Construction, characteristics and high throughput molecular screening methodologies in some special breeding populations: a horticultural perspective

Hasan CAN | İbrahim İlker ÖZYİĞİT | Mustafa PAKSOY

Advanced marker technologies are widely used for evaluation of genetic diversity in cultivated crops, wild ancestors, landraces or any special plant genotypes. Developing agricultural cultivars requires the following steps: (i) determining desired characteristics to be improved, (ii) screening genetic resources to help find a superior cultivar, (iii) intercrossing selected individuals, (iv) generating genetically hybrid populations and screening them for agro-morphological or molecular traits, (v) evaluating the superior cultivar candidates, (vi) testing field performance at different location ...Более

Inhibitory effects of allelopathic crops on seedling growth of weed Hypericum triquetrifolium Turra

İbrahim İlker ÖZYİĞİT

In Laboratory bioassays and Pot culture, we determined the effects of aqueous extracts of 7-allelopathic crops [Alfalfa (Medicago sativa L.), Sorghum (Sorghum bicolor L.), Sunflower (Helianthus annuus L.), Rape (Brassica napus L.), Rye (Secale cereal L.), Barley (Hordeum vulgare L) and Oat (Avena saliva L)] on the seedling growth of weed Hypericum triquetrifolium. In first Lab. bioassay, barley and rape were found most phytotoxic to Hypericum seedlings growth. Then these two crops effects were further tested in pot experiments, with different residues rates (R1, R2, R3 for rape and B1, B2, B3 ...Более

Heavy Metal Levels and Mineral Nutrient Status in Different Parts of Various Medicinal Plants Collected from Eastern Mediterranean Region of Turkey

İbrahim İlker ÖZYİĞİT

Medicinal plants have been used for treatment of many diseases since the ancient times with traditional knowledge being transferred from generation to generation. However, in recent years, many natural habitats have been contaminated due to increased anthropogenic activities. Plants which are exposed to heavy metal toxicity may experience several serious problems. Furthermore, the inclusion of these plants into the food chain poses a threat to human health as well. Additionally, presence of heavy metals directly effect mineral nutrition and consequently the food quality. The aim of this study ...Более

Some Heavy Metals and Mineral Nutrients of Narrow Endemic Cirsium Byzantinum Steud., From Istanbul, Turkey: Plant-Soil Interactions

İbrahim İlker ÖZYİĞİT | Gülbübü KURMANBEKOVA

Cirsium species have economic importance because of their botanical and medicinal properties. Thus, this study has aimed to investigate some heavy metal (Fe, Mn and Zn) and mineral nutrient (B, Ca, K, Mg and Na) status of narrow endemic Cirisum byzantinum. Plant and soil element concentrations were analyzed by using ICP-OES and the evaluation of plant-soil interactions for heavy metals and mineral nutrients were carried out by statistical methods. The measured element concentrations (in mg/kg) were in ranges of 5.936-19.044 for B, 1862.161-4811.168 for Ca, 12.610-38.474 or Fe, 3421.383-6881.88 ...Более

GENETIC DIVERSITY AND PHYLOGENETIC ANALYSES OF TURKISH RICE VARIETIES REVEALED BY ISSR MARKERS AND CHLOROPLAST trnL-F REGION

İbrahim İlker ÖZYİĞİT

A set of 17 Turkish rice (Oryza sativa L.) varieties (TRVs) were characterized using inter simple sequence repeat (ISSR) markers to study genetic diversity. Also, the sequences of trnL((UAA))-F-(GAA) intergenic spacer (IGS) regions were used to evaluate the phylogenetic relationships of TRVs. According to ISSR data, the observed number of alleles (Na), effective number of alleles (Ne), Nei

Heavy metals and trace elements detected in the leaves of medicinal plants collected in the southeast part of Turkey

İbrahim İlker ÖZYİĞİT

The present study focused on the heavy metal and essential element contents that were detected in 37 different plants for making assessments to reveal possible heavy metal contamination and its effects on plant and human health. These plants having medicinal properties are used widely in the southeast part of Turkey. ICP-OES was employed for the determination of Al, B, Ca, Cd, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, and Zn concentrations in the leaves of some selected medicinal plants. The concentration rates (in mg kg(-1)) obtained in ascending order were as in the following ranges: 8.68-278.83 fo ...Более

Economic Impacts of Bt (Bacillus thuringiensis) Cotton

İbrahim İlker ÖZYİĞİT

In recent years, high-yield production has gained importance due to the decrease in agricultural fields in the world and the rapid increase in the population. Cotton is an important source of income for farmers worldwide and is an important crop, especially for the textile industry. Bt-cotton technology, which entered our lives in 1996, has been quickly adopted in many developed and developing countries. It has been shown to provide advantages in many areas. In particular, the economic growth is gaining importance every year. Additionally, it has also brought an environmentally friendly soluti ...Более

Lemna minor, a hyperaccumulator shows elevated levels of Cd accumulation and genomic template stability in binary application of Cd and Ni: a physiological and genetic approach

İbrahim İlker ÖZYİĞİT

In this study, to determine whether having potential to be used as hyperaccumulator for Cd and Ni, numerous experiments were designed for conducting assessments for physiological and genotoxic changes along with defining possible alterations on mineral nutrient status of Lemna minor L. by applying Cd-Ni binary treatments (0, 100, 200 and 400 mu M). Our study revealed that there were increases in the concentrations of B, Cr, Fe, K, Mg, and Mn whereas decreases were noticed in the concentrations of Na and Zn and the levels of Ca were inversely proportional to Cd-Ni applications showing tendency ...Более

Multidimensional Scaling of the Mineral Nutrient Status and Health Risk Assessment of Commonly Consumed Fruity Vegetables Marketed in Kyrgyzstan

Hasan CAN | İbrahim İlker ÖZYİĞİT

Intensive production of fruits and vegetables causes heavy metal accumulation. Consumption of this kind of foodstuff is a growing concern of the modern world with the additional distress of the supply of enough foodstuffs. To contribute to this global purpose, this research aimed to find out the mineral nutrient and heavy metal concentrations of commonly consumed fruity vegetables in Kyrgyzstan. Totally, ten different fruity type vegetables were collected from five different large bazaars of Kyrgyzstan. From these, 20 samples, including washed/unwashed rinds of vegetables, were quantified in t ...Более

Assessment of pollution at the former uranium waste dumpsite near kaji-Say Village/Kyrgyzstan: a genetic and physiological investigation

İbrahim İlker ÖZYİĞİT | Bermet KIDIRALİYEVA | Kadırbay ÇEKİROV | Gülbübü KURMANBEKOVA | Nurzat ŞAYKİYEVA

Kyrgyzstan still suffers from the past practices of radioactive industry operated by the Soviet Union that caused significant impact on ecosystems in this region, especially related with storage of uranium in inadequate conditions. There are at least 50 abandoned sites used as radioactive waste dumps in the country. Due to the pressure of natural and anthropogenic reasons, the structural foundations of mine waste dumps are gradually losing their integrities. Here, particular interest of our research is to reveal current state of radioactive contamination and to make evaluation on the radiologi ...Более
