The total rna was purified from the germ in the liquid by the guanidine isothiocyantehod method , then the total rna digested by dnase that had not rnase was used for rt - pcr . i change the magnesium ion dencity in the pcr system in order to optimize the pcr condition . at the end i selected the magnesium ion density as 1 . 25 mm . the production of rt - pcr was inserted directionally into pgem ? z ( ampr ) . the pgem ? z ( ampr ) was used to transform e coli jm109 . i got a positive clone through culling and identificatin . the dna sequence inserted into pgem ? z ( ampr ) was sequenced and blasted with the cdna sequence of the # - mannanase mature peptide that got from genbank 分取誘導培養液中的菌體，用異硫氰酸胍法提取總rna ，總rna再經無rna酶的dna酶處理后用于rt ? pcr 。在pcr擴增目的基因時，通過優選擴增體系，使鎂離子濃度為1 . 25mm時rt ? pcr可順利地獲得目的基因，并能定向克隆到載體pgem ? 3z ( amp ~ r )中。用克隆載體轉化宿主大腸桿菌jm109 ，通過篩選獲取陽性克隆子，對陽性克隆子進行酶切與pcr鑒定，并對載體中插入的目的基因進行測序。 |

The results indicated that the synthetic mviia was reduced and oxidized in a buffer containing acetamide / guanidine hydrochloride by air oxidization in the room temperature and obtained a relatively well oxidization result , the synthetic mviia showed 100 % of physiological activity of native mviia , but obtained 1 % product of synthetic crude peptide 結果表明，合成的mviia在乙酸胺/鹽酸胍緩沖體系，室溫下采用空氣氧化法時獲得了較好的復性結果，合成復性的mviia幾乎具有天然mviia的100的生物學活性，但產率只有1左右。 |

The total rna was isolated from pokeweed ( phytolacca americana ) leaves using the method of guanidine isothiocyante and used as template to amplify the total length and deleted mutant pokeweed antiviral protein ( pap ) gene by rt - pcr and then the pap gene was cloned into pgem - t vector . the sequencing results showed that pap gene had 99 . 9 % identity comparing with the pap gene nucleotide sequence reported by lin et al ( 1991 ) . the iptg - inducible expression vector containing the pap gene was constructed and transferred into e . coli bl21 ( de3 ) - plyss 將缺失型pap基因克隆到植物表達載體pbi121中，通過液氮冷凍法將重組質粒轉入農桿菌lba4404細胞中，然后采用葉盤法，在該農桿菌的介導下將pap基因導入普通煙草中，經過卡那霉素抗性篩選，最后獲得了轉pap基因的工程煙草植株，摩擦接種煙草花葉病毒( tmv ) ，與非轉基因煙草相比，能夠推遲癥狀表現達2月之久，說明pap基因能夠在其它植物體內產生有活性的高抗病毒的蛋白質。 |
