Notes on its ecology and conservation status are presented. A distribution map for the new species and its closest allies in Turkey is provided.Öğe Antioxidant, antimicrobial activities and total flavonoid contents of Cirsium bulgaricum DC. leaf extracts(Marmara Univ, Fac Pharmacy, 2015) Karasakal, Ayça; Demirci, Ahmet Şükrü; Demirok, Nazan Tokatlı; Cabi, EvrenIn this study, the antioxidant activities of methanol and acetone extracts of Cirsium bulgaricum DC. (Asteraceae) were evaluated by five antioxidant assays, including phosphomolybdate method, cupric ion reducing capacity (CUPRAC), 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonicacid)/persulfate) ABTS/Persulfate, N,N-dimethyl-pphenylenediamine (DMPD) and a Ce(IV)-based reducing capacity (CERAC) methods. The 80% methanol and acetone extracts showed 0.005-6.16 +/- 0.03 mmol/g and 0.004-5.02 +/- 0.02 [(trolox (TR), catechin (CT), epicatechin (EC), rutin (RT), quercetin (QR), naringin (NG) in CUPRAC and ABTS/Persulfate methods, respectively]. According to DMPD methods, inhibition effect were showed 2.3%+/- 0.02 for 80% methanol and 4.6%+/- 0.07 for acetone. Ascorbic acid equivalent mmol (AA)/g extract in CERAC method was found to be 0.0834 +/- 0.09 for 80% methanol and 0.5622 +/- 0.05 for acetone. Ascorbic acid equivalent mu g ascorbic acid (AA) / mL extract were found 807.6 +/- 0.07 for 80% methanol and 292.4 +/- 0.01 for acetone in phpsphomolybdate method. In the addition to the antioxidant activity of the extract, the total flavonoid content was measured. Total flavonoid content of 80% methanol and acetone extracts was found to be 105.5-645 +/- 0.04 mu g/ml quercetin and rutin equivalent. For the determination of antibacterial activities Escherichia coli (E. coli) ATCC 25922, Escherichia coli(E. coli) O157:H7 ATCC 33150, Salmonella Enteritidis(S. Enteritidis) ATCC 1 3 0 7 6, Listeria monocytogenes(L. monocytogenes) ATCC 7 6 4 4, Staphylococcus aureus(S. aureus) ATCC 25923 bacteria were used as test bacteria. Acetone extracts showed antibacterial activity against all of the tested bacteria ranged between 17.00 +/- 1.72-19.88 +/- 1.75 mm and 80% methanol extracts showed antibacterial activity against all of the tested bacteria ranged between 11.35 +/- 1.43-14.43 +/- 1.32 mm.Öğe Arbuscular mycorrhizae inoculation of einkorn wheat affects fatty acid, nutrient and mineral concentrations(Universidade Federal do Rio de Janeiro, 2020) Ayaşan, T.; Kader Esen, V.; Kader Esen, V.; Eseceli, H.; Cabi, EvrenThe purpose of this study was to determine the effect of arbuscular mycorrhizae (AM) inoculation, which was administered to increase the quality of einkorn wheat in its fatty acid composition, quality and mineral concentration. Wheat grown from AM inoculated seed (AM+) had increased the dry matter (DM), iron (Fe), monounsaturated fatty acids (MUFA), especially oleic acid, and alpha-linolenic acid, and cis-5,-8,-11,-14, and cis-17 eicosapentaenoic acid from polyunsaturated fatty acids (PUFA) (P <0.05), but decreased crude ash (CA), potassium (K), and total saturated fatty acids (UFA), especially myristic acid, palmitic acid, stearic acid and monounsaturated fatty acids, especially cis-palmitoleic acid, cis-10-heptadecenoic acid, cis-11 eicosenoic acid, erucic acid, and linoleic acid (P <0.05) compared with einkorn wheat grown from non-inoculated seed (AM-). Crude protein (CP) content ranged from 10.56% to 10.68%, and ether extract (EE) content varied between 2.03% and 2.41%, neither of which was significantly different between treatments. Significant increases were observed in UFA, and in the ratios of UFA to SFA and PUFA to SFA in AM+ compared with AM © 2021.

