Transcript profiling of swp73b-1 Arabidopsis thaliana

ABSTRACT: SWP73 subunits of SWI/SNF chromatin remodeling complexes (CRCs) are involved in key developmental pathways in Arabidopsis. We found, using microarray that inactivation of SWP73B caused altered expression of genes belonging to various regulatory pathways, including leaf and flower development. On the basis of this experiment and our other data we concluded that SWP73B modulates major developmental pathways.

Arabidopsis thaliana SWP73A and SWP73B are homologs of mammalian BRAHMA-associated factors (BAF60s) that tether SWITCH/SUCROSE NONFERMENTING chromatin remodeling complexes to transcription factors of genes regulating various cell differentiation pathways. Here, we show that Arabidopsis thaliana SWP73s modulate several important developmental pathways. While undergoing normal vegetative development, swp73a mutants display reduced expression of FLOWERING LOCUS C and early flowering in short days. ...[more]

Transcript profiling of Arabidopsis er/erl1/erl2 mutant line

Project description:The members of ERECTA family (ERf) leucine-rich receptor like kinases (ERECTA, ERECTA-LIKE1, ERECTA-LIKE2) play important role in various regulatory processes like epidermal patterning, stomata development, meristem size, inflorescence architecture control and hormonal signaling. In this experiment we showed that inactivation of all three ER's causes wide range of transcriptional changes affecting developmental, hormonal and metabolic processes. Based on our transcriptomic data and other experiments we concluded that ERf's kinases are involved in transcriptional control of genes expression.

Methyl DIP-chip from self-pollinated ddm1 mutant and ddm1 kyp double mutant

Project description:Methylation of histone H3 lysine 9 (H3K9me) and small RNA are associated with constitutively silent chromatin in diverse eukaryotes including plants. In plants, silent transposons are also marked by cytosine methylation, especially at non-CpG sites. The transposon-specific non-CpG methylation in plants is controlled by small RNA and H3K9me. Although it is often assumed that small RNA directs H3K9me,　interaction between small RNA and H3K9me has not been directly shown in plants. We have previously shown that a mutation in a chromatin remodeling gene DDM1 (decrease in DNA methylation) induces a global decrease as well as local increase of cytosine methylation and accumulation of small RNA in a locus called BONSAI. Here we show that the de novo BONSAI methylation does not depend on RNAi but depends on H3K9me. Notably, in mutant of H3K9 methylase gene KRYPTONITE or H3K9me-dependent DNA methylase gene CHROMOMETHYALSE3, the ddm1-induced de novo cytosine methylation was abolished for all three contexts, CpG, CpHpG, and CpHpH. Furthermore, RNAi mutants showed strong developmental defects when combined with ddm1 mutation. Our results revealed unexpected interactions of epigenetic modifications, which could be conserved among diverse eukaryotes. comparison of DNA methylation between WT, 2G ddm1 (2 replications), 8G ddm1 (2 replications), and 8G ddm1 kyp

Espression data of control and heat-stressed Arabidopsis WT, hd2c-3, brm-1 and brm-1 hd2c-3 plants

Project description:Studies in yeast and animals have revealed that histone deacetylases (HDACs) often act as components of multiprotein complexes, including chromatin remodeling complexes (CRCs). In our group, we found evidence for the interaction between Arabidopsis HD2C deacetylase and a BRM-containing SWI/SNF chromatin remodeling complex. Moreover, we revealed a novel function of HD2C as a regulator of the heat stress response. HD2C transcript levels were strongly induced in plants subjected to heat treatment and the expression of selected heat-responsive genes was up-regulated in heat-stressed hd2c mutant, suggesting that HD2C acts to down-regulate heat-activated genes. Microarray transcriptome analysis of brm and hd2c mutants identified a subset of commonly regulated heat-responsive genes, and the effect of the double brm hd2c mutation on the expression of these genes was non-additive. Moreover, heat treated hd2c, brm and brm hd2c mutants displayed similar rates of growth retardation. Taken together, our findings suggest that HD2C and BRM act in a common genetic pathway to regulate the Arabidopsis heat stress response. 3-week-old WT (Col-0), hd2c-3, brm-1 and brm-1 hd3c-3 plants were collected before and after 1 hour of heat (38Â°C) treatment. For each variant, three biological replicates with similar expression levels of selected marker genes, were chosen for microarray analysis.

Microarray analysis of Arabidopsis Col-0 and catalase 2 mutant define interactions between CO2, daylength and H2O2

Project description:Growth daylength, ambient CO2 level, and intracellular hydrogen peroxide (H2O2) availability all impact plant function by modulating signalling pathways, but interactions between them remain unclear. Using a whole-genome transcriptomics approach, we exploited the conditional photorespiratory nature of the catalase-deficient cat2 mutant to identify gene expression patterns responding to these three factors. Arabidopsis Col-0 and cat2 grown for 5 weeks in high CO2 in short days (SD) were transferred to air in SD or long days (LD), and microarray analysis was performed. Of more than 500 genes differentially expressed in Col-0 between high CO2 and transfer to air in SD, the response of about one-third was attenuated by transfer to air in LD. H2O2-responsive genes in cat2 were highly dependent on daylength. The majority of H2O2-induced genes were more strongly up-regulated after transfer to air in SD than to LD, while a smaller number showed an opposing pattern. Responses of other H2O2-dependent genes indicate redox-modulation of the daylength control of fundamental cell processes. The overall analysis provides evidence that (1) CO2 level modulates stress-associated gene expression; (2) both CO2 and H2O2 interact with daylength and photoreceptor signalling pathways; and (3) cellular signalling pathways may be primed to respond to increased H2O2 in a daylength-determined manner. Two genotypes x five conditions experiment, including Arabidopsis Col0WT and cat2-1 plants grown in soil for 5 weeks in a 8h light/16h dark (short day) regime at high CO2 concentration (3000 ppm CO2) and subsequently transferred to air (400 ppm CO2) in a short day or long day (16h light/8h dark) regime for 2 and 4 days. Three biological replicates were used that consist each of a pool of two leaves from different plants. Each sample was hybridized to one Genechip® Arabidopsis ATH1 Genome Array (Affymetrix).

