Relationship between the IERF1 function (mers) and the ethylene concentration (μL/L) in the root cells of Arabidopsis thaliana. An asymmetric potential-like curve is clearly observed, with a minimum located at an ethylene concentration of ~0.5 μL/L. The curve was calculated using equations (1) and (9). Also see Table 1.
