Mutator-Like Elements with Multiple Long Terminal Inverted Repeats in Plants

Figure 1

The structure of distinct types of MULEs with additional TIRs in tomato including their copy numbers and the number of TIR families involved in formation. Black horizontal arrows indicate target site duplication (TSD); solid colored triangles indicate Terminal Inverted Repeat (TIR); colored boxes indicate internal sequence and are labeled accordingly if sequences are annotated as genes or have similarity to MULE transposases.
