研究了蚂蚁Messor bouvieri、M. barbarus和M.在先前的论文中研究的结构体在三个物种中被组织为串联重复的79-bp单体，显示出高度的序列相似性。本论文将一个mariner-like元件（Mboumar）和一个新的MITE（miniature inverted-repeat transposable element）IRE-130插入到M. bouvieri，进行了分析。对Mboumar元件、其转录和其编码的假定转座酶的研究表明，它可能是一个活性元件。还检测到插入IRE-130元件中的Mboumar元件。据我们所知，这是第一次在Hyattera中描述了MITE，也是第一次检测到插入MITE的水手样元素。一个类似水手的元件，插入到M.结果表明，转座事件参与了卫星DNA的迁移和进化。(c)2006 Elsevier B.

The satellite DNA of ants Messor bouvieri, M. barbarus and M. structor, studied in a previous paper, is organized as tandemly repeated 79-bp monomers in the three species showing high sequence similarity. In the present paper, a mariner-like element (Mboumar) and a new MITE (miniature inverted-repeat transposable element) called IRE-130, inserted into satellite DNA from M. bouvieri, are analyzed. The study of Mboumar element, of its transcription and the putative transposase that it would encode, suggests that it could be an active element. Mboumar elements inserted into IRE-130 elements have also been detected. It is the first time, to our knowledge, that a MITE has been described in Hymenoptera and it is also the first time that a mariner-like element inserted into a MITE has been detected. A mariner-like element, inserted into satellite DNA from M. structor and in M barbarus, also has been found. The results seem to indicate that transposition events have participated in the satellite DNA mobilization and evolution. (c) 2006 Elsevier B.V. All rights reserved.
