在这项研究中，我们提出了一个分析，从虹吸组织匀浆的滤液中获得的超基因组序列。从元基因组数据中挖掘病毒信号，鉴定出一种新的环状单链DNA病毒。基因组特征和系统发育分析表明，该病毒属于CressdNaviricota门，由单链环状DNA(SsDNA)基因组组成。这个门的成员已经在不同的物种和环境样本中被识别出来。新发现的病毒与目前已知的CressdNaviricota属成员有较远的亲缘关系。
In this study, we present an analysis of metagenome sequences obtained from a filtrate of a siphon tissue homogenate of otter clams (Lutraria rhynchaena) with swollen-siphon disease. The viral signal was mined from the metagenomic data, and a novel circular ssDNA virus was identified. Genomic features and phylogenetic analysis showed that the virus belongs to the phylumCressdnaviricota, which consists of viruses with circular, single-stranded DNA (ssDNA) genomes. Members of this phylum have been identified in various species and in environmental samples. The newly found virus is distantly related to the currently known members of the phylumCressdnaviricota.
