(Springer Science and Business Media Deutschland GmbH, 2023) Yiğit, Uğur; Türkkan, Muharrem; İlhan, Hasan; Şimşek, Tuncay; Güler, Ömer; Derviş, Sibel
This study aimed to evaluate the antifungal activity of copper-boron (Cu-B) nanoalloys against a range of Phytophthora species, including P. capsici, P. citrophthora, P. palmivora, P. cinnamomi, P. nicotianae, P. cactorum, P. plurivora, P. inundata, and P. megasperma. The nanoalloys were synthesized via mechanical alloying under an argon atmosphere, resulting in the formation of nanocrystalline Cu-B nanoalloys with irregular morphology and particle sizes ranging from 50 to 240 nm. At a concentration of 250 µg mL−1, the Cu-B nanoalloys demonstrated complete inhibition of mycelial growth, sporangium production, and zoospore germination in all tested Phytophthora species. The EC50 values for mycelial growth ranged from 28.02 to 120.17 µg mL−1, while for sporangium production and zoospore germination, they were below 10 µg mL−1. Furthermore, the nanoalloys exhibited fungicidal activity against specific Phytophthora species, such as P. capsici, P. citrophthora, P. inundata, and P. megasperma, at concentrations of 100, 250, 250, and 250 µg mL−1, respectively. Notably, the Cu-B nanoalloys displayed significant protective and curative effects on tuber rot severity in P. nicotianae-inoculated potatoes, resulting in reductions of 94.13% and 92.61% compared to the control, respectively, at a concentration of 10 µg mL−1 (P < 0.05). These findings highlight the potential of Cu-B nanoalloys as a promising fungicide for the management of plant diseases caused by Phytophthora spp.

Deneme sonucunda fener otu ve sığırkuyruğu bitkilerinin ağır metallerle kirlenmiş toprakların temizlenmesinde kullanma potansiyellerinin olduğu tespit edilmiştir.
Bakırla Kirlenmiş Toprakların Xanthium strumarium L. Bitkisi Kullanılarak Fitoremediasyonu
(Türkiye Tarımsal Araştırmalar Dergisi, 2018) Eren, abdullah
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) Dağhan, Hatice; Arslan, Mehmet; Uygur, Veli; Köleli, Nurcan; Eren, abdullah
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.
THE EFFECTS OF NICKE L APPLICATIONS ON TH E GROWTH OF COCKLEBUR ( XANTHIUM STRUMARIUM L.) PLANT
(APPLIED ECOLOGY AND ENVIRONMENTAL RESEARCH, 2019) Eren, abdullah
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.
Effects of ZnO Nanoparticles and Ethylenediamine-N,N′- Disuccinic Acid on Seed Germination of Four Different Plants
(Wiley Online Library, 2019) Doğaroğlu, Zeynep Görkem; Eren, Abdullah; BARAN, Mehmet Fırat
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.

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
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.
INVESTIGATING ANTIMI CROBIAL ACTIVITY OF SILVER NANOPARTICLES PRODUC ED THROUGH GREEN SYN THESIS USING LEAF EXTRACT O F COMMON GRAPE ( VITIS VINIFERA
(2019) Acay, Hilal; Baran, Mehmet Fırat; Eren, Abdullah
In this study, a direct approach to fabricating silver nanoparticles (AgNPs) via the leaf extract of common grape (Vitis vinifera) has been demonstrated. The produced particles were found with a maximum wavelength of 452.47 nm, spherical shape and the crystal size of 18.53 nm through UV-Visible spectrophotometry, XRD (X-ray diffraction) and SEM (Scanning electron microscopy) characterization methods. Furthermore, the functional groups involved in the reduction were specified with FTIR (Fourier transform infrared spectroscopy), the elemental compounds were identified with EDX (Energy dispersive X-Ray spectroscopy) and the degradation points were determined with TGA-DTA (Thermal gravimetric analysis) methods. AgNPs were found to be effective against hospital pathogens, namely Gram-negative Escherichia coli ATCC 25922, Gram-positive Staphylococcus aureus ATCC 29213 and Candida albicans fungus at the concentrations of 0.314, 0.078 and 0.334 g mL-1, respectively.

