摘要

南极海蜘蛛（Pentanymphon antarcticum）是南大洋中的一种底栖物种，但人们对其病原体特征知之甚少。在本研究中，我们提供了利用元基因组技术鉴定出的一种新的虹彩病毒的基因组草案。基因组草案总长 157260 bp，编码 188 个蛋白编码基因。该病毒与来自深海海绵宿主的 "肉食性海绵相关虹彩病毒 "的蛋白质相似度最高。这项研究首次发现了虹彩病毒，也是南极地区首次发现虹彩病毒。

An iridovirus from the Antarctic seaspider Pentanymphon antarcticum (Pycnogonida)

The Antarctic seaspider Pentanymphon antarcticum is a benthic species in the Southern Ocean, but little is known about its pathogen profile. In this study, we provide a draft genome for a new iridovirus species that has been identified using metagenomic techniques. The draft genome totals 157 260 bp and encodes 188 protein-coding genes. The virus shows greatest protein similarity to a ‘carnivorous sponge-associated iridovirus’ from a deep-sea sponge host. This study represents the first discovery of a pycnogonid iridovirus and the first iridovirus from the Antarctic region.

期刊介绍： Antarctic Science provides a truly international forum for the broad spread of studies that increasingly characterise scientific research in the Antarctic. Whilst emphasising interdisciplinary work, the journal publishes papers from environmental management to biodiversity, from volcanoes to icebergs, and from oceanography to the upper atmosphere. No other journal covers such a wide range of Antarctic scientific studies. The journal attracts papers from all countries currently undertaking Antarctic research. It publishes both review and data papers with no limits on length, two-page short notes on technical developments and recent discoveries, and book reviews. These, together with an editorial discussing broader aspects of science, provide a rich and varied mixture of items to interest researchers in all areas of science. There are no page charges, or charges for colour, to authors publishing in the Journal. One issue each year is normally devoted to a specific theme or papers from a major meeting.
