The MADS-domain transcription factor APETALA1 (AP1) is a key regulator of Arabidopsis flower development. To understand the molecular mechanisms underlying AP1 function, we identified its target genes during floral initiation using a combination of gene expression profiling and genome-wide binding studies. Many of its targets encode transcriptional regulators, including known floral repressors. The latter genes are down-regulated by AP1, suggesting that it initiates floral development by abrogat ...[more]

Project description:This experiment describes gene expression after the activation of APETALA1-GR, to study and identify AP1 target genes. We used a 35S:AP1-GR ap1 cal line to induce a synchronized response activating the AP1-GR fusion protein in ap1 cal inflorescence-like meristems through dexamethasone or dexamethasone+cycloheximide treatment. Tissue samples were collected at 3hrs after the treatment. The expression profiles of the individual samples were then analyzed by gene expression profiling using whole-genome oligonucleotide arrays (Agilent, custom-commercial). We treated inflorescences of 35S:AP1-GR ap1-1 cal-1 plants with a dexamethasone-containing or a mock solution, or with identical solutions that contained in addition 10 M-NM-<M cycloheximide. Tissue was collected 3 hours after the treatment. Samples from each of the four biological replicates resulted in a set of four hybridization pairs: Mock vs. Dex, Mock vs. Chx, Mock vs. Dex+Chx, and Chx vs. Dex+Chx. Dye polarities were switched between biological replicates.

We used a 35S:AP1-GR ap1 cal line to induce a synchronized response activating the AP1-GR fusion protein in ap1 cal inflorescence-like meristems through dexamethasone treatment. Tissue samples were collected immediately after the treatment, as well as subsequent timepoints. The expression profiles of the individual samples were then analyzed by gene expression profiling using whole-genome oligonucleotide arrays (non-commercial; Meyerowitz Lab Arabidopsis Operon Array v4). Keywords: time course Four sets of biologically independent tissue samples were collect at 0, 2, 4 ,8, and 12 hours after the application of dexamethasone (Dex-; activation of the AP1-GR fusion protein) or a mock solution (Mock-; control). In each of the biological replicates of the time course experiments, all the samples derived from dexamethasone (Dex)-treated plants were labeled with one dye (i.e., Cy3), and all the samples derived from the corresponding Mock-treated plants were labeled with the alternative dye (i.e., Cy5). The dyes used for labeling RNA from a given treatment type (Dex and Mock) were switched for two of the replicate experiments, to reduce dye-related artifacts. Dex- and Mock-derived samples for each timepoint and biological replicate were co-hybridized. This experimental setup resulted in a total of 5 hybridizations per set (0h, 2h, 4, 8h, and 12h; Dex vs. Mock at each timepoint), and two biological replicate sets labeled with each dye polarity (Mock-Cy3/Dex-Cy5, and vice versa). The combined ratio data results are available as a supplementary file on the Series record.

Project description:Plant inflorescence meristems and floral meristems possess specific boundary domains that result in floral organ separation, and in proper numbers of floral organs. HANABA TARANU (HAN) encodes a boundary-expressing GATA type zinc finger transcription factor that regulates shoot apical meristem organization, cell division and flower development in Arabidopsis, but the underlying mechanism remains unclear. Through time-course whole genome oligonucleotide microarray analyses following transient overexpression of HAN, we find that HAN represses hundreds of genes, especially genes involved in hormone responses and floral organ regulation. Transient overexpression of HAN also causes the repression of HAN itself and three other HAN family genes: HANL2 (HAN-LIKE2), GNC (GATA, NITRATE-INDUCIBLE, CARBON-METABOLISM-INVOLVED) and GNL (GNC LIKE), forming a negative regulatory feedback loop. Double- and triple-mutant strains of han with hanl2, gnc and gnl show synergistic effects on sepal fusion, petal number, and silique length, and embryo development, as well as carpelloid stamens. Transcripts of HANL2, GNC and GNL have similar accumulation patterns, specifically in petals, stamens, carpels and inflorescence meristems, which are partially overlapping with the expression pattern of HAN, suggesting that HAN and HAN family genes share redundant functions during flower development. We further show by yeast two hybrid assays that HAN can homodimerize as well as heterodimerize with other HAN family proteins. Chromatin-immunoprecipitation analyses indicate that HAN directly binds to its own promoter and the promoter of GNC in vivo. These findings, together with the fact that constitutive overexpression of HAN has an even stronger phenotype than a loss of function mutation, support the hypothesis that HAN may function as a key repressor that regulates floral development via intricate regulatory networks involving genes in the GATA3 family, hormone actions and floral organ specification. Time course induction experiment. Arabidopsis inflorescences containing flower buds from stages 1-9 were collected for microarray experiment 0h, 4h, 12h and 72h after 10M-BM-5M Dex treatment. RNA samples from mock- and Dex-treated plants at each time point were co-hybridized, and labeling dyes were swapped between replicates to reduce dye-related bias. Four biological replicates were used for the microarray hybridization.

Project description:This experiment describes gene expression after the activation of APETALA1-GR, to study and identify AP1 target genes. We used a pAP1:AP1-GR ap1 cal line to induce a synchronized response activating the AP1-GR fusion protein in ap1 cal inflorescence-like meristems through dexamethasone treatment. Tissue samples were collected immediately after the treatment, as well as subsequent timepoints. The expression profiles of the individual samples were then analyzed by gene expression profiling using whole-genome oligonucleotide arrays (Agilent, custom-commercial) Four sets of biologically independent tissue samples were collect before DEX-induction (day 0, 0d), as well as at 2 days, 4 days and 8 days after the treatment. Samples for each timepoint and biological replicate were co-hybridized as indicated; one sample was labeled with Cy3 and the other with Cy5. The dyes used for labeling RNA from a given timepoint were switched for two of the replicate experiments, to reduce dye-related artifacts. This experimental setup resulted in a total of 3 hybridizations per set (0days vs 2days, 2days vs 4days, and 4days vs 8days), and an even number (2) of hybridizations of each dye polarity per comparison.

