However, it is little reported that SINEs were investigated in crprinidae. Currently, SINEs from cyprinidae have almost exclusively concerned on the zebrafish, with almost nothing reported about SINEs in other crprinid species, especially SINEs studies for cyprinidae phylogeny.

本研究基于这些问题，开展了鲤科鱼类中SINEs的研究工作，并得到如下结果：1在A-B PCR方法的基础上，以鲤科鱼类中的马口鱼为对象，利用反向PCR方法，建立了分离SINEs的简便方法。

Here, we have pioneered the SINEs study in cyprinidae family based on the above questions, the results following:1 In this study, we firstly apply the inverse PCR protocol for isolating the SINEs from Opsariichthys bidens genome on the basis of A-B PCR.

马口鱼的基因组DNA利用HaeIII酶切后，利用T4连接酶进行自环化；环化后的DNA分子在反向引物的引导下执行反向PCR，最后，一组衍生于tRNA的SINEs从马口鱼基因组内获得，并根据马口鱼的学名Opsariichthy bidens命名为Opsar。

It achieves 90-97% accuracy in the classification of novel DNA and LTR repeats, and 75% for LINEs and SINEs.

在对新的DNA和LTR重复进行分类时，获得了90-97%的准确率，对LINEs和SINEs进行分类时，获得了75%的准确率。

The rate is 11.85% for SINEs,6.44% for MIRs and 1.22% for LINEs respectively.

LINEs所占比率小于SINEs元件，为1.22％。

SINEs insertion can be stably delivered to descendants, thereby, SINEs can provide the reliable evolutionary information, and used as molecular markers for phylogeny events within 50Mys, such as the levels of family and order.Cyprinidae, the largest fish family, comprises approximately 210 recognized genera and 2010 species.

鲤科鱼类是世界上现生鱼类中最大的一个科，约有210属2010个种，但有关鲤科鱼类中SINEs的研究却很少，目前相关的报道仅限于斑马鱼基因组内；而有关利用SINEs插入位点信息进行鲤科鱼类系统进化的研究更没有报道。

The SINEs RNA were transcripted by polymerase III; the transcripts can be reversely transcribed and the DNA products inserted into the host genome. The insertion of a SINE can be asseumed to be unidirectional since there is no known mechanism to precisely remove SINEs after their fixation of the host genome.

SINEs插入基因组后，很难在其相同位点精确的去除，能相对稳定地遗传；因此为系统进化分析提供了良好的分子标记，并被认为在物种50Mys的进化事件上能提供比较可信的进化信息，尤其是在科属以下的物种中。

Short interspersed elements are widespread among eukaryotic genomes and are moderately repetitive DNA sequences. These molecules range from 70-500bp in length. There are usually 103-105 copies of a SINEs family in a eukaryotic genome. The evidences suggested that SINEs have proliferated by retrotransposition.

短散在核重复序列(short interspersed elements SINEs)是广泛分布于真核生物基因组内的中度重复序列，分子长度在70-500bp，在基因组内的拷贝数为103-105；SINEs在基因组内以返转座的方式进行增殖，由RNA聚合酶III转录成RNA，再反转录成cDNA插入到基因组内。

In the interspersed repeats (SINEs, LINEs, LTR elements, DNA elements), SINEs and LINEs occur most frequently, LTR elements occur less and DNA elements occur the least frequently.

在散布重复序列中，短散布重复序列和长散布重复序列出现的最多；长末端重复序列出现的较少，而DNA elements出现的最少。散布重复序列在大鼠和小鼠内含子中分别占插入序列总长度的33%和35%；散布重复序列在大鼠和小鼠内含子中分别占缺失序列总长度的18%和15%。
