Guaymas Basin Sediment Metagenomic assembly

Deep-sea hydrothermal vents are hotspots for productivity and biodiversity. Thermal pyrolysis and circulation produce fluids rich in hydrocarbons and reduced compounds that stimulate microbial activity in surrounding sediments. Studies have characterized the diversity of Guaymas Basin (Gulf of California) sediment-inhabiting microorganisms, and many taxa were distinct from those whose physiologies have been described. Here, we resolved the metabolic potential and community-level interactions of these diverse communities. Therefore, we performed metagenomic sequencing of Guaymas Basin sediment samples and further reconstructed microbial genomes from the generated sequencing data.

深海热液喷口（Deep-sea hydrothermal vents）是海洋生产力与生物多样性的热点区域。热裂解与流体循环会产生富含烃类与还原性化合物的流体，进而刺激周边沉积物内的微生物活性。已有研究对栖息于瓜伊马斯盆地（Guaymas Basin，加利福尼亚湾）沉积物内的微生物多样性开展了表征，发现其中多数类群与现有文献中已报道生理特性的类群存在显著差异。本研究解析了这类多样微生物群落的代谢潜能与群落级互作关系。因此，我们对瓜伊马斯盆地的沉积物样本进行了宏基因组（metagenomic）测序，并基于所得测序数据进一步重构了微生物基因组。
