Benzoxazinoids in root exudates of maize attract Pseudomonas putida to the rhizosphere.

Neal Andrew L AL Ahmad Shakoor S Gordon-Weeks Ruth R Ton Jurriaan J

PloS one 20120424 4

Benzoxazinoids, such as 2,4-dihydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one (DIMBOA), are secondary metabolites in grasses. In addition to their function in plant defence against pests and diseases above-ground, benzoxazinoids (BXs) have also been implicated in defence below-ground, where they can exert allelochemical or antimicrobial activities. We have studied the impact of BXs on the interaction between maize and Pseudomonas putida KT2440, a competitive coloniser of the maize rhizosphere with ...[more]

Transcriptional profiles of Campylobacter jejuni NCTC 11168 to 4mg/L erythromycin treatment

Project description:Erythromycin is the drug of choice to treat campylobacteriosis, but resistance to this antibiotic is rising. The adaptive mechanisms employed by Campylobacter jejuni to erythromycin treatment remain unknown. The aim of this study is to determine the molecular basis underlying CampylobacterM-bM-^@M-^Ys immediate response to Ery treatment. The design utilized an available two color microarray slide for the entire transcriptome of Campylobacter jejuni wild type strain NCTC 11168. One hybridizations were performed: sham-treated NCTC 11168 v.s. lethal dose erythromycin treated NCTC 11168. Samples were independently grown and harvested. There were three biological replicates of each sample.

Gene expression profile of a S. cerevisiae strain deleted in CSN5/RRI1 gene (systematic name YDL216C)

Project description:The COP9 signalosome (CSN) is a highly conserved eukaryotic protein complex which regulates the Cullin-RING family of ubiquitin ligases and carries out a deneddylase activity that resides in subunit 5 (CSN5). The budding yeast CSN is biochemically active and deletion mutants of each of its subunits exhibit deficiency in deneddylation of cullins, although the biological context of this activity is still unknown in this organism. To further characterize CSN function in budding yeast, we present here a transcriptomic analysis of a S. cerevisiae strain deleted in CSN5/RRI1 gene (hereafter referred to as CSN5), coding for the only canonical subunit of the complex. We show that Csn5 is involved in the modulation of the genes controlling aminoacid and lipid metabolism, and especially ergosterol biosynthesis. These alterations in gene expression correlate with the lower ergosterol levels and increased intracellular zinc content which we observed in csn5 null mutant cells. Two biological replicates, csn5 deleted strain vs. isogenic wild-type strain W303

Comparison of osmotic stress related gene expression in Col-0, sid2-1 single, wrky54wrky70 double and wrky54wrky70sid2-1 triple mutants.

Project description:To explore the possible cause for the enhanced tolerance to osmotic stress exhibited by wrky54wrky70 double mutant, we have used Agilent Arabidopsis (V4) Gene Expression Microarray to characterize the effect of these mutations under the osmotic stress treatment. In addition to wild type and wrky54wrky70 double mutant, sid2-1 single and wrky54wrky70sid2-1 triple mutant were also included in the microarray experiment. When comparing to untreated control samples, 58 genes were identified as representatives to show the different expression level among different mutants under the 15% PEG6000 treatment for one day. Expression of six genes (RAB18, LTI78, KIN1,NCED3,P5CS1 and PRODH) from this gene list were quantified by qRT-PCR, confirming the suppressed induction in wrky54wrky70 double mutant under the osmotic stress. Osmotic stress induced gene expression in Col-WT, sid2-1 single, wrky54wrky70 double and wrky54wrky70sid2-1 triple mutants was measured after exposure to 15% PEG6000 treatment for one day. For each array, three labeled aRNA sample were hybridized and three biological replicates for each sample with dye swaps were made.

The IHF regulon of exponentially growing Pseudomonas putida cells

Project description:Integration host factor (IHF) sites are largely absent from intergenic regions of ORFs encoding central metabolic functions in Pseudomonas putida mt-2. To gain an insight into this unequal distribution of otherwise abundant IHF-binding sequences, the transcriptome of IHF-plus and IHF-minus cells growing exponentially on glucose as sole carbon source was examined. In parallel, the cognate metabolic fluxes of the wild-type P. putida strain and its ihfA derivative were determined by culturing cells to a steady-state physiological regime with (13) C-labelled glucose. While expression of many transcripts was altered by the lack of IHF, flux balance analysis revealed that the ihfA mutation did not influence central carbon metabolism. Identification of multiple IHF sites adjacent to genes responsive to the factor allowed a refinement of the consensus and the mapping of the preferred binding positions for activation or repression of associated promoters. That few (if any) of the genes affected by IHF involved core pathways suggested that the central carbon metabolism tolerates the loss of the factor. Instead, IHF controlled various cell surface-related functions and downregulated genes encoding ribosomal proteins, the alpha subunit of RNA polymerase and components of the ATP synthase. These results were confirmed with lacZ fusions to a suite of promoters detected in the transcriptome as affected by IHF. Taken together, the data suggest that IHF plays a role in the physiological shift that sets P. putida for entering stationary phase. We compared the transcriptional profiles of P. putida mt-2 and the ihfA mutant. Samples were hybridized on a P. putida genome-wide oligonucleotide-based DNA microarray (Progenika Biopharma SA). RNA samples of seven independent biological samples were mixed in three pools. A dye-swap was performed.

Clostridium difficile strain 630 heat stress experiment

Project description:Transcriptomic analysis of C. difficile strain 630 subjected to a clinically relevant heat stress (41M-BM-0C ) and compared to unstressed cells (37M-BM-0C ). Heat stress was induced in biological triplicate broth cultures in the early exponential phase (D650nm=0.3) of growth and cells were harvested at late log phase (D650 = 1.1). Goal was to determine effects of mild heat stress on gene expression. Two condition experiment, heat stressed vs. control.

Tiling microarray analysis of gene expression profile of Escherichia coli galT mutant cells under D-galactose-stressed condition

Project description:To understand the altered gene expression by D-galactose in galT cells, the cells were grown in the presence and absence of D-galactose and tiling array analysis was performed for transcriptome profiling. A galT defect causes the disease Galactosemia in human. This work helps us to study the human metabolic disease Galactosemia. Total RNAs were isolated from Escherichia coli galT strain grown in the absence and presence of D-galactose. The transcriptome profile of galT cells was figured out in the galactose-stressed condition.
