SIRE-1 is a potential soybean retrovirus which has a gene order similar to Ty1-copia retrotransposons but also contains an envelope-like open reading frame (ORF), which is characteristic of retroviruses. PCR and Southern analysis reveals that SIRE-1 is closely related to a legume-wide family of envelope-lacking Ty1-copia group retrotransposons which suggests that SIRE-1 was formed by the recent acquisition of an envelope gene by a Ty1-copia retrotransposon.

Notes

The relationship between retroviruses and retrotransposons is one of the unsolved questions in biology. This work provides evidence that retroviruses may be formed by the acquisition of envelope genes by retrotransposons and therefore changes current opinion of the origins and evolution of retroviruses. SP performed every aspect of the work.
