Abstract

Virus inoculation is a basic experimental procedure to evaluate the resistance of a rice variety or a transgenic material upon virus infection. We recently demonstrated that Rice ragged stunt virus (RRSV), an oryzavirus that is transmitted by brown planthopper (BPH), can suppress jasmonic acid-mediated antiviral defense through the induction of microRNA319 and facilitate virus infection in rice. To verify this, we performed virus inoculation experiments on wild-type rice plants and miR319-TCP21-associated transgenic rice plants through a modified group inoculation method. Here, we presented the detailed procedure of RRSV propagation and infection process on rice plants.
