Discovery of a novel double-stranded DNA virus associated with ant labial gland disease reveals its long-term interaction with ants journals.asm.org/doi/10.1128/...
Discovery of a novel double-stranded DNA virus associated with ant labial gland disease reveals its long-term interaction with ants | Journal of Virology
Ants, as highly eusocial insects, play vital roles in ecosystems worldwide. While numerous RNA viruses have been documented in ants, no double-stranded DNA (dsDNA) virus has previously been confirmed to infect them. Labial gland disease, reported for decades, lacks a clearly defined cause until now. Here, we identify and characterize a large filamentous dsDNA virus, Camponotus japonicus labial gland disease virus (CjLGDV), from the swollen labial gland of C. japonicus, and a closely related Anoplolepis gracilipes labial gland disease virus in A. gracilipes. Phylogenetic and genomic analyses of the two viruses support the establishment of a new viral family within the order Lefavirales, class Naldaviricetes. The discovery of endogenous viral elements related to CjLGDV in multiple ant genomes suggests the historical infection of CjLGDV-like viruses in ants. These findings broaden the known host range of naldaviricetes and shed new light on the diversity, evolution, and host interaction of large dsDNA viruses in arthropods.
