Co-infection of two reoviruses increases both viruses accumulation in rice by up-regulating of viroplasm components and movement proteins bilaterally and RNA silencing suppressor unilaterally

Virology Journal, 2017
Background Synergism between southern rice black-streaked dwarf virus (SRBSDV) and rice ragged stunt virus (RRSV) not only aggravates disease symptoms but also enhances their vector acquisition efficiencies by increasing both viruses’ titers in co ...

Transcriptome and comparative gene expression analysis of Sogatella furcifera (Horváth) in response to southern rice black-streaked dwarf virus. [PDF]

PLoS ONE, 2012
BACKGROUND: The white backed planthopper (WBPH), Sogatella furcifera (Horváth), causes great damage to many crops by direct feeding or transmitting plant viruses.

Characterization of full-length long noncoding RNAs and identification of virus-responsive lncRNAs in Sogatella furcifera [PDF]

Frontiers in Microbiology
Long non-coding RNAs (lncRNAs) are crucial regulators of development and stress responses in eukaryotes, but their roles in non-model insects, particularly rice planthoppers, remain poorly characterized.

Interaction Research on the Antiviral Molecule Dufulin Targeting on Southern Rice Black Streaked Dwarf Virus P9-1 Nonstructural Protein

Viruses, 2015
ern rice black streaked dwarf virus (SRBSDV) causes severe harm to rice production. Unfortunately, studies on effective antiviral drugs against SRBSDV and interaction mechanism of antiviral molecule targeting on SRBSDV have not been reported.

Evaluation of Rice Resistance to Southern Rice Black-Streaked Dwarf Virus and Rice Ragged Stunt Virus through Combined Field Tests, Quantitative Real-Time PCR, and Proteome Analysis

Viruses, 2017
Diseases caused by southern rice black-streaked dwarf virus (SRBSDV) and rice ragged stunt virus (RRSV) considerably decrease grain yield. Therefore, determining rice cultivars with high resistance to SRBSDV and RRSV is necessary.

The mRNA surveillance factor Pelo restricts rice virus propagation in insect vectors and host plants

Phytopathology Research
Many devastating plant viruses are transmitted by insect vectors among plant hosts in a persistent-propagative manner. Pelota (Pelo) is an evolutionarily conserved protein involved in the mRNA surveillance system.

Insect I-Type Lysozymes Function as Antiviral Proteases by Forming Biomolecular Condensates. [PDF]

Adv Sci (Weinh)
Upon rice viral infection, the insect vector activates the Toll–MyD88–Dorsal signaling cascade, inducing i‐type lysozyme (Lyz‐I1) expression. Lyz‐I1 functions as an antiviral protease through its conserved catalytic dyad Glu/Asp (E/D), mediating cleavage of viral proteins at specific Lys (K) residues.

Entomopathogenic Effects of the Plant-Associated Fungus Ochroconis guangxiensis X22 Strain on the Physiological and Metabolic State of the Rice-Pest Planthopper, Sogatella furcifera

Agriculture
The white-backed planthopper (Sogatella furcifera) is a major pest in rice-growing regions worldwide. It severely limits rice production through piercing–sucking feeding, oviposition injury, and by efficiently transmitting the Southern Rice Black ...

JA-responsive R2R3-type MYB transcription factor OsMYB4P confers broad-spectrum antiviral immunity in rice. [PDF]

Plant Biotechnol J
Summary Jasmonic acid (JA) plays a critical role in antiviral defence in rice, where viral infection activates JA signalling by degrading Jasmonate ZIM domain (JAZ) proteins, thereby releasing transcription factors (TFs) to drive JA‐mediated defence gene expression. While the JA‐responsive TF OsMYC2 has been extensively studied in rice, the involvement
