TranscriptomicsExpressionprofiling of a glnR-mutant of Mycobacterium tuberculosis during culture on nitrate
Identification of glnR-dependent regulation of nitrate assimilation Keywords: genetic modification Mycobacterium tuberculosis H37Rv wild type and glnR mutant strain were incubated in minimal medium supplemented with 5 mM NO3 for 18 and 48 hours. RNA was extracted at indicated time points and microa...

TranscriptomicsNitrate Stress in Desulfovibrio vulgaris Hildenborough
Using data from microarray experiments, we investigated the effects of excess sodium nitrate on Desulfovibrio vulgaris. Keywords: stress response, time course Comparison of cells treated with 105 mM sodium nitrate to untreated cells at times of 0, 30, 60, 120, and 240 min.

TranscriptomicsTranscription profiling of Arabdiopsis wild type and G'4-3 seeds grown with different nitrate concentrations to investigate effects on seed dormancy
Freshly harvested Arabidopsis seeds (ecotype Col0 obtained under 10 mM nitrate nutrition, referred to as C10 seeds) are dormant and do not germinate when sown on an agarose-based medium. However, when C10 seeds are sown on 10mM nitrate or when Col0 mother plants are grown on 50 mM nitrate (referred...

ProteomicsNitrate reduction to ammonia by Acididesulfobacillus acetoxydans, an acidophilic sulfate reducing bacterium
Acididesulfobacillus acetoxydans is an acidophilic sulfate reducer that can dissimilatory reduce nitrate to ammonia (DNRA). However, no known nitrite reductase is encoded. This study was performed to investigate how A. acetoxydans reduces nitrate to nitrite and elucidated a novel DNRA mechanism and ...

TranscriptomicsDiatom transcriptomics under nitrate limitation
Here, we examined the ramifications of between-species diversity by documenting the transcriptional response of three marine diatoms - Thalassiosira pseudonana, Fragilariopsis cylindrus, and Pseudo-nitzschia multiseries - to the onset of nitrate limitation of growth, a common limiting nutrient in th...

TranscriptomicsUnderstanding strategy of nitrate and urea assimilation in a Chinese strain of Aureococcus anophagefferens through RNA-seq analysis
Purpose: RNA-seq technology was used to profile the transcriptome of a Chinese strain of A. anophagefferens that was grown on urea, nitrate, and a mixture of urea and nitrate, and that was under N-replete, limited and recovery conditions to understand the molecular mechanisms that underlie nitrate a...

TranscriptomicsImpact of NRT1.1 point mutants on gene expression under high NH4NO3 supply
NRT1.1 is a nitrate transceptor involved in many nitrate responses including the regulation of gene expression through (i) the Primary Nitrate Response (PNR) and (ii) the regulation the NRT2.1 gene under continuous high NH4NO3 conditions. Phosphorylation of NRT1.1’s T101 residue is involved in the m...

Transcriptomicscitrate vs nitrate Reducing cultures
The effect of nitrate reduction (anaerobic cultivation in the presence of heme, vitamin K2 and nitrate) was compared with anaerobic cultivation supplemented with citrate (Lactobacillus plantarum). The medium was chemically defined medium with mannitol as main carbon source Two-condition experiment, ...
