Figure 2

Schematic representation of the structure of the PIF transposon family. Elements are named according to their length and are drawn to scale. Only one element from each subfamily is shown. PIF5.2 is previously described as PIF-6 and PIF2.3 is 98% identical to PIF-12 (16). Black triangles represent TIRs. Green and red rectangles represent the terminal sequences conserved in all elements (see text). Open rectangle indicates the fact that the internal region of PIF5.2 was not sequenced. Dark blue, pink, brown, light green, purple, and light blue rectangles represent internal regions unique to each subfamily. Yellow rectangle represents the internal region of mPIF.
