Delivery of Rice Gall Dwarf Virus Into Plant Phloem by Its Leafhopper Vectors Activates Callose Deposition to Enhance Viral Transmission [PDF]
Rice gall dwarf virus (RGDV) and its leafhopper vector Recilia dorsalis are plant phloem-inhabiting pests. Currently, how the delivery of plant viruses into plant phloem via piercing-sucking insects modulates callose deposition to promote viral ...

Insect I-Type Lysozymes Function as Antiviral Proteases by Forming Biomolecular Condensates. [PDF]
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.

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

Rice stripe mosaic virus M protein antagonizes G-protein-induced antiviral autophagy in insect vectors. [PDF]
In the field, 80% of plant viruses are transmitted by insect vectors. When ingested by a sap-sucking insect such as Recilia dorsalis, persistently transmitted viruses such as rice stripe mosaic virus (RSMV) infect the gut epithelium and eventually pass ...

Plant viruses exploit insect salivary GAPDH to modulate plant defenses [PDF]
Salivary proteins of insect herbivores can suppress plant defenses, but the roles of many remain elusive. One such protein is glyceraldehyde-3-phosphate dehydrogenase (GAPDH) from the saliva of the Recilia dorsalis (RdGAPDH) leafhopper, which is known to

Reoviruses hijack the SMARCB1-MYC transcriptional regulation complex to activate autophagy for persistent viral infection in leafhopper vector. [PDF]
Autophagy plays a crucial role in virus-host interactions, as viral components and particles can be degraded by the host's autophagic machinery. Additionally, some viruses can hijack autophagy for their own benefit. However, the mechanisms underlying the

Plant Virus-Induced Inheritable Apoptosis Drives Reproductive Costs in Female Insect Vectors to Balance Viral Biparental Transmission. [PDF]
Rice gall dwarf virus (RGDV), transmitted biparentally by leafhopper vector to their offspring, exploits the capsid protein to induce inheritable ovarian apoptosis via insulin‐driven PI3K/AKT/FoxO signaling axis. This mechanism enhances infection but reduces female reproductive fitness, causing inefficient maternal transmission.
