在秀丽隐杆线虫中发现了一个与毛里求斯果蝇（Drosophila mauritiana）的marinine基因（EMBL登录号X77804）具有高度同源性的重复序列。该元件在秀丽隐杆线虫的N2株中以约20个拷贝存在，并且在相关株BO和杂交株RW 7097和TR 679中以大致相等的拷贝数出现。在Caenorhabditis的三个相关物种中只有一个MLE副本。这个水手样元件（MLE）的cDNA编码的蛋白质与果蝇转座酶有58%的同源性。类水手元素在N2中是不移动的。这类元素现已在昆虫、真涡虫和线虫中描述（GenBank登录号M98552和本报告）。
A repetitive element inC.eleganshas been found that bears high homology to the elementmarinerofDrosophila mauritiana(EMBL accession number X77804). This element is present in about 20 copies in the N2 strain ofC.elegans, and appears in roughly equal copy numbers in the related strain BO and in the hybrid strains RW7097 and TR679. There is only one copy of this MLE in three related species ofCaenorhabditis. A cDNA of thismariner-like element (MLE) codes for a protein with 58% homology to theDrosophilatransposase. Themariner-like element is not mobile in N2. This class of elements has now been described in insects, planaria and nematodes (GenBank accession number M98552 and this report).
