Öğe An automatic identification method for the comparison of plant and honey pollen based on GLCM texture features and artificial neural network(Taylor & Francis As, 2013) Kaya, Yilmaz; Erez, Mehmet Emre; Karabacak, Osman; Kayci, Lokman; Fidan, MehmetPollen grains vary in colour and shape and can be detected in honey used as a way of identifying nectar sources. Accurate differentiation between pollen grains record is hampered by the combination of poor taxonomic resolution in pollen identification and the high species diversity of many families. Pollen identification determines the origin and the quality of the honey product, but this indefiniteness is also a big challenge for the beekeepers. This study aimed to develop effective, accurate, rapid and non-destructive analysis methods for pollen classification in honey. Ten different pollen grains of plant species were used for the estimation. GLCM (grey level co-occurrence matrix) texture features and ANN (artificial neural network) were used for the identification of pollen grains in honey by the reference of plant species pollen. GLCM has been calculated in four different angles and offsets for the pollen of the plant and the honey samples. Each angle and offset pair includes five features. At the final step, features were classified using the ANN method; the success of estimation with ANN was 88.00%. These findings suggest that the texture parameters can be useful in identification of the pollen types in honey products.Öğe Antioxidant capacity and phylogenetic analysis of twenty native grape cultivars in Siirt province, Turkey(2018) Fidan, Mehmet; Erez, Mehmet Emre; İnal, Behçet; Pınar, Süleyman Mesut; Altıntaş, SerdarThe quality of grape cultivars not only depends on the grape cultivar but also is influenced by the molecular concepts and agro-climatic factors. For this purpose, four different grape cultivars were collected from five different locations in Siirt province (Turkey). Totally twenty different grape cultivars were investigated. In the present study, the antioxidant activity (total phenolic, flavonoid, proanthocyanidin content, DPPH and FRAP activity) in seeds were indicated and phylogenetic analysis (cpDNA;trnL-F region) of twenty native grape cultivars were investigated to construct their phylogenetic tree. According to reported data on antioxidant activity and content of phytochemicals, all cultivars exhibited different values from each other, but Rutik and Gadüv cultivars were found as significantly higher in comparison to others. According to bioinformatics analysis, twenty grape cultivars were distributed into six different major groups. Rutik and Sevkeye cultivars exhibit significant distinction from other grape cultivars. The phylogenetic analysis was also associated and supported with the results of obtained data from bioactivity. The bioactivity and phylogenetic analysis were firstly identified and quantified in these grape cultivars, however, with regard to obtained data from the current study, the grape cultivars grown in Siirt province were indicated significant and valuable results and as a result, these cultivars have to be evaluated before extinction.Öğe Antioxidant, antimicrobial, cytotoxic and protective effects of truffles(Academic Press Inc Elsevier Science, 2022) Fidan, Mehmet; Ali, Muhammad Muddassir; Erez, Mehmet Emre; Cigerci, Ibrahim Hakki; Ozdemir, Sadin; Sen, FatihFungi can be used as a potent chemotherapeutic agent to treat various cancers. In current study acetone and methanol extracts of Terfezia claveryi, Terfezia boudieri, Terfezia olbiensis, Picoa lefebvrei, Picoa juniperi were used to assess total phenolic contents, antioxidant activity, ion-chelating impact, antimicrobial activity, the cytotoxic and protective effects. Both methanol and acetone extracts of T. boudieri had the highest FRAP and DPPH scavenging abilities. Dose-dependent increased ion-chelating impact of all tested truffles species was found. Extracts of T. boudieri, T. claveryi, and T. albiensis exhibited higher antimicrobial activities. T. claveryi and T. boudieri showed the highest protective effects against H2O2-induced genotoxicity (P < 0.05), in S. cerevisiae BY4741. The least protective effect was showed by the acetone extracts of T. olbiensis (144 +/- 8); methanol ex-tracts of P. lefebvrei (140 +/- 8) and P. juniperi (140 +/- 10). MCF 7 cells showed more sensitivity against to methanol extracts of T. boudieri at 10-100 mu g/mL concentrations. HepG2 cells showed more sensitivity against the methanolic extracts of T. boudieri at both doses. Overall, P. lefebvrei and P. juniperi extracts had the least cytotoxic effects. The species of Terfezia exhibit significant protective effects against DNA damage and also have the potential of cytotoxicity effects.Öğe Characterization of Multifloral Honeys of Pervari Region with Different Properties(2015) Erez, Mehmet Emre; Karabacak, Osman; Kayci, Lokman; Fidan, Mehmet; Kaya, YılmazThe quality of honey from Pervari region was almost known by all over the country in Turkey.

