The R script used was deposited in GitHub (https://github.com/ying-wang09/mSystems20230106.git) We know little about the assembly processes and association patterns of microbial communities below the photic zone. In marine pelagic systems, there are insufficient observational data regarding why and how the microbial assemblies and associations vary from photic to aphotic zones. In this study, we investigated size-fractionated oceanic microbiotas, specifically free-living (FL; 0.22 to 3 μm) and particle-associated (PA; >3 μm) bacteria and protists (0.22 to 200 μm) collected from the surface to 2,000 m in the western Pacific Ocean, to see how assembly mechanisms and association patterns changed from photic to aphotic zones. Taxonomic analysis revealed a distinct community composition between photic and aphotic zones that was largely driven by biotic associations rather than abiotic factors. Aphotic community co-occurrence was less widespread and robust than its photic counterparts, and biotic associations were crucial in microbial co-occurrence, having a higher influence on photic than aphotic co-occurrences. The decrease in biotic associations and the increase in dispersal limitation from the photic to the aphotic zone affect the deterministic-stochastic balance, leading to a more stochastic-process-driven community assembly for all three microbial groups in the aphotic zone. Our findings significantly contribute to our understanding of how and why microbial assembly and co-occurrence vary from photic to aphotic zones, offering insight into the dynamics of the protistan-bacterial microbiota in the western Pacific’s photic and aphotic zones This work was supported by the National Natural Science Foundation of China (42130401, 42141002, 31772426, 42276095), the National Key Research and Development Program of China (2016YFA0601202), and the NSFC Ship Time Sharing Project (project number 41749909) With the institutional support of the ‘Severo Ochoa Centre of Excellence’ accreditation (CEX2019-000928-S) Peer reviewed 2023-12-21T11:08:35Z 2023-12-21T11:08:35Z 2023-03 artículo mSystems 8(2): e00013-23 (2023) CEX2019-000928-S http://hdl.handle.net/10261/341147 10.1128/msystems.00013-23 2379-5077 en https://doi.org/10.1128/msystems.00013-23 Sí open American Society for Microbiology |
