Exogenous sucrose (Suc) greatly enhances anoxia tolerance of Arabidopsis (Arabidopsis thaliana) seedlings. We used the Affymetrix ATH1 GeneChip containing more than 22,500 probe sets to explore the anaerobic transcriptome of Arabidopsis seedlings kept under anoxia for 6 h in presence or absence of exogenous Suc. Functional clustering was performed using the MapMan software. Besides the expected induction of genes encoding enzymes involved in Suc metabolism and alcoholic fermentation, a large num ...[more]

Transcription profiling of Arabidopsis dark grown seedlings response to 6h-long treatment with 90 mM sucrose

Project description:Dark grown Arabidopsis seedlings (Columbia gl1) were grown in the dark at 23Â°C for 4 days before adding 90 mM sucrose for 6h. Experiment Overall Design: Arabidopsis thaliana ecotype Columbia glabra (gl1-1) was used in this study. Seeds were sterilized with diluted bleach (10 min incubation in 1.7% sodium hypochlorite, rinsing and washing thoroughly in sterile water), and incubated in 2.5 ml liquid growing medium [Murashige-Skoog (MS) half strength solution] in 6-well plates (fully aerobic, with shaking). Plates were incubated in the darkness at 4Â°C for 2 days and finally transferred to 23Â°C for 4 days before the sugar treatments (with 90 mM sucrose, lasting 6h). Two independent, replicated experiments were performed for sucrose treatments. Each independent experiment consisted of four replicated seedlings cultures, pooled after RNA extraction. Experiment Overall Design: AIR EXPERIMENT 1: Control without added sucrose Experiment Overall Design: AIR EXPERIMENT 2: Control without added sucrose Experiment Overall Design: Sucrose 90 mM, 6h treatment in the dark, Biological Replicate 1 Experiment Overall Design: Sucrose 90 mM, 6h treatment in the dark, Biological Replicate 2

Transcription profiling of Arabidopdis seedlings - heat, anoxia, and combined heat-anoxia treatments

Project description:Anoxia induces several heat shock proteins and a heat pre-treatment can acclimatize Arabidopsis seedlings to a subsequent anoxic treatment. In this work we analyzed the response of Arabidopsis seedlings to anoxia, heat and a combined heat+anoxia stress. A significant overlapping between the anoxic and heat shock responses has been observed by whole-genome microarray analysis. Experiment Overall Design: We treated Arabidopsis seedling, 4-days old, dark germinated with: Experiment Overall Design: -Control (23Â°C, dark, liquid Murashige-Skoog medium containing 30mM sucrose). Experiment Overall Design: -Heat-treated (38Â°C for 90 minutes, dark, liquid Murashige-Skoog medium containing 30mM sucrose). Experiment Overall Design: -Anoxia-treated (23Â°C, under anoxia for 6h, dark, liquid Murashige-Skoog medium containing 30mM sucrose). Experiment Overall Design: -combined heat+Anoxia-treatment (23Â°C, treated at 38Â°C for 90 min and thereafter under anoxia for 6h, dark, liquid Murashige-Skoog medium containing 30mM sucrose). Experiment Overall Design: Two biological replicates for each condition.

Transcription profiling of Arabidopsis seedlings treated with chitosan

Project description:We treated Arabidopsis seedlings with chitosan and carried out a transcript profiling analysis (GeneChip microarrays) in order to identify genes and transcription factors regulated by chitosan. The results showed that jasmonate and defense responsive genes, camalexin and lignin biosynthetic genes were among genes up-regulated by chitosan. Several transcription factors are also strongly induced by chitosan. The results suggested that chitosan can be used as a strong elicitor of defense pathways. Experiment Overall Design: Arabidopsis thaliana, ecotype Columbia (Col-0) seeds were sterilized for 7 min in 1.7% (v/v) bleach solution, incubated over night in 4% PPM (Plant Preservative Mixture, Plant Cell Technology, Washington DC, USA) in a full strength sterilized Murashige-Skoog (MS) salt solution with gentle shaking. Subsequently, the seeds were rinsed in abundant sterile water and transferred into 2.5 ml liquid growing media (MS half strength solution) with 0.05% PPM in 6-well plates. The plates were incubated in the dark at 4 Â°C for two days and finally transferred to continuous light (90Âµm photons/ m-2) with gentle swirling for four days in a plant growth chamber at 22 Â°C. Experiment Overall Design: . Treatments were performed by comparing a control solution containing the solvent used to solubilize chitosan, and a chitosan solution concentrated 150 Âµg/ml.

