MetabolomicsThe response of Chlamydomonas reinhardtii to nitrogen deprivation: a systems biology analysis

Drastic alteration in macronutrients causes large changes in gene expression in the photosynthetic unicellular alga Chlamydomonas reinhardtii. Preliminary data suggested that cells follow a biphasic response to this change hinging on the initiation of lipid accumulation, and we hypothesized that ...

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...

MetabolomicsArsenic-induced enhancement of diazotrophic recruitment and nitrogen fixation in Pteris vittata rhizosphere
Heavy metal contamination poses an escalating global challenge to soil ecosystems. Hyperaccumulators play a crucial role in environmental remediation and resource recovery. The enrichment of diazotrophs and resulting nitrogen accumulation promoted hyperaccumulator growth and facilitated phytoremedia...

MetabolomicsPhysiological, Transcriptomic, and Metabolomic Insights into Ammonia-Nitrogen Stress in the Hepatopancreas of Litopenaeus vannamei Acclimated to Low Salinity
High ammonia nitrogen stress markedly decreases the survival rate of Litopenaeus vannamei under low-salinity conditions. Nevertheless, most available studies have primarily focused on the ammonia nitrogen response of small-sized shrimp under single-stressor exposure or normal seawater salinity. The ...

MetabolomicsClock regulation of metabolites reveals coupling between transcription and metabolism
The circadian clock is intricately connected with metabolism, however the precise details of these connections are incomplete. Here we used high temporal resolution metabolite profiling to determine circadian regulation of mouse liver and cell autonomous metabolism. In mouse liver, we found ~50% of ...

TranscriptomicsTranscriptional responses of yeast to preferred and non-preferred nitrogen sources in C-lim chemostat cultures
Aerobic, glucose-limited chemostat cultures of Saccharomyces cerevisiae grown with six different nitrogen sources were subjected to transcriptome analysis. The use of chemostats enabled an analysis of nitrogen-source-dependent transcriptional regulation at a fixed specific growth rate. A selection o...

MetabolomicsMicroRNA-mediated regulation of lipid metabolism in virus-infected Emiliania huxleyi.
The interactions between Emiliania huxleyi and E. huxleyi virus (EhV) regulate marine carbon and sulfur biogeochemical cycles and play a prominent role in global climate change. As a large DNA virus, EhV has developed a novel 'virocell metabolism' model to meet its high metabolic needs. Although it ...

MetabolomicsSynergistic regulation of Codonopsis pilosula growth and metabolism by Trichoderma, salicylic acid and methyl jasmonate
Endophytic fungi can mediate salicylic acid (SA)- and methyl jasmonate (MeJA)-related signaling in medicinal plants, thereby influencing metabolite synthesis, stress resistance, and growth development. Experimental groups comprised control, Trichoderma longibrachiatum inoculation (FG), FG+SA (FS), F...

MetabolomicsCoordinate Regulation of Metabolite Glycosylation and Stress Hormone Biosynthesis by TT8 in Arabidopsis
Secondary metabolites play a key role in coordinating ecology and defense strategies of plants. Diversity of these metabolites arise by conjugation of core structures with diverse chemical moieties, such as sugars in glycosylation. Active pools of phytohormones, including those involved in plant str...
