Genetic Relationships and Population Structure of Central Asian Apple Species collected from Different Parts of Kyrgyzstan

Abdıkerim ABDULLAYEV

Apple is among the most widely grown fruit species worldwide. It is included in the genus Malus and there are several species of apple. Although a consensus is not available about the origin of domesticated apples, it is widely accepted that Malus sieversii, known as Central Asia wild apple, was the primary progenitor of apples. Central Asia is a quite significant origin center of apple and harbors different species and a great diversity. In this study, genetic relations among 79 apple materials belonging to 4 different species (M. domestica, M. sieversii, M. kirghisorum and M. niedzwetzkyana) ...More

Efficacy of the entomopathogenic fungi; Beauveria bassiana and Metarhizium anisopliae against the cowpea weevil, Callosobruchus maculatus F. (Coleoptera: Chrysomelidae: Bruchinae)

İsmail ERPER

The efficacy of the two entomopathogenic fungi, Metarhizium anisopliae (TR 106) and Beauveria bassiana (TR 217), was tested against the adults of the cowpea weevil, Callosobruchus maculatus F. (Coleoptera: Chrysomelidae: Bruchinae) in laboratory. Two concentrations of conidial suspensions (1 x 10(6) and 1 x 10(8) conidia/ml) of M. anisopliae and B. bassiana isolates were directly applied on four pairs of adult beetles in Petri dishes (2 ml/dish) and then incubated at two different climatic regimes; 22 +/- 1 degrees C and 26 +/- 1 degrees C with 70 +/- 5% RH, 16:8 h light-to-dark. Lethal time v ...More

Investigation of nutritional characteristics and free radical scavenging activity of wild apple, pear, rosehip, and barberry from the walnut-fruit forests of Kyrgyzstan

Canıl İSKAKOVA | Cıldız ÖSKÖNBAEVA

This study is based on 2-year experimental results aimed at evaluating the nutritional value and pomological characteristics of wild fruits and berries from the walnut-fruit forests of southern Kyrgyzstan including apple (Malus sieversii var. kirgizorum), pear (Pyrus korshinskyi Litv.), rosehip (Rosa canina), or barberry (Berberis oblonga). Wild pear, characterised by its high level of alimentary fibres (8.76 g/100 g), offers a promising potential for industrial pectin production. Barberry features higher radical scavenging activity (antioxidant activity) as compared to Iranian and Turkish eco ...More

MOLECULAR IDENTIFICATION OF COTTON WHITEFLY BEMISIA TABACI GENN. (HEMIPTERA: ALEYRODIDAE) POPULATIONS OF TURKEY BASED ON MITOCHONDRIAL CYTOCHROME OXIDASE SUBUNIT I

Hüseyin GÖÇMEN

The cotton whitefly (Bemisia tabaci Genn.) is a major pest of cultivated plants in tropical and subtropical regions. In this study, the genetic diversity between populations and various biotypes of B. tabaci collected from Hatay, Adana, Icel, Antalya, Mugla, Aydin and Denizli provinces of Turkey were investigated using mitochondrial cytochrome oxidase subunit 1 (mtCOI) sequences. Thirty-two nucleotide variations were found in a 617 bp mtCOI sequence of the among the populations studied. Phylogenetic analysis divided the B. tabaci populations of Turkey into two groups clustering around the main ...More

Exploration of two major boron transport genes BOR1 and NIP5;1 in the genomes of different plants

İbrahim İlker ÖZYİĞİT

Boron (B) is an essential plant micronutrient but studies regarding its transport are still limited to a few plants. This work identified two major B transport sequences in plants, NIP5;1 boric acid channel protein and BOR1 transporter. 80 BOR1 and 34 NIP5;1 homologs were identified in 18 different plant genomes. BOR1 homologs had a HCO3-transporter domain, 649-737 amino-acid residues with mainly basic nature, putative 8-11 transmembrane domains (TMDs) and 11-13 exons. NIP5;1 homologs had a MIP family domain, 294-311 amino-acid residues with basic nature, 5-6 putative TMDs and 3-5 exons. Tyros ...More

Some Morphological Characteristics of Gene Pool from the Hybridization of Local Tomato Genotypes and Some Commercial Types

Mustafa PAKSOY | Önder TÜRKMEN

Determination of different gene sources is important for plant breeding studies; therefore, local genotypes are of interest. In this study, collected genotypes were hybridizied with commercial genotypes in order to transfer some traits such as disease resistance and long shelf life to local genotypes. After that, obtained genotypes were self pollinated twice and gene pool was created according to some morphological traits. Nine different groups were created from combinations according to result of clustering analysis. Result of principal component analysis (PCA) revealed that total rate of 65. ...More

Alternative Bioremediation Agents against Haloacids, Haloacetates and Chlorpyrifos Using Novel Halogen-Degrading Bacterial Isolates from the Hypersaline Lake Tuz

Yılmaz KAYA

The indiscriminate use of chemical pesticides alongside the expansion of large-scale industries globally can critically jeopardize marine ecology and the well-being of mankind. This is because the agricultural runoffs and industrial effluents eventually enter waterways before flowing into highly saline environments i.e., oceans. Herein, the study assessed two novel bacterial isolates,Bacillus subtilisstrain H1 andBacillus thuringiensisstrain H2 from the hypersaline Lake Tuz in Turkey to degrade recalcitrant haloalkanoic acids, haloacetates and chlorpyrifos, and consequently, identify their opt ...More

The utility ofTrichodermaspp. isolates to control ofXylosandrus germanusBlandford (Coleoptera: Curculionidae: Scolytinae)

İsmail ERPER

The invasive ambrosia beetle,Xylosandrus germanusBlandford (Coleoptera: Curculionidae: Scolytinae), is a serious pest of hazelnut in Turkey, which is the biggest hazelnut producer in the world. In this study, the utility of four isolates representing differentTrichodermaspecies (T. harzianum,T. hamatum,T. asperellum, andT. atroviride) was evaluated on survival, gallery behavior and brood production ofX. germanusby effecting the symbiotic fungal development at laboratory conditions. Hazelnut branches were exposed to fungal suspensions (1 x 10(6)and 1 x 10(8)conidia mL(-1)doses) for about 30 s. ...More
