Global gene expression of Ruegeria pomeroyi DSS-3 during ammonium-limited, ribose phosphate-, methylphosphonate-, or potassium phosphate-excess growth regimes or during potassium phosphate-limited, ammonium-excess regime

ABSTRACT: We used the previously designed oligonucleotide microarrays (Bürgmann et al., 2007, Environmental Microbiology, 9: 2742-2755) to detect the mRNA transcripts of R. pomeroyi DSS-3 when the cells were cultured under steady-state conditions limited with ammonium (NH4Cl, 0.26 mM) but with an excess of D-ribose-5-phosphate (C5H9Na2O8P*2H2O, 0.5 mM), methylphosphonic acid (CH5PO3, 0.5 mM), or potassium phosphate (KH2PO4, 0.5 mM), or during ammonium excess (NH4Cl, 2.8 mM) but were limited with potassium phosphate (KH2PO4, 9.2 μM).

Global gene expression of Ruegeria pomeroyi DSS-3 during ammonium-limited, ribose phosphate-, methylphosphonate-, or potassium phosphate-excess growth regimes or during potassium phosphate-limited, ammonium-excess regime

Project description:We used the previously designed oligonucleotide microarrays (BM-CM-<rgmann et al., 2007, Environmental Microbiology, 9: 2742-2755) to detect the mRNA transcripts of R. pomeroyi DSS-3 when the cells were cultured under steady-state conditions limited with ammonium (NH4Cl, 0.26 mM) but with an excess of D-ribose-5-phosphate (C5H9Na2O8P*2H2O, 0.5 mM), methylphosphonic acid (CH5PO3, 0.5 mM), or potassium phosphate (KH2PO4, 0.5 mM), or during ammonium excess (NH4Cl, 2.8 mM) but were limited with potassium phosphate (KH2PO4, 9.2 M-NM-<M). A total of 13 microarray hybridizations were performed: three biological replicates each from ribose phosphate, methylphosphonate, or potassium phosphate excess growth regimes, three biological replicates from potassium phosphate limited growth regime, and one technical replicate for the potassium phosphate excess growth regime. Data for the technical replicates were averaged and combined, resulted in a total of 12 samples.

Proteomic profile of Pinus pinaster roots under ammonium nutrition

Project description:Ammonium nutrition was studied at short times (24 hours) in roots from one month-old seedlings of maritime pine. Control seedlings were irrigated with 80 mL of water (C) and the experimental seedlings with 80 mL of 3 mM NH4Cl. Root samples were collected at 24 hours post-irrigation and immediately frozen in liquid N. This experiment was carried out three independent times.

Global gene expression of Ruegeria pomeroyi strain DSS3 in response to glucose, ammonium, phosphate, or sulfate limitation

Project description:We used the previously designed oligonucleotide-based microarray (Burgmann et al. Environmental Microbiology 2007, 9: 2742-2755) to detect the transcripts of R. pomeroyi DSS-3 genes when the cells were cultured under steady-state carbon (glucose), nitrogen (ammonium), phosphorus (phosphate), or sulfur (sulfate) limitation. A total of 14 mRNA samples were hybridized to the arrays (three biological replicates from glucose, ammonium, phosphate, or sulfate limitation and one technical replicate each for ammonium or sulfate limitation)

Phosphate solubilization and gene expression of phosphate-solubilizing bacterium Burkholderia multivorans WS-FJ9 under different levels of soluble phosphate

