Progress in plant CACTA elements.
Transposable elements are DNA fragments that can insert new chromosomal locations. On the basis of the mechanism of transposition, transposable elements were divided into two classes. Class 1 elements were retroelements that used reverse transposase to transpose by an RNA intermediate. Class 2 elements or DNA transposons transposed directly from DNA to DNA. Of the Class 2 elements, CACTA superfamily, so far identified exclusively in plants and previously regarded as low-copy-transposon for the conserved mechanism of propagation, recently received considerable interest because of their increasing evidence reiterating their high copies in some plant genomes. This article aimed at outlining CACTA elements with regard to their structure, transposition, and utilization.
