Low-dose of oligosaccharins boosts antiviral immunity through induction of multiple defense pathways in rice

Phytopathology Research
Oligosaccharins, widely recognized as plant immunity inducers, have been applied and studied for enhancing antiviral defenses in rice over the years. However, due to the complex induction mechanism in rice, further studies are needed.

Identification and Characterization of Three Novel Solemo-like Viruses in the White-Backed Planthopper, Sogatella furcifera [PDF]

Insects
Agricultural insects play a crucial role in transmitting plant viruses and host a considerable number of insect-specific viruses (ISVs). Among these insects, the white-backed planthoppers (WBPH; Sogatella furcifera, Hemiptera: Delphacidae) are noteworthy

Evolutionary-Distinct Viral Proteins Subvert Rice Broad-Spectrum Antiviral Immunity Mediated by the RAV15-MYC2 Module. [PDF]

Adv Sci (Weinh)
Diverse viruses employ various pathogenicity strategies to inhibit host antiviral defense for successful infection. However, the pathogenic mechanisms conserved among different viruses have rarely been studied. This discovery unveils a broad‐spectrum counter‐defense strategy across evolutionarily distinct viral proteins, highlighting a new strategy for

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.

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.

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‐

Plasmodesmata-associated Flotillin positively regulates broad-spectrum virus cell-to-cell trafficking. [PDF]

Plant Biotechnol J
Summary Viral diseases seriously threaten rice production. Plasmodesmata (PD)‐associated proteins are deemed to play a key role in viral infection in host plants. However, few PD‐associated proteins have been discovered in rice to afford viral infection.
