Rice Gall Dwarf Virus Promotes the Propagation and Transmission of Rice Stripe Mosaic Virus by Co-infected Insect Vectors [PDF]

Frontiers in Microbiology, 2022
Rice stripe mosaic virus (RSMV), a newly discovered plant cytorhabdovirus, and rice gall dwarf virus (RGDV), a plant reovirus, are transmitted by leafhopper Recilia dorsalis in a persistent-propagative manner. In this study, field surveys in Luoding city,

Delivery of Rice Gall Dwarf Virus Into Plant Phloem by Its Leafhopper Vectors Activates Callose Deposition to Enhance Viral Transmission [PDF]

Frontiers in Microbiology, 2021
Rice gall dwarf virus (RGDV) and its leafhopper vector Recilia dorsalis are plant phloem-inhabiting pests. Currently, how the delivery of plant viruses into plant phloem via piercing-sucking insects modulates callose deposition to promote viral ...

Rice gall dwarf virus exploits tubules to facilitate viral spread among cultured insect vector cells derived from leafhopper Recilia dorsalis [PDF]

Frontiers in Microbiology, 2013
Rice gall dwarf virus (RGDV), a member of the family Reoviridae, causes repeated epidemics in rice fields in southern China. An RGDV isolate collected from Guangdong Province (southern China) is mainly transmitted by leafhopper vector Recilia dorsalis in

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

Advanced Science
Lysozymes are well‐known for their ability to cleave bacterial peptidoglycan, but their potential to hydrolyze viral components as a form of antiviral defense remains poorly understood.

Plant Virus‐Induced Inheritable Apoptosis Drives Reproductive Costs in Female Insect Vectors to Balance Viral Biparental Transmission [PDF]

Advanced Science
Insect‐borne pathogens often reduce the reproductive fitness of insect vectors. Rice gall dwarf virus (RGDV) is biparentally transmitted to the offspring of its leafhopper vector.

Expression of rice gall dwarf virus outer coat protein gene (S8) in insect cells [PDF]

Virologica Sinica, 2010
To obtain the P8 protein of Rice gall dwarf virus (RGDV) with biological activity, its outer coat protein gene S8 was expressed in Spodoptera frugiperda (Sf9) insect cells using the baculovirus expression system. The S8 gene was subcloned into the pFastBac™1 vector, to produce the recombinant baculovirus transfer vector pFB-S8.

Reoviruses hijack the SMARCB1-MYC transcriptional regulation complex to activate autophagy for persistent viral infection in leafhopper vector. [PDF]

PLoS Pathogens
Autophagy plays a crucial role in virus-host interactions, as viral components and particles can be degraded by the host's autophagic machinery. Additionally, some viruses can hijack autophagy for their own benefit. However, the mechanisms underlying the

Loss-of-Function of Two PD-Associated Proteins Confers Resistance to Rice Stripe Virus. [PDF]

Mol Plant Pathol
Rice importin α4 and flotillin 1, as proteins associated with plasmodesmata (PD), facilitate the enlargement of PD apertures by diminishing callose deposition at these structures, thereby promoting the intercellular translocation of RSV. ABSTRACT Plant viruses usually exploit plasmodesmata (PDs) to achieve cellular infection in host plants. Although PD‐

Gelsolin of insect vectors negatively regulates actin-based tubule motility of plant reoviruses

Phytopathology Research, 2019
Most plant reoviruses encode a type of nonstructural protein that assembles tubular structures to package virions for viral spread in planthopper or leafhopper vectors.
