Role of JAZ Proteins in the Regulation of Jasmonate Signaling in Arabidopsis

In general, the steps in jasmonate (JA) signaling mirror that of auxin signaling: the first step comprises E3 ubiquitin ligase complexes, which tag substrates with ubiquitin to mark them for degradation proteasomes. The second step utilizes transcription factors to This study investigated the components of the JA signaling pathway in its response to dehydration stress. Coi1-2, 35S pro:JAZ1-ΔJas and myc2-2 mutants disrupted in key regulators of JA signaling were more sensitive to dehydration stress. This suggests that JA signaling plays a key role Within the signaling cascades that are triggered jasmonates, the JASMONATE-ZIM DOMAIN (JAZ) repressor proteins play a central role. JAZ proteins have been demonstrated to interact with a broad array of transcription factors that each control specific downstream processes.

Jasmonate-Regulated Processes in Flower Development Are Very The Arabidopsis Jasmonate ZIM-domain proteins (JAZs) act as substrates of SCFCOI1 complex to repress their downstream targets, which are essential for JA-regulated plant development and defense. The bHLH transcription factor MYC2 was found to interact with JAZs and mediate JA responses including JA-inhibitory root growth.

Jasmonate and related signalling compounds have a crucial role in both host immunity and development in plants, but the molecular details of the signalling mechanism are poorly understood. Here we identify members of the jasmonate ZIM-domain (JAZ) protein family as key regulators of jasmonate signaling cascades that are triggered jasmonates, the JASMONATE-ZIM DOMAIN (JAZ) specificity, function, and regulation of the different JAZ proteins.

JASMONATE ZIM-DOMAIN (JAZ) proteins as central components in the perception. It is now well established that jasmonates, originally identified as the major component of jasmine scent, play a universal role in the plant kingdom and are involved in the regulation of diverse aspects of plant biology, including growth, development, metabolism, and interaction with the environment. Jasmonate (JA) and its derivatives are lipid-based plant hormones that regulate a wide range In general, the steps in jasmonate (JA) signaling mirror that of auxin In the absence of JA, JAZ proteins bind to downstream transcription factors and JAs' roles in these processes are suggestive of methods which the plant The JAZ family of repressors is the missing link in jasmonate signalling.
