Trithorax function is essential for epigenetic maintenance of gene expression in animals, but little is known about trithorax homologs in plants. ARABIDOPSIS TRITHORAX1 (ATX1) was shown to be required for the expression of homeotic genes involved in flower organogenesis. Here, we report a novel function of ATX1, namely, the epigenetic regulation of the floral repressor FLOWERING LOCUS C (FLC). Downregulation of FLC accelerates the transition from vegetative to reproductive development in Arabido ...[more]

Transcription profiling of control and catalase-deficient Arabidopsis (Arabidopsis thaliana) plants

Project description:In plants, reactive oxygen species and, more particularly, hydrogen peroxide (H2O2) play a dual role as toxic by-products of normal cell metabolism and as regulatory molecules in stress perception and signal transduction. Peroxisomal catalases are an important sink for photorespiratory H2O2. Using ATH1 Affymetrix microarrays, expression profiles were compared between control and catalase-deficient Arabidopsis (Arabidopsis thaliana) plants. Reduced catalase levels already provoked differences in nuclear gene expression under ambient growth conditions, and these effects were amplified by high light exposure in a sun simulator for 3 and 8 h. This genome-wide expression analysis allowed us to reveal the expression characteristics of complete pathways and functional categories during H2O2 stress. In total, 349 transcripts were significantly up-regulated by high light in catalase-deficient plants and 88 were down-regulated. From this data set, H2O2 was inferred to play a key role in the transcriptional up-regulation of small heat shock proteins during high light stress. In addition, several transcription factors and candidate regulatory genes involved in H2O2 transcriptional gene networks were identified. Comparisons with other publicly available transcriptome data sets of abiotically stressed Arabidopsis revealed an important intersection with H2O2-deregulated genes, positioning elevated H2O2 levels as an important signal within abiotic stress-induced gene expression. Finally, analysis of transcriptional changes in a combination of a genetic (catalase deficiency) and an environmental (high light) perturbation identified a transcriptional cluster that was strongly and rapidly induced by high light in control plants, but impaired in catalase-deficient plants. This cluster comprises the complete known anthocyanin regulatory and biosynthetic pathway, together with genes of hitherto unknown function.

De novo transcriptome assembly and characterization of nine tissues of Lonicera japonica to identify potential candidate genes involved in chlorogenic acid, luteolosides, and secoiridoid biosynthesis pathways

Project description:In this study, we performed de novo transcriptome assembly for L. japonica, representing transcripts from nine different tissues. A total of 22Gbps clean RNA-seq reads from nine tissues of L. japonica were used, resulting in 243,185 unigenes, with 99,938 unigenes annotated based on homology search using blastx against NCBI-nr protein database. Unsupervised principal component analysis and correlation studies using transcripts expression data from all nine tissues of L. japonica showed relationships between tissues explaining their association at different developmental stages. Homologs for all genes associated with chlorogenic acid, luteolin, and secoiridoid biosynthesis pathways were identified in the L. japonica transcriptome assembly. Expression of unigenes associated with chlorogenic acid were enriched in stem and leaf-2, unigenes from luteolin were enriched in stem and flowers, while unigenes from secoiridoid metabolic pathways were enriched in leaf-1 and shoot apex. Our results showed that different tissues of L. japonica are enriched with sets of unigenes associated with a specific pharmaceutically important metabolic pathways, and therefore, possess unique medicinal properties. Present study will serve as a resource for future attempts for functional characterization of enzyme coding genes within key metabolic processes.

affy_floral_rose-Study of floral initiation and recurrent blooming in rose

Project description:affy_floralangers_rose - affy_floral_rose - - Which genes are induced during floral initiation? - Are the genes involved in floral initiation identical between our 3 genotypes? - Which genes are involved in the control of recurrent blooming in rose? - Which genes are diferentially expressed between buds that will become floral and buds that will remain vegetative?-This project aims to find in rose genes involved in flowering control (floral initiation and recurrent flowering). First, the floral initiation will be observed in 3 genotypes. Then we will check if same genes are regulated within genotypes for this process. Concerning recurrent blooming, we will compare flower bud versus vegetative buds in non-recurrent conditions and finally bud from non-recurrent and recurrent genotypes.

