Figure 1.

Cell counts of dinoflagellates (diamonds), diatoms (triangles), and bacteria (circles) as determined by flow cytometry. For phytoplankton, the gray diamonds and triangles correspond to the cell counts measured in no-bacteria controls. For bacteria, gray inner circles indicate RNAseq sample collection. Arrows identify the two time points tested for differential expression comparisons. Asterisks indicate significant differences in phytoplankton cell numbers between co-cultures and no-bacteria controls. Mean value±s.d. for the triplicate cultures are shown.
