GREEN SYNTHESIS, CHARACTERIZATION AND ANTIMICROBIAL ACTIVITY OF SILVER NANOPARTICLES (AgNPs) FROM MAIZE (ZEA MAYS L.)
(APPLIED ECOLOGY AND ENVIRONMENTAL RESEARCH, 2019) Eren, Abdullah; Baran, Mehmet Fırat; Department of Medical Services and Techniques / Tıbbi Hizmetler ve Teknikleri Bölümü; Department of Organic Agriculture / Organik Tarım Bölümü
In recent years, the biosynthesis (green synthesis) of metal nanoparticles such as silver nanoparticles (AgNPs) have become one of the safest, most cost-effective and environmentally friendly approaches. In this study, AgNPs were synthesized using maize (Zea mays L.) leaves. For the characterization of synthesized AgNPs different techniques were used, such as X-ray diffraction spectroscopy (XRD), Ultraviolet visible (UV-Vis) spectroscopy, transmission electron microscopy (TEM), Energy dispersive X-ray spectroscopy (EDX), Fourier-transformed infrared spectroscopy (FT-IR) and Thermal gravimetric and Differential thermal analysis (TGA-DTA). The XRD results showed that AgNPs had a mean diameter of 12.63 nm and a crystal-like appearance. In addition, antimicrobial activities of synthesized AgNPs were evaluated using 3 different antibiotics against Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus bacteria and Candida albicans yeast. Antifungal activity of AgNPs with antibiotics has been observed to be better than the antibiotics against Gram-positive and Gram-negative bacteria. The minimum inhibitory concentrations were found to be 0.084, 0.337 and 0.021 mg mL-1 for Escherichia coli, Staphylococcus aureus, and Candida albicans, respectively. The results revealed that AgNPs synthesized from maize leaf extract have antibacterial activity against Gram-negative Escherichia coli, Gram-positive Staphylococcus aureus and antifungal activity against Candida albicans yeast, and that the produced AgNPs could be used in the production of biomedical products and in the pharmaceutical industry.
THE CADMIUM PHYTOEXTRACTION EFFICIENCY OF SCMTII GENE BEARING TRANSGENIC TOBACCO PLANT
(Biotechnology & Biotechnological Equipment, 2010) Eren, Abdullah; Arslan, Mehmet; Uygur, Veli; Köleli, Nurcan; Eren, abdullah; Department of Organic Agriculture / Organik Tarım Bölümü
Cadmium pollution is a serious world-wide problem affecting the human health and the environmental quality. Phytoremediation, the use of green plants to remove, sequester or detoxify pollutants offers an environmentally-friendly alternative to engineeringbased methods for remediation. The T2 generations of the ScMTII gene bearing transgenic and non-transgenic tobacco plants were grown hydroponically in Hoagland nutrition solution containing 0, 5 and 10 mg/L Cd in controlled growth room to determine their ability to uptake and accumulate Cd within the shoots and roots. There were no significant shoot and root dry weight differences between transgenic and non-transgenic tobacco plants. The ScMTII gene bearing transgenic tobacco plant accumulated 19.8% higher Cd than the non-transgenic tobacco plant in the above ground parts of the plant during the two weeks exposure period in hydroponic culture. In non-transgenic plant, however, Cd is accumulated mainly in the roots. The results of current study indicate that the use of the ScMTII gene bearing transgenic tobacco plant for Cd phytoremediation is limited. Further studies are needed to test the effectiveness of the ScMTII gene for phytoextraction of other heavy metal ions.

