Abstract EN
Mutator-like transposable elements (MULEs) are widespread in plants and the majority have long terminal inverted repeats (TIRs), which distinguish them from other DNA transposons.
It is known that the long TIRs of Mutator elements harbor transposase binding sites and promoters for transcription, indicating that the TIR sequence is critical for transposition and for expression of sequences between the TIRs.
Here, we report the presence of MULEs with multiple TIRs mostly located in tandem.
These elements are detected in the genomes of maize, tomato, rice, and Arabidopsis.
Some of these elements are present in multiple copies, suggesting their mobility.
For those elements that have amplified, sequence conservation was observed for both of the tandem TIRs.
For one MULE family carrying a gene fragment, the elements with tandem TIRs are more prevalent than their counterparts with a single TIR.
The successful amplification of this particular MULE demonstrates that MULEs with tandem TIRs are functional in both transposition and duplication of gene sequences.
