Then, the plasmid was transformed into jm109. the full length pstvd cdna recombinant plasmid was further identified by restriction mapping analysis and the nucleotide sequence of cdna cloned in pmd 18 - t vector was analyzed with ab1 377 dna sequence. test showed that the cdna of this chinese pstvd isolate was the same as pstvd - kf - 6 mild " type " isolate which originated from naturally infected potatoes in field of cornell university potato breeding program
利用rt - pgr技術，設計一對引物，對田間採集的經鑒定含pstvd的陽性樣品進行全序列擴增，並將所得產物純化回收，連接到pmd18t - vector中，並轉化至大腸桿菌jm109中，挑選白斑進行雙酶切（ saci / ecorv ）鑒定證明插入片段為359bp大小，進行序列測定，所得克隆基因為pstvd全序列負鏈，大小為359bp 。 -
374 - nt sequence analysis between nt 47 - 420 and restriction enzyme ( re ) clevage site mapping of f gene between nt 34 - 1682 were used to compare the 18 isolates for genetic analysis. a phylogenic tree was constructed based on the 374 - nt - sequence data of eighteen isolates in the study and 37 ndv reference strains from genbank and published resources
通過dnastar軟體對f基因47 470nt間片段進行同源性分析比較並繪制了遺傳進化樹枝狀結構發生圖，結合334 1672nt間三種限制性內切酶（ re ： hinf ， bsto及rsa ）位點的分佈情況，確定了這些分離株的基因分類地位。 -
The recombi - nant plasmid pgex - hnadc3 was identified by dma sequencing and restriction enzyme mapping