RNA-Seq of developing shoot apical meristems of barley cultivar Bonus and two allelic praematurum-c/mat-c mutants mat.c.907 (NGB 116862) and mat.c.943 (NGB 117474) grown under long- and short-day photoperiods

Project description:Natural variation in the barley homolog of CENTRORADIALIS (HvCEN), was found to contribute to the expansion of barley cultivation into diverse habitats. It has been shown that induced hvcen mutants, originally designated as praematurum-c/maturity-c (mat-c) mutants, flowered a few days earlier under natural long-day conditions. All hvcen mutants flowered early and showed a reduction in spikelet number per spike, tiller number and yield in the outdoor experiments. Further evaluating development of main shoot apex of hvcen mutants and wild type under controlled long day and short day conditions showed that mutations in hvcen accelerated spikelet initiation and reduced axillary bud number in a photoperiod independent manner, but promoted floret development only under long days. In this project we investigate the pleiotropic effects of HvCEN on developmental timing and shoot and spike morphologies of barley and dependence on these effects on photoperiod. This RNAseq dataset was generated to identify the putative transcriptional targets of HvCEN. To this end, we used global transcriptome profiling in developing shoot apices and inflorescences of two allelic hvcen mutants (mat-c.907 and mat-c.943) and wild-type (Bonus) plants grown under long- and short-day photoperiods.

The response and recovery of Arabidopsis thaliana transcriptome to phosphate starvation [At35b_MR]

Project description:Background: Over application of phosphate fertilizers in modern agriculture contaminates waterways and disrupts natural ecosystems. Nevertheless, this is a common practice among farmers, especially in developing countries as abundant fertilizers are believed to boost crop yields. The study of plant phosphate metabolism and its underlying genetic pathways is key to discovering methods of efficient fertilizer usage. The work presented here describes the first genome-wide resource on the molecular dynamics underpinning the response and recovery in roots and shoots of Arabidopsis thaliana to phosphate-starvation. Results: Genome-wide profiling revealed minimal overlap between root and shoot transcriptomes suggesting two independent phosphate-starvation regulons. Novel gene expression patterns were detected for over 1000 candidates and were classified as either initial, persistent, or latent responders. Comparative analysis to AtGenExpress identified novel cohorts of genes co-regulated across multiple stimuli. The hormone ABA displayed a dominant role in regulating many phosphate-responsive candidates. Analysis of co-regulation enabled the determination of primary versus redundant members of closely related gene families with respect to phosphate-starvation. Thus, among others, we show that PHO1 acts in shoot, whereas PHO1;H1 is likely the primary regulator in root. Conclusion: Our results uncover a much larger, staged responses to phosphate-starvation than previously described. To our knowledge, this work describes the highest resolution of genome-wide data on plant nutrient stress to date. 2 tissues X 3 treatments X 3 biological replicates

Cell type specific gene expression map of Arabidopsis thaliana SAM.

Project description:Shoot apical meristem (SAM) of higher plant composed of a few distinct cell types. All the cells in a mature plant’s SAM derived from 30~35 stem cells reservoir which are located at the tip of the apex. Plants ability to give rise diverse cell types from a pool of pluripotent stem cells requires orchestrated gene network that controls the cell fate commitment during the meristem development. To understand, how gene regulatory networks control cell identities switches during cell differentiation requires resolution in recording their gene expression pattern at single cell resolution. An earlier expression map involving three-cell population of stem cell niche revealed complex expression pattern among the cell types1. We developed this approach further and report here a gene expression map using cell-sorting methods for fluorescent protein marked cells in Arabidopsis shoot. The map covered 10 cell populations. This gene expression map represents data from 10 different cell types from Arabidopsis SAM. It will be first step in defining the function of many unknown genes in model plant Arabidopsis. Based on the in situ hybridization we identified 7 new cell types specific gene expression patterns. The promoters of these genes were used to generate fluorescent reporters. After treating the SAM with protoplasting cocktail, we sorted the fluorescent protein tagged cells using fluorescent activated cell sorter (FACS). The purified cell population was used to isolate RNA. Two round of RNA amplification was performed before microarray hybridization.
