Abstract

Advances in sequencing technologies and bioinformatics have led to breakthroughs in the study of virus biodiversity. Millipedes (Diplopoda, Myriapoda, Arthropoda) include more than 12,000 extant species, yet data on virus diversity in Diplopoda are scarce. This study aimed to explore the virome of the millipedes collected in the Dong Nai Biosphere Reserve in Vietnam. We studied 14 species of millipedes and managed to assemble and annotate the complete coding genomes of 16 novel viruses, the partial coding genomes of 10 more viruses, and several fragmented viral sequences, which may indicate the presence of about 54 more viruses in the studied samples. Among the complete and partial genomes, 27% were putative members of the order Picornavirales. Most of the discovered viruses were very distant from the viruses currently present in the relevant databases. At least eight viruses meet the criteria to be recognized as a new species by the International Committee on Taxonomy of Viruses, and, for two of them, a higher taxonomic status (genus and even family) can be suggested.

越南同奈生物圈保护区采集的千足虫体内病毒的广泛多样性。

测序技术和生物信息学的进步使病毒生物多样性研究取得了突破性进展。千足类（双足纲、绵足纲、节肢动物门）包括 12,000 多个现存物种，但有关双足类病毒多样性的数据却很少。本研究旨在探索在越南同奈生物圈保护区采集的千足类的病毒组。我们研究了 14 种千足虫，并成功地组装和注释了 16 种新型病毒的完整编码基因组、另外 10 种病毒的部分编码基因组以及一些片段病毒序列，这可能表明研究样本中还存在大约 54 种病毒。在完整基因组和部分基因组中，27%是短小病毒目（Picornavirales）的假定成员。大多数被发现的病毒与目前相关数据库中的病毒相去甚远。至少有八种病毒符合国际病毒分类委员会认定为新种的标准，其中两种病毒的分类地位更高（属甚至科）。

期刊介绍： Viruses (ISSN 1999-4915) is an open access journal which provides an advanced forum for studies of viruses. It publishes reviews, regular research papers, communications, conference reports and short notes. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. We also encourage the publication of timely reviews and commentaries on topics of interest to the virology community and feature highlights from the virology literature in the ''News and Views'' section. Electronic files or software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
