微生物在海洋中占主导地位，但对其基因组变异性知之甚少，特别是沿着深度连续体。我们在这里报告的北太平洋亚热带环流，从海洋表面到近海底深度的浮游微生物群落的基因组分析。微生物群落基因的序列变异反映了分类群、功能基因库和代谢潜力的垂直地带性。微生物基因的分布模式表明，在碳和能量代谢，附着和运动，基因流动性，宿主-病毒相互作用的深度可变社区的趋势。分层的微生物群落的比较基因组分析有可能提供显着的洞察高阶社区组织和动态。
Microbial life predominates in the ocean, yet little is known about its genomic variability, especially along the depth continuum. We report here genomic analyses of planktonic microbial communities in the North Pacific Subtropical Gyre, from the ocean's surface to near-sea floor depths. Sequence variation in microbial community genes reflected vertical zonation of taxonomic groups, functional gene repertoires, and metabolic potential. The distributional patterns of microbial genes suggested depth-variable community trends in carbon and energy metabolism, attachment and motility, gene mobility, and host-viral interactions. Comparative genomic analyses of stratified microbial communities have the potential to provide significant insight into higher-order community organization and dynamics.
