Development of a negative selectable marker for Entamoeba histolytica.
Entamoeba histolytica is the causative agent of amebiasis and infects up to 10% of the world's population. The molecular techniques that have enabled the up- and down-regulation of gene expression rely on the transfection of stably maintained plasmids. While these have increased our understanding of Entamoeba virulence factors, the capacity to integrate exogenous DNA into genome, which would al...
متن کاملA bacterial haloalkane dehalogenase gene as a negative selectable marker in Arabidopsis.
The dhlA gene of Xanthobacter autotrophicus GJ10 encodes a dehalogenase which hydrolyzes dihalo- alkanes, such as 1, 2-dichloroethane (DCE), to a halogenated alcohol and an inorganic halide (Janssen et al. 1994, Annu. Rev. Microbiol. 48, 163-191). In Xanthobacter, these alcohols are further catabolized by alcohol and aldehyde dehydrogenase activities, and by the product of the dhlB gene to a se...
متن کاملThymidine kinase as a negative selectable marker in Leishmania major.
We have tested whether the thymidine kinase gene of herpes simplex virus 1 (HSV-1 tk) could function as a negative selectable marker in Leishmania major. Several drug resistance markers have been used for positive selection of transfected DNA in trypanosomatids, including neomycin phosphotransferase (NEO; refs. 1-4) and hygromycin phosphotransferase (HYG; refs. 5,6). Negative selectable markers...
متن کاملSelectable Marker Gene Removal and Expression of Transgene by Inducible Promoter Containing FFDD Cis-Acting elements in Transgenic plants
Abstract Background: Selectable marker gene (SMG) systems are critical for generation of transgenic crops. Transgenic crop production Background: Selectable marker gene (SMG) systems are critical for generation of transgenic crops. Transgenic crop production without using SMG is not economically feasible. However, SMGs are non-essential once an intact transgenic plant has been established. Eli...
متن کاملSelectable marker genes in transgenic plants: applications, alternatives and biosafety.
Approximately fifty marker genes used for transgenic and transplastomic plant research or crop development have been assessed for efficiency, biosafety, scientific applications and commercialization. Selectable marker genes can be divided into several categories depending on whether they confer positive or negative selection and whether selection is conditional or non-conditional on the presenc...
