Transcription profiling of Arabidopsis plants grown under diurnal conditions and transferred to cold conditions at different times of day to identify factors influencing cold-responsive genes

ABSTRACT: Arabidopsis plants growing under diurnal conditions were transferred to cold of approximately one day duration, starting at different times of the day. All comparisons are of unreplicated pairs and are thus not designed to identify cold-responsive gens in isolation but are rather to supplement existing publicly available data. The overall aim was to use a diverse set of experiments to see which factors have the greatest influence on the identity of cold-responsive genes.

In plants, low temperature causes massive transcriptional changes, many of which are presumed to be involved in the process of cold acclimation. Given the diversity of developmental and environmental factors between experiments, it is surprising that their influence on the identification of cold-responsive genes is largely unknown. A systematic investigation of genes responding to 1 d of cold treatment revealed that diurnal- and circadian-regulated genes are responsible for the majority of the s ...[more]

Transcription profiling of Arabdiposis plants before and after cold treatment using spike-in controls to allow measurement of absolute mRNA expression at the global level

Project description:To address the neglected possibility for global mRNA changes in microarray experiments we developed a simple method to generate external controls for Affymetrix microarrays to allow these platforms to measure absolute mRNA expression at the global level. We used publicly available data to select probesets that never detect endogenous transcripts, and used PCR and IVT to generate synthetic mRNAs corresponding to them. After quality control and testing, these control transcripts were spiked into total RNA samples from plants before and after 24 h of cold treatment. Due to changes in the proportion of mRNA, these data reveal intensity-dependent bias in expression estimates based on standard all-gene normalizations. When not accounted for, this leads to false classification of the differential expression for thousands of genes.

Drosophila Gene Expression During Metamorphosis in Wild Type and Germline Minus Pupae

Project description:Drosophila melanogaster undergoes a complete metamorphosis, during which time the larval male and female forms transition into sexually dimorphic, reproductive adult forms. To understand this complex morphogenetic process at a molecular-genetic level, we performed whole genome microarray analyses. Genes were identified that were expressed during metamorphosis in both somatic and germline tissues of males and females. Additionally, genes were identified that display sex-specific differences in abundance in both of these tissues at discrete times during metamorphosis. Keywords: time course; wild type; genetic modification; Gene expression was examined at five time points during metamorphosis: 0, 24, 48, 71, and 96 hr After Puparium Formation (APF). Gene expression was examined separately in males and females for both wild type pupae and tudor (tud) progeny. tud progeny have genetically ablated germline tissues. All samples were labeled with Cy5 and compared against a common reference sample labeled with Cy3. The reference sample contained male and female wild type pupae from all stages of metamorphosis. All experiments were conducted in triplicate.

Drosophila Sex Hierarchy Regulated Gene Expression in 48 hour APF Pupae

Project description:Drosophila melanogaster undergoes a complete metamorphosis, during which time the larval male and female forms transition into sexually dimorphic, reproductive adult forms. To understand this complex morphogenetic process at a molecular-genetic level, we performed whole genome microarray analyses. In somatic tissues at 48 hour After Puparium Formation (APF), 173 sex-biased transcripts that likely function downstream of the doublesex (dsx) branch of the sex determination hierarchy were identified. The mode of regulation of the sex-specific isoforms of DSX (DSX-F and DSX-M) was examined. It was determined that for most downstream targets, DSX-F and DSX-M regulate gene expression in the same manner, but that one isoform acts as a more potent regulator. Keywords: wild type; genetic modification All microarrays were dual channel with direct comparisons of male versus female or wild type versus mutant. All samples consist of whole body pupae collected at 48 hour After Puparium Formation (APF). For each experiment, four biological replicates were analyzed in a dye-swap design.

Diurnal gills transcriptome of the oyster Crassostrea gigas fed with non-harmful and harmful algae

Project description:To assess the diurnal gene expression in gills of oyster Crassotrea gigas, gills of 6 oysters were pooled and analyzed by RNa-seq every 4h for 52h (i.e. 13 sampling times). This procedure was executed simultaneously for control oysters fed with the non-harmful algae Heterocapsa triquetra (H.t condition), and for oysters fed with the harmful algae Alexandrium minutum (A.m condition) (L:D 9:15). Alexandrium minutum exposure led to a remodeling of the cycling transcriptome in gills of Crassostrea gigas.

