Transgenic tobacco plants were obtained through screening with kanamycin. The transgenic tobacco plants could delay TMV infection for about 25 days compared with non-transgenic tobacco plants. Pokeweed antiviral protein Ⅱ is expressed with high level in summer leaves. The expression of PAPⅡ is regulated by season. The total RNA was extracted from pokeweed (Phytolacca americana L.) leaves in summer using the method of TRIzol and used as template to amplify the PAPⅡ gene by RT-PCR and then the gene was cloned into E. coli expression vector and secreted expression pPIC9K vector. The two vectors with PAPⅡ gene were then transferred into E. coli strain BL21 (DE3)-plysS and Pachia pastoris GS115 strain respectively. The specific protein was produced induced by IPTG and methanol.

由于美洲商陆抗病毒蛋白Ⅱ是一个受季节调控表达的蛋白，本实验以美洲商陆夏季叶片为材料，通过对其总RNA的提取、反转录、并用PAPⅡ的特异引物进行PCR扩增，对PAPⅡ进行了基因克隆、序列分析，结果扩增出来的PAPⅡ基因与已经报道的序列同源性是99.9％，然后将该基因构建到原核、真核表达载体上，分别转化了大肠杆菌和毕赤酵母并对它们进行了诱导表达，在两个表达系统中均获得了有活性的PAPⅡ表达蛋白，体外生物测定表明表达的蛋白均具有抑制病毒的活性，PAPⅡ基因在酵母中还没有表达的报道，这为获得具活性PAPⅡ蛋白提供了一种简便可行的方法。
