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。The advantages of hcci are numerous comparing with the traditional engine. relative to si gasoline engines, hcci engines are more efficient, because they have no elimination of throttling losses, use the high compression ratios and have shorter combustion duration. relative to cidi engines, hcci engines have extraordinarily lower emissions of pm and nox and can offer more power as high as cidi engines with the dilute homogeneous air and fuel mixture
與傳統的發動機相比均質壓燃（ hcci ）具有很多優勢:與火花點火汽油機相比， hcci發動機由於沒有節流損失，壓縮比較高，燃燒持續期短，其效率更高;與直噴柴油機相比， hcci發動機的碳煙和氮氧化物排放非常低，並且稀薄空燃混合氣可以產生與柴油機一樣高的功率。
