Marine community metabolomes in the eastern tropical North Pacific Oxygen Deficient Zone reveal glycine betaine as a metabolic link between Prochlorococcus and SAR11

AbstractOxygen deficient zones (ODZs) are subsurface marine systems that harbor distinct microbial communities, including populations of the picocyanobacteria Prochlorococcus that can form a secondary chlorophyll maximum (SCM), and low-oxygen tolerant strains of the globally abundant heterotroph Pelagibacter (SAR11). Yet, the small labile molecules (metabolites) responsible for maintaining these ODZ communities are unknown.