Project description:Phosphate-solubilizing bacteria (PSB) have the ability to dissolve insoluble phosphate and enhance soil fertility. However, the growth and mineral phosphate solubilization of PSB could be affected by exogenous soluble phosphate and the mechanism has not been fully understood. In the present study, the growth and mineral phosphate-solubilizing characteristics of PSB strain Burkholderia multivorans WS-FJ9 were investigated at six levels of exogenous soluble phosphate (0, 0.5, 1, 5, 10 and 20 mM). The WS-FJ9 strain showed better growth at high levels of soluble phosphate. The phosphate-solubilizing activity of WS-FJ9 reduced as the soluble phosphate concentration increased, as well as the production of pyruvic acid. Transcriptome profiling of WS-FJ9 at three levels of exogenous soluble phosphate (0, 5 and 20 mM) identified 446 differentially expressed genes, among which 44 genes were continuously up-regulated when soluble phosphate concentration increased and 81 genes were continuously down-regulated. Some genes related to cell growth were continuously up-regulated which would account for the better growth of WS-FJ9 at high levels of soluble phosphate. Genes involved in glucose metabolism, including glycerate kinase, 2-oxoglutarate dehydrogenase, and sugar ABC-type transporter were continuously down-regulated which indicates that metabolic channeling of glucose towards phosphorylative pathway was negatively regulated by soluble phosphate.

Transcriptome data of Alcaligenes sp. HO-1 in response to ammonium stimulation at several time points.

Project description:A heterotrophic ammonia-oxidizing bacterium Alcaligenes sp. HO-1 was isolated from the activated sludge of a bioreactor treating ammonia-rich piggery wastewater. The goal and objectives of this experiment are to analyze the transcriptome profiles of nitrogen-metabolism-related genes of Alcaligenes sp. HO-1 in response to ammonium stimulation over time and to find out potential genes involved in ammonia oxidation process. So the RNA-seq anaylsis was performed by setting up each time points (0, 3.5, 10, 22 hours) when strain HO-1 were exposed to ammonia. HO-1 was cultured with 83 mM succinate and 14 mM ammonium sulfate until ammonia was completely consumed and then another 14 mM of ammonium sulfate was added to the culture. Cells were harvested at 0 h, 3.5 h, 10 h and 22 h after the addition of ammonium sulfate. The sequencing data of RNAs obtained from strain HO-1 cells at each time was analyzed.

Transcriptome analysis of the shoots of Arabidopsis wild-type and ammonium-insensitive mutant plants grown under 10 mM ammonium as sole nitrogen source

Project description:Abundant ammonium nutrition impairs plant growth, i.e. ammonium toxicity, the primary cause of which remains to be determined. To obtain a clue about the toxic mechanism, we performed microarray experiments and compared the expression of genes responsive to toxic levels of ammonium between the wild-type (Col) and an ammonium-insensitive mutant (ami2) shoots growing in media containing 10 mM ammonium.

Labeling Escherichia coli to saturation with 2.5 % of 15N ammonium in two conditions (aerobic and anaerobic) for benchmarking of protein-based stable isotope probing proteomics (Protein-SIP)

Project description:This dataset is part of a study aimed at developing algorithms for the quantification of stable isotope content in microorganisms after labeling them with stable isotope-labeled substrates. For this dataset Escherichia coli cultures were labeled with 2.5 % of 15N-labeled NH4Cl and grown either anaerobically or aerobically. Cultures of E. coli were grown in M9 minimal medium in which 2.5 % of the ammonium was replaced with 15N-labeled NH4Cl for >10 generations to achieve close to complete labeling of cells. Triplicate cultures were grown. Please note that the unlabeled ammonium that was used of course had a natural content of 15N of around 0.4 %, thus the 0% added label samples have an actual 15N content of 0.4 % and all added label is on top of this value. We included a tab delimited table with this submission providing details on all raw files.

Directional RNA sequencing of mRNA from Sinorhizobium meliloti cells grown with limiting phosphate and with excess phosphate.

Project description:Analysis of the RNA-seq reads confirmed that transcription of many of the previously identified Pho-regulon genes of Sinorhizobium meliloti was regulated by the availability of inorganic phosphate in the media. The transcriptional start sites of many of the Pho-regulon genes as determined by RNA-seq reads were found to correspond to those determined from primer extension analysis. mRNA from S. meliloti RmP110 grown in MOPS + 2 mM Pi and MOPS + 20 M-BM-5M Pi M-bM-^@M-^S directional RNA-seq via Illumina sequencing
