We have shown that a strain-specific group I intron (intron 3) in the nuclear extrachromosomal rDNA or Physarum polycephalum is a mobile element. Shortly after mating of amoebae from intron-lacking and intron-containing strains, intron 3 transposes in a site-specific manner into all available recipient molecules. The transposition appears to occur by gene conversion, as evidence by the co-conversion of adjacent sequences and by double strand breakage observed in some of the recipient rDNA… CONTINUE READING
