查询词典 homology

Homology of sequences can be of two types:'''orthology''' or '''paralogy'''.

同源序列可分为两种：直系同源和旁系同源。

Results indicate that the number of bacteria grown in media LB, CSEA and WSA was 14.84×10^7, 10.27×10^7 and 6.91×10^7 CFU per gram dry soil, respectively, after 192 h of incubation. The diversity index of soil bacteria was the highest in WSA, while the lowest in LB. Certain similarity was discovered in bacteria community between the three media, i. e. the Jaccard index was 57.69% between LB and CSEA, 53.13% between LB and WSA and 66.67% between CSEA and WSA. Phylogenetic analysis suggests that the dominant bacterial groups in the soil belong to β-Proteobacteria,γ-Proteobacteria and Actinobacteria. The sequence of 16S rDNA of some OTUs was found to have high homology with Burkholderiaceae bacterium, Rhodococcus and Mycobacterium, so it is presumed that the cells of these bacteria can secrete Resuscitation-Promoting Factors, which may effectively improve culturability of soil microorganisms.

结果表明，LB、CSEA、WSA培养基192h后每g干土获得的细菌数量分别为14.84×10^7、10.27×10^7和6.91×10^7CFU，但微生物多样性指数以WSA为最高，LB多样性指数最低；三种培养基培养的细菌菌群有一定的相似性，LB和CSEA培养基间的Jaccard指数为57.69%，LB和WSA培养基之间为53.13%，而CSEA和WSA培养基的相似性指数达66.67%；16SrDNA测序结果表明，所获得的土壤细菌优势种群在分类方面主要属于γ-和β-变形杆菌以及放线菌亚门，其中某些OTUs中的16SrDNA序列与Burkholderiaceae bacterium、Rhodococcus和Mycobacterium属具有较高的同源性，推测其细胞能够分泌复苏促进因子，有效地提高土壤细菌的可培养性。

The results showed that the 16S rDNA copies of Bacteroides spp. decreased in rotavirus-infected children by 2 orders of magnitudes. 665 clones in Group H and 284 clones in Group R were sequenced and 34 OTUs were obtained according to 98% sequence homology. Partial least squares discriminant analysis of the clone library profiling data revealed significant structural shifts of gut microbiota.

利用偏最小二乘判别法(Partial least squares discriminant analysis，PLS-DA)对这34个OTU进行分析，结果表明轮状病毒感染导致肠道内拟杆菌组成结构发生了变化，通过拟杆菌的组成可以将健康个体与轮状病毒感染个体分开，而对于区分两组个体起关键作用的OTU分别与Bacteroides vulgatus ，Bacteroides stercoris和Bacteroides fragilis有很高的同源性。

Two of the six clones had the same DNA sequence,so there are five different antigenic epitopes in the six clones;the Blast analysis showed that there were no sequence homology between the five epitopes and the known antigen of paragonimus.

上述6个克隆有2个克隆的DNA序列完全相同，即6个克隆包含了5种不同的抗原表位；Blast分析表明5个表位与已知的肺吸虫抗原表位无DNA序列的同源性。

The results of sequencing was contrasted by BLAST software. The sequence of the PCR products shared 100% homology with Pasteurella multocida reference strain.

设计1对引物进行PCR扩增、克隆之后，送往大连宝生物公司测序，测序结果运用BLAST软件比对，与多杀性巴氏杆菌同源性为100%。

Analysis of the secondary structure of ITS1 in Pectinidae: implications for phylogenetic reconstruction and structural evolution It is at present difficult to accurately position gaps in sequence alignment and to determine substructural homology in structure alignment when reconstructing phylogenies based on highly divergent sequences.

4栉孔扇贝与扇贝科其它7种扇贝ITS1二级结构的系统进化与结构进化分析目前，在序列比对过程中对缺口进行精确定位十分困难。

There was no identical proteins in the database we searched, but it shared high sequence homology with PNZIP from Pharbitis nil and two other open reading frames of unknown function from Synechocystis spp and Porphyra purpurea. These together defined a new family of evolutionarily conserved leucine zipper proteins, which might play a role as a transcription factor in the regulation of gene expression.

GenBank数据库搜寻结果显示，AT103未与任何已知功能基因有同源性，但与裂叶牵牛PNZIP、集胞藻的一个ORF、紫菜的一个ORF，构成了一个在进化上非常保守的含有亮氨酸拉链结构域的新家族，极有可能是一新的核基因转录因子。

The results showed that the gene and amino acid sequence homology between seven species are over 44.3% and 47.90/o, respectively. In addition, conservation of three sequences: EQCGSQAGGALCP, CCSQFOWCGST and CQSQC in the 40 amino acids sequence at the beginning of the N-terminal chitinase mature protein is very high, The conservation of eight Cys at the sites of 3,12,17,18,24,31,36,40 is 100% Finally, the chitinase signal peptide gene from Phaseolus vu?

结果表明七种基因之间有44.3％以上的同源性，蛋白之间有47.9％以上的同源性，而且在成熟蛋白N端前40个氨基酸序列中分别位于1～13、17～27和36～40位的EQCGSQAGGALCP、CCSQFGWCGST和CQSQC序列区保守性很高，尤其是位于第3、12、17、18、24、31、36、40位的八个半胱氨酸的保守性达到100％。

Through the traditional physiological and biochemical method, together with the 16SrDNA sequence homology and phylogenetic analysis, the strains were identified. The result shows they belong to the genus photobacterium, but they differ from any species of this genus in some characteristic which suggests they might be new species, and their taxonomic placement needs more information on genes level.

对两株菌进行鉴定，分析其生理生化特征和16SrDNA产物序列，确定这两株菌均属于发光杆菌属，但是和该属的各种还有一定差异，对其分类地位的最后确定还需进一步的系统发育学分析。

The term deep homology was coined to describe the common origin of genetic regulatory apparatus used to build morphologically and phylogenetically disparate animal features.

&深同源&一词是造来描述遗传调控元件的共同起源，这些遗传调控元件是用来构建在形态上和系统发育上全异的动物特征。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
