populations grown in the Aydın region of Turkey. Total genomic DNA isolation from the leaves of Dittrichia viscosa was performed using commercial kit. eight RAPD primers were used to determine genetic diversity among populations. Polymerase Chain Reaction (PCR) was performed with all DNA samples and primers with ability of scoreing band. PCR products were run in agarose gel and visualized under UV light. They scored as there were bands (1) and no bands (0) at all gel images and their files were created. A total of 50 characters were obtained from the primers. Phylogenetic relationships and genetic distances between the cultivars were calculated by using the PAUP* 4.0b10 analysis program. According to the PAUP data, the closest genetic distance was determined 0.20000 and between Central and İncirliova populations, the most distant genetic distance were determined 0.36842 between İncirliova and Koçarlı populations. In the phylogenetic analysis has been obtained using UPGMA algorithms and phylogenetic tree consist of two clades. The results also propose that RAPD markers are useful tools for indicating genetic relationships among Dittrichia viscosa populations.

  Assessment of Biomarkers of Oxidative Stress and Antioxidant in Wild and Farmed Çoruh trout (Salmo coruhensis) Spermatozoa

  Benzer, Fulya; Erişir, Mine; Kocabaş, Mehmet; Kutluyer Kocabaş, Filiz

  Behaviour and physiology in fish are affected from environmental factors. Particularly, habitat and culture environment in aquatic animals are essential for life stages. In this study, biomarkers of oxidative stress and antioxidant were compared in wild and farmed Çoruh trout (Salmo coruhensis) spermatozoa. In spermatozoa of Çoruh trout, lipid peroxidation (malondialdehyde), glutathione and enzymatic antioxidant activities (catalase, superoxide dismutase, glutathione peroxidase) were assessed. Our data demonstrated that superoxide dismutase (0.44±1.25 Umg-1 protein), catalase (15.21±4.69 k.g-1 protein), glutathione peroxidase (42.89±0.61 Ug-1 protein), glutathione (0.18±4.01 μmolg-1 cell) and malondialdehyde (2.49±0.12 nmol.g-1 cell) levels in wild fish were low compared to spermatozoa of farmed fish. Overall, alterations in malondialdehyde levels and the antioxidant status could be differences in habitat.
