Adaptation of Archaeal Communities to Summer Hypoxia in the Sediment of Bohai Sea.

ABSTRACT: Understanding the adaptation of archaea to hypoxia is essential for deciphering the functions and mechanisms of microbes when suffering environmental changes. However, the dynamics and responses of archaea to the sedimentary hypoxia in Bohai Sea are still unclear. In this study, the diversity, composition, and distribution of archaeal community in sediment along an inshore-offshore transect across the oxygen-depleted area in the Bohai Sea were investigated in June, July, and August of 2021 by employing high-throughput sequencing of 16S rRNA gene. Results indicated that the archaeal communities were dominated by Thermoproteota (80.61%), Asgardarchaeota (8.70%), and Thermoplasmatota (5.27%). Dissolved oxygen (DO) and NO₃ ^- were the two key factors shaping the distributi
