title: JAZ repressors and the orchestration of phytohormone crosstalk.
abstract: The JAZ (JASMONATE-ZIM DOMAIN) family proteins act as jasmonate (JA) co-receptors and transcriptional repressors in JA signalling in Arabidopsis (Arabidopsis thaliana). Recently, identification of JAZ-interacting proteins regulating different aspects of the JA pathway has shown that JAZ repressors have overlapping, but finely separated functions in JA signalling. In addition, new insights into suppression mechanisms employed by JAZ proteins have been uncovered. Here we first briefly review these recent findings and then highlight newly identified roles for JAZ proteins in orchestrating the crosstalk between JA and other hormone signalling pathways such as ethylene, gibberellin, salicylic acid and auxin. The emerging roles that JAZ proteins play in the regulation of diverse phytohormone signalling interactions illustrate the functional versatility of this protein family.
