To dissect the molecular mechanisms of plant viral interference, host genes were screened using the T-DNA tagged lines of Arabidopsis thaliana. Cucumber mosaic virus (CMV) vectors expressing fluorescent proteins were used for inoculation onto the A.thaliana lines All the A. thaliana lines examined in this study showed neither break down nor compromise of virus interference.We further examined the roles of the RDR1 and the IVR genes in virus resistances. The RDR1 gene showed inhibitory acts multiplication of Potato virus Y.However the RDR1 gene did not affect plant viral interference. Low temperature and plant viral synergism also did not compromise the interference. The results suggested that RNA silencing machinery does not contribute greatly to the phenomenon.