Sequential extracts were prepared from plant materials were prepared through treating different solvents (acetone, ethanol, and water) based on polarity index. According to antioxidant assays via hydrogen atom transfer (HAT) and single atom transfer (SET) mechanisms, acetone extracts were found as the efficient antioxidant sources. Chromatographic studies revealed that phenolic compounds (mainly 5-O-Caffeoylquinic acid, luteolin hexoside, quercetin and rutin) were characterized as major hydrophilic phytochemical compounds and fatty acids (princibally linolenic, palmitic, and linoleic acids) were found as the major volatile compounds that dominantly contribute to the pronounced antioxidant capacities. According to the chemical structure, catechol moiety containing plant extracts had superior antioxidant capacity both for HAT and SET mechanisms. Data obtained from this study showed that among native botanicals, Crepis hakkarica, Crepis gemicii, Laserpitium carduchorum and Hedysarum vanaense might serve bioactive antioxidant agents both for industrial and pharmaceutical use.Öğe Determination of Biological Activity and Active Substances of Thecocarpus Carvifolius (BOISS.)

In fact, the content and component of bee products varies depending on many ecological and floristic factors and its nutritional and therapeutic properties are directly related to its content. Balveren (Şırnak province) beekeepers place their hives in locations with different geographical structure, floristic and topographic characteristics. This variability not only affects the quality of honey but also changes the properties of propolis. Studies on propolis, known as bee glue, have gained importance in recent years. As with other bee products, the propolis content also depends on the floristic characteristics of the region. In this study, propolis samples were collected from the regions where Balveren beekeepers stayed and their botanical origins, wax ratios, phenolic content, and mineral substance contents were analyzed. In the microscopic analysis, pollen grains belonging to 14 different families used by bees were determined. It was determined that the total phenolic and mineral contents of propolis vary completely depending on the location. With this study, the propolis properties of the hives in the region were tried to be revealed and it was aimed that this study would help the region's propolis to be used for technological and therapeutic purposes.Öğe Doğu ve Gu?neydoğu Anadolu’da Yayılış Gösteren Bazı Endemik Tu?rlerin Antioksidan Kapasitelerinin Belirlenmesi ve Etken Maddelerinin Tespit Edilmesi(2016) Erez, Mehmet Emre; Pınar, Süleyman Mesut; Dalar, Abdullah; Fidan, MehmetÜlkemiz, cografik konum ve jeolojik yapı bakımından, farklı topografik yapılara ve toprak gruplarına sahip, degisik iklim tiplerinin etkisi altında ve u?ç farklı bitki cografyası bölgesinin birlestigi yerde bulunmasınedeni ile zengin bir flora ile çok degisik vejetasyon tiplerine sahiptir.

