Genomic evidence on the distribution and ecological function of Pseudomonas in hadal zone.

ABSTRACT: The hadal zone is the deepest region on Earth. It serves as a depositional zone for the sinking matter from surface ocean and continental margin, aided by its unique V-shaped structure. Due to extreme depth (over 6000 m), normally only organic matter with low degradability typically reaches the bottom of the trench. Concurrently, reports have indicated highly active carbon turnover and dense bacterial cells in the Mariana Trench. There remains a cognitive gap in understanding the connection between this phenomenon and the microbial taxa along with their metabolic activities. Here, we surveyed the Pseudomonas, one of the most widely distributed bacterial genera on Earth. The result revealed widespread distribution of Pseudomonas in the hadal zones. We obtained 21 metagenome-assembled genome
