Genome-wide analysis of the auxin-responsive transcriptome downstream of iaa1 and its expression analysis reveal the diversity and complexity of auxin-regulated gene expression.

The AUXIN RESPONSE FACTORs (ARFs) and the Aux/IAA proteins regulate various auxin responses through auxin perception mediated by the F-box proteins TIR1/AFBs. ARFs are transcription factors that modulate expression of auxin response genes and are negatively regulated by the Aux/IAA proteins. To gain insight into the regulatory mechanisms of Aux/IAA-ARF action at the genome level, the transcriptome regulated downstream of iaa1, a stabilized IAA1 mutant protein, was identified using dexamethasone ...[more]

Transcription profiling of Arabidopsis ARF6 and ARF8 mutants treated with indoleacetic acid (IAA)

Project description:The aim of this study was to examine the roles of Auxin Response Factors (ARFs) in flower gene expression. Flowers from arf6 arf8 plants undergo a developmental arrest at approximately stage 12, just prior to flower opening. Wild-type, ARF6/arf6 arf8/arf8, and arf6 arf8 plants were treated with 10 uM indole-3-acetic acid for thirty minutes to identify genes that respond rapidly to auxin in an ARF6/ARF8-dependent manner. Experiment Overall Design: Wild-type, ARF6/arf6 arf8/arf8, and arf6 arf8 plants were sprayed with 10 mM indole-3-acetic acid in 1% methanol, 0.05% Tween-20. Thirty minutes after treatment, flowers (stage 1-14) were collected, frozen in liquid nitrogen, and used for RNA extraction.

Transcription profiling of Arabidopsis transgenic lines with a gibberellin non responsive DELLA protein vs control to identify DELLA protein direct targets

Project description: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. An empty vector transgenic line was included in this study to identify genes that might be regulated by the DEX inducible system that are not dependent on the DELLA protein. Experiment Overall Design: Seedlings of both transgenic lines were pretreated for 16 h with 2 uM GA4 to enhance gibberellin responses. Because DELLA proteins are strong signaling repressors, this pretreatment should maximize the effect of DELLA induction. Eight-day old seedlings were treated with 2 uM GA4 or a combination of 2 uM GA4 plus 10 uM DEX to induce the rga-delta17 transgene. Three biological replicas for the transgenic line that carries the DEX-inducible rga-delta17 transgene were generated at 2h and 4h. For the empty vector line, only 2 biological replicas were generated at 4h of treatment with 2 uM GA with or without 10 uM DEX.

indole-3-acetic acid (IAA) time course

Project description:Approximately 500 surface sterilized seeds of Arabidopsis seeds (ecotype: Col-0) were sterilely sown on filter disks overlaying solid ½ MS media 1% sucrose, stratified at 4C for 48 h and grown in darkness at 25C for 4 d. Seedlings were gently submerged by application to the plates of the different auxin solutions (made in ethanol carrier; 0.1% final concentration) and at the indicated times (20 min, 40 min, 60 min), the seedlings were lifted from the plate en mass and flash frozen in liquid nitrogen.

Transcription profiling of Arabidopsis sav mutants

Project description:Plants grown at high densities perceive a decrease in the red to far-red (R:FR) ratio of incoming light, resulting from absorption of red light by canopy leaves and reflection of far-red light from neighboring plants. These changes in light quality trigger a series of responses known collectively as the shade avoidance syndrome. During shade avoidance, stems elongate at the expense of leaf and storage organ expansion, there is reduced branching, and flowering is accelerated. We identified several loci in Arabidopsis, mutations in which lead to plants defective in multiple shade avoidance outputs. Here we describe SAV3, an aminotransferase, and show that SAV3 catalyzes the formation of indole-3-pyruvic acid (IPA) from L-tryptophan (L-Trp), the first step in a previously proposed, but uncharacterized, auxin biosynthetic pathway. This pathway can be rapidly deployed to biosynthesize auxin at the high levels required to initiate the multiple changes in body plan associated with shade avoidance. Experiment Overall Design: Wild type Col-0, sav3-2 and sav1-1 seedlings were used here. They were treated with or without 1hr of low R:FR light (R:FR ratio=0.7). Three independent biological replicates were used.

Transcription profiling of Arabidopsis seedlings treated with oligogalacturonides to assess how recognition of these compounds may contribute to defense against fungal pathogens

Project description:To assess the contribution to defenses against necrotrophic fungal pathogens that may be mediated by recognition of oligogalacturonides (OGs), cell wall fragments released by the activity of fungal polygalacturonases, we treated seedlings with OGs and assayed transcript levels 1 and 6 hours after addition of OGs to culture medium. For each sample, approximately 30 seedlings were grown in shallow liquid MS medium for 10 days. Plants were then treated with either 200 ug/ml OGs or, for control plants, an equal volume of water. Three replicate samples were assayed for each treatment.

The small signalling peptide CEP5 attenuates the dynamic AUX/IAA equilibrium

Project description:Root architecture is vital for plant growth and largely depends on primary root growth and lateral root development. Several plant hormones have been shown to affect root architecture among which auxin has been granted a central role. Lately, small signalling peptides also emerged as potential molecular components regulating root growth and development. Here, we identified C-TERMINALLY ENCODED PEPTIDE 5 (CEP5) as a novel, phloem poleexpressed paracrine signal for lateral root initiation. Our genetic, biochemical and pharmacological results show that CEP5 counteracts auxin signalling by stabilizing AUXIN/INDOLE ACETIC ACID (AUX/IAA) transcriptional repressors, suggesting the existence of an additional control mechanism through which plants can attenuate auxin signalling in a developmental context. Reducing CEP5 expression levels resulted in an increased auxin response and subsequently interfered with the normal progression through lateral root developmental stages.
