微生物驱动着无数的生态系统过程，而它们的病毒通过死亡率、水平基因转移和由病毒编码的辅助代谢基因（AMG）进行的代谢重编程来调节微生物驱动的过程。然而，我们对病毒在海洋中的作用的了解主要限于表面沃茨。在这里，我们评估的蛋白质簇（PC）的深度分布在第一个大规模的定量病毒宏基因组数据集，跨越了大部分的远洋深度连续体（太平洋病毒组; pacific Ocean Virome; pacific）。这建立了“核心”（180个PC;三分之一新的科学）和“灵活”（423 K PC）社区基因集，包括后者的生态位定义基因（385和170个PC是唯一的和核心的透光区和无光区，分别）。分类学注释表明，有尾两栖类是普遍存在的，但并不丰富（
Microbes drive myriad ecosystem processes, and their viruses modulate microbial-driven processes through mortality, horizontal gene transfer, and metabolic reprogramming by viral-encoded auxiliary metabolic genes (AMGs). However, our knowledge of viral roles in the oceans is primarily limited to surface waters. Here we assess the depth distribution of protein clusters (PCs) in the first large-scale quantitative viral metagenomic data set that spans much of the pelagic depth continuum (the Pacific Ocean Virome; POV). This established 'core' (180 PCs; one-third new to science) and 'flexible' (423K PCs) community gene sets, including niche-defining genes in the latter (385 and 170 PCs are exclusive and core to the photic and aphotic zones, respectively). Taxonomic annotation suggested that tailed phages are ubiquitous, but not abundant (
