JAZ repressor proteins are targets of the SCFCOI1 complex during jasmonate signalling

Members of the jasmonate ZIM-domain (JAZ) protein family are identified as key regulators of jasmonate signalling. Some of these function as repressors of jasmonate-responsive gene expression. The results suggest a model in which jasmonate ligands promote binding of the SCFCOI1 ubiquitin ligase complex to jasmonate repressors, resulting in their degradation.