Puccinelliinae), Poinae, Alopecurinae superclade, Miliinae, and Avenulinae and Phleinae (Poaceae, Pooideae, Poeae)(Wiley, 2022) Soreng, Robert John; Gillespie, Lynn Judith; Boudko, Ekaterina A.; Cabi, EvrenWe conducted a biogeographic analysis of the PPAM clade of Poeae Plastid DNA Group 2, which includes 12 subtribes of C-3 grasses. One hundred and eighty-four species sampled represent 42 of 43 accepted genera and taxonomic diversity in large genera. We analyzed plastid sequences of matK, trnC-rpoB, and trnT-trnL-trnF using BEAST to produce a dated tree and MrBayes to produce a Bayesian tree, on which we ran Bayesian-Binary-Markov-Chain analyses on a worldwide biogeographic data set of 12 areas. PPAM split in southwestern Asia into subtribe Coleanthinae and PAM clades in the Early Miocene. PAM diversified rapidly in the Middle Miocene in southwestern Asia into four monogeneric lineages, Avenulinae, Phleinae, Miliinae, Poinae, and the Alopecurinae superclade (seven subtribes with 27 genera). In the Late Miocene, Pliocene, and mostly Pleistocene, the latter four lineages diversified and dispersed across Eurasia and established in North America. Dispersals to the southern hemisphere occurred in the Pliocene and Pleistocene. Annuals occur in 15 Mediterranean and southwestern Asia genera, but in few genera in other regions. Beyond phylogenetically isolated annual species dating to the Miocene, all other annuals evolved in the Pliocene and Pleistocene. Cold tolerance is high among perennial species, many occurring in the alpine, nine genera ranging into the Arctic. We suggest that alpine and subalpine habitats were ancestral. High tolerance of saline and alkaline conditions arose between the Pliocene and Pleistocene in Coleanthinae, Alopecurinae, Poinae, Hookerochloinae, Beckmanniinae, and Arctopoa. Combinations are proposed for Cornucopiae alopecuroides in Alopecurus and for Paracolpodium colchicum in Hyalopodium. A nothogenus x Catanellia is proposed for Catabrosa x Puccinellia.Öğe Corchorus olitorius L. (Jute) leaf and seed extracts exerted high antibacterial activity against food and plant pathogenic bacteria(Sciendo, 2022) İşeri, Özlem Darcansoy; Körpe, Didem Aksoy; Şahin, Feride İffet; Cabi, Evren; Haberal, MehmetAim of this study was to comparatively evaluate antibacterial activities of methanol (MetOH), acetone (Ace), petroleum ether (PE) and aqueous (dw) leaf (L), root (R), and seed (S) extracts of Corchorus olitorius L. on both food- and plant-borne pathogens, with DPPH radical scavenging activities (DRSA), and quantitative and qualitative constituent analysis. Leaf PE has the highest strain susceptibility on both food- and plant-borne pathogens. Clavibacter michiganensis, Pseudomonas tomato, and Erwinia caratovora were susceptible to nearly all the leaf and seed extracts. Very low minimum inhibitory concentration (8-128 mL(-1)) and minimum bactericidal concentration (32-2048 mu g mL(-1)) were determined for both leaf and seed extracts against C. michiganensis. Total phenolic contents were correlated to DRSA. The phenolic compounds tested were higher in the leaf MetOH, cholorogenic acid being the most abundant one. Palmitic acid was determined in leaf PE and seed PE extracts. Results presented here demonstrate high antibacterial activity of C. olitorius leaf seed extracts against phytopathogens for the first time, and provide the most comprehensive data on the antibacterial activity screening against food-borne pathogens. Considering limitations in plant disease control, antibacterial activities of these extracts would be important in plant disease control.