Öğe Genome-wide fungal stress responsive miRNA expression in wheat(Springer, 2014) Inal, Behcet; Turktas, Mine; Eren, Hakan; Ilhan, Emre; Okay, Sezer; Atak, Mehmet; Erayman, MustafaMicroRNAs (miRNAs) are small non-coding class of RNAs. They were identified in many plants with their diverse regulatory roles in several cellular and metabolic processes. A number of miRNAs were involved in biotic and abiotic stress responses. Here, fungal stress responsive wheat miRNAs were analyzed by using miRNA-microarray strategy. Two different fungi (Fusarium culmorum and Bipolaris sorokiniana) were inoculated on resistant and sensitive wheat cultivars. A total of 87 differentially regulated miRNAs were detected in the 8 x 15 K array including all of the available plant miRNAs. Using bioinformatics tools, the target transcripts of responsive miRNAs were predicted, and related biological processes and mechanisms were assessed. A number of the miRNAs such as miR2592s, miR869.1, miR169b were highly differentially regulated showing more than 200-fold change upon fungal-inoculation. Some of the miRNAs were identified as fungal-inoculation responsive for the first time. The analyses showed that some of the differentially regulated miRNAs targeted resistance-related genes such as LRR, glucuronosyl transferase, peroxidase and Pto kinase. The comparison of the two miRNA-microarray analyses indicated that fungal-responsive wheat miRNAs were differentially regulated in pathogen- and cultivar-specific manners.Öğe Genome-wide identification of salinity responsive HSP70s in common bean(Springer, 2016) Buyuk, Ilker; Inal, Behcet; Ilhan, Emre; Tanriseven, Mehmet; Aras, Sumer; Erayman, MustafaThe present study is aimed to identify and characterize HSP70 (PvHSP70) genes in two different common bean cultivars under salt stress. For this purpose various in silico methods such as RNAseq data and qRT-PCR analysis were used. A total of 24 candidate PvHSP70 gene were identified. Except for chromosome 4 and 7, these candidate PvHSP70 genes were distributed on the remaining chromosomes. While the lowest number of PvHSP70 genes was determined on chromosomes 1, 3, 5, 7, 9, 10 and 11 (one HSP70 gene), the highest number of PvHSP70s was on chromosomes 6 and 8 (seven HSP70 genes each). Three genes; PvHSP70-5, -9, and -10 were found to have no-introns. In addition, four tandemly and six segmentally duplicated gene couples were detected. A total of 13 PvHSP70 genes were targeted by miRNAs of 44 plant species and the most targeted genes were PvHSP70-5 and -23. The expression profile of PvHSP70 genes based on publicly available RNA-seq data was identified and salt treated leaf tissue was found to have more gene expression levels compared to the root. qRT-PCR analysis showed that the transcript concentrations of upregulated PvHSP70 genes in leaves of Zulbiye (sensitive) were mostly higher than those of Yakutiye (resistant). The present study revealed that PvHSP70 genes might play an important role in salt stress response for common bean cultivars and variability between cultivars also suggests that these genes could be used as functional markers for salt tolerance in common bean.Öğe IDENTIFICATION OF SSR AND EST MARKERS ASSOCIATED WITH WATERLOGGING TOLERANCE IN BREAD WHEAT(Parlar Scientific Publications (P S P), 2015) Atak, Mehmet; Ilhan, Emre; Erayman, Mustafa; Dilbirligi, Muharrem; Eren, Abdil Hakan; Arslan, Mehmet; Celiktas, NafizCrop production is significantly limited by waterlogging especially in high rainfall and poorly drained regions in the world. Hence, breeding for waterlogging tolerance to increase production is one of the main objectives of breeders. Similar to other abiotic stress tolerances, the tolerance to waterlogging is a complex trait and difficult to select for in breeding programs. Marker assisted selection has been an effective method for crop improvement by utilizing markers closely related to target traits combined with accurate phenotyping of key factors. In the present study, two bread wheat (Triticum aestivum L.) F-2:3 populations ('Dogankent' x 'Ducula-4' and 'Ducula-1' x 'Seri-82') derived from susceptible cultivars ('Dogankent' and 'Seri-82') and tolerant ('Ducula-1' and 'Ducula-4') lines were treated with four weeks of waterlogging and screened in two different locations. Additionally, 32 expressed sequence tags and 210 microsatellite markers were screened for analysis of marker trait associations; of which less than %20 (45) of those markers were polymorphic between parents of both populations. Tolerance, yield and quality related traits including plant height index, tillering index, adventitious root formation, heading date, tolerance scoring index, total kernel number and thousand kernel weight were identified to be mostly affected by environment. Marker - trait analyses identified markers significantly associated with waterlogging tolerance as well as yield and quality component traits. In the 'Dogankent' x `Ducula-4' derived population, two markers explaining more than 10% of the total variance for adventitious root formation and thousand kernel weight were detected both on chromosomes 3DL (Xgwm645) and 4AL (Xgwm160). This is one of the first studies revealing markers linked to the tolerance related traits in spring wheat under waterlogging conditions.Öğe Identification of SSR and EST markers associated with waterlogging tolerance in bread wheat(Parlar Scientific Publications, 2015) Atak, Mehmet; Ilhan, Emre; Erayman, Mustafa; Dilbirli?i, Muharrem; Eren, Abdil Hakan; Arslan, Mehmet; Çeliktas, NafizCrop production is significantly limited by waterlogging especially in high rainfall and poorly drained regions in the world.

