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。Fanned by a constant updraught of ventilation between the kitchen and the chimneyflue, ignition was communicated from the faggots of precombustible fuel to polyhedral masses of bituminous coal, containing in compressed mineral form the foliated fossilised decidua of primeval forests which had in turn derived their vegetative existence from the sun, primal source of heat radiant, transmitted through omnipresent luminiferous diathermanous ether
