Öğe Alkanna malatyana (Boraginaceae), a new species from East Anatolia, Turkey(Magnolia Press, 2014) Yildirim, Hasan; Senol, Serdar GokhanAlkanna malatyana (Boraginaceae) is described as a new species to science. It is endemic to the eastern Anatolia region of Turkey. A. malatyana is an obligated chasmophytic species, which colonizes on limestone rocky cliffs, known from a single locality in Levent Canyon, located in Malatya Province. It is related to A. mughlae and it shows some morphological similarities with A. confusa and A. kotschyana, but it clearly differs from them based on the morphological differences presented in the species description. In addition, the conservation status, a distribution map, and notes on the biogeography and ecology of the new species are given.Öğe Antimicrobial and antioxidant properties of Artemisia L. species from western Anatolia(Tubitak Scientific & Technical Research Council Turkey, 2012) Erel, Sura Baykan; Reznicek, Gottfried; Senol, Serdar Gokhan; Yavasogulu, Nefise Ulku Karabay; Konyalioglu, Sibel; Zeybek, Ahmet UlviArtemisia L. taxa (A. absinthium L., A. arborescens L., A. campestris L., A. scoparia Waldst. & Kit., A. santonicum L., and A. vulgaris L.) naturally distributed through western and southwestern Turkey were chosen as experimental materials in this study. Essential oils of the aerial parts of these Artemisia species were isolated by hydrodistillation and analyzed by gas chromatography-mass spectrometry. The major components were identified as sabinene in A. absinthium (17.56%), camphor in A. arborescens (33.39%), 1,2-dehydro acenaphthylene in A. campestris and A. scoparia (20.71% and 11.80%, respectively), and a-thujone in A. vulgaris and A. santonicum (56.13% and 39.46%, respectively). Essential oils and methanolic extracts of the plants were tested for antimicrobial activity using the disk-diffusion method against 8 bacteria and 1 fungus. Staphylococcus aureus was the most sensitive bacteria to all of the essential oils. A. santonicum and A. scoparia were the most active plants against Candida albicans, with 35-mm and 40-mm diameter zones, respectively. Antioxidant capacities of the plants were also tested. The radical scavenging activity of A. scoparia extract (48.51%) and essential oil (80.08%), the Trolox equivalent antioxidant capacity of A. campestris extract (10.76 +/- 0.47), and the a-tocopherol equivalent of A. absinthium extract (5.87 +/- 0.17) were the highest results.Öğe Campanula alisan-kilincii (Campanulaceae), a new species from eastern Anatolia, Turkey(Tubitak Scientific & Technical Research Council Turkey, 2014) Yildirim, Hasan; Senol, Serdar GokhanCampanula alisan-kilincii Yildirim & Senol (Campanulaceae) is described and illustrated as a new species from Malatya Province in eastern Anatolia, Turkey. The new species belongs to the section Rupestres, based on morphological features. It is morphologically similar to Campanula quercetorum and C. strigillosa but clearly differs from them based on the morphological differences presented in the species description. In addition, the conservation status, the distribution map, and notes on the biogeography and ecology of the new species are given.Öğe Ekimia ozcan-secmenii (Apiaceae), a new species from Southwest Anatolia, Turkey(Tubitak Scientific & Technical Research Council Turkey, 2018) Senol, Serdar Gokhan; Eroglu, Volkan; Pelit, Nazh Bahar; Bozyel, DuyguEkimia ozcan-secmenii Senol & Eroglu sp. nov. (Apiaceae) is described from SW Turkey. E. ozcan-secmenii differs from its close affinity, E. bornmuelleri, by life form (monocarpic), petal and bracteole morphology, and mericarp features. These data were more supported by the results of nrDNA ITS sequences. The ML tree depicted based on phylogenetic studies aimed to reveal the closeness of the Laserpitium and Prangos species as well as the location the affinity of species in the genus Ekimia. The taxonomic situation of Prangos hulusi was also evaluated based on nrDNA ITS sequences. Since E. ozcan-secmenii is distributed in Sami Soydam Sandalcik hydroelectric power plant in Acipayam, Denizli, the population is threatening by flooding. Therefore, conservation programs are urgently recommended.Öğe Helichrysum x kani-isikii (Asteraceae), a new nothospecies from Turkey(Magnolia Press, 2021) Semiz, Gurkan; Senol, Serdar Gokhan; Gunal, Batikan; Cicek, Mehmet; Eroglu, VolkanIn this study, Helichrysum x kani-isikii (Asteraceae), a new natural hybrid of H. compactum and H. unicapitatum from Babadag (Denizli, Turkey), is described and investigated in detail for the first time. The new nothospecies is similar to H. compactum and H. unicapitatum, but it has some intermediate morphological and palynological properties that position it between the two putative parents. In the diagnosis of the hybrid, pollen size and shape were found as significant characteristics. Taxonomic, morphological, and palynological characteristics of H. x kani-isikii are compared with those of its putative parents, and some other details are presented with notes on the IUCN category and ecology of the nothospecies. In addition, a key to diagnosing the hybrid from its parental taxa is also provided.Öğe Heterostyly in Linum aretioides(Tubitak Scientific & Technical Research Council Turkey, 2013) Guvensen, Aykut; Secmen, Ozcan; Senol, Serdar GokhanThe petal width; sepal, pistil, and stamen lengths; and changes in pollen sizes associated with heterostyly of different morphs in populations of Linum aretioides Boiss. were investigated. Fruit sets were compared in 2 populations and it was investigated whether the Bozdag population has a heteromorphic incompatibility system. It was observed that the stamen lengths of thrum morphs of Bozdag were shorter than those of thrum morphs of Babadag. Pistil lengths of both morphs of Bozdag were longer than those of morphs of Babadag. Pollen shapes of both morphs were prolate-spheroidal and subprolate, respectively, in the Bozdag population and subprolate in the Babadag population. It was determined that pollen exine in the short-styled and long-styled flowers was dimorphic. The pollen bore a marginal ring of 4 to 8 spinules in the thrum morphs and of 3 to 7 spinules in the pin morphs. It was found that the highest rates of fruit set occurred during cross-hand pollination from pin morphs to thrum morphs and from thrum morphs to pin morphs (77.77% and 71.42%, respectively). It was shown that in L. aretioides self-pollinations and pollinations between plants of the same morph are incompatible.Öğe Heterostyly in Linum aretioides(Tubitak Scientific & Technical Research Council Turkey, 2013) Guvensen, Aykut; Secmen, Ozcan; Senol, Serdar GokhanThe petal width; sepal, pistil, and stamen lengths; and changes in pollen sizes associated with heterostyly of different morphs in populations of Linum aretioides Boiss. were investigated.

