marker gene

A variant allele used to label a biological structure or process throughout an experiment. Marker genes are located in a constant genomic position in a particular organism.

marker gene

a gene whose location and characteristics are well-known and which is used to investigate other genes; for example, to determine the location of any gene relative to the marker gene.

Deciphering diversity and ecological function from marine metagenomes

Some plant species, most notably grasses, are more amenable to transformation by particle bombardment, which generally involves cotransformation of two separate plasmids or DNA molecules, one for the gene of interest and one for the marker gene.

We have used transgenic techniques to produce animals bearing a gene for the collagen [alpha]1(IV) chain containing a single point mutation at the proposed CBS in combination with marker genes rol-6 (su1006) and Green fluorescent Protein (GFP).

The transfer of marker genes to target cells depends on the function of the envelope protein; therefore, the titer of neutralizing antibodies against the envelope can be measured by a reduction in marker gene transfer.

The approval of this marker gene was a regulatory blunder committed in the United States and elsewhere, as it is clear that kanamycin is still widely in clinical use, and the marker gene confers resistance to new generation aminoglycosides as well (6).
