虽然DNA转座子经常产生内部缺失的衍生物，如微型反向重复转座元件，但由非长末端重复反转录转座子衍生的短内部缺失元件（SIDE）却很少。在这里，我们发现了一个新的SIDE，命名为Persaeus，它起源于鸡重复序列1（CR1）反转录转座子Zenon，并已被发现广泛存在于鳞翅目昆虫中。我们的研究结果表明，Persaeus和合作伙伴Zenon在其宿主基因组中经历了转座爆发，并且Persaeus和Zenon在测定的基因组中的拷贝数显着相关。因此，活性通过年龄分析表明，复制波的Persaeus与泽农。系统发育分析表明，珀尔萨可能已经独立进化了至少四次，并且已经垂直转移到其宿主基因组中。总之，我们的研究结果为SIDE及其合作伙伴非LTR的演变动态提供了新的见解。
Abstract Although DNA transposons often generated internal deleted derivatives such as miniature inverted-repeat transposable elements, short internally deleted elements (SIDEs) derived from nonlong terminal-repeat retrotransposons are rare. Here, we found a novel SIDE, named Persaeus, that originated from the chicken repeat 1 (CR1) retrotransposon Zenon and it has been found widespread in Lepidoptera insects. Our findings suggested that Persaeus and the partner Zenon have experienced a transposition burst in their host genomes and the copy number of Persaeus and Zenon in assayed genomes are significantly correlated. Accordingly, the activity though age analysis indicated that the replication wave of Persaeus coincided with that of Zenon. Phylogenetic analyses suggested that Persaeus may have evolved at least four times independently, and that it has been vertically transferred into its host genomes. Together, our results provide new insights into the evolution dynamics of SIDEs and its partner non-LTRs.