Öğe Determination of antioxidant, antimicrobial activities, total phenolic and flavonoid contents of Allium rumelicum, Jurinea kilaea and Peucedanum obtusifolium(2023) Karasakal, Ayca; Kilic, Orhan; Demirok, Nazan Tokatli; Cabi, EvrenA microwave-assisted extraction (MAE) process for polyphenols from Allium rumelicum Kocyigit & Ozhatay, Jurinea kilaea Azn. and Peucedanum obtusifolium Sibth. & Sm. was used. This research examined the methanolic extracts made from these three species’ antioxidant, antimicrobial, total phenolic, and flavonoid contents. By using the 2,2-diphenyl-1-picryl-hydrazyl-hydrate free radical method (DPPH), ABTS/Persulfate, and Cupric reducing antioxidant capacity (CUPRAC) methods, the total antioxidant activities and capacities were examined. Additionally, the Folin-Ciocalteu and AlCl3/KAc techniques were used to calculate the total phenolic and flavonoid contents. To ascertain the antibacterial capabilities of plants, the disc diffusion method was applied. The J. kilaea showed the greatest total antioxidant capacity/activity levels when measured using the CUPRAC and ABTS/Persulfate techniques. A. rumelicum was found to have the highest quercetin concentration, while P. obtusifolium had the lowest. In J. kilaea, the gallic acid concentration was highest. The highest antimicrobial activity values were obtained in P. obtusifolium.Öğe Determination of polycyclic aromatic hydrocarbons in the soil, atmospheric deposition and biomonitor samples in the Meric-Ergene River Basin, Turkey(Springer, 2020) Hanedar, Asude; Güneş, Elçin; Kaykıoğlu, Gül; Çelik, Suna Özden; Cabi, EvrenIn this study, the levels of polycyclic aromatic hydrocarbons (PAHs) were determined in various components in the Meric-Ergene River Basin which is one of Turkey's intensive industrialization centers and which accordingly has faced significant environmental pollution and has about 1300 industrial plants within its boundaries. In the river basin, 16 USEPA PAHs were measured in a total of 192 samples consisting of soil, lichen, pine needle and total deposition samples for 1 year to represent the four seasons at a total of 12 points in 4 different regions which were determined as intensive industrial area, industrial + residential area, agricultural area and background. According to the results obtained, the total PAH values, in all sampling points, varied between 69.6 and 1277.7 ng/g (dry wt) for soil, lichen and pine needle samples and between 0 and 937.8 ng/m(2)-day for the total deposition samples. The highest values were determined in the fall season for the lichen samples and industrial area. The data obtained were evaluated in terms of spatial and seasonal variations, and according to their molecular weights. The incremental lifetime cancer risks (ILCRs) of exposing to soil PAHs were calculated, and maximum ILCR values were observed in industrial areas for child and adults. The diagnostic ratios were performed for determining the source, and the comparison of bioindication features was made for lichen and pine needle samples by comparing with Koa and Kow values of PAHs.Öğe Determination of terrestrial EUNIS habitat types of Mount Ganos (Işıklar), Tekirdağ, Türkiye(2022) Demir, Ogün; Kızılırmaklı, Aybüke; Bozdağ, Cavit Meriç; Cabi, EvrenIn this study, it is aimed to determine the terrestrial European Union Nature Information System (EUNIS) habitat types of Mount Ganos (Işıklar) and its surroundings. Field studies were carried out from April to October 2021. Reference areas were determined for Maximum Likelihood (ML) classification during the field studies. To increase the accuracy and obtain the highest possible level of EUNIS habitat types, we used both reference areas observed in the field studies and processed land cover and habitat maps. These are; Landsat Satellite Images classified with ML, Corine Land Cover, and European ecosystem maps. Regarding both biodiversity and social activities, Mount Ganos is among the most significant natural areas in the Tekirdağ district. The northern slopes of the mountain have a rainier and more humid climate than the southern slopes which Mediterranean climate is dominant. The presence of various climate types and the remarkable altitude variations also contribute to the habitat diversity of the Mount Ganos. Many natural areas have been degraded due to anthropogenic effects such as mineral extraction, agricultural, tourism, and urbanization activities in the Mount Ganos region until today. In this study, a total of 9 ecosystems and 29 habitat types were determined for Mount Ganos according to the EUNIS classification. 