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 ...

Molecular characterization of the largest and smallest genome segments, S1 and S12, of Rice gall dwarf virus

Virus Genes, 2007
The nucleotide sequences of segments S1 and S12 of a Chinese isolate of Rice gall dwarf virus (RGDV) were determined. This provides the first complete sequences of these segments. The complete sequence of S1, the largest genome segment of RGDV, was 4,505 nucleotides in length and was predicted to encode a large protein of 1,458 amino acids with a ...

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.

Autophagy pathway induced by a plant virus facilitates viral spread and transmission by its insect vector. [PDF]

PLoS Pathogens, 2017
Many viral pathogens are persistently transmitted by insect vectors and cause agricultural or health problems. Generally, an insect vector can use autophagy as an intrinsic antiviral defense mechanism against viral infection.

Secoviridae: a proposed family of plant viruses within the order Picornavirales that combines the families Sequiviridae and Comoviridae, the unassigned genera Cheravirus and Sadwavirus, and the proposed genus Torradovirus [PDF]

, 2009
The order Picornavirales includes several plant viruses that are currently classified into the families Comoviridae (genera Comovirus, Fabavirus and Nepovirus) and Sequiviridae (genera Sequivirus and Waikavirus) and into the unassigned genera Cheravirus ...
