- Example Sentences:
| 1. | The rest mutations in pp38 and pp24 are at random . sequence analysis also shows the first 195 nuclear acids of pp38 and pp24 are the same except for the 81 site ( g / c ) , but this mutation does not cause the change of amino acid . we regard this as a genetic marker connecting with geography in the evolution of mdv but not related to isolated time and pathotype of different strain of mdv i
对pp24基因和pp38基因进行同源性比较分析的结果表明，绝大多数毒株二者的前195个核苷酸完全一致，不同毒株间的第81位核苷酸的差异( g / c )并不引起编码的氨基酸变化，仅仅与地域分布有关，这很可能是mdv在长期病毒衍化过程中形成的地域性遗传标志，而与病毒的分离年代及mdv的致病型等因素无关。 | | 2. | The comparison of meq gene sequences of different pathotypes of marek ' s disease virus meq genes of different pathotypes of marek ' s disease virus ( mdv ) were amplified , in the whole opening reading frame ( orf ) by polymerase chain reaction ( pcr ) technique , sequenced and compared with the published sequence of ga strain ( representing vmdv ) . cvi988 / rispens and 814 , commercial vaccine strains popularly used worldwide and in china respectively ; 648a , representing very virulent plus ( vv + mdv ) and 6 field isolates , originated from guangxi commercial chickens with visceral lymphomas and vaccine breaks , representing high pathogenic ( hpmdv ) and two of them ( g2 and n ) were proved to be vvmdv , were used
本研究通过三个方面进行了研究，取得了如下主要实验结果： 1mdv不同致病型( pathotypes )毒株meq基因序列的比较研究应用pcr技术扩增了不同致病型mdvs ，即国际通用型疫苗毒cv1988 rispens株和中国特有的疫苗毒814株、特超强毒648a株( vv + mdv )以及6个广西分离到的野毒株共9个毒株的meq基因，进行核苷酸序列的测定并与标准强毒ga株( vmdv )进行核苷酸和氨基酸序列的比较。 | | 3. | The comparative analysis of sequences indicated that the sequences of meq in different pathotypes are relatively conserved and the homology of the amino acid sequences is very high . the significant differences include two mutations in both mdv - 1 vaccine strains cvi988 / rispens and 814 strain : the deletion of a proline ( no . l93aa ) , and this mutation is just exactly located in a 15 - amino - acid ( eelcaqlcstppppi ) repeat sequence within the c - terminal transactivation domain of meq protein ; and a point mutation with a shift from alanine ( a ) of all virulent strains to serine ( s ) was occurred on the no . 71 aa
结果发现， mdv不同致病型的meq基因序列相对比较保守，它们相互间核苷酸和氨基酸序列的同源性均很高；但是，与所有七个致瘤性的mdv毒株相比，二个型弱毒疫苗cv1988 rispens株和814株均出现了两个特征性的突变：即第194位的p缺失性突变和第71位氨基酸由a变成了s的位点突变；缺失性突变恰恰位于meq基因中转录激活域内的一个多脯氨酸的重复序列( pppp )之中。 |
