    Ampelographic and Molecular Diversity among Grapevine (Vitis spp.) Cultivars
    (CZECH ACADEMY AGRICULTURAL SCIENCES, 2009) Sabir, Ali; Tangolar, Semih; Buyukalaca, Saadet; Kafkas, Salih
    This study Presents the ampelographic and molecular characterization of 44 grapevine cultivars. Ampelographic data were obtained during two vegetation periods using the latest version of the descriptors. Based on the mean values transformed by the method indicated in IBPGR publications, a dendrogram was constructed. ISSR analysis was also employed to characterize the genotypes at the DNA level. Twenty primers, selected on the basis of their discriminating potential, generated a total of 157 bands, of which 140 were polymorphic. The dendrograms constructed by the two approaches were largely similar in both the Clustering position and diver-gence of varietal groups. The least distance was observed between Yuvarlak Cokirdeksiz and Superior Seedless. The clustering position of cultivars throughout the dendrograms was basically related to the genetic distances and main uses, as well as to geographic origins.

    Cryptomarasmius corbariensis (Physalacriaceae, Agaricales) in Turkey with first molecular data on the species from Eurasia
    (GEBRUDER BORNTRAEGER, 2018) Bozok, Fuat; Taskin, Hatira; Buyukalaca, Saadet; Dogan, Hasan Huseyin; Assyov, Boris
    Cryptomarasmius corbariensis (Roum.) T.S.Jenkinson & Desjardin, a species confined primarily to litter of olive trees, is recorded for the first time from Asia and Turkey, based on identification by ITS sequences and morphological characters. Description and illustrations are included. An overview of the distribution is provided and briefly discussed with emphasis on the possibly wider extent than currently known.

    Four new morel (Morchella) species in the elata subclade (M. sect. Distantes) from Turkey
    (MYCOTAXON LTD, 2016) Taskin, Hatira; Dogan, Hasan Huseyin; Buyukalaca, Saadet; Clowez, Philippe; Moreau, Pierre-Arthur; O'Donnell, Kerry
    Four Turkish Morchella species identified in published multilocus molecular phylogenetic analyses are described here as new, using detailed macro-and microscopic data: M. mediterraneensis (Mel-27), M. fekeensis (Mel-28), M. magnispora (Mel-29), and M. conifericola (Mel-32). A distribution map of morels identified to date in Turkey is also provided.

    Morchella galilaea, an autumn species from Turkey
    (MYCOTAXON LTD, 2015) Taskin, Hatira; Dogan, Hasan Huseyin; Buyukalaca, Saadet
    Morchella specimens collected during the autumn seasons of 2009-12 from Adana Province, Turkey, have been identified by DNA sequencing as representatives of Morchella galilaea. The macro- and micromorphology, phylogeny, ecology, and fruiting phenology of the Turkish material are evaluated.

    Multiple Antioxidant and Bioherbicidal Assays of the Edible Mushroom Species "Ramaria flava" in the Amanos Mountains
    (BIOINTERFACE RESEARCH APPLIED CHEMISTRY, 2016) Bozdogan, Adnan; Eker, Tulin; Bozok, Fuat; Ulukanli, Zeynep; Dogan, Hasan Huseyin; Buyukalaca, Saadet
    The phenolic content (TPC) and flavonoids (TFC) of the methanol (MeOH) extract of the edible mushroom species 'Ramaria flava' in the native flora of Amanos Mountains were 89.0 and 0.97 mg/kg, respectively. beta-carotene content (TCC) (0.47 mg 100/mL) was higher than that of the lycopene (TLC) (0.19 mg/100 mL). Two-fold dilutions ranging from 1.25 to 5.0 mg/mL of the extract were used for antioxidant assays. The most significant activities were 94.17% for DPPH (2-diphenyl-1-picrylhydrazyl), 64.25% for NO (nitric oxide) scavenging, 2.43 Abs for reducing power (RP) and 1.94 Fe+2 mmol/L for Ferric-reducing antioxidant power (FRAP) assays at the upper concentration, respectively. The most prominent result for hydrogen peroxide (H2O2) scavenging assay at the following concentrations; 0.0156 to 0.125 mg/mL was 71.68% at 0.125 mg/mL. In the bioherbicidal assay, MeOH extract at 25 mg/mL inhibited the germination (16%), radicle growth (44%), plumule growth (52%), total chlorophyll a and b (78 and 88%), and carotenoid (70%) of Cucumis sativus. To conclude, FRAP, NO, and H2O2 scavenging activities of the MeOH extract of R. flava is the first report.

    Volatile Constituents of The Edible Tricholoma terreum in Marmara Region of Turkey
    (TAYLOR & FRANCIS LTD, 2017) Bozok, Fuat; Dogan, Hasan Hseyin; Taskin, Hatira; Kafkas, Ebru; Buyukalaca, Saadet
    Tricholoma terreum is a fungal species which is also commonly consumed and widespread in Turkey. Seventeen aroma compounds were identified with Headspace Solid-Phase Microextraction/Gas Chromatography/Mass Spectrometry (HS-SPME/GC-MS). Major aroma compounds in T. terreum were as follows; 1-octen-3-ol (37.08 %), (E)-2-octen-1-ol (19.68 %), hexanal (16.00 %), 3-octanone (3.36 %), acetic acid (2.63 %) and (E)-2-octenal (2.27 %). This study is the first report on the volatile aroma compounds of T. terreum in Turkey.
