Overlapping and non-overlapping functions within the ethylene receptor family. (A) Roles of individual receptors in ethylene-regulated responses. A plus sign (+) indicates that the receptor activates the response, a negative sign (−) that the receptor inhibits the response and both signs (− +) that the receptor has differing effects dependent on other factors. The lack of a sign indicates that the receptor has no observed effect on the response. Differences in the box height indicate differences in receptor contribution to a particular response. (B) Details of interactions among receptors for selected ethylene responses. Differing thickness of arrows indicates differing contributions to a response.
