Transposon tagging

In genetic engineering, transposon tagging is a process where transposons (transposable elements) are amplified inside a biological cell by a tagging technique. Transposon tagging has been used with several species to isolate genes.[1] Even without knowing the nature of the specific genes, the process can still be used.[1]

Transposon tagging in plants

By molecular separation of transposons, from a cell nucleus, the cloning is enabled for genes which contain the transposons.[2]

By using transposon tagging, researchers have been able to add genetic elements from maize (corn)[3] and Antirrhinum into some other species (such as tobacco,[4] aspen[5] and others).[2] A gene responsible for a particular phenotype can be cloned within a given species, when movement is accompanied by the presence of a mutant phenotype.[2]
