Expression data from wild-type and AtERF73/HRE1 knock-down line under hypoxia in Arabidopsis seedlings

ABSTRACT: To mimic natural flooding conditions, we have adopted an “open system” treatment, in which only roots are subjected to hypoxia treatment. Using microarray analysis, we identified a number of AP2/ERF genes in Arabidopsis that are induced at different stages of hypoxia treatment. we performed microarray analysis to compare gene expression profiles of wild-type and AtERF73/HRE1-RNAi20 upon normaxic or hypoxic condition, in which AtERF73/HRE1 expression was severely knocked down. Arabidopsis Affymetrix GeneChip arrays were probed with RNAs isolated from roots of untreated plants (controls) and plants treated with hypoxia for 6 h.

Plant physiology 20110310 1

A number of APETALA2 (AP2)/ETHYLENE RESPONSE FACTOR (ERF) genes have been shown to function in abiotic and biotic stress responses, and these genes are often induced by multiple stresses. We report here the characterization of an AP2/ERF gene in Arabidopsis (Arabidopsis thaliana) that is specifically induced during hypoxia. We show that under normoxic conditions, the expression of AtERF73/HRE1 can be induced by exogenous addition of 1-aminocyclopropane-1-carboxylic acid and that a combination of ...[more]

Insights into Transcriptional Regulatory Pathways on Systemic Communication under Flooding in Arabidopsis

Project description:We analyzed global transcriptional changes in both shoots and roots of root-flooded Arabidopsis seedlings by microarrays. We also interpreted the significance of the systemic communication between roots and shoots by functional classification of affected genes. We performed genetic analysis with an ethylene signaling mutant, ein2-5, to correlate systemic flooding responses with ethylene signaling. We identified a class of genes that were up- or downregulated in shoots, but not affected in roots, under hypoxic conditions. A comprehensive managing program of carbohydrate metabolism was observed, providing an example of how systemic communications might facilitate the survival of plants under flooding. A proportion of long-distance hypoxic regulation was altered in ein2-5. Time course experiments (0.5, 1, 3, 6, and 12h for Columbia; 0.5, 3, and 6h for ein2-5). Tissues from root-flooded seedlings vs. Tissues from un-flooded seedlings. Biological replicates: 4 replicates for each time point, independently grown, treated, and harvested. One replicate per array. 2 of 4 replicates are dye-swapped.

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

Expression data roots of Arabidopsis plants inoculated with Verticillium longisporum

Project description:Identification of genes differentially expressed in roots of Arabidopsis Col-0 and ndr1-1 mutants 48 h post inoculation with the fungal pathogen Verticillium longisporum. Arabidopsis Col-0 and ndr1-1 seeds were grown in petri dishes with liquid MS medium supplemented with 0.2% sucrose. After two weeks on a horizontal shaker (40 rpm), plants were rinsed twice in sterile distilled water and transferred to liquid 0.5xMS medium without sucrose, supplemented with 200 conidia ml-1 of V. longisporum isolate VL1 (CBS110220). Control plants were grown in 0.5x MS only. At 48 hours post inoculation, materials were harvested in biological replicates (>50 plant roots) and immediately frozen in liquid nitrogen. RNA was extracted with Aurum Total RNA Mini Kit (Bio-Rad) and hybridized to the Arabidopsis ATH1 Genome Array at the DNAVision facility (Gosselies, Belgium). Microarray assays were performed with triplicate biological root samples. Normalization of the microarray data was performed using the Robust Multichip Average (RMA) method as implemented by the “quantile normalization” function in the Bioconductor 1.3 software.

A combinatorial Interplay Among the ACC Synthase Isoforms Regulates Ethylene Biosynthesis in Arabidopsis thaliana

Project description:ACC Synthase (ACS) is the key regulatory enzyme in the ethylene biosynthesis in plants. It catalyzes the conversion of s-adenosylmethionine (SAM) to 1-aminocyclopropane-1-carboxylic acid (ACC), the precursor of ethylene. Arabidopsis has nine ACS genes. The goal of the project is to inactivate each gene by insertional mutagenesis and amiRNA technology and eventually construct a null ACS mutant. We have been recently able to achieve this goal. Furthermore, we wanted to know how inactivation of individual ACS genes affects global gene expression. Keywords: ACS mutant comprrison; global gene expression. Triplicate samples of 10-day light grown seedling from each ACS mutant was used for microarray analysis.

Transcription profiling of light and carbon signaling interactions in Arabidopsis

Project description:A. thaliana seeds of Columbia (Col-0) ecotype were surface-sterilized, plated on designated media and vernalized for 48 hours at 8C. Plants were grown semi-hydroponically under 16-hr-light, 8-hr-dark cycles at a constant temperature of 23C on basal Murashige and Skoog medium supplemented with 2 mM KNO3, 2 mM NH4NO3 and 30 mM sucrose. Two-week-old seedlings were transferred to fresh MS media without nitrogen and sucrose and dark-adapted for 48 hours. To perform specific metabolic treatments manipulating availability of source of carbon (C) and illumination (L): -C-L, +C-L, -C+L, +C+L, two-week-old seedlings were transferred to fresh MS medium containing 0% or 1% sucrose and either placed back into the dark or illuminated with white light for an additional 8 hours. The various treatments were compared to one another using the treatment of -C-L as the background treatment to which all other treatments (-C+L, +C-L, +C+L) were compared.
