Epsilonproteobacteria bacterium SCGC AD-311-M19 Genome sequencing

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，探究水体缺氧程度变化过程中，微生物生理演替、生态型划分与分类群替代三者间的关联机制。样本采集自一项持续运行的时序监测项目，该项目针对季节性缺氧的沿岸、过渡带及开阔大洋氧气最低带（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氧气最低带。
