  1. 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，然後採用葉盤法，在該農桿菌的介導下將pap基因導入普通煙草中，經過卡那黴素抗性篩選，最後獲得了轉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。
