The distribution of the phytohormone auxin regulates many aspects of plant development including growth response to gravity. Gravitropic root curvature involves coordinated and asymmetric cell elongation between the lower and upper side of the root, mediated by differential cellular auxin levels. The asymmetry in the auxin distribution is established and maintained by a spatio-temporal regulation of the PIN-FORMED (PIN) auxin transporter activity. We provide novel insights into the complex regul ...[more]

Microarray designed to find PIN polarity regulators downstream of TIR1/AFB

Project description:Roots of 5-day-old 35S::WRKY23-GR were treated for 6 hours with 10 μM DEX or DMSO, respectively. Wt Col-0 and 35S::WRKY23-SRDX plants were treated with 10 μM NAA or DMSO for 6 hours. Roots were subsequently collected for RNA isolation. All replicates were sampled in three independent experiments. Total RNA (200 μg per array) was hybridized to ATH1 Affymetrix Arabidopsis arrays in accordance with the standard procedures at the VIB Nucleomics Core. Data files containing probe level intensities (.cel files) were used for background correction and normalization was done in R (http://www.r-project.org) using the Bioconductor package affylmGUI (http://bioinf.wehi.edu.au/affylmGUI/) using the log2 scale RMA procedure. Genes with the same or contrasting WRKY23 expression profiles were selected by Pavlidis template matching in TMeV 4.0 (TIGR) (28). Finally, genes with a significant p value (< 0.001), denoting expression above background with minimum 2-fold change compared to the respective control, were retained for further analysis. First, by comparing 35S::WRKY23-GR roots with and without induction by dexamethasone, we obtained a set of 110 genes as potential WRKY23 targets, which were up-regulated in dexamethasone-treated seedlings. Next, we identified 950 genes, which were auxin-inducible in Col-0 wild type (Wt), but lost this auxin responsiveness in dominant-negative 35S::WRKY23-SRDX roots. The overlap between the two datasets yielded a list of 61 genes (Fig. S1B). Because WRKY23 acts downstream of the SLR/IAA14 transcriptional repressor, this genelist was compared with previously published microarray data on auxin-treated solitary root1 (slr-1) mutant seedlings

Transcriptome analysis of genes regulated by INDEHISCENT (IND) transcription factor under the control of the 35S promoter after treatment with auxin

Project description:IND is a regulator of fruit development in Arabidopsis thaliana. To identify genes regulated by IND we performed array based transcriptome analysis of Dexamethasone (DEX) inducible IND transgenic seedlings. One week old 35S::IND:GR seedlings were treated with DMSO, Auxin, DEX and Auxin plus DEX for 6 h. Three biological independent experiments were performed.

Proteomic data of MG132 treated A. thaliana WT and ppi2

Project description:A mutation in the proteasomal lid subunit Rpn8a alters proteasome composition and exerts a beneficial effect on photosynthesis. The effect is particularly visible in a double mutant between rpn8a and the plastid protein import receptor Toc159 (ppi2xrpn8a) but also in an rpn8a single mutant that shows higher PSII efficiency and lower non-photochemical quenching. The double mutant shows elevated accumulation of pigments, higher levels of thylakoid membrane proteins and higher PSII quantum yield compared to the ppi2 single mutant. While proplastid-like pro-thylakoid structures are characteristic for ppi2, stacked thylakoids are frequently observed in the double mutant. The rpn8a mutation is accompanied by higher 20S and lower 26S proteasome abundance and increased expression levels of proteolytic stress markers. Unlike known retrograde signaling chains, there is no effect on the transcription of selected photosynthesis associated nuclear encoded gens (PhanGs). Since plastid precursor protein abundance is elevated in the double mutant it is conceivable that the changes in proteasome composition affect precursor stability. We propose a model in which mild proteasome impairment shifts the equilibrium between precursor import and degradation towards import, which is especially effective in plastid protein import mutants but also detectable in the wildtype background, albeit to a much weaker extent.

Transcriptional profiles between mp mutant seedlings and transgenics carrying the dexamethasone-inducible GR-bdl protein

Project description:In order to identify targets of the transcription factor AUXIN RESPONSE FACTOR5 / MONOPTEROS (ARF5/MP), we compared transcriptomes of mp-B4149 mutant seedlings (9 day-old) and seedlings carrying the dexamethasone-inducible version of the MP inhibitor protein BODENLOS (GR-bdl). Without dexamethasone (DEX) treatment, this line is identical to the wild-type, while DEX treatment leads to strong inhibition of ARF-dependent transcription. To remove all endogenous MP-inhibiting Aux/IAA proteins, we treated mp or GR-bdl seedlings during 1 hour with auxin (50 micromolar Indole-3-Acetic Acid), either with or without a pretreatment with 10 micromolar DEX for 1 hour. Genes that are activated by MP are expected to br downregulated in mp seedlings and in the GR-bdl line afer DEX treatment. We used biological duplicates for each of the three treatments. Keywords: Transcriptional profiling of transcription factor targets Mp mutant and GR-bdl seeds were germinated on solid 1/2MS media, and transferred to liquid medium after 9 days of horizontal growth. Duplicate cultures were generated for mp mutants, and quadruplicates for the GR-bdl line. 10 micromolar DEX was added to both mp cultures and to two of the GR-bdl cultures, and seedlings were gently shaken during 1 hour. Then, 50 micromolar IAA was added to all 6 cultures and seedlings were incubated with gentle shaking for another hour. Total RNA was isolated from the seedlings using a QIAgen RNeasy kit, and reverse transcription, in-vitro transcription, cRNA labling and fragemntation was done according to established methods (Schmid et al., Nature Genetics [2005] 37, 501-506). Labeled cRNA was hybridized to Arabidopsis ATH1 arrays.

Expression data from Arabidopsis wild type and ibr1 ibr3 ibr10 triple mutant seedlings root tip segments treated with indole-3-butyric acid (IBA)

Project description:The root cap-specific conversion of the auxin precursor indole-3-butyric acid (IBA) into the main auxin indole-3-acetic acid (IAA) generates a local auxin source which subsequently modulates both the periodicity and intensity of auxin response oscillations in the root tip of Arabidopsis, and consequently fine-tunes the spatiotemporal patterning of lateral roots. To explore downstream components of this signaling process, we investigated the early transcriptional regulations happening in the root tip during IBA-to-IAA conversion in Col-0 and ibr1 ibr3 ibr10 triple mutant after 6 hours of IBA treatment. Arabidopsis thaliana (L). Heynh., Col-0 and ibr1ibr3ibr10 seeds were germinated vertically on solid medium derived from standard Murashige and Skoog (MS) medium. Three days after germination, Col-0 and ibr1ibr3ibr10 seedlings were transferred to a fresh MS medium supplemented with or without 10 ?M indole-3-buytric acid (IBA) for 6 hours. Then, root tip segments (~4mm) were dissected from the primary root and harvested for further RNA extraction. For each treatment, at least 120 individual Col-0 or ibr1ibr3ibr10 mutant root tip segments were sampled and three independent biological replicates were performed. Hormone and DMSO solution were filer-sterilized before being added to the medium.

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.
