查询词典 transposon

The DNA sequences around the transposon inserted site were also amplified by inverse PCR and sequenced. Multisequence alignments showed that the mutated genes were highly similar to the malonyl coenzyme A transacylaseg gene, lipopeptide synthetase B gene and sensor histidine kinase gene, respectively.

反向PCR克隆转座插入位点周边序列及测序结果表明，转座突变的基因与编码脂肽类化合物合成和调控相关的malonyl coenzyme A transacylase、lipopeptide synthetase B和sensor histidine kinase蛋白基因具有高度同源性。

To obtain more information of magnesium homeostasis in mitochondria, mTn-lacZ/LEU2 transposon library was transformed into mrs2 deletion mutant to screen for suppressor genes of MRS2. YMR166C, a member of mitochondrial carrier family, was identified as a suppressor gene of MRS2. Deletion of YMR166C gene can rescue the defects of mrs2 deletion mutant such as the decrease in mitochondrial magnesium concentration, Group II RNA splicing defect and growth defect on nonfermentable carbon source. For the first time we demonstrated YMR166C is involved in mitochondrial magnesium homeostasis.

为了增进对线粒体镁离子代谢调控基因的了解，利用酿酒酵母mTn-lacZ/LEU2转座子文库筛选MRS2的抑制基因，发现线粒体载体家族成员YMR166C基因的缺失可以挽救MRS2基因缺失的突变体的生长缺陷、II型内含子剪接缺陷，并可以调节线粒体镁离子浓度，首次发现YMR166C是线粒体镁代谢相关基因。

Methods Seventy-four strains of Salmonella enterica serovar enteritidis (S. enteritidis), S. pullorum and S, gallinarum isolated from chickens were determined for biofilm using crystal violet staining, and the strain C050041 with well biofilm formation was chosen to construct a mutant library using transposon mutagenesis.

利用结晶紫染色定量法对74株鸡源的肠炎、鸡白痢和鸡伤寒沙门氏菌进行生物膜测定，选择生物膜生长较好的肠炎沙门氏菌C050041，采用转座子随机插入法构建突变株库。

Different types of Rim2 elements constitute a super transposon family in rice genome that can be transcriptionally activated by the infection with rice blast pathogen Magnaporthe grisea. This study focuses on the structure and distribution of elements of transposasecoding subgroup of this superfamily.

以基因组克隆Rim2-569为代表，分析了该家族中转座酶编码亚组的分子结构，同时对Rim2因子在染色体和不同水稻品种之间的差别分布情况进行了研究。

A transposon mutagenesis system applicable for Xanthomonas campestrispv.campestrishas been developed by transferring the transposonTn5gusA5,which contains the gus reporter gene,to the broad host rangvector pLAFR1 and taking the advantage of incompatibility between pLAFR1and pPH1JI plasmids.Five different types of exopolysaccharidedeficient mutants related respectively to eight different mutated sites wereisolated by applying the system to mutagenize the Xcc wild type strain.

本研究将含gus报告基因的转座子Tn5gusA5转座到广谱宿主载体质粒pLAFR1后，利用pLAFR1与pPH1JI质粒的不相容性，建立了一套适合于甘蓝黑腐病菌的转座子诱变体系，应用该体系诱变甘蓝黑腐病菌野生型菌株，成功地分离到5种不同类型、分别涉及8个不同突变位点的胞外多糖突变体。

Retrotransponson is one of the major parts of rice transposon.

逆转座子是水稻转座因子的一个主要组成部分。

One particular transposon first appeared about a million years ago.

一次特殊的转位最早出现在大约一百万年前。

One particular transposon first appeared about a million years ago.

大约在100万年前第一次出现了特殊的转位子。

A transposon system was also used to prolong the insulin expression in the liver.

实验还采用了转座元系统来延长肝脏中胰岛素的表达。

More than 20,000 lines of rice mutant were obtained through transposon and T-DNA tagged strategies.

利用转座子和T-DNA 标签技术，获得了超过20，000 株系的水稻突变群体；对其中5000 多个株

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
