Identification of acyltransferases required for cutin biosynthesis and production of cutin with suberin-like monomers
TLDR
GPATs are identified as partners of fatty acyl oxidases in lipid polyester synthesis and indicate that their cooverexpression provides a strategy to probe the role of cutin composition and quantity in the function of plant cuticles. 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
Arabidopsis Genes Involved in Acyl Lipid Metabolism. A 2003 Census of the Candidates, a Study of the Distribution of Expressed Sequence Tags in Organs, and a Web-Based Database1
The genome of Arabidopsis has been searched for sequences of genes involved in acyl lipid metabolism. Over 600 encoded proteins have been identified, cataloged, and classified according to predictedExpand
Jasmonate signaling: a conserved mechanism of hormone sensing.
TLDR
These findings, together with homology between COI1 and the auxin receptor, TIR1, extend the paradigm of F-box proteins as intracellular sensors of small molecules, and suggest a common evolutionary origin of the Auxin and JA response pathways. Expand
A bHLH-Type Transcription Factor, ABA-INDUCIBLE BHLH-TYPE TRANSCRIPTION FACTOR/JA-ASSOCIATED MYC2-LIKE1, Acts as a Repressor to Negatively Regulate Jasmonate Signaling in Arabidopsis[C][W]
TLDR
Results indicate that JAM1 negatively regulates JA signaling, thereby playing a pivotal role in fine-tuning of JA-mediated stress responses and plant growth. Expand
Glutamate triggers long-distance, calcium-based plant defense signaling
TLDR
It is shown that glutamate is a wound signal in plants, which acts as sensors that convert this signal into an increase in intracellular calcium ion concentration that propagates to distant organs, where defense responses are then induced. Expand
Cytochrome P450 CYP94B3 mediates catabolism and inactivation of the plant hormone jasmonoyl-L-isoleucine
TLDR
It is demonstrated that CYP94B3 exerts negative feedback control on JA-Ile levels and performs a key role in attenuation of jasmonate responses, as well as in promoting the formation of COI1-JAZ receptor complexes. Expand
Modularity in Jasmonate Signaling for Multistress Resilience.
TLDR
This work reviews the jasmonate signaling pathway with an emphasis on understanding how transcriptional responses are specific, tunable, and evolvable and explores emerging evidence that JAZ proteins integrate multiple informational cues and mediate crosstalk by propagating changes in protein-protein interaction networks. Expand
Regulation and Function of Arabidopsis JASMONATE ZIM-Domain Genes in Response to Wounding and Herbivory1[W][OA]
TLDR
A role for JAZ proteins in the regulation of plant anti-insect defense is established, and the hypothesis that JA-Ile and perhaps other JA derivatives activate COI1-dependent wound responses in Arabidopsis is supported. Expand
Functional Diversification of Acyl-Coenzyme A Oxidases in Jasmonic Acid Biosynthesis and Action1[W][OA]
TLDR
It is indicated that ACX1/5-mediated JA synthesis is essential for resistance to chewing insects and male reproductive function and further suggest that other ACX isozymes contribute to JA production in response to A. brassicicola challenge. Expand
