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 ...

MetabolomicsRapid UHPLC-MS metabolite profiling and phenotypic assays reveal genotypic impacts of nitrogen supplementation in oats
INTRODUCTION: Oats (Avena sativa L.) are a whole grain cereal recognised for their health benefits and which are cultivated largely in temperate regions providing both a source of food for humans and animals, as well as being used in cosmetics and as a potential treatment for a number of...

MetabolomicsPhotosynthetic Carbon Partitioning and Metabolic Regulation in Response to Very-Low and High CO2 in Microchloropsis gaditana NIES 2587
Photosynthetic organisms fix inorganic carbon through carbon capture machinery (CCM) that regulates the assimilation and accumulation of carbon around ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco). However, few constraints that govern the central carbon metabolism are regulated by the ca...

ProteomicsAlgal Protein Kinase, Triacylglycerol Accumulation Regulator1, Modulates Cell Viability and Gametogenesis in Carbon/Nitrogen Imbalanced Conditions
Nutrient-deprived microalgae accumulate triacylglycerol (TAG) in lipid droplets. A Dual-specificity tyrosine phosphorylation-regulated kinase, TAG-accumulation-regulator-1 (TAR1) has been shown to be required for acetate-dependent TAG accumulation and degradation of chlorophyll and photosynthesis-re...

ProteomicsPhosphoproteomics of Chlamydomonas reinhardtii in photoautotrophic nitrogen-deficient conditions
Nutrient-deprived microalgae accumulate triacylglycerol (TAG) in lipid droplets. A dual-specificity tyrosine phosphorylation-regulated kinase, TAG accumulation regulator 1 (TAR1) has been shown to be required for acetate-dependent TAG accumulation and the degradation of chlorophyll and photosynthesi...

TranscriptomicsTranscription profiling by array of Mycobacterium smegmatis response to nitrogen stress using bipartite active modules
BACKGROUND: The ability to adapt to environments with fluctuating nutrient availability is vital for bacterial survival. Although essential for growth, few nitrogen metabolism genes have been identified or fully characterised in mycobacteria and nitrogen stress survival mechanisms are unknown. RESUL...

TranscriptomicsCarbon availability triggers the decomposition of plant litter and assimilation of nitrogen by an ectomycorrhizal fungus
Abstract: A large part of the nitrogen in forest soils is found in recalcitrant organic matter-protein complexes. Ectomycorrhizal fungi are thought to have a key role in the decomposition and mobilization of nitrogen from such complexes. The knowledge on the functional mechanisms of these processes,...

TranscriptomicsNext generation sequencing of Phaeodactylum tricornutum grown with and without nitrogen
We have done next generation sequencing of optically thin, exponentialy growing Phaeodactylum tricornutum cultures grown with and without nitrogen source to improve our undestanding of the pathways regulation under conditions that promote lipid accumulation (N-starvation). 3 biologically independent...

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...
