The present study was carried out to examine the interaction of vanadium and phosphorus and changes in heat shock genes to optimize the growth of chickpea genotypes. Two sets of hydroponic experiments were carried out using vanadium and phosphorus with five-level central composite design. Five levels of vanadium (0-1180 mu M) and phosphorus (0-100011 mu M) were used to evaluate their interactive effects. Plants fresh biomass and uptake of vanadium and phosphorus were influenced by vanadium and phosphorus application. Enhanced fresh biomass was most likely a result of increased phosphorus uptake by chickpea genotypes. Addition of vanadium induced toxic effects while, higher concentration of phosphorus alleviated its toxic effects. The obtained results also indicated that lower vanadium concentration promoted phosphorus absorption however; higher concentration of vanadium inhibited the phosphorus uptake. The morphological changes in leaves indicated that the cells were deformed and reduced in size when treated with higher vanadium levels with fixed phosphorus while, there was little deformation and reduction in cells size were observed when plants were treated with higher levels of phosphorus with fixed vanadium. Whereas, the proportion of deformation of cells were higher in Balkasar as compared to C-44 genotype. The results also showed that at elevated vanadium with fixed phosphorus, Hsp70 was expressed only in C-44 while, not in Balkasar however, Hsp90 and GAPDH showed non-significant results.

Metabolic reaction network of Pichia pastoris with glycosylation reactions: Flux analysis for erythropoietin production Eskitoros, Melda S.; Ata, Ozge; Çalık, Pınar (Wiley, 2014-11-01) BACKGROUND: Biochemical reaction network of Pichia pastoris was improved by including N-glycosylation pathway reactions to determine the intracellular reaction rates for glycosylated protein production.
Comparison of antioxidant enzyme activities and DNA damage in chickpea (Cicer arietinum L.) genotypes exposed to vanadium Imtiaz, Muhammad; Mushtaq, Muhammad Adnan; Rizwan, Muhammad Shahid; Arif, Muhammad Saleem; Yousaf, Balal; Ashraf, Muhammad; Xiong Shuanglian, Xiong Shuanglian; Rizwan, Muhammad; Mehmood, Sajid; Tu, Shuxin (2016-10-01) The present study was done to elucidate the effects of vanadium (V) on photosynthetic pigments, membrane damage, antioxidant enzymes, protein, and deoxyribonucleic acid (DNA) integrity in the following chickpea genotypes: C-44 (tolerant) and Balkasar (sensitive). Changes in these parameters were strikingly dependent on levels of V, at 60 and 120 mg V L-1 induced DNA damage in Balkasar only, while photosynthetic pigments and protein were decreased from 15 to 120 mg V L-1 and membrane was also damaged. It was...
Comparison of benzaldehyde lyase production capacity in recombinant Escherichia coli and recombinant Bacillus species Kaya, Hande; Çalık, Pınar; Department of Chemical Engineering (2006) In this study, the benzaldehyde lyase (BAL, EC 4.1.2.38) production in E. coli BL21 (DE3) pLySs as intracellular and in Bacillus species as extracellular were investigated, and comparison of the production capacity of the enzyme in the developed recombinant microorganisms were compared. For this purpose, firstly, PCR amplified bal gene was cloned into pRSETA vector which is under the control of strong T7 promoter and expressed in E. coli BL21 (DE3) pLysS strain. With developed recombinant E. coli BL21 (DE3)...
GENETIC CONSEQUENCES OF LINKAGE BETWEEN MALATHION RESISTANCE AND AN AUTOSOMAL MALE-DETERMINING FACTOR IN HOUSE-FLY (DIPTERA, MUSCIDAE) KENCE, M; Kence, Aykut (1992-10-01) The pattern of inheritance of genes conferring resistance to malathion and genetic consequences of linkage between an autosomal male-determining factor and resistance genes on the second chromosome were investigated in a strain of house fly, Musca domestica L., selected for malathion resistance. The second and fifth chromosomes contribute significantly to malathion resistance. The presence of a male-determining factor linked with the resistance genes on the second chromosome resulted in a strong sexual dimo...
Dynamic flux balance analysis for pharmaceutical protein production by Pichia pastoris: Human growth hormone Çalık, Pınar; Taspinar, Hatice; Soyaslan, Elif S.; Inankur, Bahar (Elsevier BV, 2011-03-07) The influence of methanol feeding rate on intracellular reaction network of recombinant human growth hormone (rhGH) producing Pichia pastoris was investigated at three different specific growth rates, namely, 0.02 (MS-0.02), 0.03 (MS-0.03), and 0.04h(-1) (MS-0.04) where Period-I (33 <= t < 42 h) includes the early exponential growth phase; Period-II (42 <= t < 48 h) is the exponential growth phase where the specific cell growth rate decreases; Period-III (48 <= t <= 51 h) is the exponential growth phase whe...
