“…There are some common features shared by the different RNA segments. At the extreme 5′ and 3′ terminals of the sense strand of each segment, there is a conserved sequence of 5′‐AAGTTTT…CAGCTA(G)T(C/A)T(C)GTC‐3′, which is similar to the conserved terminal sequences reported in the segments of other viruses in Fijivirus group 2 (Marzachi et al ., ; Zhang et al ., ,b; Guzmán et al ., ; Xue et al ., ). This genus‐specific sequence is thought to act as a recognition signal for replication and viral RNA packaging (Anzola et al ., ).…”

Southern rice black‐streaked dwarf virus (SRBSDV) was first reported in southern China in 2001 and causes a striking disease on rice and maize that leads to serious yield losses in several East Asian countries, such as China, Vietnam and Japan. A large research effort has been directed to understanding the virus and controlling the disease. Its geographic distribution, disease cycle via its insect vector, genome organization, relationship with host plants, and epidemiology are summarized in this review and the important role played by the vector, the white‐backed planthopper (Sogatella furcifera), is emphasized. Countermeasures to control the disease that have been developed and applied include molecular detection for precise forecasting, chemical, physical, and ecological pest management. There is widespread insecticide resistance in the vector population but it is hoped that current efforts to develop rice cultivars resistant to the virus will eventually provide effective and cost‐effective control.

“…Infection status of vectors might have differentially effected their responses to volatile compounds emitted from host plants (Wang et al 2013) The white-backed planthopper is a migratory rice pest and a vector of SRBSDV (Zhou et al 2008). SRBSDV was Þrst reported in 2001 (Zhou et al 2008) and thereafter devastated rice crop from 2009 to 2011 and in 2013 in southern China and in Vietnam (Wang et al 2010;Zhou et al 2008Zhou et al , 2010Hoang et al 2011;Xue et al 2013). Rice plants infected by SRBSVD present stunting and dark green leaves in the early stages and display small enations on stem and abnormal tiller formation on upper plant parts at the late stages .…”

Performance of insect vectors can be influenced by the viruses they transmit, either directly by infection of the vectors or indirectly via infection of the host plants. Southern rice black-streaked dwarf virus (SRBSDV) is a propagative virus transmitted by the white-backed planthopper, Sogatella furcifera (Hovath). To elucidate the influence of SRBSDV on the performance of white-backed planthopper, life parameters of viruliferous and nonviruliferous white-backed planthopper fed rice seedlings infected or noninfected with SRBSDV were measured using a factorial design. Regardless of the infection status of the rice plant host, viruliferous white-backed planthopper nymphs took longer to develop from nymph to adult than did nonviruliferous nymphs. Viruliferous white-backed planthopper females deposited fewer eggs than nonviruliferous females and both viruliferous and nonviruliferous white-backed planthopper females laid fewer eggs on infected than on noninfected plants. Longevity of white-backed planthopper females was also affected by the infection status of the rice plant and white-backed planthopper. Nonviruliferous white-backed planthopper females that fed on infected rice plants lived longer than the other three treatment groups. These results indicate that the performance of white-backed planthopper is affected by SRBSDV either directly (by infection of white-backed planthopper) or indirectly (by infection of rice plant). The extended development of viruliferous nymphs and the prolonged life span of nonviruliferous adults on infected plants may increase their likelihood of transmitting virus, which would increase virus spread.

Complete Genomic Sequence of Southern Rice Blacked-Dwarf Virus, a Novel Fijivirus, from Vietnam

Abstract: The nucleotide sequences of the ten genomic segments of a Vietnam isolate of southern rice blacked-dwarf virus were determined. This complete genomic sequence will help to further understand the viral etiology (origin of viral pathogen) and phylogenetic relationships among fijiviruses.
