Epsilonproteobacteria bacterium SCGC AD-308-B14 Genome sequencing. Epsilonproteobacteria bacterium SCGC AD-308-B14

Single-cell genome sequencing to explore relationships between physiological succession, ecotype partitioning, and taxonomic replacement under changing levels of water column O2-deficiency. Samples were taken from an ongoing time-series program monitoring microbial community responses in seasonally anoxic coastal, transition, and open-ocean OMZs (oxygen minimum zones). The focus will be on samples from the northeastern subarctic Pacific Ocean (NESAP), which contains the largest and least-studied permanent OMZ in the global ocean.

本研究采用单细胞基因组测序技术，旨在解析水柱缺氧程度变化过程中，生理演替、生态型分化与分类群替代之间的内在关联。样本取自一项持续进行的时序监测项目，该项目针对季节性缺氧的近岸、过渡带及远洋含氧最低区（oxygen minimum zones, OMZs）内的微生物群落响应开展监测。本研究的重点样本取自东北亚北极太平洋（northeastern subarctic Pacific Ocean, NESAP），该区域拥有全球海洋中规模最大且研究程度最低的永久性含氧最低区。
