Fig 5. Agreement between RNA-seq data and predicted fluxes.

(a) Contribution of each segment to the objective function (Eq (3), excluding costs associated with scale factors). (b) Cumulative histogram of Pearson correlations between data and predicted fluxes for all reactions. (c) Predicted fluxes versus expression data at the tip of the leaf (blue, raw fluxes; red, after rescaling each flux v_i by the optimal factor $e^{s_i}$ of Eq (3)). Some outliers with very low predicted flux are not shown. (d) Relationship between RNA-seq and proteomics measurements for 506 proteins in the 14th segment from the base, redrawn from the data of [40]. NSAF, normalized spectral abundance factor.