A total of 392 AFLP markers were detected using 14 primer combinations. The number of polymorphic bands per AFLP primer combination ranged from 16 to 42, with an average of 28. The Polymorphism Information Content (PIC) values varied from 0.25 (M-CTC/E-AGC) to 0.72 (M-CAC/E-AAG) among 14 selective primers. The genetic dissimilarity that was detected using the NTSYS-PC software ranged from 0.09 to 0.82. According to the dissimilarity results, a high level of genetic diversity existed among the studied genotypes. A model-based structural analysis revealed the presence of 2 populations. The defined population structure was helpful when studying the S. tmolea genotypes for diversity and classification.Öğe IN VITRO SEED GERMINATION OF CYCAS REVOLUTA THUNB(Bangladesh Botanical Soc, 2017) Demiray, Hatice; Dereboylu, Aylin Esiz; Yazici, Zekiye Isin; Bildik, Simay; Bulbul, Nadir; Senol, Serdar Gokhan; Pirhan, Ademi FahriGermination of Cycas revoluta zygotic embryo and calli production from endosperm of seeds were succeeded in Litz medium which contains major salts of B5 (Gamborg et al. 1968) and minor and organic salts of MS media (Murashige and Scoog 1962). The induction medium covers organic compounds such as glutamine, arginine and asparagine in a variety of combinations including 2.4-D and Kn as well. The best medium for Cycas revoluta zygotic embryos is that with 10 mu M 2.4-D and 4.5 mu M Kn in which both zygotic embryos germinated healthily and green calli grew from endosperms of megagametophytes.Öğe New triterpene saponins from Phryna ortegioides(Elsevier Science Bv, 2015) Horo, Ibrahim; Masullo, Milena; Falco, Antonia; Senol, Serdar Gokhan; Piacente, Sonia; Alankus-Caliskan, OzgenFour new and three known oleanane-type saponins have been isolated from the methanolic extract of Phryna ortegioides, a monotypic and endemic taxon of Caryophyllaceae. The structures of the new compounds were determined as gypsogenic acid 28-O-beta-D-glucopyranosyl-(1 -> 2)-O-beta-D-glucopyranosyl-(1 -> 6)-O-beta-D-glucopyranosyl ester (1), 3-O-alpha-L-arabinofuranosyl-gypsogenic acid 28-O-beta-D-glucopyranosyl-(1 -> 3)-O-[beta-D-glucopyranosyl-(1 -> 6)]-O-beta-D-glucopyranosyl ester (2), 3-O-alpha-L-arabinofuranosyl-gypsogenic acid 28-O-beta-D-glucopyranosyl-(1 -> 3)-O-[beta-D-glucopyranosyl-(1 -> 2)-O-beta-D-glucopyranosyl-(1 -> 6)-O-]-beta-D-glucopyranosyl ester (3), 3-O-alpha-L-arabinofuranosyl-16 alpha-hydroxyolean-12-en-23,28-dioic acid-28-O-beta-D-glucopyranosyl-(1 -> 3)-O-[beta-D-glucopyranosyl-(1 -> 2)-O-beta-D-glucopyranosyl-(1 -> 6)]-O-beta-D-glucopyranosyl ester (4). Their structures were established by a combination of one-and two-dimensional NMR techniques, and mass spectrometry. Noteworthy, none of isolated compounds possesses as aglycone moiety gypsogenin, considered a marker of Caryophyllaceae family. The cytotoxic activity of the isolated compounds was evaluated against three cancer cell lines including A549 (human lung adenocarcinoma), A375 (human melanoma) and DeFew (human B lymphoma) cells. Only compound 6 showed a weak activity against A375 and DeFew cell lines with IC50 values of 77 and 52 mu M, respectively. None of the other tested compounds, in a range of concentrations between 12.5 and 100 mu M, caused a significant reduction of the cell number. (C) 2015 Phytochemical Society of Europe.
