Abstract: The inhibition of plant activator protein on RNA and coat protein of tobacco mosaic virus (TMV) was studied. The concentration of TMV RNA in the tre
ated tobacco was reduced by 28%. Using ELISA and Western blotting assays, the concentration of TMV coat protein in the treated tobacco was reduced by 20.7% and 25.0% respectively. It was also revealed that the polymerization of TMV coat protein could be interfered distinctly by plant activator protein at 22-37℃ in vitro.
