Patterns of interspecies transcriptional coordination are conserved across coastal and pelagic planktonic microbial communities. Correlated and anticorrelated functional pathways in the photoautotrophic and shared heterotrophic groups are shown for the California coast (CC, Upper Left) and North Pacific Subtropical Gyre (NPSG, Lower Right) metatranscriptomes. Pathway correlations were calculated from scaled adjacency matrixes by averaging across the correlations of the cognate transcripts (Methods). Pathways: 1: Transporters; 2: Translation; 3: Transcription: 4: Protein/RNA processing; 5: Oxidative phosphorylation; 6: Cofactor and vitamin metabolism; 7: Citrate cycle; 8: Amino acid metabolism; 9: Chemotaxis and flagellar assembly; 10: Central carbon metabolism; 11: Glycolysis; 12: DNA and chromosome processing.
