Abstract
Rice black-streaked dwarf virus (RBSDV), a member of genus Fijivirus in the family Reoviridae, infects rice, maize, barley and wheat, and can seriously affect crop yields. RBSDV is transmitted by the small brown planthopper (Laodelphax striatellus, SBPH) in a persistent manner. RBSDV has 10 linear dsRNA genomic segments, making it difficult to construct infectious clones for functional studies in plants. Here we describe a method for inoculating and maintaining RBSDV on rice in a greenhouse for use in laboratory research. The protocol uses SBPHs mass reared in the laboratory. We also describe in detail the propagation of a healthy planthopper population, the preparation of plant material, RBSDV inoculation and the evaluation of the rice after inoculation.

Background
Rice black-streaked dwarf virus (RBSDV), a recognized member of the second group within the genus Fijivirus, family Reoviridae, seriously affects the production of rice and maize in East Asia (Shikata and Kitagawa, 1977; Zhang et al., 2001a). RBSDV is propagatively transmitted to rice, maize, barley and wheat by the small brown planthopper (Laodelphax striatellus, SBPH) in a persistent manner (Shikata and Kitagawa, 1977). SBPH can acquire RBSDV from fresh or frozen infected rice leaves and transmit it to healthy plants (Shikata and Kitagawa, 1977; Li et al., 2010). Once SBPH has acquired the virus, the virus can multiply in the insect vector and can be transmitted to host plants throughout the life of the insect. However, SBPH cannot transmit the virus transovarially (Boccardo and Milne, 1984). RBSDV has icosahedral, double-layered particles about 70-75 nm in diameter and 10 linear genomic segments of double-stranded RNA (dsRNA), ranging in size from approximately 1.8 to 4.5 kb (Marzachi et al., 1995; Zhang et al., 2001b). Our previous studies have shown the complexity of the interaction between RBSDV and host plants (Sun et al., 2015; He et al., 2017). Unfortunately, the numerous genomic segments make it difficult to construct infectious cDNA clones for reverse genetics studies. To facilitate the investigation of the interaction between RBSDV and its host plants, we describe a simple and efficient method for maintaining RBSDV infection in a greenhouse, including the propagation of the healthy planthopper population, preparation of rice plants, RBSDV inoculations and finally the evaluation of the rice disease symptom after inoculation.
