The term "transposon tagging" refers to a process in genetic engineering 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. Even without knowing the nature of the specific genes, the process can still be used.
Transposon tagging in plants
By using transposon tagging, researchers have been able to add genetic elements from maize (corn) and Antirrhinum into some other species (such as tobacco, aspen and others). 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.
