species are essential benthonic animals in coastal ecosystems and have significant roles as live feed in aquaculture, owing to their high-protein and low-fat nutritional profile. Despite their ecological importance, the viral communities associated with these organisms need to be better understood. In this study, we generated 2.6 × 10 reads using meta-transcriptomic sequencing and assembled 5.3 × 10 virus-associated contigs. We identified 12 novel RNA viruses from two species, and , which were classified into four major viral groups: , , unclassified , and unclassified . Our findings revealed the hidden diversity of viruses and genome structures in , enriching the RNA virosphere and expanding the host range of , and . This study also highlighted the potential biosecurity risk of the novel viruses carried by to aquaculture.
[该物种]是沿海生态系统中的重要底栖动物，由于其高蛋白、低脂肪的营养特性，在水产养殖中作为活饲料发挥着重要作用。尽管它们具有生态重要性，但与这些生物相关的病毒群落仍需得到更好的了解。在本研究中，我们通过元转录组测序产生了2.6×10个读数，并组装了5.3×10个与病毒相关的重叠群。我们从两个物种[物种名1]和[物种名2]中鉴定出12种新型RNA病毒，它们被分为四个主要病毒组：[病毒组1]、[病毒组2]、未分类的[病毒组3]和未分类的[病毒组4]。我们的研究结果揭示了[物种名1]中病毒和基因组结构的隐藏多样性，丰富了RNA病毒圈，并扩大了[物种名1]和[物种名2]的宿主范围。这项研究还强调了[物种名1]携带的新型病毒对水产养殖的潜在生物安全风险。
