Regulation of jasmonate-mediated plant responses in arabidopsis.

Jasmonates (JAs) are signalling molecules that play a key role in the regulation of metabolic processes, reproduction, and defence against pathogens and insects. JAs regulate responses that are both local and systemic, and which are affected by outputs from signalling pathways regulated by ethylene, salicylic acid and auxin. This is a review of recent advances in our understanding of the regulation of JA perception in Arabidopsis thaliana, the different signalling functions of biologically active JAs, the post-translational control of JA responses leading to substantial transcriptional reprogramming, and the influence of other signalling pathways of systemic JA responses.
