Xiao, Yao Liu, Hao Wang, Pudi Zhang, Yue Wang, Fangzhou Jing, Hongmei Geologic Sediments Microbiota Seawater Bacteria Metagenome Water Microbiology Microbes are widespread from the marine surface to the hadal zones and play a significant role in global biogeochemical cycling. Physicochemical properties of hadal zone shift with depth, in turn influencing the distribution profiles, biogeochemical functions, and adaptative mechanisms of microbial communities in hadal trenches. However, the ecological functions and evolutions of microbial communities along the surface water down to the sediments in the Diamantina and Kermadec trenches have been rarely studied. Here, we provided a detailed metagenomic analysis of samples along the water columns (0-6553 m) and sediments (3060-9232 m) in the Diamantina and Kermadec trenches.

These findings provided new insights into the community succession and potential adaption mechanism along the water columns to sediments in deep trenches. |
