The coat protein (CP) gene of rice

The coat protein (CP) gene of rice stripe viruswas introduced into two japonica varieties of rice by electroporationof protoplasts. The resultant transgenic plants expressedthe CP at hih levels (up to 0.5% of total solubleprotein) and exhibited a sinifcant level of resistance to virusinfection. Plants derived from seLfed progeny of the primarytransformants also expressed the CP and showed viral resistance,idicating stable transmission of the CP gene and thetrait of resistance to the next generation. Moreover, the virallyencoded stripe disease-specific protein was not d d intrbnsgenic plants expressing CP 8 weeks after oculation,indicating protection before viral multiplication. These studiesdemonstrated that CP-mediated resistance to virus infectioncan be extended to cereals and to the viruses transmitted by an insect vector (planthopper).