(Kahramanmaraş Sütçü İmam Üniversitesi, 2024) Eren, Abdullah; Eren, Abdullah; Bilge, Uğur; Ceylan, Ramazan; Selçuk, Ramazan; Düz, M. Zahir; Department of Organic Agriculture / Organik Tarım Bölümü
Hümik asit (HA) ile topraktaki iz elementlerin biyoyarayışlılığı, reaksiyonları ve hareketliliği arasında önemli ilişkiler bulunmaktadır. Bu nedenle topraklar, HA uygulamalarıyla kimyasal, biyolojik ve fiziksel yönden iyileştirilmeye çalışılmaktadır. Bu çalışmada, Diyarbakır yöresinden 118 adet tarımsal toprak örneklerinin hümik asit içeriklerinin bazı iz elementlerle (Al, As, Ba, Be, Cd, Fe, Mn, Pb, Sb, Sn, Se, V ve P) olan ilişkisi çok değişkenli istatistiksel analizlerle değerlendirilmiştir. Toprak örnekleri mikrodalga yaş yakma yöntemiyle çözünürleştirildikten sonra element içerikleri ICP OES (Inductively Coupled Plasma Optical Emission Spectrometer) cihazı ile belirlenmiştir. Yöntemin doğruluğu için SRM (Standard Reference Material) olarak SRM NIST 2586 kullanılmıştır. Yapılan analiz sonucunda geri kazanım değerleri %91.6 ile %105.9 arasında bulunmuştur. Hümik asit topraklardan International Society for Humic Substances (IHSS) yöntemiyle ekstrakte edilmiş, çalkalayıcı ve santifrüj cihazı kullanılarak belirlenmiştir. Yöntemin doğruluğu için Hümik Asit Sodyum Tuzu (HA-Na) ile test edilmiştir. Elde edilen veri setine Pearson korelasyonu ve kısmi korelasyon analizi uygulanmıştır. Ayrıca çoklu regresyon, HCA (Hiyerarşik Küme Analizi) ve PCA (Principal Component Analysis) gibi çok değişkenli istatistiksel analizler uygulanmıştır. Çoklu regresyon analizi Step-wise yöntemine göre yapılmıştır. Manganese ve P (p< 0.01), HA bağımlı değişken olarak alındığında önemli bulunmuştur. Pearson korelasyon katsayısına göre toprakta HA ile As (r = -0.282**) arasındaki ilişki negatif ve anlamlı iken, Fe (r = 0.185*), Mn (r =0.273**)), Sn (r = 0.242*), Se (r = 0.325**) ve P ( r = 0.315**) gibi diğer elementlerle pozitif ve anlamlı olarak belirlenmiştir. Kümeleme ve PCA analizinde HA, P Mn ve Fe’nin aynı grupta olduğu saptanmıştır. Yapılan analizler HA’in toprağın bitki besin elementleri lehinde pozitif etki yaptığını göstermiştir.
The Effect of Talaromyces funiculosus ST976 Isolated from Pistacia vera Rhizosphere on Phosphorus Solubility in Soil Samples with Different Physicochemical Properties
(Kahramanmaraş Sütçü İmam Üniversitesi Tarım ve Doğa Dergisi, 2022) Derviş, Sibel; Eren, Abdullah; Eren, Abdullah; Özer, Göksel; Department of Organic Agriculture / Organik Tarım Bölümü
In this study, a total of 78 Talaromyces isolates were isolated from the pistachio (Pistacia vera L.) rhizosphere heavily infested with Neoscytalidium spp. The identification studies of the four representative isolates based on morphological and molecular methods showed that all isolates were T. funiculosus. The 575 bp long sequence of the internal transcribed spacer region of T. funiculosus isolate ST976, selected as a representative of the isolates, was deposited in GenBank under accession no. MW130842. The Maximum Likelihood tree clustered the ST976 isolate with reference T. funiculosus isolates derived from the GenBank nucleotide database. The phosphorus dissolution ability of ST976 isolate was determined by an experiment using six soil samples collected from agricultural lands in various locations of Şanlıurfa province. The pH of the soil samples taken varied between 7.21 and 7.88. As a result of the analysis performed with the addition of the isolate ST976 applied to soil samples with different soil structures (Clay and Clay-Loam), it was determined that the isolate ST976 dissolved 109–311% more phosphorus than the control sample. The study is one of the first studies proving the ability of T. funiculosus isolate ST976 to dissolve phosphorus without any additives to soil solution was determined.

Effects of Zno Nanoparticles and Ethylenediamine-N,n Acid on Seed Germination of Four Different Plants
(John Wiley and Sons Inc, 2019) Doğaroğlu, Z.G.; Eren, Abdullah; Eren, A.; Baran, Mehmet Fırat; Department of Organic Agriculture / Organik Tarım Bölümü; Department of Medical Services and Techniques / Tıbbi Hizmetler ve Teknikleri Bölümü
The release of nanoparticles and biodegradable chelating agents into the environment may cause toxicological and ecotoxicological effects. The aim of this study is to determine the ecotoxic effects of zinc oxide (ZnO) nanoparticles and ethylenediamine disuccinic acid (EDDS) on most cultured four plants. The durum wheat, bread wheat, barley, and rye are exposed to 5 mL 10 mg L−1 ZnO nanoparticles and 10 mg L−1 EDDS in the seed germination stage. Results show that these different plant species have different responses to ZnO nanoparticles and EDDS. The germination percentage of bread wheat and rye decreases in the application of ZnO nanoparticles while the germination of durum wheat and barley increases as much as in radicle elongation and seedling vigor. While ZnO treatment causes a decrease in bread wheat and rye germinated rat in the range of 33–14.3%, respectively, there is no change in germination rate of these plants at EDDS treatment. In addition, EDDS treatment positively affects barley germination rate. In conclusion, it is clear that ZnO nanoparticles have more toxic effects on bread wheat and rye than EDDS, while barley is positively affected by ZnO nanoparticles and EDDS. © 2019 The Authors.