The material including total genomic DNA was extracted by the CTAB, and for PCR reaction, a total of 14 SSR primers developed for Medicago truncatula were used. PCR amplifications were performed in a Multigen(A (R)) Thermal Cycler. Soil samples were analysed for their texture, pH, total soluble salts, calcium carbonate, total N content, total phosphorus and organic matter content. In order to see the association between genetic, ecological and geographical data, a similarity matrix was generated. Genetic similarity distances between genotypes were correlated with those of Eucledian distances obtained from ecological and geographical data. Analysis of molecular variance (AMOVA) was performed using GenAlEx 6.5 software to determine variation among and within genetic variations. The genetic analysis showed that the highest expected heterozygosity values were obtained from G. glabra while the lowest were obtained from G. echinata. In general heterozygosity values were low, especially for G. echinata. Therefore, variation appears to be lower within each species than among three species. The physical and chemical analysis of soil and plant samples indicates that mineral accumulation in plants is substantially affected by the soil characteristics. There is a need for identification of better strategies for the improvement of varieties, especially for small farmers managing marginal soils. More studies should be conducted in order to safeguard these taxa, especially G. glabra var. glandulifera which is collected intensively due to its economic value, the same is true for endemic taxon G. flavescens ssp. flavescens.Öğe NUCLEAR DNA CONTENT VARIATION AMONG GLYCYRRHIZA TAXONS COLLECTED FROM EAST MEDITERRANEAN(Parlar Scientific Publications (P S P), 2017) Ilhan, Emre; Ozgur, Sevda; Tuna, Gulsemin Savas; Eren, Abdil Hakan; Karahan, Faruk; Tuna, Metin; Erayman, MustafaIn this study, we performed nuclear DNA content determination of three different licorice species (G. flavescens Boiss, G. glabra L. var. glandulifera and G. echinata L.) collected from three different geographical regions of Hatay Province (Arsuz, Kirikhan, and Antakya) in the East Mediterranean Region. Previous cytogenetic studies in Glycyrrhiza genus is limited to chromosome counts by classical methods and no information was available on nuclear DNA content of the species included within the genus. Nuclear DNA content information is constant among individuals of one species, therefore, it is species specific. This makes nuclear DNA content information very useful for taxonomic, evolutionary, and genetic studies. Nuclear DNA content information (pg) can be converted to genome size (bp) by using a simple equation and it is critical for genome sequencing projects. In this study, nuclear DNA content of three different Glycyrrhiza species were comparatively analyzed for the first time by using flow cytometry method. Based on the results of the study G. flavesences (1.138 0,013 pg, 1112.96 Mbp) had larger nuclear DNA content than those of G. glabra (0.967 0,009, 945.73 Mbp) and G. echinata (0.946 0,008 pg, 925.19 Mbp). These results indicate that G. flavescens have different genomes than G. glabra and G. echinata, which have more similar genomes. The results of this study will be useful for taxonomic identification of Glycyrrhiza species and to understand their geno-mic structures and relations.Öğe Phylogenetic relationship among taxa in the genus Adonis L. collected from Turkiye based on nrDNA internal transcribed spacer (ITS) markers(Springer, 2022) Karahan, Faruk; Ilcim, Ahmet; Turkoglu, Aras; Ilhan, Emre; Haliloglu, KamilBackground Genus Adonis L. contain approximately 40 annual and perennial species, which are widely distributed in the temperate zones of Asia and Europe, and less frequently in southwestern Asia, northern Africa and the Mediterranean region. The aim of the study was to evaluate the phylogenetic relationship among Adonis taxa collected from Turkiye based on nrDNA Internal transcribed spacer (ITS) markers. Methods Samples of 64 individual genotypes from 21 populations of 10 Adonis taxa were collected from different regions of the country during vegetation period between 2014 and 2018. ITS1, ITS4, P16 and P25 primers within ITS technique was used to genotype the plant materials. Then, genotypic data was used to estimate magnitude and organization of infraspecific variation in different populations of Adonis. Results About 600 bp DNA sequences were obtained from each 64 Adonis genotypes belonging to 21 different populations. The dendrogram obtained from Adonis taxa and out-group sequences had two large main groups. While the out-group species were placed in the first large main group, the sect. Consiligo (perennial) and sect. Adonis (annuals) were placed in different sub-groups of the second large main group. Genetic similarity among Adonis taxa varied between A. microcarpa and A. dentata (98.46%). Principal component analysis indicated that two important components in Adonis taxa genotypes. The expected heterozygosity ranged from 0.0252 (sub-population A) to 0.3460 (sub-population C), with an average of 0.1154. In addition, population differentiation measurements (Fst) ranged from 0.0025 (sub-population C) to 0.9016 (sub-population A) with a relatively high average 0.6601. Conclusions Present analyses revealed that phylogenetic classification (grouping) of Adonis taxa largely depended on morphological structure and present ITS primers were quite efficient in putting forth the genetic diversity of such species. The results of this study suggested that ITS markers could be used in the identification of genetic diversity among the Adonis taxa. The results obtained from molecular data can be used to explore the genetic variation pattern, population structure, and the evolutionary history of genus Adonis in the future.Öğe Physiological and gene expression differences of wheat varieties under different waterlogging treatments(Elsevier Sci Ltd, 2011) Erayman, Mustafa; Ergun, Nuray; Yilmaz, Ebru Sebnem; Ilhan, Emre; Ozcubukcu, Serhat; Eren, Abdil Hakan; Hancer, Tugce[Abstract Not Available]Öğe Screening wheat orthologs of tomato fw2.2 gene and their expression analysis(Elsevier Sci Ltd, 2011) Ilhan, Emre; Demirel, Ufuk; Eren, A. Hakan; Atak, Mehmet; Erayman, Mustafa[Abstract Not Available]Öğe Transcriptome analysis of wheat inoculated with Fusarium graminearum(Frontiers Media Sa, 2015) Erayman, Mustafa; Turktas, Mine; Akdogan, Guray; Gurkok, Tugba; Inal, Behcet; Ishakoglu, Emre; Ilhan, EmrePlants are frequently exposed to microorganisms like fungi, bacteria, and viruses that cause biotic stresses. Fusarium head blight (FHB) is an economically risky wheat disease, which occurs upon Fusarium graminearum (Fg) infection. Moderately susceptible (cv. Mizrak 98) and susceptible (cv. Gun 91) winter type bread wheat cultivars were subjected to transcriptional profiling after exposure to Fg infection. To examine the early response to the pathogen in wheat, we measured gene expression alterations in mock and pathogen inoculated root crown of moderately susceptible (MS) and susceptible cultivars at 12 hours after inoculation (hai) using 12X135K microarray chip. The transcriptome analyses revealed that out of 39,179 transcripts, 3668 genes in microarray were significantly regulated at least in one time comparison. The majority of differentially regulated transcripts were associated with disease response and the gene expression mechanism. When the cultivars were compared, a number of transcripts and expression alterations varied within the cultivars. Especially membrane related transcripts were detected as differentially expressed. Moreover, diverse transcription factors showed significant fold change values among the cultivars. This study presented new insights to understand the early response of selected cultivars to the Fg at 12 hai. Through the KEGG analysis, we observed that the most altered transcripts were associated with starch and sucrose metabolism and gluconeogenesis pathways.
