MetabolomicsMulti-omics analysis of xylem sap uncovers dynamic modulation of poplar defenses by ammonium and nitrate
Xylem sap is the major transport route for nutrients from roots to shoots. In the present study, we investigated how variations in nitrogen (N) nutrition affected the metabolome and proteome of xylem sap and the growth of the xylem endophyte Brennaria salicis, and we also report transcriptional re-w...

TranscriptomicsEnhanced photorespiratory and TCA pathways by elevated CO2 to manage ammonium nutrition in tomato leaves
This work aims to study wether the increment of the atmospheric carbon dioxide (CO2) concentration, in the context of climate change, will potentially allow plants to better face ammonium nutrition. Tomato (Solanum lycopersicum L.) plants were grown for 4 week with 15 mM of nitrogen, supplied as nit...

TranscriptomicsMeasuring transcriptional differences between Caulobacter crescentus cultured in nitrate versus ammonium as the sole nitrogen source
This study is measuring the steady-state levels of mRNA in wild-type Caulobacter crescentus grown in M2 defined medium containing either ammonium or nitrate as the sole nitrogen source. Four independent cultures of Caulobacter crecentus were grown in each of two medium conditions: M2(nitrate)glucose...

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

TranscriptomicsTranscription profiling of yeast under conditions of ammonium, L-alanine or L-glutamine limitation
Response of Saccharomyces cerevisiae to Ammonium, L-alanine, or L-glutamine Limitation. The protrotophic laboratory strain CEN.PK113-7D (MAT a) was grown in laboratory fermentors with a working volume of 1 litre at dilution rate (D) of 0.20 per hour (in triplicate for each nitrogen limited condition...

TranscriptomicsComparison of root transcriptomes in Arabidopsis thaliana plants supplied with different forms of inorganic nitrogen
Plants aquire nitrogen from the soil, most commonly in the form of either nitrate or ammonium. Unlike ammonium, nitrate must be reduced (with NADH and ferredoxin as electron donors) prior to assimilation. Thus, nitrate nutrition imposes a substantially greater energetic cost than ammonium nutrition....

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

ProteomicsAmmonium Sulfate-based Prefractionation Improved Carbonylated Proteome Coverage in Arabidopsis thaliana Leaf Extract
The hypothesis that ammonium sulfate-based protein precipitation can help prefractionate the total protein extract into fractions of reduced complexity and improve the detection of low-abundance proteins was investigated. This dataset resulted from the experiments that we performed to improve the de...
