Transcription Of The Autographa Californicanuclear Polyhedrosis Virus P39 Gene In Bombyxmori Cell Culture, Zihni Demi̇rbağ
Turkish Journal of Biology
Transcription of the Autographa californica nuclear polynedrosis virüs (AcNPV; Family: Baculoviridae) p39 gene (delayed-early gene) has been studied extensively in the productive system of Spodoptera frugiperda cells. This is the first transcriptional study of this gene in the Bombyx mori cell line. In this study, comparative transcription of the AcNPV p39 gene was examined in S. frugiperda and B. mori cell cultures. Northern blot hybridization of totoal RNA samples, isolated from mock-infected (O and 48 hour post infection, h.p.i.) and AcNPV-infected (0, 2, 6, 12, 24, 48 h.p.i.) S. frugiperda and B. mori cell lines, was analyzed. Results indicates that …

The Construction Of A Mammalian Transfectionvector For Expression Of Cytosine-5 Specific Dnamethyltransferase Gene M.Msp1 In Cultured Cells, Öztürk Özdemi̇r
Turkish Journal of Biology
The expression vectors are designed for expression and purification of normal or recombi-nant gene of interest. There is a wide variety of stable and transferable selectable mammalian expres-sion vectors.The vector pCDM8 and its derivatives, pcDNAI/Ampicilline are widely used for cloning and analyzing of genes in higher eukaryotic cells. The vectors pRC/CMV, pcDNA3 and pRC/RSV are designed for high-level expression of recombinant genes in mammalian cells. In the present study, we have been able to transfect and express the monospecific bacterial (Moroxcella spp) cytosine-5 DNA methyltransferase (MTase) M.Msp1 gene in cultured cells within a newly con-structed mammalian transfection vector.

Biochemical Characterization Of Elastase Frompseudomonas Aeruginosa Ses 938-1, Semra Kocabiyik, Ezgi Ergi̇n
Biochemical Characterization Of Elastase Frompseudomonas Aeruginosa Ses 938-1, Semra Kocabiyik, Ezgi Ergi̇n
Turkish Journal of Biology
We have investigated some biochemical properties of elastase from a new strain o f Pseudomonas aeruginosa (SES 938-1). Activities were measured at 410 nm using N-succinyl-L-(ala) 3 -p- nitroanilide as substrate. The elastase activity followed Michaelis-Menten kinetics over the substrate range of 0.067-0.540 mM with the apparent K m value of 0.375 mM. Optimum activity was observed at 36 °C and pH 7.5. elastase activity was inhibited by metal chelating agents and high concentrations of Mn 2+ , Zn 2+ and Ni 2+ . The results obtained suggest that elastase from P. aeruginosa SES 938-1 is a neutral metalloproteinase.

Turkish Journal of Biology
Thirty six bean seed samples collected from bean fields in Eskisehir-Türkiye were examined for detection and isolation of Pseudomonas syringae pv. phaseolicola. A polyclonal antiserum specific to P. s. pv. phaseolicola NCPPB 52 was raised in a rabbit and both biochemical and serological test were used for identification. Heat-stable O antigens of 92 isolates identified as P. S. pv. phaseolicola together with authentic isolates of the bacterium were compared by Ouchterlony immunodiffusion test and all the isolates had a common antigenic structure.

Determination Of 5'-Nucleotidase Activity Of Higherplants By Using An Improved Method, Yusuf Turan
Determination Of 5'-Nucleotidase Activity Of Higherplants By Using An Improved Method, Yusuf Turan
Turkish Journal of Biology
The presence of relatively high non-specific phosphatase activities are known in various plant tissues. These enzymes also catalyze the removal of inorganic phosphate from nucleoside monophosphates. According to published reports, so far, the experimental investigations, concerning the 5'-nucleotidase activity, have been mostly carried out without consideration of the non-specific phosphatase activities in crude enzymic extracts. However, few researchers have been included some inhibitors of these phosphatases, such as NaMoO 4 or KF, in assay mixtures. But phosphatases are not completely inhibited by these inhibitors and, therefore, interfere the activity of 5'-nucleotidase. Thus, the non-specific phosphatase activities were determined in crude …

Purification And Characterization Of Pediocin F, Abacteriocin Produced By Pediococcus Acidilacticif, Özlem Osmanagaoğlu, Ufuk Gündüz, Yavuz Beyatli, Cumhur Çökmüş
Turkish Journal of Biology
In this work, Pediococcus acidilactici F isolated from fermented sausage was reported to produce an extracellular antimicrobial peptide, termed Pediocin F, that was protein in nature and effec-tive against many bacteria associated with food spoilage and food related health hazards. Pediocin F is reported here to be sensitive to proteolytic enzymes, resistant to heat and organic solvents, and active over a wide range of pH. We have also reported that the extracellular antimicrobial protein pro-duced by P. acidilactici F was really a small peptide. Coomassie-blue stained SDS-PAGE technique allowed us to estimate the molecular weight of this small peptide to …
A Theoretical Study On The Sex-Pheromones Of Therice Moth, Corcyra Cephalonica Stainton, Lemi Türker
A Theoretical Study On The Sex-Pheromones Of Therice Moth, Corcyra Cephalonica Stainton, Lemi Türker
Turkish Journal of Biology
Molecular orbital calculations (AM1 type) were performed on the geometry optimized structures of various farnesal isomers and methyl esters of farnesoic acids. It has been found that the major component, E, E-farnesal, of the sex-pheromone for the rice moth, Corcyra cephalonica Stainton is chemically the most exothermic and stable of all the farnesal isomers. Then, the resem-blance of molecular shapes was detrmined in order to design more stable sex-attractants.

Larval Growth And Survival Of Penaeus Indicus(Decapoda: Penaeidae) On Live Feeds, Metin Kumlu
Turkish Journal of Biology
This study was conducted to compare the suitability of three microalgal species (Tetraselmis chuii, Skeletonema costatum and Rhinomonas reticulata), both individually and in combination, as food for Penaeus indicus during larval culture. To determine the best feeding density, each alga was fed to protozoea 1 (PZI) larvae from 10 to 80 cells mL -1 . The best algal-cell density, promoting the highest survival rate, greatest growth and fastest larval development, was obtained at 60-70 cells mL -1 with a combination of T. chuii and S. costatum. Low cell densities (10-20 cells mL -1 ) were not effective. The diatom S. …

Turkish Journal of Agriculture and Forestry
According to the results obtained from two years rotation experiment, which was carried out under Ankara-Haymana dryfarming conditions during 1991-1993, conclusions can be summarized as follows: Soil water contents measured during vegetation period as well as at harvest time of six previous crops were significantly different in the first year of the rotation. At harvest time of previous crops and planting time of wheat, higher soil water content found in fallow plots in comparison to winter sown legumes (lentil, vetch, pea and Hungarian vetch). Oil radish and mustard as other previous crops, led to the lowest soil water content. In …
