A PCR screening approach was used to search for sequences homologous to a previously described hAT transposon found in Drosophila simulans and Drosophila sechellia, named here as hosimary. In this study, 52 Drosophilidae species were analyzed and these sequences seem to be restricted to some species of the melanogaster group and Zaprionus indianus. These species present variable number of copies and most of those appear to be putatively encoding. The high hosimary sequences similarity among different species and the patchy distribution presented by this transposon strongly support the hypothesis that hosimary was horizontally transferred between the melanogaster group species and Z. indianus.
采用 PCR 筛选方法，搜索与先前在果蝇 simulans 和果蝇 sechellia 中发现的 hAT 转座子同源的序列，在此将其命名为 hosimary。在这项研究中，分析了 52 种果蝇科物种，这些序列似乎仅限于某些黑腹果蝇组和 Zaprionus indianus 物种。这些物种具有不同数量的拷贝，其中大多数似乎是假定的编码序列。hosimary 在不同物种之间具有高度的序列相似性，并且该转座子呈现出斑驳的分布，这强烈支持了 hosimary 是在黑腹果蝇组物种和 Z. indianus 之间水平转移的假说。
