Stabilization or degradation?Post-translational modifications of JAZ proteins in plants

Jasmonates(JAs)are essential hormones that regulate plant responses to biotic and abiotic stresses and are involved in various developmental processes,including flowering time control,floral organ development,and fertility of male and female gametes(Howe et al.,2018).However,our understanding of the mechanisms by which JAs integrate multiple signals to regulate diverse physiological processes remains *** the canonical JA signaling pathway,activated JAs are perceived by the F-box protein receptor CORONATINE INSENSITIVE 1(COl1),which induces the interaction between COl1 and the Jas domain of the repressor proteins JASMONATE-ZIM DOMAIN PROTEINs(JAZs),leading to the ubiquitination and degradation of JAZ *** proteolytic destruction of the JAZ repressors is a crucial step that releases the inhibition of JAZs on the JA response transcription factor MYC2,allowing MYC2 to activate the expression of downstream genes(Howe et al.,2018).Therefore,the stability and specific spatiotemporal expression pattern of the JAZ proteins are critical for the regulation of JA signaling output,as they determine the activation and repression of JA responses.
