Pokeweed antiviral protein belongs to Ribosome-inactive Proteins. PAP has potent antiviral activity against many plant virus. pT1 was used as the template to amplify the deleted mutant PAP gene (N-deleted and N-,C-deIeted) by PCR and then the two genes were cloned into expression vector. Different IPTG-inducible expression vector containing different deleted mutant PAP gene was constructed and transferred into E.coli strain BL21 (DE3)-plysS.

美洲商陆抗病毒蛋白是一类能很好的抑制植物病毒的蛋白，很早就有报道低剂量的商陆叶片粗粉末就能明显的抑制TMV在菜豆叶片上局部枯斑的形成，PAP缓释剂也已用于病毒病的防治工作，但美洲商陆抗病毒蛋白属于核糖体失活蛋白，它对生长的细胞会有一定的毒性。

The total RNA was isolated from pokeweed leaves using the method of guanidine isothiocyante and used as template for amplification of the deleted mutant pokeweed antiviral protein gene by RT-PCR and then the amplified fragment was cloned into secreted expression pPIC9K vector to form pPIC9K-p, then the vector was transferred into Pachia pastoris GS115 strain.

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.
