Figure 3From: Comparative quantitative proteomics of prochlorococcus ecotypes to a decrease in environmental phosphate concentrationsRelative abundances of proteins associated with (A) nutrient acquisition and (B) central metabolism from MIT9312 (blue circles) and SS120 (black crosses). Dotted lines represent the abundance limits of 1.6 and 0.6. Error bars represent one standard error.Back to article page