21 of them were identified at level 3 and 8 of them ranged between 2 and 6 levels. The intensive unmixed crops (I1.1) are the most-covered EUNIS habitat type with 16173.16 hectares. This is followed by low and medium altitude hay meadows (E2.2, 9350.63 ha), Meso- and eutrophic Quercus, Carpinus, Fraxinus, Acer, Tilia, Ulmus, and related woodland (G1.A, 7548.73 ha) and Pseudomaquis (F5.3, 5926.65 ha). With this study, a portrait of the habitat destruction created by humans has also been drawn. The results of this study can be used by decision-makers to conserve the remaining natural habitats on Mount Ganos.Öğe Determination of the effects of salt stress in spinach by MRI and CT imaging techniques(International Society for Horticultural Science, 2019) Deveci, Murat; Arın, Levent; Cabi, Evren; Özçağlayan, Ömer; Doğru, M.The research was carried out to determine the changes occurred on the spinach leaf tissues as a result of salt stress by using MRI (Magnetic Resonance Imaging) and CT (Computed Tomography). In study which were used the ‘Meridien F1’ and ‘San Moreno F1’ as plant material, plants were grown in hydroponic system including Hoagland nutrient solutions under controlled conditions. For this purpose, the cultivars were grown in a climate chamber at 22/18°C (day/night) temperature, 70% relative humidity, 10/14 h (light/night) photoperiod and under 400 µmol m-2 s-1 light intensity conditions. Salt applications have been started at the period which plants had 4-5 true leaves and continued until harvest. The salinity of the nutrient solution in the pot was set up with NaCl. Trial were established as randomized plots design with 3 replications and at each replication consisted of two varieties and (‘Meridien F1’ and ‘San Moreno F1’) cultivars and 4 different salt concentrations [(EC = control (2), 6, 8 and 10 dS m-1)] were applied. Imaging studies were performed with MRI (magnetic resonance imaging) and CT (computed tomography). MRI images were obtained by taking coronal and axial reference planes of the leaves using T1 weighted (T1W) C + and proton weighted (PDW) sequences in GE Healthcare Brand (General Electric, UK) 1.5 Tesla MR device. In CT imaging, General Electric (UK) the Bright Speed Model with 16 detectors device was used. Sections taken at 0.625 mm diameter, 80 kV and 10 mA values following the angio protocol were examined and then with the help of postprocess multiplanar and volume rendering observations, the images were obtained. The most developed leaves of 3 plants at harvesting period were chosen and examined for the study. According to the observations of MRI and CT images, it was determined that the leaf texture of ‘Meridian F1’ against salt stress was less deformed than the leaf texture of ‘San Moreno F1’ and at the same time, the water transmission of ‘Meridian F1’ was better than ‘San Moreno’. By this research, it was shown that the damage caused due to salt stress could be determined in the early period by using MRI and CT imaging. © 2019 International Society for Horticultural Science.

It was found that AM inoculation of EW seed before sowing caused significant increases in crude protein (CP), ether extract (EE), neutral detergent fibre (NDF), zinc (Zn), copper (Cu), and iron (Fe) levels of straw, and a (P <0.05) decrease in crude ash (CA), metabolizable energy (ME), and organic matter digestibility (OMD) compared with the straw of non-inoculated EW. The observed difference in the average GP among the between EWS from plants grown from inoculated seed and those from the untreated control was significant at all times between the third and 96th hour. However, when the GP kinetics of the groups was examined after 96 hours' incubation, only the difference in the gas amount of the easily soluble fractions of feeds was significant. The GP from the slowly fermented part, the GP rate constant and the potential GP of the straws were not affected by the AM inoculation (P >0.05). Thus, inoculation of einkorn wheat with AM altered the nutritional value of the straw produced creating a roughage with decreased value for feeding ruminant livestock. © 2020, South African Bureau for Scientific Publications.