We have previously obtained transgenic rice plants (Oryza sativa L.) containing S8 gene which encodes the outer coat protein of the rice dwarf virus (RDV) by particle bombardment. In this study, it was confirmed that the S8 gene has been stably inherited and expressed in the selfed T1 and T2 progenies of the primary trangenic rice plant line T0-2. Virus resistance assays revealed that both T1 and T2 transgenic plants exhibited resistance to RDV infection, indicating stable transmission of the trait of resistance. This study is the first report about the Pathogen-derived resistance in rice dwarf virus, a member of phytoreovirus.
Keywords:Oryza sativa;rice dwarf virus;coat protein gene;virus resistance
