Beyond a few bases: methods for large DNA insertion and gene targeting in plants. [PDF]

Plant J
SUMMARY Genome editing technologies like CRISPR/Cas have greatly accelerated the pace of both fundamental research and translational applications in agriculture. However, many plant biologists are functionally limited to creating small, targeted DNA changes or large, random DNA insertions.

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.

Identification of Pns12 as the second silencing suppressor of Rice gall dwarf virus [PDF]

Science China Life Sciences, 2011
RNA silencing is a conserved mechanism found ubiquitously in eukaryotic organisms. It has been used to regulate gene expression and development. In addition, RNA silencing serves as an important mechanism in plants' defense against invasive nucleic acids, such as viruses, transposons, and transgenes.

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.

Morphology and Nucleic Acid of Rice Gall Dwarf Virus

Intervirology, 1985
In negative stain preparations, the particles of rice gall dwarf virus (RGDV) had the form of angular icosahedra, approximately 65 nm in diameter, and resembled Phytoreovirus particles. The genomic double-stranded RNA of RGDV was fractionated by PAGE into 12 segments similar to those of the RNAs of the phytoreoviruses, wound tumor virus and rice dwarf ...

Life cycle of phytoreoviruses visualized by electron microscopy and tomography

Frontiers in Microbiology, 2013
Rice dwarf virus (RDV) and Rice gall dwarf virus (RGDV), members of the genus Phytoreovirus in the family Reoviridae, are known as agents of rice disease, because their spread results in substantial economic damage in many Asian countries.

Viral pathogens hitchhike with insect sperm for paternal transmission

Nature Communications, 2019
Arbovirus vertical transmission is commonly mediated by transovarial passage of female insect vectors. Here, the authors show that Rice gall dwarf virus can be transmitted by male leafhoppers via interactions of the viral capsid and heparan sulfate ...

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 ...