Öğe Effect of freeze-dried kefir culture inoculation on nutritional quality, in vitro digestibility, mineral concentrations, and fatty acid composition of white clover silages(Springer Heidelberg, 2022) Esen, Selim; Cabi, Evren; Koç, FisunIn this investigation, the aim was to examine the impact of freeze-dried kefir culture (KC) on fermentation characteristics, aerobic stability, nutritive value, in vitro digestibility, some micro- and macronutrient concentration, and fatty acid (FA) composition of white clover (WC) silages. White clover silages were either uninoculated (Con) or inoculated with KC at the following application rates: 10 mg/kg (K10), 50 mg/kg (K50), 100 mg/kg (K100) on a fresh basis, and ensiled in laboratory-scale silos for 270 days, followed by 5 days of aerobic exposure. Changes in fermentation characteristics and nutritive value, in vitro digestibility and gas production (GP), mineral concentrations, and FA composition were assessed in terminal silages. The results showed that KC could effectively reduce neutral detergent fiber, hemicellulose, and ammonia-N contents. The increased acetic acid content of KC-treated silages improved aerobic stability. Freeze-dried kefir culture made no significant difference in cumulative GP and estimated parameters except for 48 and 72 h. It is evidently clear from the findings that KC reduced the K, Na, Se, and B concentrations of WC silages, whereas Ca, Zn, and Fe concentrations increased. In addition, KC significantly increased the proportion of saturated FA (SFA) in WC silages, whereas the proportion of polyunsaturated FA (PUFA) decreased. However, KC did not significantly affect the monounsaturated FA proportion of WC silages. Overall, it is concluded that adding 50-100 mg/kg of KC on a fresh basis is appropriate to improve the nutritional value of WC silages.Öğe Festuca albomontana (Poaceae), a new chasmophytic fescue from the Western Taurus Mountains (Antalya, Turkey)(Univ Zagreb, Fac Science, Div Biology, 2022) Aykurt, Candan; Cingay, Burçin; Sümbül, Hüseyin; Gülben, Mertcan; Cabi, Evren; Öz, ZeynepA new species of Festuca from the Western Taurus Mountains (Antalya, Turkey) is described here and named F. albomontana. The new species can clearly be distinguished from the other species included in the F. alpina group by its leaf anatomical features. It has a geographically isolated position in the Western Tauruses whereas a closely related species, F. sommieri, is very local in the Black Sea Region of Turkey. It is suggested that it should be in the critically endangered threat category according to the International Union for Conservation of Nature (IUCN) criteria. Observations on the ecology of the population are noted.Öğe First Trials of Genome Analyses in Some Onobrychis Species using Dot-Blot and Genomic in situ Hybridization Techniques(2024) Yücel, Gülru; Kolano, Bozena; Cabi, Evren; Tuna, MetinThe origin and genome composition of tetraploid cultivated Onobrychis viciifolia (2n = 4x = 28) were analyzed using dot-blot and genomic in situ hybridization (GISH) techniques. Dot-blot hybridization was used to find a genomic affinity between O. viciifolia and 16 diploid Onobrychis species. The hypothesis on the origin of the O. viciifolia was tested using GISH. Dot-blot analyses suggested a genomic affinity between O. viciifolia and four diploid Onobrychis species (O. kachetica, O. supina, O. pallasii, and O. vaginalis). Hybridization signals were observed on O. viciifolia chromosomes when gDNA of O. kachetica, O. supina, O. pallasi, and O. hypargyrea were used as probes. However, the observed chromosomal distribution of hybridization signals did not resemble GISH results. The observed signals colocalized with 35S rDNA or dispearse signals on all chromosomes were observed depending on the probe. Further investigations using more comprehensive and comparative analysis with both coding and repetitive DNA regions may provide a better understanding of the genome composition and evolution of O. viciifolia.Öğe Flow Sitometri ile Çok Yıllık Buğdaygil Yem Bitkisi Genetik Kaynaklarının Karakterizasyonu(2016) Savaş Tuna, Gülsemin; Keleş, Hüseyin; Göçmen, Damla; Güleryüz, Vesile; Nizam, İlker; Cabi, Evren; Tuna, MetinÇok yıllık buğdaygil yem bitkisi türlerinin morfolojik olarak birbirlerine çok benzemeleri, aralarında kolaycamelezlenerek hibrit türler oluşturabilmeleri ve doğal varyasyon sebebiyle teşhislerinde ciddi sorunlaryaşanmaktadır.

