(Submitter supplied) Jasmonate (JA) is a plant hormone that controls trade-offs between plant growth and responses to biotic and abiotic stresses. Although recent studies uncover core mechanism for JA-induced responses in Arabidopsis thaliana, it remains elusive how plants attenuate those responses. We report here that a basic-helix-loop-helix type transcription factor named JA-INDUCIBLE MYC2-LIKE1 (JAM1) acts as a transcriptional repressor and negatively regulates JA signaling. more...

(Submitter supplied) We have used Agilent whole genome arrays (v4) to compare the gene expression changes between 5 days-old Arabidopsis ga1 mutants, pif1345 mutants (Leivar et al., 2008) and transgenic lines overexpressing the regulators GNC and GNL/CGA1 to the wild type. All mutants or transgenic lines are in the Columbia-0 background. Three independent biological samples were prepared for each genotype.

(Submitter supplied) Allantoin is a metabolic intermediate of purine catabolism that often accumulates in stressed plants. Recently, using Arabidopsis knockout mutants (aln) of ALLANTOINASE, we showed that this purine metabolite activates ABA production, thereby stimulating stress-related gene expression and enhancing seedling tolerance to abiotic stress. A detailed re-examination of the microarray data of an aln mutant (aln-1) not only confirmed increased expression of ABA-inducible genes, but also revealed altered expression of genes involved in jasmonic acid (JA) responses, likely under the control of MYC2, a master switch in the JA signaling pathway. more...

(Submitter supplied) Purine catabolism is regarded as a housekeeping function that remobilizes nitrogen for plant growth and development. However, emerging evidence suggests that certain purine metabolites might contribute to stress protection of plants. Here, we show that in Arabidopsis, the intermediary metabolite allantoin plays a role in abiotic stress tolerance via activation of abscisic acid (ABA) metabolism. The aln loss-of-function of ALN, encoding allantoinase, results in increased allantoin accumulation, genome-wide up-regulation of stress-related genes, and enhanced tolerance to drought-shock and osmotic stress in aln mutant seedlings. more...

(Submitter supplied) Submergence induces hypoxia in plants; exposure to oxygen following submergence, termed reoxygenation, produces a burst of reactive oxygen species. The mechanisms of hypoxia sensing and signaling in plants have been well studied, but how plants respond to reoxygenation remains unclear. Here, we show that reoxygenation in Arabidopsis thaliana involves rapid accumulation of jasmonates (JAs) and increased transcript levels of JA biosynthesis genes. more...

(Submitter supplied) Pathogens target phytohormone signalling pathways to promote disease. Plants deploy salicylic acid (SA) mediated defences against biotrophs. Pathogens antagonise SA immunity by activating jasmonate signalling, e.g. Pseudomonas syringae pv. tomato DC3000 produces coronatine (COR), a jasmonate (JA) mimic. This study found unexpected dynamics between SA, JA and COR and co-operation between JAZ jasmonate repressor proteins during DC3000 infection. more...

(Submitter supplied) The aim of this study is to identify early DELLA protein-responsive genes using a Dexamethasone (DEX)-inducible system. Two transgenic lines were used: one induces the expression of a dominant, gibberellin non-responsive DELLA protein (rga-delta17); the other is a control line that carries the same vector, but lacks the rga-delta17 transgene. By comparing the gene expression changes in the line that expresses the rga-delta17 protein in the presence or absence of DEX it is possible to identify putative targets of DELLA proteins. more...

(Submitter supplied) The aim is to identify early gibberellin responsive genes in a gibberellin deficient strain such as ga1-3. Such genes are likely regulated by DELLA proteins which are master gibberellin repressors. DELLA proteins are rapidly degraded after gibberellin treatment, but their direct target genes still need to be elucidated. Keywords: hormone response, gibberellin treatment

(Submitter supplied) Suppression mechanism employed by transcriptional repressors is commonly existed in diverse phytohormone signaling. In Arabidopsis thaliana, JASMONATE-ZIM DOMAIN (JAZ) proteins act as transcriptional repressors and involve in different aspects of the JA signaling network, through recruiting general co-repressors TOPLESS (TPL) and TPL-related proteins (TPRs). To accomplish overlapping but also finely separated functions of JAZ proteins, specificadaptor proteins are employed in JA signaling. more...
