Abstract
Ethylene regulates several aspects of plant development, such as fruit ripening. In this issue of Genes & Development, Qiao and colleagues (pp. 512–521) report that the stability of the ethylene signaling protein EIN2 is modulated by two F-box proteins ETP1/2, reminiscent of the finding that another regulator of ethylene response, EIN3, is also targeted by the F-box proteins EBF1/2. ETP1/2 and EBF1/2 show distinct phylogenetic patterns, suggesting that they have different evolutionary constraints.