Organik Tarımda Üreticilerin Karşılaştıkları Sorunlar (Mardin İli Örneği)
(Bahri Dağdaş Bitkisel Araştırma Dergisi, 2018) Acıbuca, Veysi; Eren, abdullah; Bostan Budak, Dilek
Türkiye’de organik tarım faaliyetleri 1980’li yıllardan itibaren hızlı bir şekilde gelişme göstermiş olup, 2002 yılı ile 2016 yılları arasında organik tarım yapılan alanlarda yaklaşık 10 kat artış olmuş, aynı dönemde organik tarımsal üretim 300 000 tondan yaklaşık 2.5 milyon tona yükselmiştir. Ancak Türkiye’nin organik ürün üretiminde sahip olduğu fırsatlar göz önüne alındığında, söz konusu rakamlar mevcut potansiyelin tam olarak kullanılmadığını göstermektedir. Organik ürün üretiminin yaygınlaştırılması için yayım faaliyetlerinin yapılması önemli olduğu kadar, mevcut organik üretim faaliyetlilerinin devam ettirilmesinde üreticilerin sorunlarının tespit edilmesi ve bu sorunların çözümü konusunda öneriler sunulması da önem taşımaktadır. Bu çalışmada 2017 yılında Mardin ili ve ilçelerinde organik tarım faaliyetlerinde bulunan üreticilerin sosyo-ekonomik durumları ve sorunlarının tespiti amacıyla yüz yüze görüşme ve telefon yöntemiyle anket uygulaması yapılmıştır. Bu amaçla 2017 yılında çiftçi kayıt sisteminde bulunan 89 üreticiden 52 tanesine ulaşılmıştır. Elde edilen verilere SPSS 22.00 versiyonu kullanılarak frekans, yüzde ve parametrik olmayan testlerden Mann-Whitney U analizleri yapılmıştır. Araştırma sonucuna göre çiftçilerin yaş ortalamasının yüksek ve eğitim düzeyinin düşük olduğu belirlenmiştir. Üreticilerin tamamına yakın kısmının bağcılık faaliyetinde bulunduğu, %50’sinin 20 dekar ve altındaki alanlarda organik tarım yaptığı tespit edilmiştir. Anket yapılan üreticilerin en önemli sorunlarının pazarlama sorunları, sözleşmeli üretimin olmaması, kullanılan ilaçların etki etmemesi ve yetiştirme teknikleri konusundaki bilgi eksikliği olduğu gözlenmiştir. Üreticilerin organik tarımla ilgili önemli sorunlarının olduğu ancak desteklemelerden faydalanma amaçlı organik tarıma devam etmeyi düşündükleri, hastalık ve zararlılarla mücadele konusunda bilgi eksikliklerinin olması ve üretim tekniklerini bilmemelerinin de elde ettikleri gelirin düşük olmasına neden olduğu düşünülmektedir. Özellikle sadece bir sorunla karşılaştıklarında bilgi edinme kaynaklarından faydalanmaları üreticilere yönelik yayım faaliyetlerinin arttırılmasını önemli kılmaktadır.
Phytoextraction of Nickel Contaminated Soil with Citric Acid and Humic Acid treatments using Rosemary (Rosmarinus officinalis) Plant
(International Journal of Environmental Sciences & Natural Resources, 2019) Eren, abdullah
In this study, the removal possibilities of Ni from contaminated soil using perennial rosemary (Rosmarinus officinalis) plants were investigated. This decontamination process was conducted adding citric acid (C6H8O7) and humic acid. Increasing dose of Ni (0, 50, 100, 200 and 400mg Ni kg-1), 0.005mM citric acid and 2% humic acid were added to the test soil in the pots and incubated under controlled conditions for a month. The seedlings of rosemary plant were transferred to the pots and they were grown for 45 days. At the end of the experiments, dry weight of plant tissues and the concentrations of Ni, nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), zinc (Zn), manganese (Mn), and copper (Cu) were determined. The treatments of citric acid and humic acid were increased the Ni uptake of plants. As a result of the experiments, it has been determined that the rosemary plant has accumulated 189μg plant-1 in 400mg Ni kg-1 application, and 246g plant-1 in 400mg Ni kg-1 + citric acid application and 216μg plant-1 in 400mg Ni kg-1 + humic acid application. The results showed that the rosemary plant has the potential phytoextractor plant in decontamination process with citric acid and humic acid.
