Identification of a movement protein of the tenuivirus rice stripe virus.
Rice stripe virus (RSV) is the type member of the genus Tenuivirus. RSV has four single-stranded RNAs and causes severe disease in rice fields in different parts of China. To date, no reports have described how RSV spreads within host plants or the viral and/or host factor(s) required for tenuivirus movement. We investigated functions of six RSV-encoded proteins using trans-complementation expe...
متن کاملInteraction of a plant virus-encoded protein with the major nucleolar protein fibrillarin is required for systemic virus infection.
The nucleolus and specific nucleolar proteins are involved in the life cycles of some plant and animal viruses, but the functions of these proteins and of nucleolar trafficking in virus infections are largely unknown. The ORF3 protein of the plant virus, groundnut rosette virus (an umbravirus), has been shown to cycle through the nucleus, passing through Cajal bodies to the nucleolus and then e...
متن کاملAn insect cell line derived from the small brown planthopper supports replication of rice stripe virus, a tenuivirus.
A cell line from the small brown planthopper (SBPH; Laodelphax striatellus) was established to study replication of rice stripe virus (RSV), a tenuivirus. The SBPH cell line, which had been subcultured through 30 passages, formed monolayers of epithelial-like cells. Inoculation of cultured vector cells with RSV resulted in a persistent infection. During viral infection in the SBPH cell line, th...
متن کاملGenetically engineered rice resistant to rice stripe virus, an insect-transmitted virus.
The coat protein (CP) gene of rice stripe virus was introduced into two japonica varieties of rice by electroporation of protoplasts. The resultant transgenic plants expressed the CP at high levels (up to 0.5% of total soluble protein) and exhibited a significant level of resistance to virus infection. Plants derived from selfed progeny of the primary transformants also expressed the CP and sho...
متن کاملRelationship Between Maize Stripe Virus and Rice Stripe Virus
Maize stripe virus (MStpV) and rice stripe virus (RSV) were compared serologically, chemically and physically. Cross-reactions in agar gel double-diffusion and microprecipitin tests, and neutralization of MStpV infectivity by antiserum to either virus showed that MStpV and RSV are serologically related. Both viruses sedimented slowly and in a heterodisperse manner in rate-zonal sucrose gradient...
