Öğe 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, BorisCryptomarasmius 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.Öğe Determination of multiple antioxidant activities of endemic tricholoma anatolicum(2018) Taşkın, Hatıra; Eker, Tülin; Bozok, Fuat; Doğan, Hasan Hüseyin; Büyükalaca, SaadetTricholoma anatolicum H.H. Doğan & Intini is known as the most prized mushroomspecies in Feke region of Turkey. This mushroom species is collected from Cedar(Cedrus libani) forests and therefore is named as Cedar mushroom in this region. It iscollected and consumed by local collectors and also exported to Far East countries suchas Japan by exporting companies. Therefore, it is important to investigate the nutritionaland medical importance of this species. The aim of this study is to reveal the antioxidantactivity of methanol extract in different concentrations (1, 2 and 4 mg/mL) of T.anatolicum H.H. Doğan & Intini collected from Feke district of Adana province ofTurkey in 2015. In this study, it was determined that total phenolic content of thismushroom was 56 mg/kg. 2,2-diphenyl-1-picrylhydrazyl (DPPH), nitric oxide (NO) andreducing power (RP) activities given in trolox (?M) and ferric-reducing antioxidantpower (FRAP) given in FeSO4 (?M) were found as 449, 180, 337 and 2 at the highestconcentration (4 mg/mL), respectively. As a result, it could be suggested that methanolextract of T. anatolicum H.H. Doğan & Intini has significantly antioxidant activity.Öğe Investigation of antioxidant potential and phytotoxic effects of ganoderma lucidum methanol extract(2016) Bozok, Fuat; Eker, Tülin; Sezer, Gökhan; Bozdoğan, Adnan; Doğan, Hasan Hüseyin; Büyükalaca, SaadetThe aim of this study is to reveal allelopathic effects and antioxidant activities of methanolic extract of Ganoderma lucidum in Zorkun plateau (Osmaniye). It was determined that methanolic extract of G. lucidum has significantly phytotoxic effect by increasing the doses (1, 2, 4, 8 mg/mL) on Hordeum vulgare and Triticum aestivum. Total phenol and flavonoid amounts of G. lucidum were 114.55 mg/kg and 8.95 mg/kg, respectively. 2,2-diphenyl-1-picrylhydrazyl (DPPH), scavenging activity (60%, 91% and 92%), reducing power (0.83, 1.43 and 2.23 Abs), and nitric oxide (NO) scavenging activity (48%, 55% and 70%) of this mushroom at the different concentrations (1.25, 2.5 and 5 mg/mL) were determined, respectively. However, H2O2 scavenging activity of the different concentrations (0.0156-0.125 mg/mL) was found as 18%, 56%, 60% and 86%, respectively. Based on these findings, it can suggest that G. lucidum methanolic extract has significantly phytotoxic effect and antioxidant activity. The present study is the first report on the phytotoxic effects and antioxidant activities of G. lucidum which consumed and collected from Amanos Mountains.Öğe Moleküler Yöntemlerin Kullanımı İle Türkiye Morchella (Kuzugöbeği) Genetik Çeşitliliğine Katkılar(Selçuk Üniversitesi, Mantarcılık Uygulama ve Araştırma Merkezi Müdürlüğü, 2020) Bozok, Fuat; Keskinkılıç, İsmail; Akata, Ilgaz; Yarar, Mahmut; Taşkın, HatıraMorchella genus called as “kuzugöbeği” in Turkey, is consumed extensively in many countries including Turkey and it always maintains its scientific interest. Systematic studies on the genus Morchella have continued, new species have also been identified and synonyms have been determined. In this study, phylogenetic and morphological assessment of a collection consisting 50 samples collected from different locations of Turkey were performed. In phylogenetic analysis, internal transcribed spacer (ITS rDNA) and 28S rDNA (LSU) gene regions were used. At the end of the study, Morchella dunensis, M. tridentina, M. importuna, M. eximia, M. dunalii, M. mediterraneensis and M. deliciosa have been identified based on these gene regions.Öğe 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, SaadetThe 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.Öğe A New Macrofungi Record for Turkey and Asia with Molecular Characterization: Xerocomellus redeuilhii (Boletales, Basidiomycota)(Selçuk Üniversitesi, Mantarcılık Uygulama ve Araştırma Merkezi Müdürlüğü, 2019) Bozok, Fuat; Assyov, Boris; Taşkın, Hatıra; Büyükalaca, SaadetXerocomellus redeuilhii A.F.S.

Sm. & Thiers) was reported for the first time from Turkey. This species is characterized by its ectomycorrhizal features and the occurrence under Pseudotsuga menziesii (Douglas fir). Besides conventional identification methods, molecular methods (ITS rDNA) were also used and results were uploaded to GenBank. According to the Genbank results, our species shows 99% similarity to other data related to Suillus lakei. A short description with molecular analysis were given in the text and the results discussed briefly.Öğe Türkiye İçin Beş Yeni Morchella Kaydı(2016) Doğan, Hasan Hüseyin; Bozok, Fuat; Taşkın, Hatıra; Büyükalaca, SaadetÜlkemizde kuzu göbeği mantarı olarak bilinen Morchella türleri tüm dünyada sevilerek tüketilenmantarlardan arasında yer alır. Ticari değerinin yüksek olması nedeniyle, ülkemizin değişikbölgelerinden toplanarak, farklı ülkelere yaş ve kuru olarak ihracatı yapılmaktadır. Türkiye coğrafikkonumu ve çok eski yıllardan beri birçok medeniyete ev sahipliği yapması nedeniyle zengin birekolojik çeşitliliğe sahiptir. Bu ekolojik çeşitliliğin içerisinde mantarlarda önemli bir yerkaplamaktadır. Gen kaynaklarımızın korunması, öncelikli çalışma konularından olmalıdır ve buamaca ulaşabilmek için de öncelikle mevcut çeşitliliğimizin tanımlanması gerekmektedir. Sunulançalışmada, Türkiye'nin farklı bölgelerinden 2007-2010 yılları arasında toplanan örneklerin türtanımları yapılmıştır. Arazide GPS koordinatları alınarak fotoğrafları çekilen örnekler, laboratuvaragetirilmiş, mikroskobik ve morfolojik tanılamaları yapılmıştır. Daha sonra kurutulan örneklerde,DNA dizi analizleri gerçekleştirilmiştir. Çalışmada, Türkiye için 5 yeni Morchella kaydı: Morchellafluvialis Clowez, P. Alvarado, M. Becerra, Bilbao & P.A.
