Zinc (Zn) is an essential micronutrient for the growth and development of all organisms. Zinc deficiency is a widespread micronutrient disorder worldwide, which reduces crop yields and the nutritive value of the grain. Understanding the process of zinc absorption and translocation in crop is essential for this purpose. Zinc is taken up by plants and translocated within plants through high-affinity zinc transporter proteins embedded in the plasma membrane. The Zn transporters are induced under Zn deficiency, and it is speculated that the expression levels of some of zinc transporters are critical for improved tolerance to low zinc. A number of Zn transporters have been cloned from higher plants including rice and Arabidopsis, but little has been done in barley and wheat. This project aims to investigate genes involveld in zinc efficiency mechanism by complementation analysis in yeast, which is double mutant of zinc-transporters, using cDNA expression library from a most zinc efficient barley cultivar, Tokak-157.

Effect of boron and iron stress on phytosiderophore production in barley
İnce, Yetkin Çaka; Yücel, Ayşe Meral; Department of Biology (2015)
Boron and iron are essential nutrients for growth and development of higher plants. Deficiency and toxicity of them cause significant changes in physiological, cellular and molecular make-up of plants. Iron uptake in barley is mainly achieved by production and release of phytosiderophores to the environment. On the other hand, production of phytosiderophores are affected by concentrations of boron and iron. Four enzymes which function in phytosiderophore hydroxymugineic acid (HMA) production namely NAS, NAA...
Peroxidation of membrane lipids in minimally processed cucumbers packaged under modified atmospheres
Karakaş, Barçın; Yıldız, Fatih; Department of Food Engineering (2002)
Peroxidation of membrane lipids is an inherent feature of ripening and senescence of plant tissues. Increased lipid peroxidation has also been observed in the development of chilling injury in susceptible tissues. In this study, the effect of storage conditions and physical tissue damage on membrane peroxidation of minimally processed cucumber (Cucumis sativus, L.) was investigated. Model modified atmospheres were achieved passively by storage of the minimally processed cucumbers at 4°C and 20°C in hermetic...
Cloning and heterologous expression of the extracellular alpha-galactosidase from Aspergillus fumigatus in Aspergillus sojae under the control of gpdA promoter
Gurkok, Suemeyra; Soyler, Betuel; Biely, Peter; Ögel, Zümrüt Begüm (Elsevier BV, 2010-07-01)
Aspergillus fumigatus is highly pathogenic especially for immunocompromised people however it can efficiently produce many industrially important enzymes. The gene coding et-galactosidase enzyme (aglB) of A. fumigatus IMI 385708 has been cloned onto pAN52-4 fungal expression vector and expressed in a GRAS organism, Aspergillus sojae ATCC11906 under the control of constitutive glyceraldehyde-3-phosphate dehydrogenase (gpdA) promoter. pAN52-4 fungal expression system allowed high level alpha-galactosidase pro...
Kinetic analysis of aspergillus oryzae cultivations on starch
Bayındırlı, Alev; UNGAN, S (Informa UK Limited, 1991-01-01)
Cultivation of Aspergillus oryzae on starch is described as a combination of two rate processes: Starch hydrolysis and the cellular activities of the fungi including growth, enzyme production and maintenance. Kinetic models are presented to describe growth, enzyme production, starch hydrolysis and uptake of the hydrolysis products. Numerical values of the model parameters indicated that the rate controlling step of A. oryzae growth on starch was not starch hydrolysis, but the substrate uptake process. Gluco...
Analyses of extracellular protein production in Bacillus subtilis - II: Responses of reaction network to oxygen transfer at transcriptional level
KOCABAŞ, PINAR; ÇALIK GARCİA, GÜZİDE; Çalık, Pınar; Ozdamar, Tuncer H. (Elsevier BV, 2017-11-15)
Oxygen transfer influences intracellular fluxes which are orchestrated by genome and its transcription in Bacillus subtilis throughout fermentation in recombinant human growth hormone (rhGH) production. Responses of B. subtilis reaction network to oxygen transfer were analysed at transcriptional level with determined transcriptome and calculated intracellular fluxes by the reconstructed genome scale model iBsu1144(rhGH) based on updated gene-enzyme-reaction data. iBsu1144(rhGH) employing 1067 reactions link...
