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.

The purpose of this study is to screen microorganisms with growth inhibition against plant fungal pathogens. The plate-dilution method was used to isolate the bacteria from salt marshes at Dafeng, Jiangsu. The antifungal activity of the bacterial broth filtrates against 5 phytopathogens was determined using mycelial disk method. The antifungal compositions of four active bacteria were analyzed primarily with chromatography techniques. Two hundred and thirty-five aerobic (92) and anaerobic (143) bacterial strains have been isolated from the coast salt marsh and sixty-five strains, of which 39 are aerobic and 26 are anaerobic showed greater than 30% of inhibition rate against the growth of at least one of the phytopathogenic fungi on petri dish.

The inhibition effect of chloroform fraction was the most potent, with the inhibition rate about more than 83% to 5 plant pathogenic fungi under the concentration of 15mg/mL. Under the concentration of 15mg/mL, the ethyl acetate fraction and n-butanol fraction thoroughly inhibited the growth of Alternaria solani and Valsa mali, with the inhibition rate up to 100%. The n-butanol fraction showed the highest potent virulence, with EC50 to Alternaria solani and Valsa mali about 0.09 and 0.279 mg/mL respectively.
