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.

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.

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
