Expression data for drought-, cold, high-salinity and ABA treatment in Arabidopsis plants

ABSTRACT: We applied the tiling arrays to study the Arabidopsis whole-genome transcriptome under drought, cold, high-salinity and ABA treatment conditions and idenfied many stress- or ABA- responsive putative functional RNAs and fully-overlapping sense-antisense transcripts in Arabidopsis genome. Keywords: stress response Two-week-old Arabidopsis plants grown on the agar plates were subjected to the stress- or ABA- treatments. The total RNA was prepared from the treated- and untreated- plants, and used for the microarray hybridization. Three replicative hybridization experiments for each strand array were carried out using the independent biological RNA samples.

Plants respond and adapt to drought, cold and high-salinity stresses in order to survive. In this study, we applied Arabidopsis Affymetrix tiling arrays to study the whole genome transcriptome under drought, cold, high-salinity and ABA treatment conditions. The bioinformatic analysis using the tiling array data showed that 7,719 non-AGI transcriptional units (TUs) exist in the unannotated "intergenic" regions of Arabidopsis genome. These include 1,275 and 181 TUs that are induced and downregulat ...[more]

Expression data in Arabidopsis hda6 mutant axe1-5 and its parental line DR5 under cold and control conditions.

Project description:To understand the role of Arabidopsis histone deacetylase HDA6 in plant cold acclimation, we have employed transcriptional profiling of the hda6 mutant and its parental line under cold and control conditions to identify genes differentially expressed in the hda6 mutant under cold and control conditions. Aligent’s Whole Arabidopsis Gene Expression Microarray (G2519F, V4, 4x44K) were used. Arabidopsis hda6 mutant axe1-5 and its parental line DR5 were grown in MS agar plates for 2 weeks (16 hours light / 8 hours dark). For cold treated sample, the plants were subjected for cold treatment at 2?C for 3 days (12 hours light / 12 hours dark). Then total RNA was prepared and used for the microarray hybridization. Three replicative hybridization experiments for each array were carried out using the independent biological samples.

Fine-tuning of the anaerobic response in plants relies on trihelix protein repression of the oxygen sensing machinery

Project description:This study analyzes transcriptomic data of Arabidopsis thaliana Col-0 and overexpression lines of Hypoxia Response Attenuator (HRA1; At3g10040) with Col-0 background (OE-HRA1). Two independent transgenic lines of OE-HRA1 were considered as biological replicates (OE-HRA1#1 and OE-HRA1#2). Seven-day-old seedlings were treated either with or without hypoxia (low oxygen) stress for 2 hours. This dataset includes CEL files, RMA signal values and MAS5 P/M/A calls from total mRNA populations. Quantitative profiling of cellular mRNAs was accomplished with the Affymetrix ATH1 platform. 8 samples, 2 genotypes (Col-0 and OE-HRA1), 2 conditions (2 h non-stress and 2 h hypoxia stress), 2 independent biological replicate experiments

Small RNA sequencing in tomato roots with and without Rhizophagus irregularis

Project description:Arbuscular mycorrhizal symbiosis is a predominant relationship between plant and arbuscular mycorrhizal fungi. To idendify arbuscular mycorrhiza responsive miRNAs, small RNA libraries were constructed in tomato roots colonized with Rhizophagus irregularis and without Rhizophagus irregularis. We identify miRNAs in tomato roots and provide a new profile of tomato miRNAs. And we found that some miRNAs were responsive to arbuscular mycorrhiza by comparing miRNAs in treatment with that in control. Examination of arbuscular mycorrhiza responsive miRNAs in tomato through high-throughput small RNA sequencing of roots with Rhizophagus irregularis and that without Rhizophagus irregularis

Transcription profiling of Arabidopsis response to cold on soil

Project description:Arabidopsis plants were grown in plastic pots filled with peat moss for 3 weeks (principal growth stage 1.07-1.08) under a 16 h light/8 h dark regimen (40 ± 10 ?mol photons/m2/s) at 22 C. The light intensity was the same at 22 C and at 4 C. Plants were harvested 2 h later after lights were turned on. Cold treatment: The 3-week-old plants were transferred from 22 C to 4 C and were grown for 1 or 4 days.

Expression data in Arabidopsis axe1-5 and met1-3 mutants.

Project description:We applied the tiling arrays to study the Arabidopsis whole-genome transcriptome in Arabidopsis axe1-5 and met1-3 mutants. Fifteen-day-old Arabidopsis plants grown on the agar plates were harvested. The total RNA was prepared from 15-day-old Arabidopsis plants (axe1-5 (hda6 mutant), DR5 (parental line of axe1-5), met1-3 and Col) and used for the microarray hybridization. Three replicative hybridization experiments for each strand array were carried out using the independent biological RNA samples.

Expression data from OsRP1L1-overexpressing plant leaf in japonica rice (cv. Ishikari-shiroge (I-S))

Project description:A novel rice NBS-LRR gene was cloned and overexpressed to explore its function in bacterial blight (BB) resistance. Due to its similarity to the Rp1 gene in maize (Zea mays), it was designated as OsRP1L1. We used microarrays to detail the global reprogram of gene expression in OsRP1L1-overexpressing plants. To find out pathways and genes related to this defense-related gene, microanalysis were carried out on OsPR1L1-overexpressing plants. Three independent replicates were perfomed for overexpressing plants and wild type plants.

Genome wide expression analysis of psaA and psbA tobacco mutant plants.

Project description:Transcriptome analysis in tobacco mutant plants using tomato Genechip Genome array Tobacco (Nicotiana tabacum cv. Petit Havanna) psaA and psbA deletion mutants were constructed through a targeted deletion of 767 and 1152 nucleotides of coding regions, respectively with two gene cassettes: psbAproR:uidA:psbterR and rrnR:aadA:rbcLterR coding for GUS reporter and spectinomycin selectable marker genes, respectively. Standard established procedures were followed for chloroplast transformation to generate the psaA and psbA deletion mutants based on the homologous recombination. Gene expression profiles in psaA and psbA tobacco mutant plants were analyzed using tomato Genechip Genome array to study the global changes in the expression of genome. Total RNA was isolated from psaA and psbA tobacco mutant plants along with the wild type plants. Biotin labeled cRNA was hybridized on tomato GeneChip Genome Array following the Affymetrix protocols. Two independent biological replicates were maintained.
