Clear niche partitioning of nitrite-oxidizing bacteria from the bottom and the slope of Mariana Trench
Our multiomics analysis revealed depth-dependent niche partitioning among hadal NOB, with transcriptional and network evidence supporting distinct pressure adaptation strategies and biogeochemical functions. The slope-bottom differentiation in stress response systems and nitrogen transformation pathways highlights how micron-scale environmental gradients drive microbial specialization in Earth's deepest ecosystems. These findings establish NOB as critical mediators of hadal biogeochemical cycles and provide a framework for understanding microbial resilience in extreme biospheres. Video Abstract.
