The rate of repetitive sequences was 2.55% and no SINEs, LINEs, LTR anti-transcription elements or DNA transposon elements were found, although one11 microsatellite was found. 2 In the P1 promotor region, sequence homology between the Tibetan sheep and mouflon, goat, cattle and European bison was 99.7%, 94.2%, 85.9% and 86.5%, respectively, while that for exon 1A was 99.0%, 97.0%, 92.7% and 94.6%, respectively. 3 The molecular phylogenetic tree among these species, constructed by the neighborhood joining method based on the sequences of no-coding region of the GHR genes, placed the two Bovinae species on one branch and the three Caprinae species on the other.

在该非编码序列中，重复序列所占比率为2.55%，不存在SINEs、LINEs、LTR类反转录元件和DNA转座子元件，而发现存在一11微卫星位点；(2)在启动子P1区，藏绵羊与摩弗伦羊、山羊、普通牛、欧洲野牛各物种间同源性大小分别为99.7%、94.2%、85.9%、86.5%；而在外显子1A区段，藏绵羊与摩弗伦羊、山羊、普通牛、欧洲野牛各物种间同源性大小分别为 99.0%、97.0%、92.7%、94.6%。

We show that these germline infiltrations likely occurred around the same evolutionary time (15–46 mya) and spawned some of the largest bursts of DNA transposon activity ever recorded in any species lineage (nearly 100,000SPINcopies per haploid genome in tenrec).

这组科学家在调查夜间活动的灵长类动物——丛猴的DNA转座子的时候发现了这些成分，在经过进一步检查之后，他们在其他物种中也发现了这些"侵略者"，包括大鼠和小鼠、负鼠和非洲爪蛙。

The National Institute of Agrobiological Sciences in Tsukuba, Japan, has accumulated numerous rice biological resources and has already successfully produced a high-quality genome sequence, a high-density genetic map with 3000 markers, 30 000 full-length cDNAs, oer 700 expression profiles with a 9000 cDNA microarray and 15 000 flanking sequences with Tos17 insertions in about 3765 mutant lines from about 50 000 transposon insertion lines.

日本的NIAS（National Institute of Agrobiological Sciences ）已经积累了大量的水稻生物学资源，并成功完成水稻全基因组的测序工作，构建了3000个marks的高密度遗传图谱，收集了30000条全长cDNA序列、超过含有9000cDNA条cDNA microarray的700个表达谱，和Tos17插入大约50000个转座子插入系中的3765个突变系的15000条侧翼序列。

Fans saw the seller used a leaf, ready to be an impeller to the pedestal, the transposon leaves connection with the plug socket on the dock, in any event could not get tired bromidrosis a gas or not he sing sing to "咔嚓,咔嚓" twice cut the plug and socket, four head directly to the end of two hastily beat.

只见卖主拿来一个风扇叶，准备将叶轮安到座上，将叶子的插销与座子连线上的插座对接时，无论如何都插不进去，累了一头臭汗还是不成他便气哼哼地&咔嚓、咔嚓&两声把插头插座剪掉，直接将四个线头打两个结草草了事。

These properties produce robust systems that limit the catastrophic consequences of transposon mobilization, which can result in the accumulation of deleterious mutations, changes in gene expression patterns, and conditions such as gonadal hypotrophy and sterility.

这些属性特征构成了一个限制由转座元件活动所造成的严重后果的系统，从而防止转座子侵袭所带来的突变积累，基因表达谱的改变，以及生殖腺发育不良和不育。

In this study we build a Mycobacterium marinum random mutant libratory with MycoMarT7 transposon phage, found two cell wall virulence genes with colony morphology and cording structure strategy and build up virulence detection system in cell and animal model. We concluded that PDIM is critical for the virulence of Mycobacterium marinum.

本课题利用MycoMarT7噬菌体建立了海分枝杆菌随机突变库，以海分枝杆菌为模型筛选出两个分枝杆菌细胞壁毒力相关基因，并建立了海分枝杆菌的毒力检测系统，发现PDIM在海分枝杆菌的致病性中起到重要重要的作用。

Then we transformed mTn-lacZ/LEU2 transposon library into the YES2MTM1 strain. Transformants lost the plasmid overexpressing MTM1 after 5-Fluoroorotic acid treatment. We picked up the yeast strains able to grow on nonfermentable carbon source with MTM1 deletion and some transposon insertion and identified the insertion sites.

因MTM1基因的缺失造成的损伤不可逆，直接转入文库无法筛选得到MTM1 基因缺失表型相关基因，本研究利用外源MTM1基因菌株和mTn-lacZ/LEU2酿酒酵母转座子文库进行筛选，寻找能挽救mtm1突变体生长缺陷的转座子插入位点。
