(Submitter supplied) To investigate how JA regulates Al-induced inhibition of root growth, a transcriptional analysis through RNAseq was performed by comparing the coi1-2 mutant and WT plants in the presence or absence of Al. In the absence of Al, 149 and 147 genes were up- and down-regulated, respectively, at least 2-fold in the roots of the coi1-2 mutant and WT plants. In the presence of Al, 1747 and 5838 genes were up- and down-regulated, respectively, in the roots of WT plants, while 1449 and 3773 genes were up- and down-regulated, respectively in the coi1-2 mutant. more...

(Submitter supplied) The plant hormone jasmonate (JA) plays important roles in the regulation of defense responses in many plants. To clarify the response to JA in rice at gene expression level, we performed a microarray analysis using the Agilent Rice Oligo Microarray (44k, custom-made; Agilent Technologies, Redwood City, CA, USA). As a result, treatment of JA caused high upregulation of many defense-related genes including pathogenesis-related (PR) genes in rice. 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) 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) 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) Next-generation sequencing (NGS) was used to analysis the expression profiling of cotton seedlings under TOR inhibition by AZD. TOR inhibition significantly altered the expression levels of anabolic and catabolic processes related genes, photosynthesis and phytohormone signaling pathways related genes. Expression profiling analysis reveals that TOR is a key player in cotton seedlings growth.

(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) 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) 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...
