Abstract

Family Smacoviridae (order Cremevirales, class Arfiviricetes, phylum Cressdnaviricota) comprises viruses with small circular genomes of ~2300-3000 nt in length that encode at least two proteins, the rolling-circle replication associated protein (Rep) and the capsid protein (CP). Smacovirids have been discovered in fecal samples of various animals and display remarkable sequence diversity. Here, we provide an overview of the genomic properties of classified smacovirids and report on the latest taxonomy update in the family Smacoviridae. The family has been expanded by 59 new species in the genera Porprismacovirus (n = 25), Inpeasmacovirus (n = 1), Felismacovirus (n = 22), Drosmacovirus (n = 4), Dragsmacovirus (n = 2), Bovismacovirus (n = 4), and Bonzesmacovirus (n = 1) and currently includes 12 genera with 143 species officially recognized by the International Committee on Taxonomy of Viruses (ICTV).

摘要

家族 Smacoviridae（Cremevirales 目，Arfiviricetes 纲，Cressdnaviricota 门）由具有约 2300-3000 个核苷酸长度的小圆形基因组的病毒组成，这些病毒至少编码两种蛋白质，即滚环复制相关蛋白 (Rep) 和衣壳蛋白 (CP)。Smacovirids 已在各种动物的粪便样本中被发现，并显示出显著的序列多样性。在这里，我们提供了分类的 Smacovirids 的基因组特性概述，并报告了家族 Smacoviridae 的最新分类学更新。该家族通过在属 Porprismacovirus（n = 25）、Inpeasmacovirus（n = 1）、Felismacovirus（n = 22）、Drosmacovirus（n = 4）、Dragsmacovirus（n = 2）、Bovismacovirus（n = 4）和 Bonzesmacovirus（n = 1）中增加了 59 个新种，目前包括 12 个属和 143 个种，这些种被国际病毒分类委员会（ICTV）正式认可。
