Figure 2From: Information flow during gene activation by signaling molecules: ethylene transduction in Arabidopsis cells as a study systemRelationship between the I ERF 1 function ( mers ) and the ethylene concentration ( μ L/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 μ L/L. The curve was calculated using equations (1) and (9).
