MetabolomicsMetabolomic Analysis of Fission Yeast at the Onset of Nitrogen Starvation
Microorganisms naturally respond to changes in nutritional conditions by adjusting their morphology and physiology. The cellular response of the fission yeast S. pombe to nitrogen starvation has been extensively studied. Here, we report time course metabolomic analysis during one hour immediately af...

TranscriptomicsDistinctive responses to nitrogen starvation in the dominant active mutants of the fission yeast Rheb GTPase.
Rheb, a ras-like small GTPase conserved from human to yeast, controls Tor kinase and plays a central role in regulation of cell growth depending on extracellular conditions. Fission yeast Rheb regulates amino acid uptake as well as response to nitrogen starvation. In this study we generated two muta...

MetabolomicsSpecific biomarkers for stochastic division patterns and starvation-induced quiescence under limited glucose levels in fission yeast
Glucose as a source of energy is centrally important to our understanding of life. We investigated the cell division-quiescence behavior of the fission yeast Schizosaccharomyces pombe under a wide range of glucose concentrations (0-111 mM). The mode of S. pombe cell division under a microfluidic per...

ProteomicsChlorella sp. FC2 IITG temporal nitrogen-starvation LC-MSMS
Proteomics study in non-model alga Chlorella FC2 IITG (FC2) challenged with nitrogen starvation for 120 h. Three different nitrogen starvation time-points 40 h, 88 h and 120 h was compared with 0 h (nitrogen sufficient condition). Comparative proteomics analysis was performed using 4-plex isobaric t...

TranscriptomicsThree acyltransferases and a nitrogen responsive regulator are implicated in nitrogen starvation-induced triacylglycerol accumulation in Chlamydomonas
Three acyltransferases, DGAT1, DGTT1, and PDAT1, are induced by nitrogen starvation and are likely to have a role in TAG accumulation based on their patterns of expression. Each gene also shows increased mRNA abundance in other TAG-accumulating conditions (-S, -P, -Zn, -Fe). Insertional mutants, pda...

TranscriptomicsGene Expression in the Rice Blast Fungus, Magnaporthe grisea, During Nitrogen Starvation
This experiment was designed to analyze transcriptional changes that occur when the fungal plant pathogen M. grisea is shifted from a complete media to a nitrogen-starved media. Comparisons were made in the following way between fungal mycelial grown in minimal media supplemented with a nitrogen sou...

TranscriptomicsCandida albicans Nitrogen Response
To infer transcriptional networks of nitrogen utilization , Candida albicans was exposed to nitrogen starvation for four hours and then offered arginine or BSA as sole nitrogen source. Time-series transcription data was obtained from both the starvation and the feeding periods, and the response to d...
