  1. 4. engineering dhqase ( arod ) - deficient e. coli mutant with a second copy of the arob gene gene targeting technique was used to disrupt the arod gene in e. coli chromosome. the mutant 31bk was engineered, in which homologous recombination of the arobkanr gene cassette into the arod locus ( arod : : arobkanr ) of the e. coli strain atcc31884 genome utilized the helper plasmid pkd46 with red system. the host cell 31bk lacked catalytic activity of dhqase ( arod ) and had a second copy of the arob gene, so it improved carbon flow into the quinic acid biosynthesis direction

    構建宿主菌基因精確定位突變株31bk （ arod : : arobkan ~ r ）為了改變代謝途徑脫氫奎尼酸（ dhq ）分支點上的代謝流量，使之充分流向目的產物奎尼酸合成方向，利用基因打靶技術構建了31884宿主菌arod基因精確定位插入突變體，使dhq脫水酶（ dhqase ）失活，阻斷了碳代謝流流向芳香氨基酸生成的方向，同時用同源重組的方法將arob基因定位整合入染色體上，解除了限速酶對碳代謝流通過共同途徑到達dhq的阻遏影響，並減輕代謝負擔。
  2. The bvdv nadl strain is cytopathogenic. searching fromgenbank several cp strains " sequence of e2 gene about deer - n21, sh9, newyork - i and so on were found. according to the homologous sequence they were designed and synthesised a pair of primers by the biology software primer 5 and added bal i and nco i site to the 5 " end which can be used for the application of e2 gene and subcloning

    從genbank中搜尋出deer - n _ （ 21 ） 、 sh9 、 newyork -等cp型毒株的e _ 2基因序列，根據其同源性用生物學軟體primer5設計引物，並在引物的兩端加入bal和nco兩個酶切位點，酶切位點的存在易於對e _ 2基因進行克隆操作。
  3. Meanwhile, these six coat protein genes were sequenced and compared with other homologous sequences in genbank. the strain designation of the six isolates of tumv was finally determined. the results are as the following : 1. six isolates of turnip mosaic virus named tumv - sd1, tumv - sd2, tumv - sd3, tumv - sd4, tumv - sd5 and tumv - sd6 were respectively acquired from infected chinese cabbages and radishes in 3 cities ( taian, yantai and zaozhuang ) of shandong province

    利用rt - pcr方法克隆了tumv山東分離物的外殼蛋白（ cp ）基因，測定了它們的核苷酸序列、並將其與已報道的序列進行同源性比較和分析，最終確定了其歸屬地位，具體研究結果如下： 1 .從山東省3地市感病的白菜和蘿卜上分離到蕪菁花葉病毒的6個分離物，分別命名為tumv - sd1 、 tumv - sd2 、 tumv - sd3 、 tumv - sd4 、 tumv - sd5和tumv - sd6 。
  4. The homologous analysis showed that the n - terminal sequence of dhap is identical to that of serine protease from another b. pumilus strain tyo - 67 and has high homology with those from other bacillus species. based on the homologous analysis, three pairs of primers were designed and synthesized

    該序列與來自其它芽抱桿菌屬菌株的絲氨酸蛋白酶的n一末端氨基酸序列有較高的同源性，並和另一株短小芽抱桿菌的絲氨酸蛋白酶n一末端氨基酸序列完全一致。
