Scald (caused by Rhynchosporium secalis) is one of the major plant diseases of barley (Hordeum vulgare L.) cultivation in central Anatolia and transitional zones of Turkey. Eighty barley germplasm consisting of 40 resistant and 40 sensitive lines provided by Central Research Institute of Field Crops were screened with six simple sequence repeat (SSR) markers to assess the magnitude and pattern of genetic diversity, as well as to investigate potential use of these markers for efficient scald resistant breeding program in the future. Estimated genetic parameters indicated that scald resistant (He=0.43) and sensitive (He=0.40) barley lines still maintain large and similar magnitude of genetic diversity. However, genetic variation among the lines was higher in the sensitive lines (46%) than in the resistant lines (39%). Especially, the presence of high genetic diversity among resistant lines (e.g., R25, R39) suggests that this diversity could be an important drive in future scald resistant barley breeding programs. The results of this study also revealed that Bmag6 and Bmag206 as SSR markers could be utilized in pre-screening of large number of barley lines for future scald resistance breeding programs with reduced time, cost and labor

Genetic diversity of scald (rhynchosporium secalis) disease resistant and sensitive Turkish barley seed sources as determined with simple sequence repeats Dizkırıcı, Ayten; Kaya, Zeki; Department of Biology (2006) Scald disease (Rhynchosporium secalis) is one of the major plant diseases causing considerable yield loss in barley (Hordeum vulgare) plantations in Turkey. To develop, scald resistant barley varieties, C.R.I.F.C. of Turkey has a large accumulated collection of barley seed sources in hand, but these samples are difficult to be followed and used in the breeding programs due to lack of genetic studies on them. Thus, the objective of this study was to characterize and fingerprint of eighty barley seed sources,...
Functional analysis of a mirna putatively involved in powdery mildew disease susceptibility in barley Dağdaş, Gülay; Akkaya, Mahinur S.; Department of Biotechnology (2009) Barley is one of the most important crop species in Turkey and powdery mildew is one of the most common pathogen decreasing yield in barley. For this problem, agricultural biologists apply breeding technologies in order to select and propagate resistant barley cultivars. However, this is not a permanent solution since pathogens evolve rapidly to overcome plant resistance mechanisms. On the other hand, molecular plant pathologists are trying to understand basic mechanisms underlying plant-pathogen interactio...
Genetic differentiation between clone collections and natural populations of European black poplar (Populus nigra L.) in turkey Çiftçi, Asiye; Kucukosmanoglu, Filiz; Karahan, Alptekin; Kaya, Zeki (2017-06-01) The European black poplar (Populus nigra L.) is an ecologically and economically important tree species for Turkey. The important and major genetic resources of species for future breeding and ex situ conservation purposes have been archived in a clone bank in Ankara by selecting clones from natural populations and old plantations throughout Turkey. There is no study to date assessing genetic composition these materials. Two-hundred-thirty-three P. nigra clones from six geographic region of Turkey (clone co...
Antioxidant capacities of Gundelia tournefortii L. extracts and inhibition on glutathione-S-transferase activity Çoruh, Nursen; Ozgokce, F.; Iscan, M. (Elsevier BV, 2007-01-01) Gundelia tournefortii L. is an important food source and a well-known medicinal plant in Eastern Anatolia. Therapeutic effects of medicinal plants are known to be closely related to their antioxidant capacities. Antioxidant activities of G. tournefortii, both for the aerial parts and seeds, were investigated by using both 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and lipid peroxidation inhibition methods. The seeds were found to have higher antioxidant potential than the aerial, with IC50 valu...
Microarray based expression profiling of barley under boron stress and cloning of 3H boron tolerance gene Öz, Mehmet Tufan; Eyidoğan, Füsun; Öktem, Hüseyin Avni; Department of Biotechnology (2012) Both deficiency and toxicity of the essential micronutrient boron (B) lead to reduced crop yield in agriculture. However, our understanding of the molecular responses of plants under B stresses to tackle the yield loss is limited. Therefore, in the present study, transcriptional alterations in sensitive and tolerant barley cultivars under B deficiency and toxicity were investigated in order to reveal the molecular responses. Transcriptomes were monitored at seedling stage by global expression profiling usin...
