(Türkiye Tarımsal Araştırmalar Dergisi, 2018) Eren, Abdullah; Department of Organic Agriculture / Organik Tarım Bölümü
Antropojenik aktivite sonucu çevreye dâhil olan ağır metaller, toprak kirliliğine ve toprak kalitesinin düşmesine neden olmaktadırlar. Ağır metallerin topraktan temizlenmesi için en uygun yöntemlerden biri olan fitoremediasyon yöntemi çevre dostu ve ekonomik bir yöntemdir. Bu çalışma, yapay olarak bakır (Cu) ile kirlenmiş topraktan, Xanthium strumarium L. (pıtrak) bitkisinin, fitoekstraksiyon etkinliğini belirlemek amacıyla yapılmıştır. Farklı dozlarda (0, 100, 200, 400 ve 800 mg Cu kg-1) Cu uygulanan toprakta 45 gün boyunca sera koşullarında pıtrak (Xanthium strumarium L.) bitkisi yetiştirilmiştir. Bitkilerin başta Cu konsantrasyonu olmak üzere klorofil içeriği, biyokütle üretimi, indirgenmiş glutatyon (GSH), bazı makro [azot (N), fosfor (P), potasyum (K), kalsiyum (Ca) ve magnezyum (Mg)] ve mikro [demir (Fe), çinko (Zn) ve manganez (Mn)] besin elementi konsantrasyonları ölçülmüştür. Bakır uygulanmış bitkiler kontrol (0 mg Cu kg-1) bitkisi ile karşılaştırılmıştır. Artan dozda Cu uygulamaları, Cu ve GSH konsantrasyonları hariç diğer ölçülen parametrelerde bir azalmaya neden olmuştur. Sonuçlar, pıtrak bitkisinin, Cu ile kirlenmiş toprakların temizlenmesi için kullanılabileceğini ve fitoremediasyon yöntemine uygun olduğunu göstermiştir.
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.

(Elsevier Ireland Ltd, 2025) Faizan, Mohammad; Eren, Abdullah; Alam, Pravej; Iqbal, Sumera; Waheed, Zainab; Eren, Abdullah; Shamsi, Anas; Shahwan, Moyad; Department of Organic Agriculture / Organik Tarım Bölümü
One worldwide environmental concern is the presence of potentially hazardous elements (PTEs) in air, soil, and water resources. Arsenic is one of the PTEs that is thought to be the most poisonous and carcinogenic. Plants exposed to arsenic may experience several morphological, physiological, and biochemical changes-even at extremely low concentrations. Arsenic toxicity to plants varies with its speciation in plants (e.g., arsenite, As(III); arsenate, As(V)), with the kind of plant species, and with other soil parameters affecting arsenic accumulation in plants, according to new study on arsenic in the soil-plant system. Arsenic stress modifies metabolic cascades in plants at different developmental stages by affecting the pattern of gene expressions mediated by small non-coding RNAs (micro-RNAs), which are essential for plant adaptation to oxidative stress and play a key role in the moderation of numerous cellular processes. In this review, we investigated the impact of calcium (Ca2 +) on the toxicity of arsenic in plant and soil environments. Plant grown with arsenic exhibited enhanced arsenic uptake, increased oxidative stress and growth inhibition. Arsenic toxicity modulates carbohydrate, lipid, and protein metabolism along with DNA structure. Role of Ca2+, Ca channels and Ca sensors to signaling pathways also described briefly. A worldwide issue for humanity is the poisoning of soil ecosystems by arsenic. Its toxicity, tolerance, and phytoremediation of polluted soils utilizing calcium were the main points of the recent review, which also highlighted the significant mechanisms of arsenic in soil-plant systems.
The Determination of Phytoextraction Capacity Using Lavender (lavandula Latifolia) Plant in Nickel-Contaminated Soils
(2024) Eren, Abdullah; Eren, Abdullah; Department of Organic Agriculture / Organik Tarım Bölümü
This study was conducted to evaluate the suitability of Lavender (Lavandula latifolia) plant for the remediation of soils contaminated with nickel (Ni). The Lavender plant has the potential to clean contaminated soils by absorbing pollutants through a method called phytoextraction. In the research, Ni-contaminated soils were prepared under controlled conditions, and Lavender plants were grown in these soils. The growth and development of the plants were monitored, and it was investigated whether the plants absorbed Ni from the soil and accumulated it on the plant. Increasing doses of Ni (0-200-400-600-800 mg kg-1) were applied in solution form, and pot soils were incubated for one week at 60-65% of field capacity. Then, seedlings in peat medium were transferred to pots and grown under controlled conditions for 6 weeks. It was determined that the plant age, fresh and dry weight, and height increased with 200 and 400 mg Ni kg-1 applications compared to the control groups, while there was a decrease with 600 and 800 mg Ni kg-1 applications. The lowest concentrations of Ni (mg kg-1) in plants and Ni content (μg plant- 1) were observed in the control group (0 mg Ni kg-1), while the highest values were found in the 800 mg Ni kg-1 application. It was found that the concentrations of 400 mg Ni kg-1 (124 μg plant-1), 600 mg Ni kg-1 (137 μg plant-1), and 800 mg Ni kg-1 (150 μg plant-1) exceeded critical levels for plants, yet the plants remained alive at these concentrations. The phytoextraction ability of plants refers to their ability to absorb and retain harmful or polluting substances from the soil. Lavender may be among the plants that have phytoextraction potential for metals like Ni. However, the phytoextraction ability can vary depending on the species of the plant, growth conditions, and the pollutant applied. The research results demonstrated that the Lavender plant effectively absorbed Ni from the soil and accumulated it on the plant. This suggests that Lavender can be used for the remediation of soils contaminated with Ni.

