Utility of the pat gene as a selectable marker gene in production of transgenic Dunaliella salina
Background: The objective of this study was to develop an efficient selectable marker for transgenic Dunaliella salina. Results: Tests of the sensitivity of D. salina to the antibiotic chloramphenicol and the herbicide Basta® showed that cells (1.0 × 10 cells/ml) treated with 1000 or 1500 μg/ml chloramphenicol died in 8 or 6 days, respectively, whereas D. salina cells (1.0 × 10 cells/ml) treate...

Characterization of the Hansenula polymorpha PUR7 gene and its use as selectable marker for targeted chromosomal integration.
The Hansenula polymorpha genes encoding the putative functional homologs of the enzymes involved in the seventh and eighth step in purine biosynthesis, HpPUR7 and HpPUR8, were cloned and sequenced. An overexpression vector designated pHIPA4 was constructed, which contains the HpPUR7 gene as selectable marker and allows expression of genes of interest via the strong, inducible alcohol oxidase pr...
متن کاملRecombineering with tolC as a Selectable/Counter-selectable Marker: remodeling the rRNA Operons of Escherichia coli
This work describes the novel use of tolC as a selectable/counter-selectable marker for the facile modification of DNA in Escherichia coli. Expression of TolC (an outer membrane protein) confers relative resistance to toxic small molecules, while its absence renders the cell tolerant to colicin E1. These features, coupled with the lambdaredgam recombination system, allow for selection of tolC i...
متن کاملCloning and molecular characterization of TaERF6, a gene encoding a bread wheat ethylene response factor
Ethylene response factor proteins are important for regulating gene expression under different stresses. Different isoforms for ERF have previously isolated from bread wheat (Triticum aestivum L.) and related genera and called from TaERF1 to TaERF5. We isolated, cloned and molecular characterized a novel one based on TdERF1, an isoform in durum wheat (Tri...
