Rice stripe disease, caused by rice stripe virus (RSV), is one of the major virus diseases in east Asia. Rice plants infected with RSV usually show symptoms such as chlorosis, weakness, necrosis in newly emerged leaves and stunting. To reveal rice cellular systems influenced by RSV infection, temporal changes in the transcriptome of RSV-infected plants were monitored by a customized rice oligoarray system. The transcriptome changes in RSV-infected plants indicated that protein-synthesis machineries and energy production in the mitochondrion were activated by RSV infection, whereas energy production in the chloroplast and synthesis of cell-structure components were suppressed. The transcription of genes related to host-defence systems under hormone signals and those for gene silencing were not activated at the early infection phase. Together with concurrent observation of virus concentration and symptom development, such transcriptome changes in RSV-infected plants suggest that different sets of various host genes are regulated depending on the development of disease symptoms and the accumulation of RSV. INTRODUCTIONRice stripe disease is the most severe virus disease of rice in east Asia. Typical symptoms are chlorosis and weakness on newly emerged leaves. The plant becomes considerably stunted when affected at the early growth stages (Ou, 1972). Rice stripe disease also causes necrosis of newly emerged leaves (Takahashi et al., 1991). The causal virus is Rice stripe virus (RSV), which belongs to the genus Tenuivirus (Falk & Tsai, 1998). RSV is transmitted by small brown planthopper (SBPH; Laodelphax striatellus), Terthron albovittatum, Unkanodes sapporonus and Unkanodes albifascia (Falk & Tsai, 1998;Ou, 1972). RSV has a thin, filamentous shape and no envelope. The genome consists of four single-stranded RNA segments; RNA1 is negative-sense and RNAs 2-4 are ambisense. Viral mRNAs transcribed from viral RNA or viral cRNA by RNA-dependent RNA polymerase are released to the cytoplasm. Subsequently, a 59-capped short ribonucleotide leader cleaved from the host mRNA is added to the viral mRNAs by cap-snatching. The 59-capped RSV RNA is transcribed efficiently in host cells (Falk & Tsai, 1998;Shimizu et al., 1996). Genes encoding a gene-silencing suppressor and movement proteins were also identified in the RSV genome (Lu et al., 2009;Xiong et al., 2008Xiong et al., , 2009. Although extensive functional analysis of the RSV genome has been conducted, there have been no reports on the interaction between RSV and rice plants, which may clarify the mechanisms behind the appearance of disease symptoms.Rice is a model cereal plant, for which many genomic and transcriptome resources and tools are already available (Liang et al., 2008;Ouyang et al., 2007; Rice Annotation Project, 2008; Rice Full-length cDNA Consortium, 2003). The elucidation of genome sequences and structures in diverse organisms has led to the development of various high-throughput genome and transcriptome analytical tools. Numerous transcriptome profiles in...

“…3 putative movement protein of rice stripe virus (Lu et al, 2009). Two rice DnaJs, OsDjA4 and OsDjA5, orthologous to yeast Ydj1, could rescue the defect in growth of the yeast mutant Ydj1, suggesting that these two proteins may possess similar roles to Ydj1 (Sarkar et al, 2013).…”

“…Since pC4 lacks an N-terminal signal peptide, a transmembrane domain, and a short C-terminal tail that might direct the viral MP to the PD, intracellular movement of pC4 might involve the interaction of pC4 with host cellular proteins that are transported by Golgi-derived vesicles and are eventually anchored to the PD. With a yeast two-hybrid system using pC4, two chaperone proteins, which have high degrees of identity with a DnaJ, and a Hsp20 have been isolated from a rice cDNA library (Lu et al, 2009). Continuing research on the movement of TMV, BYV, TSWV, and potato virus Y (Soellick et al, 2000; Prokhnevsky et al, 2002; Qiu et al, 2006; Hofius et al, 2007; Shimizu et al, 2009) has shown that DnaJ proteins bind to their partner heat shock proteins of the host plant cells and seem to act as a key regulator for conformational change in the movement form of the vRNPs that allows them to pass through the PD.…”

Recent progress in research on cell-to-cell movement of rice viruses

To adapt to plants as hosts, plant viruses have evolutionally needed the capacity to modify the host plasmodesmata (PD) that connect adjacent cells. Plant viruses have acquired one or more genes that encode movement proteins (MPs), which facilitate the cell-to-cell movement of infectious virus entities through PD to adjacent cells. Because of the diversity in their genome organization and in their coding sequences, rice viruses may each have a distinct cell-to-cell movement strategy. The complexity of their unusual genome organizations and replication strategies has so far hampered reverse genetic research on their genome in efforts to investigate virally encoded proteins that are involved in viral movement. However, the MP of a particular virus can complement defects in cell-to-cell movement of other distantly related or even unrelated viruses. Trans-complementation experiments using a combination of a movement-defective virus and viral proteins of interest to identify MPs of several rice viruses have recently been successful. In this article, we reviewed recent research that has advanced our understanding of cell-to-cell movement of rice viruses.
