Metabolite production is not identical among PR:PROJECT_SUMMARY phytoplankton, and the flux of these molecules through the microbial loop PR:PROJECT_SUMMARY depends on compound-specific bioavailability to a wider microbial community. Yet PR:PROJECT_SUMMARY relatively little is known about the diversity or concentration of polar PR:PROJECT_SUMMARY metabolites within marine plankton. Here we evaluate 313 metabolites in 21 PR:PROJECT_SUMMARY phytoplankton species and in natural marine particles across environmental PR:PROJECT_SUMMARY gradients to show that bulk community metabolomes reflect the phytoplankton PR:PROJECT_SUMMARY community on a chemical level.

Samples were flash frozen in liquid N2 and CO:COLLECTION_SUMMARY stored at -80°C until extraction for metabolites. CO:SAMPLE_TYPE Cultured plankton cells CO:STORAGE_CONDITIONS Described in summary #TREATMENT TR:TREATMENT_SUMMARY Media, light, and temperature were chosen for optimal growth of each TR:TREATMENT_SUMMARY phytoplankton species. In short, axenic phytoplankton were cultured in TR:TREATMENT_SUMMARY controlled laboratory settings and harvested under exponential growth using a TR:TREATMENT_SUMMARY gentle vacuum filtration onto 47 mm Durapore filters (pore size 0.2 µm). TR:TREATMENT_SUMMARY Samples were flash frozen in liquid N2 and stored at -80°C until extraction. In TR:TREATMENT_SUMMARY addition to samples, media blanks corresponding to each media type were TR:TREATMENT_SUMMARY harvested and served as a matrix blank to each corresponding phytoplankton TR:TREATMENT_SUMMARY sample. #SAMPLEPREP SP:SAMPLEPREP_SUMMARY Each sample was extracted using a modified Bligh-Dyer extraction. Briefly, SP:SAMPLEPREP_SUMMARY filters were cut up and put into 15 mL teflon centrifuge tubes containing a SP:SAMPLEPREP_SUMMARY mixture of 100 µm and 400 µm silica beads. Heavy isotope-labeled internal SP:SAMPLEPREP_SUMMARY standards were added along with ~2 mL of cold aqueous solvent (50:50 SP:SAMPLEPREP_SUMMARY methanol:water) and ~3 mL of cold organic solvent (dichloromethane). The samples SP:SAMPLEPREP_SUMMARY were shaken on a FastPrep-24 Homogenizer for 30 seconds and chilled in a -20°C SP:SAMPLEPREP_SUMMARY freezer repeatedly for three cycles of bead-beating and a total of 30 minutes of SP:SAMPLEPREP_SUMMARY chilling. The organic and aqueous layers were separated by spinning samples in a SP:SAMPLEPREP_SUMMARY centrifuge at 4,300 rpm for 2 minutes at 4°C. The aqueous layer was removed to SP:SAMPLEPREP_SUMMARY a new glass centrifuge tube. The remaining organic fraction was rinsed three SP:SAMPLEPREP_SUMMARY more times with additions of 1 to 2 mL of cold 50:50 methanol:water. All aqueous SP:SAMPLEPREP_SUMMARY rinses were combined for each sample and ~2mL of cold dichloromethane was added SP:SAMPLEPREP_SUMMARY to the combined aqueous layer. Tubes were shaken and centrifuged at 4,300 rpm SP:SAMPLEPREP_SUMMARY for 2 minutes at 4°C. The aqueous layer was removed to a new glass vial and SP:SAMPLEPREP_SUMMARY dried under N2 gas. The remaining organic layer in the bead beating tubes was SP:SAMPLEPREP_SUMMARY transferred into the glass centrifuge tube and the bead beating tube was rinsed SP:SAMPLEPREP_SUMMARY two more times with cold organic solvent. The combined organic rinses were SP:SAMPLEPREP_SUMMARY centrifuged, transferred to a new glass vial, and dried under N2 gas. Dried SP:SAMPLEPREP_SUMMARY aqueous fractions were re-dissolved in 380 µL of water. Dried organic fractions SP:SAMPLEPREP_SUMMARY were re-dissolved in 380 µL of 1:1 water:acetonitrile. 20 µL of SP:SAMPLEPREP_SUMMARY isotope-labeled injection standards in water were added to both fractions. Media SP:SAMPLEPREP_SUMMARY blanks were extracted alongside samples as methodological blanks.
