Abstract:
The Mininucleoviridae are crustacean-infecting viruses thought to drive mortality across aquatic biomes. Three have been characterised from Carcinus maenas, Panulirus argus, and Dikerogammarus haemobaphes. We screened 202 SRA datasets (NCBI) for novel mininucleoviruses from 44 amphipod species. Three metatranscriptome datasets from Gammarus lacustris contained sequences with similarity to Dikerogammarus haemobaphes mininucleovirus. Assembly resulted in 19 transcripts, 16 were putatively polycistronic. The putative Gammarus lacustris mininucleovirus shares 46 homologues with other mininucleoviruses (similarity range: 24.07 - 78.2 %). The transcripts from this putative virus highlight its likely association with the Mininucleoviridae.
摘要:
微小核病毒科是甲壳类动物感染病毒,被认为会导致水生生物群落的死亡。三个来自Carcinusmaenas,Panulirusargus,和Dikerogammarus血吸虫。我们从44种两栖动物物种中筛选了202种SRA数据集(NCBI)的新型微小核病毒。来自Gammaruslacustris的三个转移组数据集包含与Dikerogammarus血吸虫微小核病毒相似的序列。大会产生了19份成绩单,16个被推定为多顺反子。假定的Gammaruslacustris微小核病毒与其他微小核病毒共有46个同源物(相似性范围:24.07-78.2%)。来自该推定病毒的转录物突出了其与微小核病毒科的可能关联。
