Abstract

Unlike peoples’ belief that transposable elements (TEs) are “junk DNAs” or “genomic parasites”, TEs are essential genomic elements that bring about genetic diversity and enable evolution of a species. In fact, transposons are major constituent of chromosome in crop genomes, particularly in major cereal crops, the primary type of which is long terminal repeat (LTR) retrotransposon. Since TE mobilization can be controlled by specific environmental stimulation and as the result can generate novel genetic variations, it has been suggested that controlled mobilization of TEs can be a plausible method for crop breeding. To achieve this goal, series of sequencing techniques have been recently established to identify TEs that are active in mobility. These methods target and detect extrachromosomal DNAs (ecDNAs), which are final products of integration. The newly identified TEs by these methods exhibit strong transpositional activity which can generate novel genetic diversity and provide useful breeding resources.
