Origins and evolution of viruses of eukaryotes: The ultimate modularity

Abstract: Viruses and other selfish genetic elements are dominant entities in the biosphere, with respect to both physical abundance and genetic diversity. Various selfish elements parasitize on all cellular life forms. The relative abundances of different classes of viruses are dramatically different between prokaryotes and eukaryotes. In prokaryotes, the great majority of viruses possess double-stranded (ds) DNA genomes, with a substantial minority of single-stranded (ss) DNA viruses and only limited presence of RNA v… Show more

“…It has also discovered new deep branches, such as clades of insectinfecting Partitiviruses (Webster et al 2015;Shi et al 2016a) and Luteo/Sobemo-like viruses (Tokarz et al 2014;Shi et al 2016a), and whole new families, such as the Chuviruses (Li et al 2015). This in turn has led to renewed interest in inferring deep viral phylogenies (Koonin et al 2015;Shi et al 2016a), and has prompted proposals for large-scale updates of higher-level virus taxonomy (Aiewsakun and Simmonds 2018). More importantly, metagenomics now contributes to our thinking on virus evolution.…”

“…single-particle cryo-EM | Allolevivirus | ssRNA virus | genomic RNA | maturation protein S ingle-stranded (ss) RNA viruses are an abundant type of virus and infect all domains of life (1)(2)(3)(4). One of the beststudied ssRNA virus systems is the Leviviridae, which infects Gram-negative bacteria via a variety of retractile pili (5); extensive genetic and biochemical studies have been performed on two of these phages: MS2 and Qβ (5)(6)(7)(8)(9)(10)(11).…”

“…Анализ геномов различных вирусов други-ми авторами также показал, что между разными по своей природе вирусами происходила реком-бинация геномов [8,10,17]. Рекомбинировали между собой также РНК-и ДНК-содержащие вирусы.…”

“…Обнаружение ГП среди РНК-содержащих вирусов подтверждает существование в при-роде множественной глубокой рекомбинации среди вирусов [8,10,17], которая могла бы про-исходить при коинфицировании ими человека или в других общих для них хозяевах. Не следу-ет полагать, что наличие в геномах вирусов ГП обязательно отображается в гомологичные пеп-тидные последовательности тех белков вирусов, на гены которых приходятся соответствующие ГП, так как рамка считывания рекомбинирован-ных фрагментов может быть сдвинута на 1 или 2 нуклеотида и ГП в геноме могут соответство-вать совершенно несходные последовательности пептидных фрагментов.…”
