Project description:Analysis of gene expression in Arabidopsis thaliana leaf, stem and flower tissues. Columbia (Col-0) Arabidopsis thaliana plants were grown at a density of 4 plants per 5 inch square pot either in a growth chamber or a green house set to 25*C by day, 20*C by night. Days were set to a 16hr photoperiod with 125 micro mol m-2s-1 fluorescent irradiation. Expanding leaves were harvested 15 days post germination in the middle of the photoperiod (3 replicates). Expanding upper 2" of the stem with siliques and pedicels removed were harvested 29 days post germination in the middle of the photoperiod (4 replicates). Developed flowers and unopened buds were harvested 29 days post germination in the middle of the photoperiod (4 replicates). RNA and Microarray Methods: Total RNA was extracted from the plants using the Trizol method (Invitrogen, Ramonell et al. (2002) Mol. Plant Pathol. 3: 301) and purified with a silica membrane column (Qiagen, RNeasy). Twenty micrograms biotinylated complementary RNA (cRNA) was prepared as described (Hernan et al. (2003) Cancer Res. 63, 140) from the purified total RNA. The resulting cRNA was used to hybridize ATH1 Arabidopsis GeneChips (Affymetrix) using the manufacturer's protocols. The array images were analyzed with the Affymetrix Microarray Suite 5.0 software with the target intensity set to 500. Normalized signal intensities were generated by multiplying signal intensities by ratio figure which set GapC (ID_REF = 258588_s_at) to 8500. Keywords: other

Project description:Gene expression is controlled by the complex interaction of transcription factors binding to promoters and other regulatory DNA elements. One common characteristic of the genomic regions associated with regulatory proteins is a pronounced sensitivity to DNase I digestion. We reported genome-wide high resolution maps of DNase I hypersensitive (DH) sites from both seedling and flower tissues of Arabidopsis from the Columbia (Col) ecotype and the corresponding ddm1 (deficient in DNA methylation 1) mutant. We identified 38,290, 41,193, 38,313, and 38,153 DH sites in leaf (Col), flower (Col), ddm1 leaf, and ddm1 flower tissues, respectively. Approximately 45% of the DH sites in all tissue types were located within 1 kb of a transcription start site (TSS), which represents a putative promoter region. Pairwise comparisons of the DH sites derived from different tissue types revealed DH sites specific to each tissue. DH sites are significantly associated with long non-coding RNAs (lncRNAs) and conserved non-coding sequences (CNSs). The binding sites of MADS-domain transcription factors AP1 and SEP3 are highly correlated with DH sites. To map the DH sites in A. thaliana, we constructed a total of five DNase-seq libraries using leaf and flower tissues from the Columbia (Col) ecotype and a ddm1 (deficient in DNA methylation 1) mutant of Columbia. These libraries were sequenced using the Illumina Genome Analyzer. We obtained a total of 190 million (M) sequence reads from these libraries. Approximately 114 M reads had a single sequence match in the A. thaliana genome

Project description:Arabidopsis thaliana (accession- Columbia) is an important model plant. RNA-Seq based study of 36 libraries was carried out to explore transcriptional programs operating in different plant parts (seedling, rosette, root, inflorescence, flower, fruit silique, and seed) and developmental stages (2-leaf stage, 6-leaf stage, 12-leaf stage, senescence stage, dry mature and imbibed seed stage). For each tissue type and developmental stage, three individual plants were used as biological replicates.

Project description:The douple mutant Arabidopsis thaliana soc1 ful, in contrast with WT, produces an interfascicular cambium and a large wood cylinder is the flowering stem. We present the RNAseq data for polyA mRNA of different developmental stages of cambium and wood formation in Arabidopsis thaliana. We sequenced 7 stages; 4 in the woody mutant soc1-6 ful-7 (herbaceous, cambium initiation, wood initiation and leaf) and 3 stages in the WT Col-0 (herbaceous, cambium and leaf). The corresponding stem anatomy is also presented in the manuscript indicating the stage of cambium development and the production of secondary xylem.

Project description:tri38-lar - hr - Analyse the transcriptome of Arabidopsis thaliana plants developing localized acquired resistance (LAR) and a hypersensitive response (HR). The goal is to identify genes inducing LAR and/or HR. Here, we want to analyse the transcriptome of Arabidopsis thaliana developing HR. To achieve this, we used Col0 leaf tissues developing an HR reaction after inoculation of the avirulent strain of PstDC3000 carrying the gene avrRpm1. Keywords: normal vs disease comparison
