Vector construction for transformation of tobacco with a NAC-type transcription factor, TaNAC69-1

Eroğlu, Ayten
Yucel, Meral
NAC type transcription factors are a large family of plant transcription factors related to defense, development, biotic and abiotic responses of plants. To construct vectors for tobacco transformation, traditional and Gateway cloning technology were used. For traditional cloning, firstly TaNAC69-1 gene was isolated from Triticum aestivum L. cv. Yuregir-89. After cDNA synthesis, TaNAC69-1 gene was cloned into pJET1.2 cloning vector. To transfer the gene into dicot expression vector, pORE-E3, both pJET1.2 and pORE-E3 vector were cut with ClaI and NotI enzymes forming sticky ends on both vectors. TaNAC69-1 gene was bound to pORE-E3 vector carrying same sticky ends like the gene. T4 DNA ligase was used for ligation of TaNAC69-1 gene into the vector. After transferring obtained vector into empty Escherichia coli DH5α strain, positive colonies growing on LB media including kanamycin were selected and colony PCR was performed. pORE-E3 vector carrying TaNAC69-1 gene was transferred to Agrobacterium tumefaciens EHA 105 strain via electroporation. For Gateway cloning, pENTR™/D-TOPO cloning vector and pEarleyGate 100 expression vector were used. After isolation, TaNAC69-1 gene was amplified using wheat cDNA samples and cloned into pENTR™/D-TOPO cloning vector. After cloning into entry vector, TaNAC69-1 gene was transferred into Gateway compatible binary destination vector, pEarleyGate 100, through LR reaction. A. tumefaciens EHA105 strain was transformed with destination vector via electroporation. To check the insertion of TaNAC69-1 gene, colony PCR was performed using gene specific primers.


Targeted disruption of homoserine dehydrogenase gene and its effect on cephamycin C production in Streptomyces clavuligerus
Yilmaz, Ebru I.; Caydasi, Ayse K.; Özcengiz, Gülay (Springer Science and Business Media LLC, 2008-01-01)
The aspartate pathway of Streptomyces clavuligerus is an important primary metabolic pathway which provides substrates for beta-lactam synthesis. In this study, the hom gene which encodes homoserine dehydrogenase was cloned from the cephamycin C producer S. clavuligerus NRRL 3585 and characterized. The fully sequenced open reading frame encodes 433 amino acids with a deduced M (r) of 44.9 kDa. The gene was heterologously expressed in the auxotroph mutant Escherichia coli CGSC 5075 and the recombinant protei...
Overexpression of serine alkaline protease encoding gene in Bacillus species: performance analyses
Çalık, Pınar; Ozdamar, TH (Elsevier BV, 2003-12-02)
Bacillus species carrying subC gene encoding serine alkaline protease (SAP) enzyme were developed in order to increase the yield and selectivity in the bioprocess for SAP production. For this aim, subC gene was cloned into pHV1431 Escherichia coli-Bacillus shuttle vector, and transferred into nine host Bacillus species, i.e. B. alvei, B. amyloliquefaciens, B. badius, B. cereus, B. coagulans, B. firmus, B. licheniformis, B. sphaericus and B. subtilis. The influence of the host Bacillus species on SAP product...
Analysis of acyl CoA ester intermediates of the mevalonate pathway in Saccharomyces cerevisiae.
Şeker, Tamay; Nielsen, J (Springer Science and Business Media LLC, 2005-04-01)
The mevalonate pathway plays an important role in providing the cell with a number of essential precursors for the synthesis of biomass constituents. With respect to their chemical structure, the metabolites of this pathway can be divided into two groups: acyl esters [acetoacetyl CoA, acetyl CoA, hydroxymethylglutaryl (HMG) CoA] and phosphorylated metabolites (isopentenyl pyrophosphate, dimethylallyl pyrophosphate, geranyl pyrophosphate, farnesyl pyrophosphate). In this study, we developed a method for the ...

Survival kinetics of lactic acid starter cultures were modeled considering the microorganism and external medium interfacial area as the critical factors determining the resistance of the microorganisms to freeze-drying. Surviving fraction of the microorganisms increased with the increasing biomass concentration during freeze-drying, and this is attributed to the mutual shielding effect of the microorganisms against the severe conditions of the external medium. Survival of the microorganisms over the storag...
Expression of chitinase A (chiA) gene from a local isolate of Serratia marcescens in Coleoptera-specific Bacillus thuringiensis
Okay, S.; Tefon, B. E.; ÖZKAN, MELEK; Özcengiz, Gülay (Wiley, 2008-01-01)
Aims: The present study focused on cloning and expression of chiA gene from a highly chitinolytic local isolate of Serratia marcescens in an anti-Coleopteran Bacillus thuringiensis and comparison of the characteristics of the native and recombinant ChiAs.
