(Submitter supplied) Jasmonates are fatty acid derived hormones that regulate multiple aspects of plant development, growth and stress responses. Bioactive jasmonates differ between vascular plants and bryophytes (using jasmonoyl-L-isoleucine; JA-Ile and dinor-12-oxo-10,15(Z)-phytodienoic acid; dn-OPDA, respectively), but bind an evolutionarily conserved COI1 receptor. Whilst the biosynthetic pathways of JA-Ile in the model vascular plant Arabidopsis thaliana have been elucidated, the details of dn-OPDA biosynthesis in bryophytes are still unclear. more...

(Submitter supplied) JAZ genes are negative regulators of jasmonate responses with a dual function as repressors of transcription factors and co-receptors, together with COI1, of the hormone jasmonoyl-isoleucine (JA-Ile). This family has been mainly studied in angiosperms, where high gene redundancy hinders the characterization of a complete depletion of JAZ function. Moreover, the recent discovery that JA-Ile is not the sole COI1/JAZ ligand in land plants, as dn-OPDA is the bioactive ligand in Marchantia polymorpha, underscores the importance of studying JAZ co-receptors in bryophytes. more...

(Submitter supplied) The phytohormone (+)-7-iso-jasmonoyl-L-isoleucine (JA-Ile) is a major regulator of developmental and stress responses in plants. The perception of JA-Ile involves the formation of a ternary complex with the F-box protein COI1 and a member of the JAZ family of co-repressors, which leads to JAZ degradation. Coronatine (COR) is a bacterial phytotoxin that functionally mimics JA-Ile and interacts with the co-receptor COI1-JAZ complex with higher affinity than JA-Ile. more...

(Submitter supplied) The deficiency of Jasmonic Acid Oxidase 2 (JAO2) disrupts a metabolic sink in jasmonate hormonal pathway. Consequently, higher flux towards hormone JA-Ile is observed and some leaf JA responses have elevated basal levels relative to wild-type (WT) leaves. We report the compared transcriptomes of WT and jao2-1 rosette leaves, before and 48h after inoculation with spores of the fungus Botrytis cinerea. more...

(Submitter supplied) JASMONATE-ZIM DOMAIN (JAZ) proteins are key regulators in the JA signaling pathway and function to repress the expression of JA-responsive genes. We found that JAZ proteins directly interact with several chromatin-associated Polycomb proteins to mediate repressive chromatin modifications at part of JA-responsive genes and thus their transcriptional repression in Arabidopsis.

(Submitter supplied) Purpose: In this study we investigated the role of JASMONATE RESISTANT 1 (JAR1) and JAR1 mediated JA-Ile formation in drought stress tolerance in Arabidopsis thaliana. Methods: Global transcriptional changes in a newly generated over-expression line (JAR1-OE; 35S::JAR1-1-YFP)), a T-DNA insertion line in the JAR1 locus (jar1-11;SALK_034543), and wild-type Col-0 were investigated by RNA-seq analyses of rosette leaves from 32 day-old plant that were either well-watered (control) or not watered after day 18 (drought). more...

(Submitter supplied) The decuple jaz mutation (jazD) affects plant growth and defense. We used RNA-sequencing to query the transcriptomes of a jaz quintuple mutant (jazQ) and jazD, and examined how these mutations alter the expression of growth- and defense-associated genes in comparison to wild-type Col-0 plants. The data highlight how jasmonate pathways contribute to growth and defense.

(Submitter supplied) NINJA (At4g28910) and TOPLESS proteins function as negative regulators of jasmonate responses. Our results point to TPL proteins as general co-repressors that affect multiple signalling pathways through the interaction with specific adaptor proteins. This new insight reveals how stress- and growth-related signalling cascades use common molecular mechanisms to regulate gene expression in plants.

(Submitter supplied) Photoperiodic floral initiation in the leaf is controlled by the hub gene CONSTANS (CO) while jasmonates (JAs) control flower senescence. Although both processes are chronologically ordered, no association between them has been described to date. We show that CO protein remains in Arabidopsis flowers after the floral induction, although displaying a different tissue and diurnal pattern than in leaves. more...

(Submitter supplied) Jasmonates is inductively produced as a major plant hormone responsible for defense reactions in plants against both biotic and abiotic stresses, such as pathogen infection and mechanical wounding. Jasmonoyl isoleucine is known to be a bioactive compound of jasmonate and plays a pivotal role for plant defenses. We identified OsJAR1−related JA-inducible genes in osjar1 tos17 mutant (osjar1-2) rice leaves 0 - 2 h after JA treatment using 44k microarray.
