18S rDNA AND beta-TUBULIN DIVERSITY IN RHIZOCTONIA ZEAE VOORHEES
Gurkanli, Cem Tolga; Aydin, Emine Banu; Demirci, Erkol; Erper, Ismail; Karaca, Gursel; Hsieh, Ting-Fang; Ozkoc, Ibrahim (Pakistan Botanical Soc, 2016)Waitea circinata Warcup & Talbot, which is related to the anamorphic form-genus Rhizoctonia D.C., is a world wide distributed soil-borne fungal pathogen. Several molecular based studies have been published based on rDNA-ITS ... -
Assessing 18S rDNA Diversity of the Chlorophytes among Various Freshwaters of the Central Black Sea Region
Baytut, Ozgur; Gurkanli, Cem Tolga; Ozkoc, Ibrahim; Gonulol, Arif (Central Fisheries Research Inst, 2013)In this study, diversity of unicellular chlorophytes isolated from various freshwater habitats in the Central Black Sea Region were assessed by the molecular phylogenetic methods. In order to determine diversity, water ... -
First molecular records of potentially harmful planktonic dinoflagellates from the southern Black Sea
Baytut, Ozgur; Gurkanli, Cem Tolga; Deniz, Eda; Ozkoc, Ibrahim; Gonulol, Arif (Tubitak Scientific & Technical Research Council Turkey, 2016)The aim of this study was to identify dinoflagellate species from the Black Sea (Samsun coast) using conventional and molecular phylogenetic methods. Water samples were collected using a plankton net with 22 mu m pores. ... -
First Report of B.N. Rhizoctonia From Tobacco (Nicotiana Tabacum L.) in Samsun, Turkey
Gurkanli, Cem Tolga; Ozkoc, Ibrahim (Pakistan Botanical Soc, 2011)In this study, 14 fungal samples were isolated from tobacco (Nicotiana tabacum L.) cultivated in Samsun-Turkey, corresponded with binucleate Rhizoctonia (BNR) anamorphic criteria. Of these, 10 isolates were identified as ... -
Genetic diversity of Amsonia orientalis
Gurkanli, Cem Tolga; Ozkoc, Ibrahim; Aydin, Emine Banu; Acemi, Arda; Ozen, Fazil (Springer, 2014)Amsonia orientalis Decne. (Apocynaceae), is a rare and threatened plant species which is located only in a constricted area in northeast of Greece and northwest of Turkey in the world. Although phylogenetic analysis depending ... -
Genetic diversity of rhizobia nodulating common bean (Phaseolus vulgaris L.) in the Central Black Sea Region of Turkey
Gurkanli, Cem Tolga; Ozkoc, Ibrahim; Gunduz, Islam (Springer, 2013)We have analyzed 30 rhizobial isolates obtained from common bean (Phaseolus vulgaris L.) root nodules grown in the Middle Blacksea Region of Turkey, using ARDRA and nucleotide sequence data. ARDRA analysis with enzymes ... -
Genetic diversity of Vicia faba L. and Pisum sativum L. nodulating rhizobia in the central Black Sea region of Turkey
Gurkanli, Cem Tolga; Ozkoc, Ibrahim; Gunduz, Islam (Springer, 2014)In this study, we obtained a total of 60 rhizobial isolates from root nodules of Vicia faba L. (n = 30) and Pisum sativum L. (n = 30) grown in the Central Black Sea region of Turkey. The 16S rDNA PCR-RFLP analysis with ... -
Molecular and Conventional Identification and Pathogenicity of Rhizoctonia solani Isolates from Tobacco (Nicotiana tabacum L.) in Samsun, Turkey
Gurkanli, Cem Tolga; Ozkoc, Ibrahim; Gunduz, Islam (Wiley, 2009)A total of 101 fungal samples were isolated from tobacco (Nicotiana tabacum L.) plants in Samsun, Turkey and identified as Rhizoctonia solani. Of these samples, three were identified as belonging to Anastomosis Group (AG) ... -
Molecular characterization of Rhizoctonia solani AG4 using PCR-RFLP of the rDNA-ITS region
Kilicoglu, Melike Cebi; Ozkoc, Ibrahim (Tubitak Scientific & Technical Research Council Turkey, 2010)Rhizoctonia solani isolates obtained from common beans (Phaseolus vulgaris L.) were included in an AG4 anastomosis group in accordance with hyphal anastomosis. In the subgrouping of AG4 isolates, PCR-RFLP patterns in the ... -
Molecular phylogeny of Chlorella-related chlorophytes (Chlorophyta) from Anatolian freshwaters of Turkey
Baytut, Ozgur; Gurkanli, Cem Tolga; Gonulol, Arif; Ozkoc, Ibrahim (Tubitak Scientific & Technical Research Council Turkey, 2014)This study aimed to investigate molecular taxonomic diversity of unicellular chlorophyte strains in the northern Anatolian freshwater habitats of Turkey. Five strains were isolated from various habitats i.e. salty lagoons, ... -
Phylogenetic analysis of Rhizoctonia solani AG-4 isolates from common beans in Black Sea coastal region, Turkey, based on ITS-5.8S rDNA
Kilicoglu, Melike Cebi; Ozkoc, Ibrahim (Tubitak Scientific & Technical Research Council Turkey, 2013)In this study, 114 Rhizoctonia solani isolates were obtained from diseased common bean (Phaseolus vulgaris L.) plants from the Black Sea coastal region of Turkey. Genetic variation was determined among R. solani anastomosis ... -
The viability of Anacamptis laxiflora (Orchidaceae) seeds and the symbiotic germination
Kompe, Yasemin Ozdener; Mutlu, Vildan Akin; Ozkoc, Ibrahim (Taylor & Francis Ltd, 9999)The orchids are in danger of extinction due to the destruction of their habitats and uncontrolled collection. The most effective way of protecting plants' gene resources against these gradually increasing threats is seed ...