Phytopythium litorale: A novel killer pathogen of plane (Platanus orientalis) causing canker stain and root and collar rot
(Plant Disease, 2020) Derviş, Sibel; Türkölmez, Şahimerdan; Çiftçi, Osman; Özer, Göksel; Serçe, Çiğdem Ulubaş; Dikilitaş, Murat
Decline symptoms associated with lethal stem and branch canker stain along with root and collar rots were observed on 5- to 7-year-old roadside oriental plane trees (Platanus orientalis) in Diyarbakır, Turkey. Above-ground symptoms included leaf necrosis, leaf curling, extensive bluish or blackish staining of shoots, branches, stem bark, and wood surfaces, as well as stem cankers and exfoliation of branch bark scales. A general decline of the trees was distinctly visible from a distance. A Phytophthora/ Pythium-like oomycete species with globose to ovoid, often papillate and internally proliferating sporangia was consistently isolated from the fine and coarse roots and stained branch parts and shoots. The pathogen was identified as Phytopythium litorale based on several morphological features. Partial DNA sequences of three loci, including nuclear rDNA internal transcribed spacer (ITS) and the large ribosomal subunit (LSU), and mitochondrial cytochrome c oxidase subunit II (coxII) confirmed the morphological identification. All P. litorale isolates were homothallic, developing gametangia, ornamented oogonia with elongate to lobate antheridia. Pathogenicity of P. litorale was tested by inoculation on excised shoots and by root inoculation on seedlings. P. litorale produced large lesions and blights on shoots in just 5 days and killed 100% of the seedlings in a month. This paper presents the first confirmed report of P. litorale as an important pathogen on a plant species causing branch and stem cankers, and root and collar rot, in and on P. orientalis, resulting in a rapid decline of trees and suggesting a threat to plane.
Plant-Associated Neoscytalidium dimidiatum-Taxonomy, Host Range, Epidemiology, Virulence, and Management Strategies: A Comprehensive Review
(MDPI, 2023) Derviş, Sibel; Özer, Göksel
Neoscytalidium dimidiatum, a plant- and human-associated fungus, has emerged as a substantial global ecological and agricultural threat aggravated by global warming. It inflicts various diseases, including canker, blight, dieback, leaf spot, root rot, and fruit rot, across a wide spectrum of fruit trees, field crops, shrubs, and arboreal species, with a host range spanning 46 plant families, 84 genera, and 126 species, primarily affecting eudicot angiosperms. Six genera are asymptomatic hosts. Neoscytalidium dimidiatum exhibits worldwide distribution, with the highest prevalence observed in Asia and North America, notably in Iran, Turkey, and California. Rising disease prevalence and severity, aggravated by climate change, particularly impact tropical arid places across 37 countries spanning all 7 continents. This comprehensive review encapsulates recent advancements in the understanding of N. dimidiatum, encompassing alterations in its taxonomic classification, host range, symptoms, geographic distribution, epidemiology, virulence, and strategies for effective management. This study also concentrates on comprehending the taxonomic relationships and intraspecific variations within N. dimidiatum, with a particular emphasis on N. oculus and N. hylocereum, proposing to consider these two species as synonymous with N. dimidiatum. Furthermore, this review identifies prospective research directions aimed at augmenting our fundamental understanding of host-N. dimidiatum interaction.

(Yüzüncü Yıl Üniversitesi Tarım Bilimleri Dergisi, 2018) Kılıç, Hasan; Eren, Abdullah; Köleli, Nurcan
In this study, the use of Rosmarinus officinalis was investigated to clear soil contaminated with Cd. The soil sample for pot experiment is taken from the old municipal waste storage in Mardin. The pot experiment conducted in the greenhouse. Increasing dose of Cd (0-5-10-20 mg kg-1 as 3CdSO4.7H2O form) and 0.005 mM citric acid applied to the soil and all pots were incubated for 30 days. The fertilizer (200 mg N kg-1) applied before seedling and then plant seedlings transferred to the pots. The plants were grown for 45 days in the greenhouse. After harvest Cd, N, P, K, Mn, Fe, Cu, and Zn concentrations of plant samples were determined in ICP-MS. The highest Cd content (8.31 μg plant-1) was obtained in 20 mg Cd kg-1 treatments. The result of the experiment was shown that the Rosmarinus officinalis was not suitable for pyhtoextraction of Cd-contaminated soils.
