MetabolomicsPronounced uptake and metabolism of organic substrates by diatoms revealed by pulse-labeling metabolomics
Diatoms contribute as a major group of microalgae to approximately 20% of the global carbon fixation. In the plankton, these algae are exposed to a plethora of metabolites, especially when competing algae are lysed. In line with evidence that these phototrophs can also engage in heterotrophy we aske...

MetabolomicsMembrane lipid as cofactor of cargo uptake and release by box-like lipid transfer proteins
Lipid transfer proteins (LTPs) shuttle their cargo lipids between cellular membranes. LTPs facilitate the costly extraction of a lipid from a donor membrane, and its delivery into the acceptor membrane, but the mechanisms remain poorly understood. We combined extensive molecular dynamics simulations...

MetabolomicsIntegrated Physiological and Multi-Omics Analyses Reveal Nitrogen Fertilization Promotes Salix matsudana Growth and Soil Remediation

Soil contamination with heavy metals, particularly lead (Pb) and cadmium (Cd), has become a growing environmental concern due to rapid industrialization. Salix matsudana, a woody energy plant with notable tolerance to heavy metals, exhibits considerable potential for use in phytoremediation...

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...

TranscriptomicsIron uptake experiments in yeast
The budding yeast S. cerevisiae responds to depletion of iron in the environment by activating Aft1p, the major iron-dependent transcription factor, and by transcribing systems involved in the uptake of iron. Here we have studied the transcriptional response to iron deprivation, and have identified ...

TranscriptomicsNitrogen-efficient rice over-expressing alanine aminotransferase
Oryza sativa cv. Nipponbare was engineered to over-express a barley alanine aminotransferase (alaAT) gene using the promoter (OsANT1) from a rice aldehyde dehydrogenase gene that expresses in roots. We are using biotechnology to improve the nitrogen use efficiency of rice by over-expressing alaAT in...

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...

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...

ProteomicsThe signal transduction protein PII controls ammonium, nitrate and urea uptake in cyanobacteria
PII signal transduction proteins are widely spread among all domains of life where they regulate a multitude of carbon and nitrogen metabolism related processes. Non-diazotrophic cyanobacteria can utilize a high variety of organic and inorganic nitrogen sources. In recent years, several physiologica...
