Figures

Figure 1.
Model for ethylene receptor action. A, In the absence of ethylene, receptors (AR) are actively suppressing ethylene responses such as fruit ripening. Upon ethylene binding, receptors become inactive (IR) and ethylene responses can proceed. Mutant receptors (M) cannot bind ethylene and continue to actively suppress downstream ethylene responses. B, Under normal circumstances, basal ethylene synthesis inactivates a small percentage of receptors (top). In loss-of-function mutants (bottom), the same amount of ethylene inactivates a much larger percentage of receptors, effectively lowering the threshold for initiating ethylene responses.

Schematic representation of the tomato ethylene receptor family. Black bars within the kinase domain indicate the presence of conserved His kinase elements. The His corresponding to the one phosphorylated in Arabidopsis ETR1 is indicated (H), where present.
