Rice Ragged Stunt Virus

Southern rice black-streaked dwarf virus (SRBSDV), a tentative species in the genus Fijivirus, family Reoviridae, is a novel rice virus transmitted by the white-backed planthopper (Sogatella furcifera). Since its discovery in 2001, SRBSDV has spread rapidly throughout eastern and southeastern Asia and caused large rice losses in China and Vietnam. Rice ragged stunt virus (RRSV) (genus Oryzavirus, family Reoviridae) is a common rice virus vectored by the brown planthopper (Nilaparvata lugens). RRSV is also widely distributed in eastern and southeastern Asia but has not previously caused serious problems in China owing to its low incidence. With SRBSDV's spread, however, RRSV has become increasingly common in China, and is frequently found in co-infection with SRBSDV. In this study, we show that SRBSDV and RRSV interact synergistically, the first example of synergism between plant viruses in the family Reoviridae. Rice plants co-infected with both viruses displayed enhanced stunting, earlier symptoms, and higher virus titers compared with singly infected plants. Furthermore, white-backed and brown planthoppers acquired SRBSDV and RRSV, respectively, from co-infected plants at higher rates. We propose that increased RRSV incidence in Chinese fields is partly due to synergism between SRBSDV and RRSV.

Abstract The southern rice black-streaked dwarf virus (SRBSDV) causes significant economic damage to rice crops. This virus is transmitted to rice plants by the planthopper Sogatella furcifera (Horváth) in a persistent, circular, and propagative manner. Researchers currently lack suitable methods for assaying the activity of SRBSDV in vitro and preserving the virus all year. We used a microinjection method to directly inject SRBSDV extracts into the hemocoel of S. furcifera nymphs. SRBSDV was subsequently detected by Reverse Transcription-Polymerase Chain Reaction in more than 56.7% of the insects after 5 d and 60% of healthy rice plants fed by these insects also became SRBSDV infected. Moreover, injecting planthopper with an extract of SRBSDV-infected rice plant that had been frozen at −80°C for 220 d caused 63.3% to become viruliferous. These results indicate that SRBSDV can be successfully transmitted to S. furcifera by microinjection, and that extracts of SRBSDV-infected rice plants frozen at −80°C for 220 d still contain sufficient active SRBSDV to infect S. furcifera. We provide a novel way to preserve SRBSDV all year by injecting S. furcifera with the SRBSDV extract.

Rice Ragged Stunt Virus

In recent years, Southern rice black-streaked dwarf virus (SRBSDV), a tentative species in the genus Fijivirus (family Reoviridae), has spread rapidly and caused serious rice losses in eastern and southeastern Asia. With this virus spread, Rice ragged stunt virus (RRSV, genus Oryzavirus, family Reoviridae) became more common in southern China, usually in co-infection with the former. SRBSDV and RRSV are transmitted by two different species of planthoppers, white-backed planthopper (WBPH, Sogatella furcifera) and brown planthopper (BPH, Nilaparvata lugens), respectively, in a persistent, circulative, propagative manner. In this study, using a Y-shape olfactometer-based device, we tested the host preference of three types of macropterous WBPH adults for healthy or SRBSDV-infected rice plants. The results showed that virus-free WBPHs significantly preferred infected rice plants to healthy plants, whereas both the viruliferous and nonviruliferous WBPHs preferred healthy plants to infected plants. In additional tests, we found that the BPHs significantly preferred healthy plants when they were virus free, whereas RRSV-carrying BPHs preferred SRBSDV-infected rice plants. From these findings, we propose that plant viruses may alter host selection preference of vectors to enhance their spread and that of insects vectoring another virus to result in co-infection with more than one virus.
