  1. Analysis of the sequence variation of cytochrome b gene indicated that there is no evidence of insertions or deletions, i. e., they are all of identical length of 1143 bp in all the sequences of cytochrome b gene. further, the sequences can be fully translated into amino acid using chicken mitochondrial codon without nonsense mutations or intervening stop codons. the 1143 bp cytochrome b alignment contained 416 variable sites, of which 306 were parsimony informative sites with the strongest variable in third codon positions and less variable in first and second codon positions

    細胞色素b基因序列變異分析表明： 1 ）雁形目鳥類細胞色素b基因全序列長度一致，無插入和缺失：對照雞線粒體密碼子系統全序列能全部翻譯成氨基酸序列，無無義突變，全序列內部無終止密碼子； 2 ）序列比對后1143加，含416個核著酸變異位點， 306個簡約信息位點，其中處於密碼子第三位的變異最大，第一位和第二位堿基的變異相對較小。
  2. The mutant lines were crossed with deficiency lines on chromosome 2 and 3 respectively, and the genetic sites of 11 stocks have been determined. of them four showed a different phenotype from the known genes that control the heart development

    分別將這些有心臟突變的品系與果蠅第二和第三染色體缺失系雜交，測定了11個品系的遺傳學位點，其中4個品系在遺傳學位點上有別于已經報道的心臟發育控制基因。
  3. Therefore, blys, its receptor or related antagonists may find medical utility in the treatment of b cell disorders associated with autoimmunity, neoplasia, or immunodeficiency syndromes. in this study, epo signal peptide sequence and hsblys gene were linked by soe method. the fusion product was cloned into eukaryotic plasmids. pcdna3, pcdna3. 1, pefneo, respectively. meanwhile, the epo signal peptide sequence was mutated so as to form a restriction enzyme cut site : bin i. thus the recombinant plasmid can be used as secreting plasmid expressing other gene

    本實驗通過3 』端互補，進行引物延伸合成epo信號肽序列：信號肽和hsblys基因採用重疊延伸拼接法形成融合基因；融合基因分別插入pcdna3 . 0 、 pcdna3 . 1 、 pefneo真核載體：引物延伸合成信號肽時，利用亮氨酸同義密碼，將信號肽基因的倒數第二個密碼突變，在重組載體上的信號肽序列之後，形成bln酶切位點，使三種載體成為分泌表達載體。
  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 orf1 protein of senv - h12 - 1 isolate was consisted of 675 amino acids and 92 amino - terminal amino acids less than senv - h ( ax025838 ), it had insertion in two sites also. the orf1 protein of senv - h 12 - 2 isolate was 7 amino acids less than senv - h ( ax025838 ) because of deletion. because the first start code was mutated, the orf2 protein of senv - h 12 - 2 isolate started from the second atg code, so that it was 7 amino acids less than senv - h ( ax025838 ) from its n - terminus

    兩個senv - h亞型分離株的情況與已發表的博士學位論文: sen病毒分子病毒學和流行病學研究對sen琴h （ ax025838 ）株分析的結果有所不同: senv - h12一1分離株的orfi僅由675個氨基酸組成，比senv - h （ axo25838 ）的orfi少n一末端的92個氨基酸，此外在2個位點上還存在插入: senv - h12一2分離株在一些位點上的缺失造成o盯1蛋白比senv - h （ axo25838 ）少7個氨基酸，由於第一個起始密碼子發生突變，採用位於下游的第二個起始密碼子使得o即2蛋白比senv - - h （ axo25838 ）少n一末端的7個氨基酸。
