Understanding the mechanisms, structuring microbial communities in oligotrophic ocean surface waters remains a major ecological endeavor. Functional redundancy and metabolic tuning are two mechanisms that have been proposed to shape response environmental forcing. However, little is known about their roles due less integrative characterization of community taxonomy function. Here, we applied an integrated meta-omics-based approach, from genes proteins, investigate northern Indian Ocean. Insignificant spatial variabilities both genomic proteomic compositions indicated stable was dominated by Prochlorococcus, Synechococcus, SAR11. fine some functions mainly driven salinity temperature observed. Intriguingly, divergence occurred between potential activity different perturbations. Our results indicate important mechanism for sustaining stability oceans. In addition, meta-omics provides powerful tool comprehensively understand behavior function ocean.The online version contains supplementary material available at 10.1007/s42995-021-00119-6.
