Fibrillar structures induced by a plant reovirus target mitochondria to activate typical apoptotic response and promote viral infection in insect vectors.

PLoS Pathogens, 2019
Numerous plant viruses that cause significant agricultural problems are persistently transmitted by insect vectors. We wanted to see if apoptosis was involved in viral infection process in the vector. We found that a plant reovirus (rice gall dwarf virus,

Nucleotide Sequence of Segment S9 of the Genome of Rice Gall Dwarf Virus

Journal of General Virology, 1990
DNA complementary to the ninth largest (S9) of the 12 genome segments of rice gall dwarf virus (RGDV) was cloned and its sequence was determined. It is 1202 nucleotides in length and contains one open reading frame which extends for 969 nucleotides from nucleotide 26. It encodes a polypeptide of 323 amino acids with an Mr of 35,560.

Assembly of viroplasms by viral nonstructural protein Pns9 is essential for persistent infection of rice gall dwarf virus in its insect vector

Virus Research, 2015
Rice gall dwarf virus (RGDV), a plant reovirus, is transmitted by leafhopper vector Recilia dorsalis in a persistent-propagative manner. In a sequential study of RGDV infection of its insect vector, the virus initially infected the filter chamber epithelium, then directly crossed the basal lamina into the visceral muscles, from where it spread ...

Emerging Viral Threats in Rice: A Decade of Discovery and Implications for Crop Protection. [PDF]

Plant Cell Environ
ABSTRACT Rice viral diseases pose severe threats to global food security, with over 20 viruses identified in China alone. The advent of high‐throughput sequencing has accelerated the discovery of novel viruses in cultivated and wild rice, unveiling previously undetected threats.

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‐

A leafhopper saliva protein mediates horizontal transmission of viral pathogens from insect vectors into rice phloem

Communications Biology, 2022
CBP, a calcium binding protein found in insect saliva, allows for the transmission of the devastating rice gall dwarf virus into plant phloem. This interaction with CBP is compounded by stronger feeding barriers, more frequent probing behavior, and ...

Arboviruses and symbiotic viruses cooperatively hijack insect sperm-specific proteins for paternal transmission

Nature Communications, 2023
Arboviruses and symbiotic viruses can be paternally transmitted by male insects to their offspring, but the mechanism remains largely unknown. Here, the authors identify the sperm-specific serpin protein HongrES1 of the leafhopper Recilia dorsalis as a ...

A nonstructural protein encoded by a rice reovirus induces an incomplete autophagy to promote viral spread in insect vectors.

PLoS Pathogens, 2022
Viruses can hijack autophagosomes as the nonlytic release vehicles in cultured host cells. However, how autophagosome-mediated viral spread occurs in infected host tissues or organs in vivo remains poorly understood.

All Roads Lead to Rome: Pathways to Engineering Disease Resistance in Plants. [PDF]

Adv Sci (Weinh)
Crops lost to diseases necessitate a deeper understanding of plant immunity and the development of disease resistance. Here, the arms‐race between plants and pathogens is briefly described, and a comprehensive overview of the current and emerging strategies for engineering disease resistance in plants is provided.

Table_1_Rice Gall Dwarf Virus Promotes the Propagation and Transmission of Rice Stripe Mosaic Virus by Co-infected Insect Vectors.doc

, 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,
