Whole genome transcript profiling upon 4 days of salt treatment

ABSTRACT: Our study identified long term salt stress treatment to induce symptoms similar to developmental senescence. In order to identify possible crosstalk components shared between developmental and salt-triggered senescence. We first obtained the expression profile of Arabidopsis leaves under the condition of salt-induced senescence (4 days) and then compared it with the transcriptome of developmental leaf senescence. Wild type Arabidopsis Col-0 plants were grown hydroponically and treated with or without 150mM NaCl and harvested after 4 days of treatment.

Salt stress and senescence: identification of cross-talk regulatory components.

Allu Annapurna Devi AD Soja Aleksandra Maria AM Wu Anhui A Szymanski Jedrzej J Balazadeh Salma S

Journal of experimental botany 20140506 14

Leaf senescence is an active process with a pivotal impact on plant productivity. It results from extensive signalling cross-talk coordinating environmental factors with intrinsic age-related mechanisms. Although many studies have shown that leaf senescence is affected by a range of external parameters, knowledge about the regulatory systems that govern the interplay between developmental programmes and environmental stress is still vague. Salinity is one of the most important environmental stre ...[more]

Expression analysis of genes affected by dehydration-responsive transcription factor Os02g31890 from rice.

Project description:Os02g31890 encodes a dehydration-responsive transcription factor (named ´ARID´) from rice (Oryza sativa, cv. Dongjin). Expression profiling was performed 90 min after the start of dehydration stress in roots of Oryza sativa wild-type plants (cv. Dongjin) and a knock-out (i.e. arid) mutant. Wild-type rice plants and a line carrying a T-DNA insertion in the third exon of the transcription factor gene (arid mutant) were subjected to dehydration stress for 90 min. Well-watered wild-type and T-DNA insertion plants were used as controls. Total RNA was extracted from roots and subjected to expression profiling using rice Affymetrix microarrays.

Transcription profiling of mouse Clcn5 knockout in proximal tubules of the kidney

Project description:Dent disease has multiple defects attributed to proximal tubule malfunction including low molecular weight proteinuria, aminoaciduria, phosphaturia and glycosuria. In order to understand the changes in kidney function of the Clc5 transporter gene knockout mouse model of Dent disease, we examined gene expression profiles from proximal tubules of mouse kidneys. Overall 720 genes are expressed differentially in the proximal tubules of the Dent Clcn5 knockout mouse model compared to those of control wild type mice. The fingerprint of these gene changes may help us to understand the phenotype of Dent disease. Experiment Overall Design: Renal proximal tubules were dissected from wild type and Clcn5 knockout mice. Mice were anesthetized with halothane, the abdominal aorta of each animal was accessed and the left kidney was perfused with an ice-cold salt. Proximal tubule dissection was performed in an ice-cold salt solution. After dissection of approximately 80-100 segments of 2 mm in length per kidney, the RNA for 3-4 mice was combined to have enough RNA per chip. Experiment Overall Design: 3 microarrays each of wild type and knockout mouse proximal tubule were processed

Transcription profiling of rat model of hypertension kidney reveals gender-selective responses to salt in Dahl-Iwai and Sprague-Dawley strains

Project description:Dahl-Iwai (DI) salt-sensitive rats were studied using microarrays to identify gender-specific differences in the kidney, both basal differences and responses to a high salt diet. In DI rat kidneys, gene expression profiles demonstrated inflammatory and fibrotic responses selectively in females. Gonadectomy of DI rats abrogated gender differences in gene expression. Gonadectomized female and gonadectomized male DI rats both responded to high salt with the same spectrum of gene expression changes as intact female DI rats. Androgens dominated the gender selective responses to salt. Several androgen-responsive genes were identified with roles potentiating the differential responses to salt including increased male expression of Angiotensin-Vasopressin Receptor and Prolactin Receptor, decreased 5-alpha reductase, and mixed increases and decreases in expression of Cyp4a- genes that can produce eicosanoid hormones. These gender differences potentiate sodium retention by males, and increase kidney function during gestation by females. Experiment Overall Design: - 68 samples/rats/data tables are represented. Experiment Overall Design: - One microarray was used for each sample. Experiment Overall Design: - 3 rat

Proteomic Analysis of Canola Inoculated with Bacteria under Salt Stress

Project description:In order to understand the salt response-mechanisms and ability of plant growth promoting bacteria to moderate harmful effect of salt, two Canola cultivars, salt-tolerant Hyola308, and salt-sensitive Sarigol, were treated with Inoculation with plant growth promoting bacteria, Pseudomonas fluorescens, and salt. For this quantitative proteomics technique was used.

Transcription profiling of human memory T cell subsets from peripheral blood.

Project description:Microarray deconvolution is a technique for quantifying the relative abundance of constituent cells in a mixture based on that mixture's microarray signature and the signatures of the purified constituents. It has been applied to yeast and other systems but not to blood samples. Here we test the ability of this technique to determine the fractions of subsets of memory T cells in peripheral blood mononuclear cell (PBMC) samples. Experiment Overall Design: PBMC samples from several donors were split. One portion of each PBMC sample was set aside, while the remainder of each was sorted into naive, central memory, and effector memory T cell subsets.

Project description:Comparative expression analysis between two highly salt-tolerant wheat lines, their parental lines, and a salt-sensitive line. The Chinese Spring (CS) line is salt sensitive. AJDAj5 and PhI are the two parental lines (with Chinese Spring background), and both have some salt-tolerance. W4909 and W4910 are two lines derived from crossing AJDAj5 and PhI, and both are more salt tolerant than either parental line.
