We have identified a novel extrachromosomal viral-element (PEVE) in the asexual strain of planarian G. tigrina . PEVE is the first viral element identified in planaria, and comprises two potential helicases that are homologous to proteins from distant viral phyla.
Examination of PEVE in Spanish asexual planaria
Genomic DNA and total RNA from asexual planaria of the Spanish population were supplied by Dr. Salo E. (University of Barcelona).
Several DNA sequences similar to the mariner element have been reported in G. tigrina [ 10 16 ] . There are about 7000 copies of this element in the genome, which appear to code for an active transposase [ 10 ] . None of these mariner elements are present in the genomes of other turbellarians, including the species closest to G. tigrina [ 10 ] . With the aid of PCR using specific primers for the planarian mariner element, we isolated and sequenced several clones from sexual and asexual planaria.
Unlike asexual animals, mature planaria of the sexual strain possess well-distinguished reproductive organs and lay fertile cocoons.