RNA-Seq of developing shoot apical meristems of barley cultivar Golden Promise (null segregant and Ubi::HvFT3 overexpressor) grown under long- and short-day photoperiods

Project description:FLOWERING LOCUS T-like genes have duplicated and functionally diverged between dicot and monocots species. The purpose of this study was to characterize the function of HvFT3 in barley (Hordeum vulgare). For this purpose, we generated transgenic lines overexpressing HvFT3 and characterized its effects on global gene expression changes in the main shoot apices at two developmental stages (spikelet initiation, lemma primordium). Analysing the function of different HvFT homologs in barley gives important insights into the genetic control of spike development and hence of yield in barley.

Arabidopsis Col-0 and cerk1 treated with chitosan or water

Project description:Microbe-associated molecular pattern (MAMP)-triggered immunity (MTI) is the first layer of molecular defense encountered by pathogens when they attempt to infect plants. MTI is dependent on cell surface pattern-recognition receptors (PRR) which act upstream of mitogen-activated protein kinase (MAPK) pathways. Genetic screening and mutant knock-out lines have largely contributed to our knowledge of MTI. However, genetic screening is confined to phenotype-causing mutations and scarcely enables the discovery of redundantly-acting proteins. We sought to discover protein components that contribute in MTI, using a phenotype-independent approach to discern nucleus-localized proteins after MTI induction. We report on the nuclear proteome of Columbia-0 (Col-0) and chitin elicitor receptor kinase 1 (cerk1) mutant plants 15 min after MTI induction. Our approach revealed that MAMP-treated cerk1 plants had many proteins in common with Col-0-treated plants following chitosan treatment. cerk1 plants also manifested several unique proteins that were absent from Col-0 plants when elicited with chitosan indicating that they also perceive chitosan. Detailed analysis of the identified proteins revealed a nuclear accumulation of transcriptional regulators and transcription factors, DNA-modifying enzymes, RNA-binding proteins and ribosomal proteins. No novel MAPKs were found although Receptor for activated C kinase 1, a scaffold protein involved in defense, and a nucleotide binding leucine-rich repeat protein, implicated in resistance to Leptosphaeria maculans, were discovered in the nucleus of chitosan-treated plants and absent from water-treated control plants.

Transcriptional profiling of the Arabidopsis abscission mutant hae hsl2 by RNA-Seq

Project description:The receptor-like protein kinases encoded by HAESA (HAE) and HAESA-LIKE 2 (HSL2) are essential for floral organ abscission in Arabidopsis thaliana and the double hae hsl2 mutant fails to abscise. Expression of HAE and HSL2 is specific to Abscission Zone (AZ) cells and is higher in stage 15 flowers than in earlier developmental stages. By stage 16 floral organs have begun to abscise, suggesting that HAE HSL2 are most active in stage 15 flowers. Samples were enriched for AZ RNA by isolating RNA from flower receptacles, the region from the base of the flower to slightly above the base of attachment of the sepals, petals, and stamen. RNA-seq was then used to analyze and compare the transcriptomes of wild type and hae-3 hsl2-3 mutants. 2034 genes were differentially expressed with a False Discovery Rate adjusted p < 0.05, of which 349 genes 2 fold or greater change. Of these 349, 277 were lower in the mutant and 72 were higher. Differentially expressed genes with lower expression were enriched for hydrolytic enzymes, cell-wall modifying enzymes, and defense related genes. This suggests that HAE HSL2 signaling regulates gene expression of enzymes necessary for abscission. 6 samples were sequenced, 3 biological replicates of Col-0 wild type and 3 biological replicates of the hae-3 hsl2-3 double mutant. Samples were barcoded and all 6 samples multiplexed and sequenced on 3 lanes, each lane on a separate flow cell, of an Illumina HiSeq 2000.

A Circular RNA Controls Ribosomal RNA Maturation and Atherosclerosis in Humans

Project description:Circular RNAs (circRNAs) are broadly expressed in eukaryotic cells, but their role in human health and disease remains obscure. Here, we show that circular antisense non-coding RNA in the INK4 locus (circANRIL), which is transcribed at a locus of atherosclerotic cardiovascular disease on chromosome 9p21, confers athero-protection by controlling ribosomal RNA (rRNA) maturation and modulating pathways of atherogenesis. At the molecular level, circANRIL competes with precursor rRNA (pre-rRNA) for binding to pescadillo homolog 1 (PES1), an essential 60S-preribosomal assembly factor, thereby impairing exonuclease-mediated pre-rRNA processing and ribosome biogenesis. As a consequence, circANRIL induces nucleolar stress and p53 activation, resulting in the induction of apoptosis and inhibition of proliferation, which are key athero-protective cell functions within the arterial wall. Collectively, these findings identify circANRIL as a prototype of a circRNA regulating ribosome biogenesis and conferring athero-protection, thereby unveiling a therapeutic potential of certain circRNAs in human disease.
