(C M B Assoc, 2018) Fidan, Mehmet; Erez, Mehmet Emre; Inal, Behcet; Pinar, Suleyman Mesut; Altintas, Serdar
The quality of grape cultivars not only depends on the grape cultrvar 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 imestigated 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 Gad?v 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.

Fungi 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.

(Springer, 2019) Erez, Mehmet Emre; Dalar, Abdullah; Fidan, Mehmet; Pinar, Suleyman Mesut
This study presents the first comprehensive evaluation of antioxidant potential and phytochemical profiling of nine plant taxa utilized in southeastern and eastern parts of Turkey for various medicinal purposes, in order to contribute the scientific database, which was focused on exploring novel candidates of antioxidant agents from natural sources for industry and complementary medicine. 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.

An Expert Classification System of Pollen of Onopordum Using a Rough Set Approach
(Elsevier, 2013) Kaya, Yilmaz; Pinar, S. Mesut; Erez, M. Emre; Fidan, Mehmet
Although pollen grains have a complicated 3-dimensional structure, they can be distinguished from one 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, colpus weight, exine, intine, tectum, nexine, columellea, and echinae length) were measured 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.

(Taylor & Francis inc, 2014) Kaya, Yilmaz; Pinar, S. Mesut; Erez, M. Emre; Fidan, Mehmet; Riding, 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.

Seed Micromorphology and Anatomy of 36 Muscari (Asparagaceae) Taxa From Turkey With Notes on Their Systematic Importance
(Univ Zagreb, Fac Science, Div Biology, 2021) Eroglu, Huseyin; Karaismailoglu, Mehmet Cengiz; Pinar, Suleyman Mesut; Fidan, Mehmet
- This study presents the first in-depth evaluation of the morphological and anatomical characters, as well as their taxonomic importance, of the seeds of 36 taxa in subgenera Muscari, Leopoldia, Pseudomuscari and Botryanthus of the genus Muscari in Turkey, where 24 of the taxa are endemic. The results indicate that the taxa generally differ from each other in terms of seed shape and dimension. Seed dimensions vary between 1.66 mm and 3.21 mm in length, and between 1.12 mm and 2.63 mm in width. The seed surface ornamentation is grouped into nine forms: ru- minate, reticulate, reticulate-areolate, reticulate-foveate, alveolate, scalariform, rugose, verrucate and areolate. The most common type is ruminate, while areolate, reticulate-foveate and scalariform ornamentation forms were found to be taxon-specific. Testa structures of the taxa examined consist in general of two different layers: the epidermis and the subepidermis in scleranchymatous or parenchymatous structures. The subepidermis may be absent in some of taxa. The structure and thickness of the epidermis and the subepidermis are very important characteristics that dis- close interspecific relations among the examined taxa. We also provide a key for the identification of the studied taxa based on seed features.
