An acid, 2,2-dichloropropionic acid (2,2-DCP) is an active ingredient in herbicide (Dalapon®). Using 2,2-DCP as a model substrate, an alkalotolerant bacterium was successfully isolated from the Blue Lake, Turkey. This bacterium is a potential bioremediation agent of recalcitrant xenobiotic halogenated compounds. This study aimed to prove the efficacy of the alkalotolerance Bacillus megaterium BHS1 in degrading 2,2-DCP as the sole source of carbon. Biolog GEN III system and 16S rRNA analysis were used for the identification of the bacterium. It was discovered that the strain BHS1 is Bacillus m ...Daha fazlası
The plant diseases caused by the Pseudomonas syringae сomplex bacteria are economically important and occur worldwide on various plants, and it is as a pathogen that has not been the object of studies and little is known about its epidemiology in Kyrgyzstan. The conventional phenotypic (LOPAT, API tests) and PCR-assisted isolation were used for the identificationof Pseudomonas syringae pv. syringaе isolates from the affected organs of local stone fruits, such as peach (Prunus persica), cherry (Prunus subgen), apricot (Prunus armeniaca), and plum (Prunus salicina) samples taken from the Chy, Is ...Daha fazlası
As a result of lichenological exploration in Bitlis province (Turkey), a total of 325 lichens and 21 lichenicolous fungi, which are belonging 113 genera in Ascomycota were determined from 92 different localities. Buellia vouauxii, a lichenicolous fungus, and is new to Turkey and also new for Asia. Aspicilia glomerulans, Llimoniella muralicola, Myriolecis invadens, Ochrolechia subviridis, Placynthium hungaricum and Placynthium posterulum were reported for the second time from Turkey. Collecting localities and their substrata are presented.
A contribution to the lichen flora of Turkey is presented. A total of 282 lichen taxa and 20 lichenicolous fungi, of which 4 are varieties, are determined from 87 different localities in Muş province (Turkey). Lichenostigmagracile, a lichenicolous fungus, is new to Turkey, and 274 lichen species and 20 lichenicolous fungi are new for Muş.
There are many factors, which negatively affect plant development. One of these factors is lead (Pb), which causes toxic effects on plants during the seedling period. Mycorrhizas (AMF) contribute positively to plant growth. In eggplant seedlings, it has been researched whether to tolerate the negative effects of lead with mycorrhizas. In the study, Gigaspora margarita (Gm) and Glomus intraradices (Gi) mycorrhizal races were applied before seeds were sown. After the first true leaves appeared, 5 different doses of Pb (0, 100, 200, 400 and 800 ppm) were given. As a result, the earliest true leaf ...Daha fazlası
Agrobacterium-mediated transformation of upland rice is established in few numbers of cultivars due to the high cultivar-specificity of regeneration from transformed explants. Further, dehalogenase E (dehE) gene had been characterized in Pseudomonas putida and it produces an enzyme that degrades dalapon. This study aimed to transform Turkish upland rice with the dehE herbicide resistant gene and addresses the challenges of transgenic rice recovery by identifying explant and transformation method. Constructed vector pCAMdehE carrying dehE gene was transferred into the rice shoot apex by Agrobac ...Daha fazlası
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) ...Daha fazlası
This research was carried out in 2018 in order to determine the hay yields, forage qualities botanical compositions and range conditions of 5 different natural rangelands located at different altitudes the Chuy Region, Kyrgyzstan. In the rangelands, the ratio of plant coverage was 96.0-98.0%, the ratio of grasses, legumes, other plant families in the plant covered area was 24.5-48.1%, 4.7-24.0%, 36.2-63.8%, respectively. In the rangelands, the rate of decreaser, increaser and invader species was 37.0%, 7.3% and 55.7%, respectively. The average dry matter yield (DMY) of all five ranges was 2904 ...Daha fazlası
Halogenated organic compounds are extensively and widely used as pesticides, herbicides, and antibiotics that contribute to the pollution. This research was aimed to further analyze and characterize a bacterium that has the ability to utilize 2,2-dichloropropionic acid (2,2-DCP) as a model to study dehalogenase enzyme production. Microscopic observation, biochemical tests and PCR technique were carried out in order to characterize the isolated bacterium. Strain MF2 showed its ability to grow on 10 mM 2,2-DCP liquid minimal medium with doubling time of 13 h with maximum chloride ion released of ...Daha fazlası
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 ...Daha fazlası
This work aims to determine the response of Hypogymnia physodes (L.) Nyl. (hooded tube lichen) collected in an unpolluted site (Yenice Forest in Karabiik, Turkey) to stress conditions. In the present study, the effect of exposure to different heavy metals (Cd 2, Pb 2, and Cr 6) for different durations and UV radiations dosages on lichen was examined at the physiological and molecular levels. The effects of stress conditions were determined in the case of different parameters concerning heavy metal, protein, chlorophyll, and carotenoid contents and changes in the DNA profiles. According to the ...Daha fazlası
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. ...Daha fazlası
