Transcriptional and Proteomic Choreography Under Phosphorus Deficiency and Re-supply in the N₂ Fixing Cyanobacterium Trichodesmium erythraeum.

ABSTRACT: The N₂ fixing cyanobacterium Trichodesmium is a critically important organism in oligotrophic marine ecosystems, supplying "new" nitrogen (N) to the otherwise N-poor tropical and subtropical regions where it occurs. Low concentrations of phosphorus (P) in these regions can constrain Trichodesmium distribution and N₂ fixation rates. Physiological characterization of a single species in a mixed community can be challenging, and 'omic approaches are increasingly important tools for tracking nutritional physiology in a taxon-specific manner. As such, studies examining the dynamics of gene and protein markers of physiology (e.g., nutrient stress) are critical for the application and interpretation of such 'omic data in situ. Here we leveraged combined
