Expression data from Arabidopsis root tips rRBr mutant

ABSTRACT: The RETINOBLASTOMA–RELATED (RBR) is a key regulator of cell proliferation and differentiation in plants, and plays an important role in maintenance of the stem cell niche in the root. We used microarray analysis to characterize the transcriptional response of Arabidopsis thaliana root tips from rRBr mutant (7 samples) against Col-0 wild type (6 samples) after 4, 6 and 10 das.

Expression data from Arabidopsis root tips rRBr mutant

Project description:The RETINOBLASTOMAâRELATED (RBR) is a key regulator of cell proliferation and differentiation in plants, and plays an important role in maintenance of the stem cell niche in the root. We used microarray analysis to characterize the transcriptional response of Arabidopsis thaliana root tips from rRBr mutant (7 samples) against Col-0 wild type (6 samples) after 4, 6 and 10 das. Using the Affymetrix ATH1 GeneChips, we followed the transcriptional dynamics underlying the phenotypic changes due to RBR silencing we have analysed the rRbr line at early time points of development (4, 6 and 10 das) and compared to Col-0 wild-type. Biological replicates were performed for each sample and hybridized to the chips.

Gibberellin (GA) Treatment of Arabidopsis Root Tips

Project description:The plant hormone gibberellin (GA) represents an important regulator of growth and development. Early transcriptional events controlled by GA are not well characterised. Previous microarray studies have identified genes responsive to GA treatment in the whole seedling. The whole seedling represents many tissues where subtle effects of GA treatment in specific tissues may be masked. When treated with GA, an effect on the growth rate of roots was observed. More specifically, the shorter root of a GA-deficient plant can be rescued to wild-type length by the application of GA. This experiment was designed to identify GA-regulated genes in the root tips of Arabidopsis. The use of a GA-deficient mutant provides a greater potential to identify genes responding to GA treatment. Root tips are ideally suited for the quick uptake of the hormone treatment. There will be two biological replicates which will each consist of a control treatment at 0 minutes and 2 hours, as well as the experimental GA-treated 2 hour time point. This system provides an opportunity to compare gene expression between treated and non-treated root tips and allow the identification of early GA-responsive genes.

Gene expression of rice root tips before, at and buckled by a hard layer in two rice varieties

Project description:The aim of this study was to determine the changes in gene expression of rice root tips when they came in to contact with a hard layer (60% wax layer). Three categories of root tips were sampled; tips before the hard layer, tips that had come into contact with the hard layer and root tips which had buckled after coming into contact with the hard layer. Two genotypes (Azucena and Bala) that vary in there ability to penetrate a hard layer were selected for a genotype comparison of gene expression at the hard layer. Keywords: Genotype comparison, root impedance response

Genome-Wide HDA18-Binding Sites in Arabidopsis Root Tips

Project description:We found that histone acetylation relays positional information and that a mutant altered in the histone deacetylase (HDAC) gene family member HDA18 exhibits altered H and N epidermal cell patterning. We then performed genome-wide location (ChIP-chip) analyses by using antibody against HDA18 in transgenic HDA18 overexpression Arabidopsis plants. These analyses identified statistically significant enriched DNA associated with HDA18. A total of 286 DNA fragments were enriched as putative HDA18 protein-binding sites. Root tips of P35S:HDA18 Arabidopsis plants (Col-0) ChIPed with HDA18 antibody vs. pre-immune mouse serum.

Transcriptomic analysis of Col,arf2-7,stop1 responding to NAA.

Project description:Our objective is to study root stem cell niche. We isolated total RNA from the roots tips of 5-day-old Col-0,arf2-7 and stop1 seedlings. New genes after responding to NAA treatment, during the root development, are discovered.

Whole genome RNA-sequencing from root tips ofArabidopsis thalianalow-phosphate insensitive mutants under High and Low phosphate

Project description:Phosphate limitation constrains plant development in natural and agricultural systems. Under phosphate-limiting conditions plants activate genetic, biochemical and morphological modifications to cope with phosphate starvation. One of the morphological modifications that plants induce under phosphate limitation is the arrest of primary root growth and it is induced by the root tip contact with low phosphate media. The sensitive to proton rhizotoxicity (stop1) and aluminium activate malate transporter 1 (almt1) mutants of Arabidopsis thaliana continue primary root growth under in vitro Pi-limiting conditions, thus, to get insight into the molecular components that control primary root growth inhibition under low phosphate conditions we extracted and sequenced mRNA from the root tips (2-3 mm from the root apex) of wild-type plants (Col-0 accession) and low-phosphate-insensitive mutants almt1 and stop1 grown under low and high phosphate conditions 5 days after germination using an RNA-seq methodology.

Gene expression changes in Hebeloma cylindrosporum- Pinus pinaster ectomycorrhizal root tips compared to Hebeloma cylindrosporum free-living mycelium

Project description:Illumina HiSeq technology was used to generate mRNA profiles from Hebeloma cylindrosporum ectomycorrhizal root tips compared to free-living mycelium . Ectomycorrhizal root tips and control mycelium were harvested after 3 weeks and used for RNA extraction. Reads of 150 bp were generated and aligned to Hebeloma cylindrosporum transcripts (http://genome.jgi-psf.org/Hebcy2) using CLC Genomics Workbench 7. mRNA profiles from Hebeloma cylindrosporum ectomycorrhizal root tips and free-living mycelium were generated by Illumina HiSeq2000 sequencing (150bp). Three biological replicates were sequenced for mycorrhizal and mycelium samples.