(Corvinus Univ Budapest, 2019) Kendal, E.; Eren, A.; Dogan, Y.; Oral, E.; Koyuncu, M.; Doğan, Yusuf; Eren, Abdullah; Kendal, Enver; Oral, Erol; Department of Plant Protection / Bitki Koruma Bölümü; Department of Organic Agriculture / Organik Tarım Bölümü; Department of Seed Production / Tohumculuk Teknolojisi Bölümü
The study was conducted to evaluate the quality of durum wheat grain. For this reason, genetic resources are crucial for the identification of parents and the enrichment of the gene pool that can be used in the development of new varieties for better nutrition of people. For this purpose, 131 populations of landraces, 9 promising line and 5 new varieties were used. The experiment was set up in randomized blocks with 7 replications, according to the augmented (increased) experimental design in 2015-2016 growing season. In the study, we examined total nitrogen content, protein ratio, CIE (Commission Internationale Eclairage) wheat color analysis (L* brightness, b* jaundice, a* redness) of 145 genotypes of durum wheat seeds. According to analysis of variance, highly significant differences (P < 0.05 or P < 0.01) were determined for total nitrogen, protein content and CIE L* value, while differences were not significant for b* value and a* value. The superiority of the genotypes was determined by the first two principal components (IPC1 (principle component) and IPC2) in order to create a two-dimensional GT biplot. The sum squares of the first two components were accounted by 45.34% (PC1) and 40.03% (PC2) for genotypes. The GT (genotype x trait) biplot indicated that 9 (nine) sectors occurred among genotypes and quality parameters. On the other hand, three groups occurred among the quality parameters based on the genotypes. The scatter plot demonstrated that there is a high correlation between b* jaundice, and a* redness. The results showed that cultivars and more landraces have general adaptability for all quality parameters, while some genotypes (G79, G78), (G22, G102), (G3) and (G121, G5) showed specific adaptation for N (nitrogen), PC (protein content) and L*, a* and b* values, respectively. According to the biplot techniques, G36 came forward with the N, P and a* value and desirable landraces, G5 for b* value, G30 stable line for all quality parameters, while (G128, G61) and the majority of promising lines (L4, L6) did not come forward with any quality parameters. The results of the study indicated that the majority of landraces can be used as parents to improve the quality of durum wheat varieties. The study indicated that GT biplot can be used to evaluate the genotypes graphically to select the best genotypes for parents to use in breeding programs.
EVALUATION OF PRODUCTIVITY STATUS OF DRY FARMING SOILS IN MARDIN PLAIN USING GEOGRAPHICAL INFORMATION SYSTEM ANALYSES
(İKSAD Publishing, 2020) Eren, Abdullah; Ayyıldız, Ahmet Şahin; Department of Organic Agriculture / Organik Tarım Bölümü; Department of Architecture and Urban Planning / Mimarlık ve Şehir Planma Bölümü
Soil fertility is among the most basic criteria for obtaining quality and abundant products in agricultural production. The physical and chemical properties of soils, the scarcity or abundance of plant nutrients are important factors affecting the yield and quality of agricultural products, and the nutrient concentrations in soils can be determined by soil analysis. In addition, depending on the physical and chemical properties of the soil, knowing the relationships between these properties and the nutrients in the soil is important in terms of providing the highest benefit of fertilisation for the plants to be grown according to the land conditions (Taban et al., 2004; Başaran and Okant, 2005; Tümsavaş and Aksoy, 2008). The product yield and quality of the grown plants are closely related to the nutrient content of the soils to meet the needs of the plants (Zengin et al., 2003; Belliturk et al., 2019). The formation of agricultural lands is the only resource that takes thousands of years, and cannot be produced or renewed. The sustainability of soils, though, is possible by examining and monitoring soil resources as adequately as possible and defining the characteristics of agricultural areas better...

Rhizobacterial application is efficient approach and process focusing less chemical fertilizers for increasing soil fertility and nutritional value of grains for different crops. This study investigated the effect of Pseudomonas fluorescens rhizobacterial application on the yield, yield components, grain quality and content of nutrition elements in wheat and in soil. Experiments were designed according to randomized complete block design with four replications in environmental conditions of Diyarbakir province, Turkey, during 2014 and 2015 growing seasons. Four treatments of Pseudomonas fluorescens rhizobacteria (control, seed inoculation, foliar application, seed + foliar) were used to investigate their effects on various aspects of wheat crop. Results of present study indicated that P. fluorescens rhizobacteria applications significantly (P=0.05) affected grain yield, Al, K, Mg, and Zn content in grain, total N, and available P, K, Fe, and Mn elements in soil. The maximum grain yield was obtained from the combined application of seed inoculation + foliar application and showed 7% higher yield than in the control. Study indicated that application of rhizobacteria has positive effect on soil productivity, yield and nutritional quality of grains.
