The lipid-derived hormone jasmonate (JA) regulates diverse aspects of plant immunity and development. Among the central components of the JA signaling cascade are the E3 ubiquitin ligase SCFCOI1 and Jasmonate ZIM-domain (JAZ) proteins that repress transcription of JA-responsive genes. Recent studies provide evidence that amino acid-conjugated forms of JA initiate signal transduction upon formation of a coronatine-insensitive1 (COI1)-JA-JAZ ternary complex in which JAZs are ubiquitinated and… Expand
The JAZ Proteins: A Crucial Interface in the Jasmonate Signaling Cascade
TLDR
Recent studies on the model plant Arabidopsis thaliana that provided essential and novel insights into JAZ proteins showed the value of protein–protein interaction studies to acquire fundamental insight into molecular signaling pathways. Expand

The oxylipin jasmonate (JA) regulates many aspects of growth, development, and environmental responses in plants, particularly defense responses against herbivores and necrotrophic pathogens. MutantsExpand
Jasmonates: structural requirements for lipid-derived signals active in plant stress responses and development.
TLDR
The emerging picture of JA perception and signaling cascade implies the SCF(COI1) complex operating as E3 ubiquitin ligase that upon binding of JA-Ile targets JAZ repressors for degradation by the 26S-proteasome pathway, thereby allowing the transcription factor MYC2 to activate gene expression.

Transcriptional regulation of plant inducible defenses against herbivores: a mini-review
TLDR
This review focuses on MyC2 and a specific group of MYC2-regulated ‘secondary’ transcription factors as critical components of the JA signal transduction pathway that controls inducible chemical defense responses in plants. Expand
Jasmonate-Triggered Plant Immunity
TLDR
The efficacy of JATI as a defense strategy is highlighted by its capacity to shape natural populations of plant attackers, as well as the propensity of plant-associated organisms to subvert or otherwise manipulate JA signaling. Expand

FILAMENTOUS FLOWER Is a Direct Target of JAZ3 and Modulates Responses to Jasmonate
TLDR
YAB transcription factors interact with JAZ3 and are required for JA-mediated responses, such as anthocyanin accumulation, chlorophyll loss, and susceptibility to Pseudomonas syringae DC3000 infection, to better understand how the JA-signaling pathway modulates and integrates different responses. Expand
A rapid wound signal activates the systemic synthesis of bioactive jasmonates in Arabidopsis.
TLDR
Wound-induced systemic production of JA-Ile required the JA biosynthetic enzyme 12-oxo-phytodienoic acid (OPDA) reductase 3 (OPR3) in undamaged responding leaves, but not in wounded leaves, and was largely dependent on the JA-conjugating enzyme JAR1. Expand
Identification of novel regulatory mechanisms involved in plant-herbivore interactions in Nicotiana attenuata
TLDR
Two novel regulatory mechanisms that regulate herbivore-induced plant defense responses in N. attenuata are reported, which signify the importance of this regulatory mechanism in plant defense regulation. Expand
The jasmonate pathway: the ligand, the receptor and the core signalling module.
TLDR
Small changes in jasmonate structure result in hormone inactivation and might be the key to switching-off signalling for specific responses to stimulus and for long-distance signalling events. Expand
