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...

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...

TranscriptomicsTranscriptional characterization of maize roots in response to urea and nitrate
Although urea is the most used nitrogen fertilizer worldwide, little is known on the capacity of crop plants to use urea per se as a nitrogen source for development and growth. To date, the molecular and physiological bases of its transport have been investigated only in a limited number of species....

ProteomicsCoordination of cyanobacterial nitrate assimilation and photosynthesis by a novel PsbO-interacting protein PirN
Nitrogen assimilation relies on photosynthetically-produced energy and reducing equivalents. Here, we identify a small protein, PsbO-interacting regulator of nitrate assimilation (PirN), as a key coordinator of photosynthesis and nitrate assimilation in Synechocystis sp. PCC 6803 (Synechocystis). Pi...

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...

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....

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...

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...