Transcription profiling of Arabidopsis - effect of AtHRE1 and AtHRE2 overexpression in normoxia and hypoxia

Project description:HRE1 and HRE2 are two ERF transcription factors induced by low oxygen. In this work we analyzed the effect of ectopic expression of HRE1 and HRE2 on the arabidopsis transcriptome in aerobic and hypoxic (1% O2) conditions. While HRE1 has a moderate effect on the expression of anaerobic genes under hypoxia, HRE2 does not affect them either under aerobic or hypoxic conditions. Experiment Overall Design: We treated Arabidopsis seedling Col-0 (wt) and transgenic 35S::HRE1 and 35S::HRE2 , 7-day old, germinated in 12/12 light/dark photoperiod with: Experiment Overall Design: -Control (23Â°C, dark, 21% O2, 4h). Experiment Overall Design: -Hypoxia (23Â°C, dark, 1% O2, 4h). Experiment Overall Design: Two biological replicates for each condition.

Transcription profiling of early response of Arabidopsis root tips exposed to 1 hour of red light

Project description:Red light can affect a variety of responses in Arabidopsis. We characterize the early gene expression patterns of roots exposed to 1 hour of red light. Early genes indicate elements involved in photomorphogenesis, chloroplast development, PAL pathways, root hair development are regulated by 1 hour of red light; We used microarrays to detail the gene expression underlying the effects of red light on roots. Experiment Overall Design: 7 Day dark-grown 1 cm Arabidopsis root tips were harvested for RNA extraction and hybridization on Affymetrix microarrays. We pooled samples from several Petri plates for each experiment to obtain enough RNA for arrays. Three experiments were performed. Treatment 1 hour of red light 630 nm (max) and dark controls

Full-length autonomous transposable elements are preferentially targeted by expression-dependent forms of RNA-directed DNA methylation

Project description:The diversity of small RNA-directed DNA methylation (RdDM) mechanisms have been underestimated due to the nearly complete transcriptional silencing of transposable elements (TEs) in the wild-type reference strains of Arabidopsis thaliana. In plants mutant for the SWI/SNF histone remodeler DDM1, TEs are globally activated due to loss of genome wide heterochromatin condensation. Transcriptionally activated TEs go through additional non-canonical forms of RdDM that are dependent on RNA Polymerase II expression. However, the global targets of the non-canonical RdDM pathway have not been explored. In an attempt to identify and contrast the targets of canonical and expression-dependent non-canonical RdDM, we performed MethylC-seq of genome-wide DNA methylation patterns from several RdDM mutants in either the TE-silent or the TE-active (ddm1) contexts. Arabidopsis wildtype and twenty RdDM pathway mutants

rpl24b/WT polysome loading and transcript levels (Arabidopsis thaliana)

Project description:To understand the contribution of the RPL24B protein, a component of the large 60S ribosomal subunit, to the translation of specific mRNAs, we compared the ribosome occupancy of mRNAs in wild type Arabidopsis and the rpl24b/stv1-1 T-DNA insertion mutant. RNA was fractionated using sucrose gradients into polysomal and nonpolysomal RNAs. We also determined overall total transcript levels. We used Affymetrix ATH1 microarrays. Each plant sample was analyzed for the mRNA abundance in total mRNA, polysomal mRNA, and nonpolysomal mRNA. Three biological replicates were collected. The rpl24b mutant was compared with wild type.

Identification of PM-localized proteins

Project description:In order to assess the quality of alleged PM identifications from Arabidopsis, PM-enriched fractions were compared to PM-depleted fractions using 18O isotopic labeling and mass spectrometry. The two samples submitted are biological replicates. Keywords: Protein Localization via MS Two biological replicates were analyzed in order to assess sample complexity. PM-derived vesicles were digested in 18O water and compared to PM-depleted fractions digested in 16O (natural abundance) water. Relative ion intensities were then used to calculate a heavy/lite ratio with proteins showing enrichment in the upper phase having a ratio greater than 1 or 0 on a log2 scale.
