EIN3 is a key transcription factor in the ethylene signaling pathway in Arabidopsis and its action is controlled by SCFEBF1/2 complex-mediated ubiquitination and subsequent 26S proteasome-dependent degradation.

Jasmonates are important signaling molecules produced by plants which regulate in positive or negative crosstalk with ethylene subsets of genes involved in defense against necrotrophic microorganisms or herbivorous insects, respectively.
The bioactive jasmonate (+)-7-iso-JA-l-Ile promotes the interaction between the ubiquitin ligase complex SCF (COI1) and JAZ proteins, resulting in their degradation by the 26S proteasome, thereby liberating AtMYC2 from repression according to the prevailing model.

The data support the hypothesis that protein degradation via the ubiquitin/26S proteasome pathway is a control point of fruit ripening and open new leads for engineering fruit quality.
