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.
SIRE-1是一种潜在的大豆逆转录病毒,其基因顺序与Ty1-copia逆转座子相似,但也包含一个类似包膜的开放阅读框(ORF),这是逆转录病毒的特征。PCR和Southern分析表明,SIRE-1与豆科植物中缺乏包膜的Ty1-copia类逆转座子家族密切相关,这表明SIRE-1是由Ty1-copia逆转座子最近获得包膜基因而形成的。
