Description

Viruses are justifiably regarded as the most effective transmission vectors because they are small and covert, ubiquitous in nature (every living thing is infected with at least one virus), and even integrated into human DNA. Their evolutionary trimmed minimal genome, however, is obligately dependent on the host cell for genome replication, viral protein synthesis, and progeny virion assembly, prohibiting them from being called living creatures. Viruses have devised a surprising array of strategies to control of the host cell's transcription and translation processes. They have lately made significant progress in their knowledge of the molecular impacts of viral infection on host cell transcription, notably translation.

This also highlighted the importance of RNA-based techniques for viruses to manipulate biological processes. The priming of the retroviral reverse transcriptase with host initiator transfer RNA (tRNA) was one of the first reports of a virus employing an RNA component to aid replication.

The use of (virus-encoded) tRNAs and tRNA-like structures, RNA degradation and fragmentation, and post-transcriptional chemical modification of viral messenger RNA (mRNA) transcripts and viral genomic RNA are all components of viruses' repertoire for promoting replication and inhibiting host cell immune responses. Furthermore, eukaryotic research have greatly contributed to their understanding of RNA-based regulation, whereas many microbial model systems are remains limited.

Viruses have been in a constant arms race with their hosts throughout evolution, attempting to achieve a balance between effective viral multiplication and host cell survival. This is typically achieved by a complicated network of viral and host factors. The focus here is on the function of specific RNA components and what they can learn about the protein synthesis regulation by looking at how viruses interact with the translation machiner via these RNA components. Epitranscriptomic extension of the genetic code is a powerful strategy for managing translation fidelity and processivity, as well as viral protein synthesis. Because viruses are fully dependent on the host cell translation machinery, this discrepancy in codon usage and availability should manifest as poor translation efficiency of viral transcripts and limited viral reproduction. Surprisingly, many viruses with a high level of codon mismatch can nevertheless efficiently manufacture their proteins. This is due to the viruses' ability to encode their own tRNAs, which are acquired by horizontal gene transfer and increase the host's codon availability. Since the first discovery of translationally active vtRNAs in the bacteriophage T4 virus, vtRNAs have been discovered in viruses from all walks of life. In fact, a study of 13200 viruses found vtRNA genes in up to 14% of the genomes, with myoviruses and siphoviruses head-tailed phages that target prokaryotes and archaea having the highest prevalence.

Conclusion

Extensive evidence suggests that viruses have evolved complex techniques to exploit cellular components, machinery, and networks to aid in their replication. Despite their long-standing grasp of numerous RNA-based elements and mechanisms, their comprehension and appreciation of the complex interactions between viruses and their hosts remains limited. Furthermore, with the exception of a few well-studied laboratory models such as E. coli and its phages, the extent to which these interactions are evolutionarily conserved remains largely unknown. As a result, their understanding of the relationship between microbial hosts and their viruses is restricted. These organisms often thrive in extreme environments, displaying remarkable RNA adaptations that enable their survival in sun salterns, hot springs, or even the depths of the ocean.
