Reduced cold tolerance of viral-infected leafhoppers attenuates viral persistent epidemics [PDF]

mBio
Most arthropod-borne viruses produce intermittent epidemics in infected plants. However, the underlying mechanisms of these epidemics are unclear. Here, we demonstrated that rice stripe mosaic virus (RSMV), a viral pathogen, significantly increases the ...

Infection Characteristics of Rice Stripe Mosaic Virus in the Body of the Vector Leafhoppers [PDF]

Frontiers in Microbiology, 2019
Rice stripe mosaic virus (RSMV), a novel species of Cytorhabdovirus, is transmitted by the leafhopper Recilia dorsalis in a persistent-propagative manner.

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.

An insect symbiotic virus promotes the transmission of a phytoarbovirus via inhibiting E3 ubiquitin ligase Sina. [PDF]

PLoS Pathogens
Co-infection with symbiotic viruses and arboviruses with synergistic effects in insect vectors are common in nature, but the underlying mechanism remains elusive.

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.

Geographic Distribution, Genetic Variability and Biological Properties of Rice Orange Leaf Phytoplasma in Southeast Asia [PDF]

Pathogens, 2021
Rice orange leaf phytoplasma (ROLP) causes clear orange to yellowish leaf discoloration and severe stunting in rice seedlings. The ecological and biological characteristics of ROLP are largely unknown because the disease has not widely caused serious ...

Comparative Analysis of Mitogenomes in Leafhopper Tribe Deltocephalini (Hemiptera: Cicadellidae: Deltocephalinae): Structural Conservatism and Phylogeny. [PDF]

Ecol Evol
In this study, we sequenced the complete mitogenomes of 14 species belonging to four genera of tribe Deltocephalini from China and compared them with the two previously reported mitogenomes for this tribe. Phylogenetic analysis of different combinations of protein‐coding and ribosomal genes using maximum likelihood and Bayesian inference under ...

Reemerging Rice Orange Leaf Phytoplasma with Varying Symptoms Expressions and Its Transmission by a New Leafhopper Vector—Nephotettix virescens Distant [PDF]

Pathogens, 2020
Rice orange leaf phytoplasma (ROLP) belongs to the “Candidatus Phytoplasma asteris” 16SrI-B subgroup, which is solely transmitted by the zigzag-striped leafhopper (Recilia dorsalis Motchulsky) and the green leafhopper (Nephotettix cincticeps Uhler ...

Exploration of an Actin Promoter-Based Transient Expression Vector to Trace the Cellular Localization of Nucleorhabdovirus Proteins in Leafhopper Cultured Cells [PDF]

Frontiers in Microbiology, 2018
Continuously cultured cell lines derived from planthopper and leafhopper have greatly facilitated the investigation of rice viruses transmitted by these insects. However, the lack of a suitable transient expression vector has limited their utility. Here,
