RNA-silencing of viral genes is a promising and effective way of controlling viral infection in plants. An inverted repeat (IR) fragment of the ORSV coat protein gene, <i>cp</i>, was inserted into the pXGY1 vector to generate the silencing construct, pXGY1-ORSV, which was introduced into <i>Nicotiana benthamiana</i>
