Sponges are ecologically important components of marine and freshwater benthic environments; these holobionts contain a variety of microorganisms and viruses. For the metagenomic characterization of potential taxonomic and functional diversity of sponge-associated dsDNA viruses, we surveyed two samples of Baikal endemic sponge (diseased and visually healthy). In total, after quality processing, we have obtained 3 375 063 and 4 063 311 reads; of these 97 557 and 88 517 sequences, accounting for ca. 2.9 and 2.2% of datasets, have been identified as viral. We have revealed approximately 28 viral families, among which the bacteriophages of the , and families, as well as the viruses of the and families, dominated in the samples. Analysis of viral sequences using the COG database has indicated 22 functional categories of proteins. Viral communities of visually healthy and diseased Baikal sponges were significantly different. The metagenome sequence data were deposited to NCBI SRA as BioProject PRJNA577390.
海绵是海洋和淡水底栖环境中具有重要生态意义的组成部分；这些共生体包含多种微生物和病毒。为了对与海绵相关的双链DNA病毒的潜在分类学和功能多样性进行宏基因组学表征，我们调查了两个贝加尔湖特有海绵样本（患病的和外观健康的）。经过质量处理后，我们总共获得了3375063条和4063311条 reads；其中97557条和88517条序列被鉴定为病毒序列，分别约占数据集的2.9%和2.2%。我们发现了大约28个病毒科，其中 、 和 科的噬菌体以及 和 科的病毒在样本中占主导地位。使用COG数据库对病毒序列进行分析表明存在22种蛋白质功能类别。外观健康和患病的贝加尔湖海绵的病毒群落存在显著差异。宏基因组序列数据已作为生物项目PRJNA577390存入NCBI SRA。
