Carbon assimilation rates. Net CO₂ uptake in TAP (A) and HS (B) media. Measurements of cells cultured at 160 μmol m⁻² s⁻¹ are indicated by empty diamonds, 40 μmol m⁻² s⁻¹ by empty squares, 15 μmol m⁻² s⁻¹ by empty triangles, 5 μmol m⁻² s⁻¹ by filled diamonds, and 0 μmol m⁻¹ s⁻¹ by filled squares. Acetate uptake in TAP cultures in C for N-replete cells (white), 0 to 24 h of N deprivation (gray), and 24 to 96 h of deprivation (black). Error bars indicate sd (n = 3).