This biotic stress resistance can provide advantage and increase productivity in agricultural systems. However, while there is extensive research on the pathways involved in abiotic stress tolerance, the impact on the molecular mechanisms underlying pathogen resistance remains poorly understood. Among the pathogens , Phytophthora capsici , an oomycete, causes severe damage as plant pathogen, leading to blight and fruit rot in pepper and other commercially valuable crops. This study investigates the effects of Phytophthora capsici infection on highly resistant (CM334) and susceptible (Sera Demre) pepper varieties. We examined biochemical changes and gene expression across different vegetative periods (seedling, flowering, and fruiting stages). Specifically, we analyzed biochemical pathways and the mitochondrial transcription termination factor (mTERF) gene regions associated with pathogenicity. In pepper seedlings infected with P. capsici , peroxide levels increased at all developmental stages compared to control groups. Additionally, we observed a rise in H 2 O 2 content, a molecule involved in signal transduction, likely due to the oxidative stress caused by the pathogen. The expression patterns of mTERF genes varied significantly depending on both pathogen application and the developmental stage of the plants. In the seedling stage, inoculation with P. capcici resulted in decreased expression of TERF2, mTERF6, and mTERF8 genes in leaf parts of both resistant and susceptible varieties. However, mTERF28 expression showed a significant increase. Interestingly, mTERF14 and mTERF27 gene expressions increased in the resistant variety but decreased in the susceptible one. These findings, although not providing a complete picture of host resistance mechanisms, highlight the crucial role of specific plant genes in the defense pathways against Phytophthora capsici . This knowledge can contribute to selecting pepper varieties with sustainable resistance to this devastating pathogen.Öğe An expert classification system of pollen of Onopordum using a rough set approach(2012) Kaya, Yılmaz; Pınar, Süleyman Mesut; Erez, Mehmet Emre; Fidan, MehmetAlthough pollen grains have a complicated 3-dimensional structure, they can be distinguished fromone another by their specific and distinctive characteristics. Using microscopic differences between the pollen grains, it may be possible to identify them by family or even at the genus level. However for the identification of pollen grains at the taxon level, we require expert computer systems. For this purpose, we used 20 different pollen types, obtained from the genus Onopordum L. (Asteraceae). For each pollen grain, 30 different images were photographed by microscope system and 11 different characteristic features (polar axis, equatorial axis, P/E ratio, colpus length, colpusweight, exine, intine, tectum, nexine, columellea, and echinae length)weremeasured for the analysis. The data set was formed from 600 samples, obtained from 20 different taxa, with 30 different images. The 440 samples were used for training and the remaining 160 samples were used for testing. The proposed method, a rough set-based expert system, has properly identified 145 of 160 pollen grains correctly. The success of the method for the identification of pollen grains was obtained at 90.625% (145/160). We can expect to achieve more efficient results with different genuses and families, considering the successful results in the same genus. Moreover, using computer-based systems in revision studies will lead us to more accurate and efficient results, and will identify which characters will be more effective for pollen identification. According to the literature, this is the first study for the identification and comparison of pollen of the same genus by using the measurements of distinctive characteristics with computer systems.Öğe Identification of Onopordum pollen using the extreme learning machine, a type of artificial neural network(2014) Kaya, Yılmaz; Pınar, Süleyman Mesut; Erez, Mehmet Emre; Fidan, Mehmet; Reading, James B.Pollen grains are complex three-dimensional structures, and are identified using specific distinctive morphological characteristics. An efficient automatic system for the accurate and rapid identification of pollen grains would significantly enhance the consistency, objectivity, speed and perhaps accuracy of pollen analysis. This study describes the development and testing of an expert system for the identification of pollen grains based on their respective morphologies. The extreme learning machine (ELM) is a type of artificial neural network, and has been used for automatic pollen identification. To test the equipment and the method, pollen grains from 10 species of Onopordum (a thistle genus) from Turkey were used. In total, 30 different images were acquired for each of the 10 species studied. The images were then used to measure 11 morphological parameters; these were the colpus length, the colpus width, the equatorial axis (E), the polar axis (P), the P/E ratio, the columellae length, the echinae length, and the thicknesses of the exine, intine, nexine and tectum. Pollen recognition was performed using the ELM for the 50–50%, 70–30% and 80–20% training-test partitions of the overall dataset. The classification accuracies of these three training-test partitions of were 84.67%, 91.11% and 95.00%, respectively. Therefore, the ELM exhibited a very high success rate for identifying the pollen types considered here. The use of computer-based systems for pollen recognition has great potential in all areas of palynology for the accurate and rapid accumulation of data.Öğe Morphological, anatomical, palynological and ecological data on the local endemic Dianthus vanensis (Caryophyllaceae) from Turkey(Phytotaxa, 2019-02) Karaismailoğlu, Mehmet Cengiz; Erez, Mehmet Emre; Pınar, Süleyman Mesut; Fidan, Mehmet; Eroğlu, HüseyinA first detailed taxonomical, palynological, and ecological study of the Turkish endemic Dianthus vanensis is shown based on field data collected at locus classicus.
