Characterization of cereal cyst nematodes in wheat using morphometrics, SCAR markers, RFLP, and rDNA-ITS sequence analyses

Şenol YILDIZ

In this study, morphological and molecular characterizations of twenty-four Heterodera populations (cereal cyst nematodes, CCNs) collected from wheat production fields in Turkey were carried out. Light microscopy, species-specific markers, RFLP, and ITS sequencing were used to identify the nematode populations. The obtained CCN populations were identified as Heterodera avenae, H. filipjevi, and H. latipons according to the morphometric analysis, which was confirmed by the molecular techniques. The ITS region sequencing analysis confirmed the species identification, and phylogenetic analysis of ...More

An app for apples: Citizen-led mapping of fire blight in Central Asia

Saykal BOBUŞOVA | Tinatin DOOLOTKELDİEVA

Fire blight, caused by the bacterial pathogen Erwinia amylovora, is a severe bacterial disease of apple and pear that can quickly destroy whole plants. In the last decade, it was also detected in Central Asia, where wild pomaceous fruit plants represent the dominant species in mid-altitude forests and constitute a critical foundation for the entire ecosystem. Efficiently informing farmers, forestry services and private persons about the instances and dangers of fire blight, the correct way to recognize the symptoms, and the methods of disease control is thus of paramount importance in a vast a ...More

The effects of the investment decisions of telecommunications firms on their financial performance during the COVID-19 pandemic

Gökhan ÖZER

In this paper we examine how the financial performance of telecommunications firms is affected by the COVID-19 pandemic, and investigate the role of capital expenditures in this relationship. The full sample consists of 383 unique telecommunications firms from 72 countries. Empirical models are estimated using ordinary least squares regression with the Driscoll–Kraay standard errors method. We find that the financial performance of telecommunications firms, on average, decreased slightly during the pandemic period. However, firms with higher capital expenditures have increased their financial ...More

Soil–Plant Interactions in the High-Altitude Ecosystems: A Case Study from Kaz Dağı (Mount Ida), Turkey

Zeki SEVEROĞLU

Kaz Dağı, the ancient Mount Ida, is a mountainous area and one of the important biodiversity spots, located in the north of Edremit in northwestern Anatolia. The area abounds in fertile soils, wetlands, underground resources, favorable climatic conditions, interesting geomorphological characteristics, and several world famous archeological and cultural places. Southwestern part of the mountain has been declared as a national park in 1993, which hosts a very rich and diverse flora including many endemic and rare species; a majority of these are of great economical and ethnobotanical significanc ...More

Dynamics of Microbiological Diversity of Soils in the Chu Valley during Land Use Change in Pastures

Nurzat TOTUBAYEVA

Soil microflora is one of the first to feel a negative impact and can serve as a biological indicator of changes in the soil structure and the degree of impact on the soil ecosystem. In 2020, studies were carried out at two sites located in the Shamshy Gorge in the Chui region of the Kyrgyz Republic. One of the plots was withdrawn from pasture use for one year in 2020 and two years in 2019 as compared to the actively used control option. The microbiological diversity was studied with conventional methods of microbiology. The micromycetes of the studied soils were represented in the dominance o ...More

Potential of Turkish Beauveria bassiana isolates for the management of the polyphagous planthopper, Orosanga japonica Melichar 1898 (Hemiptera: Ricaniidae)

İsmail ERPER

Background Entomopathogenic fungi are a potential biological control agent for many pests. In this study, 14 native Beauveria bassiana isolates were molecularly identified and assessed for their virulence and mortality against adults of the polyphagous planthopper Orosanga japonica, Melichar (Hemiptera: Ricaniidae) a polyphagous sap-feeding insect, under laboratory conditions. Results Isolates obtained from naturally infected adults O. japonica were molecularly identified as B. bassiana by sequencing the internal transcribed spacer and 26S large subunit of ribosomal DNA. In the bioassay, the r ...More

Volatility of the alternative energy input prices and spillover effects: a VAR [MA]-MGARCH in BEKK approach for the Turkish economy

Tezcan ABASIZ

The interaction among the energy unit prices, which are considered as the most effective factor on the realization of economic growth, and the distribution of this interaction throughout the manufacturing process have become popular subjects in research recently. Especially, the scarcity of energy resources and the problems encountered in their supply make it necessary to utilize alternative energy resources. Thus, the realization of production using different energy inputs simultaneously results in an interaction between the factors and the spillover effect. Thus, in the study, alternative ve ...More

Tuta absoluta continues to disperse in Asia: damage, ongoing management and future challenges

Tair Esenalı Uulu

Since its initial detection in Turkey in 2009, the invasive destructive pest South American tomato pinworm Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) has started its new invasion journey to east and invaded most Asian countries. This pest currently causes extensive damage to tomato production and potentially threatens key production areas such as China. To provide an overview of current status of T. absoluta in Asia, we have briefly reviewed the damage and economic impacts by this pest locally and discussed why this species has spread so rapidly among the countries. Moreover, ongoing i ...More

Investigation of changes in rheological properties during processing of fermented cereal beverages

Canıl İSKAKOVA | Camilya SMANALİYEVA

Many indigenous fermented foods and beverages consumed throughout the world are produced at home or in crafts enterprises. The production of fermented beverages on a large commercial or industrial scale requires clearly established technical and technological requirements. This study shows a novel way to investigate the optimal process parameters of the Kyrgyz traditional fermented beverage Bozo using rotational rheological parameters. Five significant process parameters were investigated like cooking of millet porridge, the mashing temperature, the mashing time under conditions of mixing and ...More

Isolation and genetic characterization of Erwinia amylovora bacteria from Kyrgyzstan

Tinatin DOOLOTKELDİEVA | Saykal BOBUŞOVA | Mahabat KONURBAYEVA

Fire Blight, an economically relevant disease of apple, pear, and quince trees that is caused by the Gram-negative bacterium Erwinia amylovora, was first reported from Kyrgyzstan in 2008. One decade later, the disease has spread across the northern part of the country, affecting fruit orchards mainly in Chuy and Issyk-kul regions. Using semi-selective cultural media, bacteria have been isolated from plant material sampled in infested orchards from different locations in Kyrgyzstan, and 16S rRNA gene sequence determination together with diagnostic PCR have been used to identify E. amylovora bac ...More

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 ...More
