Insights Into Insect Vector Transmission and Epidemiology of Plant-Infecting Fijiviruses

“…Common plant hosts include flatsedge (Juncellus serotinus [Rottb.] C. B. Clarke) and variable flatsedge (Cyperus difformis L.) in family Cyperaceae, oat (Avena sativa L.), rice (Oryza sativa L.), sugarcane (Saccharum officinarum L.), maize (Zea mays L.), barley (Hordeum vulgare L.), rye (Secale cereale L.), wheat (Triticum aestivum L.), and pangola grass (a sterile triploid of Digitaria decumbens Stent) in family Gramineae, and garlic (Allium sativum L.) in family Liliaceae (Boito and Ornaghi, 2008;Li et al, 2012;Lefkowitz et al, 2018;Wu et al, 2020).…”

“…Now, it is considered to be the causal agent of rice black streaked dwarf and maize rough dwarf diseases, responsible for intermittent epidemics in East Asia and substantial yield losses over the last decades. Rice, maize, wheat, oats, and barley are its natural hosts with the similar symptoms as those of MRDV (Azuhata et al, 1993;Wu et al, 2020). In 2008, a RBSDV-like new virus, southern rice black streaked dwarf virus (SRBSDV), was reported in the south of China (Zhou et al, 2008) and caused serious yield losses in China, Vietnam and Japan during 2010s (Zhou et al, 2013).…”

Systematic Identification and Functional Analysis of Circular RNAs During Rice Black-Streaked Dwarf Virus Infection in the Laodelphax striatellus (Fallén) Midgut

“…RBSDV was first reported in Japan (Kuribayashi and Shinkai, 1952), with the first report in China in 1963 in Yuyao county, Zhejiang Province, and caused severe damage (Chen, 1964;Ren et al, 2016;Liu et al, 2020). RBSDV is transmitted in a persistent propagative manner by Laodelphax striatellus (Fallén) (Wu et al, 2020). The genome of RBSDV contains 10 double-stranded RNA (dsRNA) segments (S1 to S10) and encodes 13 proteins (Milne et al, 1973;Zhang et al, 2001a;He et al, 2020).…”

“…Over 76% of plant viruses are transmitted via insect vectors, including planthoppers, whiteflies, thrips, and aphids ( Hogenhout et al, 2008 ; Dader et al, 2017 ; Jia et al, 2018 ). Rice black-streaked dwarf virus (RBSDV) is a member of the genus Fijivirus within the family Reoviridae and is the causal agent of rice black-streaked dwarf and maize rough dwarf disease ( Zhang et al, 2001b ; Xu et al, 2014 ; Wu et al, 2020 ). RBSDV was first reported in Japan ( Kuribayashi and Shinkai, 1952 ), with the first report in China in 1963 in Yuyao county, Zhejiang Province, and caused severe damage ( Chen, 1964 ; Ren et al, 2016 ; Liu et al, 2020 ).…”

Comprehensive Identification and Characterization of Long Non-coding RNAs Associated With Rice Black-Streaked Dwarf Virus Infection in Laodelphax striatellus (Fallén) Midgut

“…It causes a severe reduction in rice yield through direct sucking and the viral diseases that it transmits. One of the important viruses transmitted by L. striatellus is Rice black-streaked dwarf virus (RBSDV), which belongs to the genus Fijivirus of the family Reoviridae and is transmitted in a persistent propagative manner ( Bai et al, 2001 ; Zhang et al, 2001 ; Wu et al, 2020 ). RBSDV only infects plants in the family Poaceae, such as Oryza sativa , Triticum aestivum , and Zea mays .…”