(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.

(APPLIED ECOLOGY AND ENVIRONMENTAL RESEARCH, 2019) Eren, Abdullah; Department of Organic Agriculture / Organik Tarım Bölümü
Nowadays the environmental pollution caused by heavy metals is spreading all over the world, especially where the industry is developing rapidly, and soils are polluted very dramatically and hazardously at a high level. In this study, cocklebur-(Xanthium strumarium L.) plants were grown in nickel (Ni) contaminated soil (0, 50, 100, 200 and 400 mg Ni kg-1) under greenhouse conditions for 6 weeks to study the ability of Ni uptake and accumulation of the plants. The Ni treated plants were compared with the control (0 mg Ni kg-1) plant. As a result of that comparison, chlorophyll levels of old and young leaves, dry weights, reduced glutathione (GSH), macronutrient concentrations, such as nitrogen (N), phosphor (P), potassium (K), calcium (Ca) and magnesium (Mg)) and micronutrient concentrations, such as iron (Fe), zinc (Zn), and manganese (Mn) nutrient concentrations of the plants were decreased, whilst the concentrations of Ni and of copper (Cu) increased with increasing dose of Ni application. The results show that the studied plant (Xanthium strumarium L.) can be used for the cleaning up of Ni-contaminated soils and is suitable for phytoremediation.

(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.

Nanotechnology is a research subject in many interdisciplinary engineering fields today. Nanoparticles have important effects on seed germination and seedling growth of plants. The aim of this study has been to produce a 54.68 nm-sized ZnO nanoparticle obtained from the Nigella sativa L. plant by green synthesis. The effect of medicinal sage (Salvia officinalis L.) on germination of plant seeds and seedling growth was investigated. The trial was set up under controlled conditions and conducted for 14 days according to a factorial trial design with 5 replications for each dose (0, 0.5, 1.5 and 2.5 mg ZnO NP kg-1). As a result of ZnO NP application in different doses, germination of Salvia officinalis L. seeds varied between 90-94%, stem length was 1.86-2.92 cm and shoot length was between 1.01-1.98 cm. The highest root and shoot length was obtained after the application of 2.5 mg ZnO kg-1 NP. In the light of the results, ZnO nanoparticles are thought to be useful for seed development and agricultural applications.

(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...

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.

(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.

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.