Project description:Adults heterozygous for the hi2217 retroviral insertion within the HAI locus (Mathias et al 2007 JCS) were in-crossed for RNA from hi2217 mutants and corresponding WT siblings. Adults heterozygous for the hi1520 retroviral insertion within the Clint1 locus (Dodd et al, 2009) were in-crossed for RNA from hi1520 mutants and corresponding WT siblings. Both hi2217 and hi1520 are mutants with epidermal defects and showing symptoms of chronic inflammation. In this study we aimed to compare the RNA expression changes between Wild-type siblings (a non-inflammatory status) and homozygous mutants (a chronic inflammatory status) for each mutant background (hi2217 and hi1520). Pools of 30-50 zebrafish embryos of WT siblings and hi2217 or hi1520 mutants were collected for RNA isolation. RNA from the hi2217 mutant embryos or hi1520 mutant embryos (test samples)was labelled with Cy5 and hybridized against Cy3-labelled RNA from the corresponding WT sibling embryos (reference samples) . These experiments were performed in biological triplicate.

Project description:The Spi1/ Pu.1 transcription factor plays a crucial role in myeloid cell development across many species. Several Spi1 target genes have been identified so far, yet the Spi1-dependent gene group remains largely unknown. To identify novel genes downstream of Spi1 we employed a microarray strategy using zebrafish embryos. We established the gene group down-regulated upon spi1 knockdown while simultaneously enriched in FACS-sorted embryonic myeloid cells of a spi1:GFP transgenic line, thus representing putative myeloid-specific Spi1 target genes. This gene group contained all previously identified Spi1-dependent zebrafish genes, confirming the validity of the approach, as well as novel immune-related genes. Colocalization studies with neutrophil and macrophage markers revealed that genes cxcr3.2, mpeg1, ptpn6 and mfap4 were expressed specifically in early embryonic macrophages. The analysis of adult zebrafish hematopoietic tissue showed that genes mfap4 and mpeg1 remained macrophage specific within the myeloid fraction throughout zebrafish life. We also demonstrated that gene cxcr3.2, coding for chemokine receptor 3.2, functions in macrophage migration to the site of bacterial infection. These results establish a myeloid-specific gene group dependent on Spi1 in zebrafish and identify novel early macrophage-specific marker genes, which will facilitate further studies of macrophage development and innate immune function. Zebrafish strains Zebrafish (Danio rerio) were handled in compliance with the local animal welfare regulations and maintained according to standard protocols (http://ZFIN.org). The spi1-gfp transgenic line used in this study (Pu1-lynEGFP, a gift from Franscesca Peri, EMBL, Heidelberg) contains 4 kb of spi1/pu.1 promoter sequence driving expression of membrane-targeted EGFP. Morpholino knock-down experiments Morpholino oligonucleotides (Gene Tools) were diluted to required concentration in 1x Danieu’s buffer (58 mM NaCl, 0.7 mM KCl, 0.4 mM MgSO4, 0.6 mM Ca(NO3)2, 5.0 mM HEPES; pH 7.6) containing 1% Phenol red (Sigma) and approximately 1 nl was injected into the 1-2 cell stage embryo using a Femtojet injector (Eppendorf). Embryo dissociation and FACS (Fluorescent activated cell sorting) Dissociation of embryos was performed according to Covassin et al. 30. In short, ~300 embryos of spi1:GFP line at 28 hpf were dechorionated by pronase treatment, rinsed in calcium free Ringer solution, followed by digestion with 0.25% trypsin. The obtained cell suspension was centrifuged, rinsed with PBS and resuspended in Leibovitz medium L15 without phenol red, 1% fetal calf serum, 0.8mM CaCl2, penicillin 50 U/ml and streptomycin 0.05 mg/ml. The single cell suspension was subject to FACS at room temperature using a FACSAria (Becton Dickinson) with the BD FACSDiva software version 5.0.3 and a Coherent Sapphire solid state laser 488 nm with 13 mW power. The GFP+ and GFP- cell fractions were collected separately into L15 medium supplemented with 0.8 mM CaCl2, 10% fetal calf serum and penicillin 50 U/ml and streptomycin 0.05 mg/ml. The standard yield from circa 300 embryos was approximately 2 x 105 GFP+ cells. Microarray experiment design and analysis Embryos injected either with 1 mM Pu1 morpholino19 or 1 mM Standard Control morpholino were harvested at 28 hours post fertilization (hpf). As a control, embryos injected with an equal volume of 1% Phenol red in Danieu’s buffer (1xPR/D) were used. Pools of 20-30 embryos were collected. RNA samples from spi1 morphants and standard control morphants were labelled with Cy5 and hybridized against a Cy3-labelled common reference (a mixture of all samples injected with 1xPR/D). This experiment was performed in triplicate. FACS sorted spi1-GFP zebrafish embryos at 28hpf were analyzed as follows: the RNA of GFP-positive fraction was labelled with Cy5 and hybridized against a Cy3-labelled RNA of corresponding GFP-negative fraction of cells from the same pool of embryos. This experiment was performed in duplicate. RNA isolation, synthesis of amino allyl labeled aRNA, coupling of Cy3 and Cy5 dyes, and hybridization conditions were as described31. Microarray analysis was performed using custom-designed 44k Agilent chips (platform accession number in GEO: GPL7735) described elsewhere 31. Microarray data were processed and analyzed as described 31. Significance cut-offs for differentially expressed probe sequences were set at 1.2 fold change at P <10-2.
