MicroRNA750-3p Targets Processing of Precursor 7 to Suppress Rice Black-Streaked Dwarf Virus Propagation in Vector Laodelphax striatellus [PDF]

Viruses
MicroRNAs (miRNAs) are non-coding RNAs, which, as members of the RNA interference pathway, play a pivotal role in antiviral infection. Almost 80% of plant viruses are transmitted by insect vectors; however, little is known about the interaction of the ...

Dynamic alterations and ecological implications of rice rhizosphere bacterial communities induced by an insect-transmitted reovirus across space and time [PDF]

Microbiome
Background Cereal diseases caused by insect-transmitted viruses are challenging to forecast and control because of their intermittent outbreak patterns, which are usually attributed to increased population densities of vector insects due to cereal crop ...

A Review of Vector-Borne Rice Viruses [PDF]

Viruses, 2022
Rice (Oryza sativa L.) is one of the major staple foods for global consumption. A major roadblock to global rice production is persistent loss of crops caused by plant diseases, including rice blast, sheath blight, bacterial blight, and particularly ...

The JAK-STAT pathway promotes persistent viral infection by activating apoptosis in insect vectors. [PDF]

PLoS Pathogens, 2023
The Janus kinase-signal transducer and activator of transcription (JAK-STAT) pathway is an evolutionarily conserved signaling pathway that can regulate various biological processes.

A Fijivirus Major Viroplasm Protein Shows RNA-Stimulated ATPase Activity by Adopting Pentameric and Hexameric Assemblies of Dimers. [PDF]

mBio, 2023
Fijiviruses replicate and package their genomes within viroplasms in a process involving RNA-RNA and RNA-protein interactions. Here, we demonstrate that the 24 C-terminal residues (C-arm) of the P9-1 major viroplasm protein of the mal de Río Cuarto virus

Differentiation Trajectory of Virus-Induced Tumour Cells in Rice Revealed by Single-Cell RNA Sequencing. [PDF]

Plant Biotechnol J
ABSTRACT Many plant viruses trigger abnormal differentiation and development of host cells, causing distinct symptoms. Here, in a single‐cell RNA sequence analysis, we find transcriptional heterogeneity between cells from rice leaf sheaths that are infected with rice black streaked dwarf virus (RBSDV) and from those that are virus‐free.

Rice black-streaked dwarf virus-encoded P6 protein impairs OsPelota-mediated antiviral RNA decay defense via promoting OsSCE1b ubiquitination and degradation in rice. [PDF]

J Integr Plant Biol
The P6 protein encoded by rice black‐streaked dwarf virus enhances degradation of the rice SUMO E2 conjugating enzyme OsSCE1b through the ubiquitin/26S proteasome pathway; OsSCE1b degradation results in decreased SUMOylation of OsPelota, thereby suppressing RNA decay‐dependent antiviral defenses in rice. ABSTRACT Rice black‐streaked dwarf virus (RBSDV)

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.

Emerging Roles of Receptor-Like Proteins in Plant Immunity: Crosstalk, Signalling Networks and Prospects for Disease Resistance Breeding. [PDF]

Mol Plant Pathol
RLPs are pivotal immune hubs, interfacing with RLKs in layered defence networks. Understanding their cross‐talk and evolution unlocks potential for engineering durable resistance in crops. ABSTRACT Receptor‐like proteins (RLPs) are cell‐surface receptors that recognise pathogen‐ or damage‐associated molecular patterns to activate immune responses, and ...
