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.

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.

JA-responsive R2R3-type MYB transcription factor OsMYB4P confers broad-spectrum antiviral immunity in rice. [PDF]

Plant Biotechnol J
Summary Jasmonic acid (JA) plays a critical role in antiviral defence in rice, where viral infection activates JA signalling by degrading Jasmonate ZIM domain (JAZ) proteins, thereby releasing transcription factors (TFs) to drive JA‐mediated defence gene expression. While the JA‐responsive TF OsMYC2 has been extensively studied in rice, the involvement

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 ...

A fijivirus major viroplasm protein shows RNA-stimulated ATPase activity by adopting pentameric and hexameric assemblies of dimers [PDF]

, 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

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 Plant Virus Glycoprotein Induces Autophagy by Activating the Toll7 Immune Pathway in Its Insect Vector. [PDF]

Mol Plant Pathol
The induction of autophagy in Laodelphax striatellus by Rice stripe virus (RSV) glycoprotein through the activation of the Toll7 immune pathway. ABSTRACT The Toll7 pathway is crucial in defending against diverse pathogenic microorganisms, including viruses.

Detection of Southern Rice Black-Streaked Dwarf Virus Using Western Blotting With P6

Frontiers in Sustainable Food Systems, 2021
The southern rice black-streaked dwarf virus (SRBSDV) is a severe threat to the yield and quality of rice products worldwide. Traditional detection methods for diagnosing SRBSDV infection show several false positives and thus provide inaccurate findings.

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.
