TLDR
The host specificity and other desirable traits exhibited by several members of this group make them potential natural enemies for intentional use against arthropod pests, such as triatoma virus against triatomine bugs that vector Chagas disease.Abstract:
Dicistroviridae is a family of small non-enveloped viruses with monopartite, linear, positive-sense RNA genomes of approximately 8–10 kb Viruses of all classified species infect arthropod hosts, with some having devastating economic consequences, such as acute bee paralysis virus in domesticated honeybees and taura syndrome virus in shrimp farming Conversely, the host specificity and other desirable traits exhibited by several members of this group make them potential natural enemies for intentional use against arthropod pests, such as triatoma virus against triatomine bugs that vector Chagas disease This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the taxonomy of the Dicistroviridae which is available at wwwictvglobal/report/dicistroviridaeread more

TL;DR: Analysis of a single RNA virome from the Yangshan Deep-Water Harbour in China enabled the recovery of more than 4,500 distinct RNA viruses, doubling the known set of RNA viruses to date, and provided insights into their biology.

TL;DR: These findings suggest transmission between arthropods and bats, perhaps through ingestion or hyperparasitism (viral infection of bat parasites).

Temporal changes in the viromes of Swedish Varroa-resistant and Varroa-susceptible honeybee populations.
TL;DR: RNA sequencing was employed to corroborate previous findings and identify other viral factors that may play a role in the enhanced survival of this mite resistant honeybee population on Gotland, Sweden.

TL;DR: A PCR-based technique was used to identify aphids prevalent in smallholder bean farms and next generation sequencing shotgun metagenomics to examine the diversity of viruses present in aphids and in maize leaf samples, demonstrating the broad occurrence of these dicistroviruses.

RNA-viromics reveals diverse communities of soil RNA viruses with the potential to affect grassland ecosystems across multiple trophic levels
TL;DR: In this article , the authors identify 3462 contigs in RNA viromes from purified virus-like-particles in five soil-types and assessed their spatial distribution, phylogenetic diversity and potential host ranges.

Journal ArticleDOI
Divergent IRES elements in invertebrates.
TL;DR: The existence of this mechanism suggests that the repertoire of open reading frames in the genome may be greater than anticipated, and the mechanism of initiating translation at non-AUG codons and the regulation of this IRES in vivo are examined.
Journal ArticleDOI
Functional analysis of structural motifs in dicistroviruses.
TL;DR: The family Dicistroviridae is composed of positive-stranded RNA viruses which have monopartite genomes, which carry genome-linked virus proteins (VPg) and poly (A) tails and contains an internal ribosome entry site (IRES).

Effect of oral infection with Kashmir bee virus and Israeli acute paralysis virus on bumblebee (Bombus terrestris) reproductive success
TL;DR: Israeli acute paralysis virus together with Acute bee paralysis virus (ABPV) and Kashmir bee virus (KBV) constitute a complex of closely related dicistroviruses and it is vital to understand how viral prevalence can affect wild bee populations because disturbance of the natural host-virus association may deteriorate the already critically endangered status of many bumblebee species.

TL;DR: Using a CrPV replicon that uncouples viral translation and replication, it is shown that the increase in IGR IRES translation is dependent on expression of non-structural proteins and is greatly stimulated when replication is active.

Triatoma virus recombinant VP4 protein induces membrane permeability through dynamic pores
Rubén Sánchez-Eugenia,Julen Goikolea,David Gil-Carton,Lissete Sánchez-Magraner,Diego M. A. Guérin +4 more
TL;DR: It is shown that the triatoma virus VP4 protein is able to produce membrane permeabilization in model membranes by the formation of heterogeneous dynamic pores, which may be involved in the genome transfer or cell entry steps during viral infection.
