  1. The nucleotide ( nt ) sequence of the insert in phz1754 is 2299bps in size. computer assisted analysis of the sequence revealed an open reading frame ( orf ) with a g + c content of 70. 3 % that would encode a protein of 552 amino acids ( aa ). the nt seque nce comparision revealed that the orf in the sequenced region exhibits 85 % dna sequence homology with the cholesterol oxidase gene choa of streptomyces sp

    對phz1754進行外切核酸酶（ exonuclease ， exo ）順序缺失，獲得單向長度漸減重疊的系列突變體，核苷酸序列測定顯示出該ecor - sal片段的精確大小為2299bps ， frameplot程序分析揭示出該區域一個完整的開放閱讀框（ orf ）的存在，其大小為1656bps ， g + c含量為70 . 3 ，編碼552個氨基酸，利用blastsearch程序將orf的核苷酸序列及推導的氨基酸序列與因特網上基因及蛋白質數據庫進行綜合比較，發現無論在核苷酸水平還是在蛋白水平上，該orf均與膽固醇氧化酶表現出同源性，而且與鏈黴菌膽固醇氧化酶同源性最高，說明該orf編碼膽固醇氧化酶基因。
  2. There were deletion, insertion or mutation within the ibv isolates, the frontal 150nt showed the high variation

    核苷酸序列前150bp的變異最大，不同毒株間存在插入、缺失及點突變等。
  3. Beth showed 56 % identity to the opud of bacillus subtilis and belonged to bcct family. its putative promoter region was highly homologous to b - dependent promoter of b. subtilis. a 2. 6 kb fragment including the beth gene was subcloned into puc18 and transformed into the e. coli mkh13, colonies appeared on the plate of the selective m9 medium

    將包括整個beth基因orf框及可能的啟動子核苷酸序列在內的2 . 6kb的片段克隆到puc18載體上，轉入到大腸桿菌甘氨酸甜菜堿缺失株mkh13中，使該菌株能夠在含甘氨酸甜菜堿的高鹽m9培養基上生長，而對照實驗不能生長。
  4. 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

    結果發現， mdv不同致病型的meq基因序列相對比較保守，它們相互間核苷酸和氨基酸序列的同源性均很高；但是，與所有七個致瘤性的mdv毒株相比，二個型弱毒疫苗cv1988 rispens株和814株均出現了兩個特徵性的突變：即第194位的p缺失性突變和第71位氨基酸由a變成了s的位點突變；缺失性突變恰恰位於meq基因中轉錄激活域內的一個多脯氨酸的重復序列（ pppp ）之中。
  5. The results showed : ( 1 ) in the d - loop of mtdna genome from 18 individuals, there were only transition and transversion, were not insertion and deletion, and the frequency of transition was higher than transversion ; ( 2 ) and nucleotide diversity was 0. 0011, the sequence divergence values among haplotypes was 0. 005

    研究結果顯示： （ 1 ） 18隻大鴇的301bp - 330bpmtdna控制區序列的突變只有轉換和顛換，無插入和缺失，且轉換的頻率高於顛換； （ 2 ）核苷酸多態性只有0 . 0011 ，不同單元型間的序列差異值為0 . 5 。
