Current knowledge of RNA virus biodiversity is both biased and fragmentary, reflecting a focus on culturable or disease-causing agents. [] Key Result Here we profile the transcriptomes of over 220 invertebrate species sampled across nine animal phyla and report the discovery of 1,445 RNA viruses, including some that are sufficiently divergent to comprise new families.
Meta-transcriptomics and the evolutionary biology of RNA viruses
Abundant and Diverse RNA Viruses in Insects Revealed by RNA-Seq Analysis: Ecological and Evolutionary Implications
Novel viruses were found to cover major categories of RNA viruses, and many formed novel clusters divergent from the previously described taxa, dramatically broadening the range of known RNA viruses in insects.
Revealing RNA virus diversity and evolution in unicellular algae transcriptomes
Both the limited number of viruses detected per sample and the low sequence identity to known RNA viruses imply that additional microalgal viruses exist that could not be detected at the current sequencing depth or were too divergent to be identified using sequence similarity.
High-Resolution Metatranscriptomics Reveals the Ecological Dynamics of Mosquito-Associated RNA Viruses in Western Australia
A metatranscriptomics analysis of 12 Western Australian mosquito populations structured by species and geographic location revealed that RNA viruses are some of the most important components of the mosquito transcriptome, and 19 new virus species from a diverse set of virus families are identified.
Viromes in marine ecosystems reveal remarkable invertebrate RNA virus diversity
This study revealed three marine invertebrate hantaviruses that are rooted to vertebrates, further supporting that hantviruses may have a marine origin and found evidence for possible host sharing and switch events during virus evolution.
Diversity and evolution of the animal virome.
The factors that determine the phylogenetic diversity and genomic structure of animal viruses on evolutionary timescales are outlined and how this impacts assessment of the risk of disease emergence in the short term is shown.
Expansion of the metazoan virosphere: progress, pitfalls, and prospects.
Deep Roots and Splendid Boughs of the Global Plant Virome.
The recently adopted comprehensive taxonomy of viruses based on phylogenomic analyses, as applied to the plant virome is introduced, and the evolutionary ancestry of distinct plant virus lineages to primordial genetic mobile elements is traced.
Metatranscriptomic Identification of Diverse and Divergent RNA Viruses in Green and Chlorarachniophyte Algae Cultures
18 novel RNA viruses in cultured samples from two major groups of microbial algae: the chlorophytes and the chlorarachniophytes are identified, including the first negative-sense (bunya-like) RNA virus in microalgae, as well as a distant homolog of the plant virus Virgaviridae.


Unprecedented genomic diversity of RNA viruses in arthropods reveals the ancestry of negative-sense RNA viruses
RNA sequencing of 70 arthropod species revealed that arthropods contain viruses that fall basal to major virus groups, including the vertebrate-specific arenaviruses, filoviruse, hantavirus, influenza viruses, lyssavirusing, and paramyxoviruses.
Endogenous viruses: insights into viral evolution and impact on host biology
It is argued that the conflict between hosts and viruses has led to the invention and diversification of molecular arsenals, which, in turn, promote the cellular co-option of endogenous viruses.
Discovery and initial analysis of novel viral genomes in the soybean cyst nematode.
It is shown that one plant parasitic nematodes species, Heterodera glycines, the soybean cyst nematode (SCN), harbours four different RNA viruses that are distantly related to nyaviruses and bornavIRuses, rhabdoviruses, bunyaviraluses and tenuiviruses.

It is argued persuasively that research in this area is limited by the size and detail of genome databases, combined with relevant epidemiologic and clinical information, such as precise geographic location, exact date of sampling, and transmission dynamics of the disease.
Discovery and Evolution of Bunyavirids in Arctic Phantom Midges and Ancient Bunyavirid-Like Sequences in Insect Genomes
The findings indicate that bunyavirid-host interactions in nonbloodsucking arthropods have been much more extensive than previously thought and may offer fresh insight into host reservoirs, potential sources of emerging disease, and major lifestyle shifts in the evolutionary history of viruses in the family Bunyviridae.
A tick-borne segmented RNA virus contains genome segments derived from unsegmented viral ancestors
This work discovered a previously unidentified segmented RNA virus of ticks that, uniquely, contained two segments derived from an unsegmented flavivirus, as well as two highly divergent segments of unknown origin.
Mitochondrial evolution.
Gene sequence data strongly support a monophyletic origin of the mitochondrion from a eubacterial ancestor shared with a subgroup of the alpha-Proteobacteria and raise the possibility that this organelle originated at essentially the same time as the nuclear component of the eukaryotic cell rather than in a separate, subsequent event.

The modular theory of virus evolution has clear experimental support among the temperate bacteriophages of the enteric bacteria. However, there is also similar genetic and DNA heteroduplex evidence
