Dsmv is proved as the predominating virus - pathogen on aroid plants from zhejiang province and other regions in china. cdna of dsmv rna 3 " end partial sequence and subgenomic rna promoter region of cucumber mosaic virus ( cmv ) rna3 were used as probes for detection of dsmv and cmv respectively. total rna extracted from field samples were used for rna dot - hybridization
用侵染馬蹄蓮的dsmv3末端序列和黃瓜花葉病毒（ cmv ）的亞基因組啟動子區互補dna序列為標記探針，對自然感病的天南星科植物進行rna斑點雜交，並結合雙鏈rna分析、病毒提純和形態學觀察，對杭州等地16屬天南星科植物的81個樣品進行了病毒鑒定。 -
This time, using cdna of zmcdc5 as template, we amplify a sequence by means of pcr technology. and then, using restrict endoenzyme and ligase, we conjunct the 0. 8kb length dna sequence in a expression vector, pet - 30a. after induction, expression and purification, we obtained a 35. 4kda truncated fusing zmcdc5 protein which contains 267aa ( 647 to 914aa in zmcdc5 ). with the purified protein, we got its antibody and testified the antibody by means of western blotting and dot blotting
本實驗是以zmcdc5的cdna為模板，使用pcr獲得基因片段，再通過酶切連接，將得到的0 . 8kb的基因片段構建於pet - 30a表達載體上，經過誘導表達和純化，獲得zmcdc5的融合蛋白，其中包括了zmcdc5925個氨基酸中647 914共267個氨基酸殘基 -
One was cloning, sequence analysis and expression of the fragment containing the b and c antigenic sites locating at the 5 " terminus in spike gene of tgev in prokaryotic expression system ( fused with gst ), the other was preparation of non - radioactive probe labeled by digoxigenin for detecting the rna extracted from tgev by assay of dot - blot
為了鑒別診斷tgev與prcv及對tgev進行流行病學調查，本研究採用原核表達系統（ gst融合表達系統）表達tgev纖突蛋白（ s蛋白）中含有b和c抗原位點的多肽，並且制備了非放射性地高辛標記的核酸探針，通過斑點雜交（ dot - blot ）檢測tgev核酸rna 。 -
Was multiplied and the tk gene was cloned. the cloned tk gene was retrieved by proper restrictive hemodynamics. the retrieved tk gene was labeled by digoxin according to the kit of labeling and detection of digoxin. then, the specificity and sensitivity of tk gene probe were detected with dot blot hybridization. the sequence of tk gene of nm98a strain was analysed. the result of the analysis of tk gene ' s sequence confirmed that autoploidy between tk gene of nm - 98a strain and issued strain was 99. 7 %
本研究中首次對iltv - nm98a株的tk基因進行了克隆和序列分析，結果表明： iltv - nm98a株tk基因的核苷酸序列與已發表的iltvtk基因的核苷酸序列具有高度的同源性，兩者之間僅相差4個核苷酸，同源性高達99 . 7 ，從而證實了iltvtk基因是高度保守的，為iltvtk基因核酸探針的制備提供了有力的依據。 -
Acetylornithine deacetylase is the key enzyme of producting l - methionine. we mainly do research work on the construction of acetylornithine deacetylase gene - engineering strain and characteristic of proteinase. in order to get high expression deacetylase strain, we obtain the gene by pcr arge gene. the product ( 2800bp ) was cloned into puc19 plasmid and confirmed with blue / white dot screening > restriction enzyme analysis and pcr. then taking the nucleotide sequencing compared with the sequence at blast of u. s. a. we constructed a high expression of gene - engineering strain - pxj 128 which containing the arge gene on the high expressing system of pxji18 with activity of acetylornithine deacetylase above 20000u / g
為了獲得高效表達的脫乙酰鳥氨酸酶工程菌株，在工程菌技術改造及其固定化研究做了進一步的研究和探討。我們採用基因工程技術，通過pcr技術擴增出了酰化酶關鍵酶基因?脫乙酰鳥氨酸酶基因arge ，將其克隆到puc19載體中，經酶切鑒定、 pcr鑒定篩選出重組陽性質粒，並測序鑒定，通過美國blast程序進行了基因數據庫相似性比較分析。
