OM43 strain NB0046 transcription patterns and cell growth assays reveal similar responses to the vitamin (+MeOH +N +V) and HMW DOM (+DOM +N −V) regimes. (A) Hierarchical clustering (with Pearson correlation coefficients and complete linkage) of genome-wide transcript abundances. (B) Maximum NB0046 cell densities in UV-oxidized seawater medium with or without AMS1 vitamin mixture amendment after 72 h of incubation. Error bars are the SDs of biological triplicates. No C Amd., non-carbon-amended control.