FRUM and EcR-regulated expression during Drosophila development

Project description:In Drosophila, male-specific FRU (FRUM) is required to establish the potential for courtship behaviors, but the downstream effectors of FRUM during development are largely unknown. A microarray-based approach identified genes that are differentially expressed as a consequence of FRUM in pupae, in both whole body and CNS tissues. Genes were also identified that are sex-differentially expressed in CNS tissues. The FRUM-regulated sets were significantly overrepresented with genes also regulated by the ecdysone regulatory pathway. Two EcR isoforms (EcRA and EcRB1) are expressed in FRUM-expressing neurons during distinct periods of metamorphosis. Males with abrogated EcRA function in FRUM-expressing neurons aggressively court other males. Transcriptional profiles of mutants with abrogated EcRA function in the fru circuit demonstrate that EcR and FRUM regulate common gene sets, including the early gene broad. These results demonstrate a novel role for EcR in specifying male courtship behavior through its actions specifically in the FRUM neural circuitry. All microarrays were dual channel with direct comparisons of male versus female, wild type versus mutant, or experimental versus control. For each experiment, four to eight independent biological samples were analyzed using a dye-swap design. Samples consisted of whole body pupae or dissected CNS collected either at 0 hour After Pupal Formation (APF), 48 hour APF, or 0-24 hour adults.

H3K36ac is an evolutionary conserved histone modification that marks active genes in plants

Project description:In eukaryotic cells, DNA is tightly packed in the nucleus in chromatin which has histones as its main protein component. Histones are subject to a large number of distinct post-translational modifications, whose sequential or combinatorial action affects genome function. Here, we report the identification of acetylation at lysine 36 in histone H3 (H3K36ac) as a modification in Arabidopsis thaliana. H3K36ac was found to be an evolutionary conserved modification in seed plants. It is highly enriched in euchromatin and very low in heterochromatin. Genome-wide ChIP-seq experiments revealed that H3K36ac is generally found at the 5â?? end of genes. Independently of gene length, H3K36ac covers about 500 bp, about two to three nucleosomes, immediately downstream of the transcriptional start. H3K36ac overlaps with H3K4me3 and the H2A.Z histone variant. The histone acetyl transferase GCN5 and the histone deacetylase HDA19 are required for normal steady state levels of H3K36ac in plants. There is negative crosstalk between H3K36ac and H3K36me3, mediated by the histone methyl transferase SDG8 and GCN5. H3K36ac levels are associated with transcriptional activity but show no linear relation. Instead, H3K36ac is a binary indicator of transcription Characterization of the genome-wide distribution of H3K36ac using ChIP-seq. Analysis of the mechanistic crosstalk in the deposition of acetylation and methylation at H3K36 by ChIP-seq of H3K36ac and H3K36me3 in sdg8-2 and gcn5-1, respectively.

Transcription profiling of mouse liver cells with a conditionally active liver clock to descriminate between rhythmic gene expression driven by cyclic systemic cues and local oscillators

Project description:The mammalian circadian timing system consists of a master pacemaker in the suprachiasmatic nucleus (SCN) that synchronizes self-sustained oscillators in most peripheral cells. Rhythmic gene expression in peripheral tissues can be driven by cyclic systemic cues emanating from the SCN or by local oscillators. To discriminate between these two mechanisms, we engineered a mouse strain with a conditionally active liver clock. Transcriptome profiling revealed that the circadian transcription of most genes depends on functional hepatocyte clocks. However, the expression of 31 genes, including mPer2, oscillates robustly in clock-arrested hepatocytes. Such genes may be implicated in the synchronization of liver oscillators

Gene expression of Drosophila melanogaster in response to multiple cold exposures

Project description:In the field, insects suffer multiple cold exposures during winter. When exposed to repeated low temperatures, Drosophila melanogaster females showed an increase in survival, but a reduction in reproduction. In this study, the microarrays were used to analyze the gene expression of female D. melanogaster after multiple, single sustained (or single prolonged) and single short cold treatments, which exposed the flies at 0 M-0C for repeated 2 h, single 10 h and single 2 h respectively. Candidate genes that were involved in 6 h recovery from different types of cold exposures were identified. After repeated cold exposures, candidates particularly included genes involved in muscle protein and muscle activity. Stress-related genes, Turandot A, Turandot C, and Turandot M were up-regulated in response to multiple cold exposures, and improve the cold survival in female D. melanogaster. This work also suggested a strong relationship between cold exposure and the immune system. I suggest that in fruit flies, chilling injuries after cold exposure may induce immune responses and contribute to recovery from cold.
