Figure 3: The Cumulative Factor model captures the linear increase in upregulated expressions and the Michaelis-Menten decrease in downregulated expressions.

. Best-fit regressions to the data using the equations in the text. The average value of the percentage change in $\text{cpm}$ across all genes in each subset is plotted in blue. Plot A models the sensory genes with an $R^2$ of 0.9999 and plot B models the growth genes with an $R^2$ of 0.9964.