Methods: Crude n-hexane, diethyl ether, ethylacetate and methanol extracts from whole plants was used the determination of antiradical and antibacterial activity in C. creticum and compared in terms of extracts efficiency. Results: EC50 values of DPPH activity in different solvents revealed significant differences similar to TPC content. The lowest inhibitory effect was found to be Gram negative for E. coli, despite the highest inhibitory effect against Gram positive S. aureus. Conclusion: Antiradical and antimicrobial activity results presented that C. creticum, could be evaluate in food supplements and pharmaceutical industry as natural compound, and future investigations will be aimed the isolations of biologically active compounds to define individual active components.Öğe High-antibacterial activity of Urtica spp. seed extracts on food and plant pathogenic bacteria(Taylor & Francis Ltd, 2013) Korpe, Didem Aksoy; İşeri, Özlem Darcansoy; Şahin, Feride İffet; Cabi, Evren; Haberal, MehmetThe aim of this study was to comparatively evaluate antibacterial activities of methanol (MetOH) and aqueous (dw) leaf (L), root (R) and seed (S) extracts of Urtica dioica L. (Ud; stinging nettle) and Urtica pilulifera L. (Up; Roman nettle) on both food- and plant-borne pathogens, with total phenolic contents and DPPH radical scavenging activities (DRSA). MetOH extracts of leaves and roots of U. dioica had the highest DRSA. Extracts with high antibacterial activity were in the order Up-LMetOH (13/16) > Ud-SMetOH (11/16) > Up-SMetOH (9/16). Results obtained with Up-SMetOH against food spoiling Bacillus pumilus, Shigella spp. and Enterococcus gallinarum with minimum inhibitory concentrations (MICs) in 128-1024 mu g/ml range seem to be promising. Up-SMetOH also exerted strong inhibition against Clavibacter michiganensis with a considerably low MIC (32 mu g/ml). Ud-SMetOH and Up-LMetOH were also effective against C. michiganensis (MIC 256 and 1024 mu g/ml, respectively). Ud-SMetOH and Ud-RMetOH had also antimicrobial activity against Xanthomonas vesicatoria (MIC 512 and 1024 mu g/ml, respectively). Results presented here demonstrate high-antibacterial activity of U. pilulifera extracts and U. dioica seed extract against phytopathogens for the first time, and provide the most comprehensive data on the antibacterial activity screening of U. pilulifera against food-borne pathogens. Considering limitations in plant disease control, antibacterial activities of these extracts would be of agricultural importance.Öğe In Situ and in Vitro Nutritive Value Assessment of Styrax Officinalis L. as an Alternative Forage Source for Goat Feeding(Ankara Univ, Fac Agr, 2022) Esen, Selim; Koç, Fisun; Özdüven, Levent; Eseceli, Hüseyin; Cabi, Evren; Karadağ, HarunThe current study aimed to determine Styrax officinalis L. (SO) leafs nutritive value, collected at four phenological stages, pre-flowering (PF), flowering (FL), seed linkage (SL), and fruiting (FR) by in situ and in vitro experiments. The ruminal degradability of dry matter (DM) and crude protein (CP) and in vitro gas production (GP) of SO leaves were measured using three rumen fistulated mature Saanen goats. Significant differences between chemical compositions of the SO leaves collected at different phenological stages were observed (P<-0.001). The DM, CP, ether extract (EE), and ash values of SO leaves ranged between 29.16 to 45.63%, 10.11 to 19.79%, 3.40 to 5.85%, and 4.71 to 6.49% during the different phenological stages (PF, FL, SL and FR, respectively). Cell wall components of SO leaves showed a cubic trend due to their capability to form new shoots after grazing. The effective DM and CP degradability of SO leaves ranged between 66.91 to 77.93% and 64.92 to 84.57%. which means an average value for animals fed at approximately maintenance level when rumen outflow rate (r) is equal to 0.02 h(-1). Significant differences between the SO leaves collected at different phenological stages were observed in GP at all incubation times (P<-0.05 and P 0.001). After 96 h incubation, the gas produced ranged between 20.68 to 27.53 mL/200 mg DM of the substrate. The research findings clearly indicate that degradability of DM, CP, and ME content of SO leaves ranged between moderate to high and significantly affected by phenological stages, however, they could be utilized until the end of the FL stage as forage sources.
