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][self-published source?]} Even without knowing the nature of the specific genes, the process can still be used.^[1]

In plants

By molecular separation of transposons, from a cell nucleus, the cloning is enabled for genes which contain the transposons.^{[2][self-published source?]}

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]
