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.

The results showed that Non-haemagglutinating activity was showed in the isolate. In agar diffusion test,there was a clear precipitin band formation to anti-IBDV specific serum. 28-day-old chicks inoculated with the isolate showed disease,and the isolate was recovered from the tissues of these chickens. The 1 041bp specific fragment were amplified by RT-PCR with sequence-specific primers based on IBDV VP3 gene. The VP3 gene shared 97.7%~98.2% nucleotide identities to very virulent IBDV,97.7%~95.2% nucleotide identities with classical strains from seqiemce analysis.

In order to clone the VIP gene in the gastrointestinal tract from beijing duck, one pair of specific primers to VIP gene was designed and synthesized according to the chick sequence (X80906). Encoding VIP cDNA fragments were amplified by RT-PCR from the total RNA in the Proventriculus, the Duodenum and the Jejunum of Beijing duck. Their PCR products were ligated into pGEM-T easy vector, which was transformed into E. coil JM109. Positive bacteria clones were screened and identified by PCR method and digested with the double restriction enzyme EcoRⅠ. The sequence of VIP gene fragment was also determined and analyzed.
