MetabolomicsA Phosphate starvation response gene (psr1-like) is present in Micromonas pusilla and other marine algae and coordinates the metabolic response to phosphate deficiency
Both marine phytoplankton and terrestrial plants have to deal with limited bioavailability of the key life nutrient, phosphate. In freshwater algae and plants, a phosphate starvation response gene (psr1) has been characterized, which encodes for a transcription factor that regulates the metabolic re...

ProteomicsThe human innate immune protein calprotectin elicits a multi-metal starvation response in Pseudomonas aeruginosa
To combat infections, the mammalian host limits availability of essential transition metals such as iron (Fe), zinc (Zn), and manganese (Mn) in a strategy termed “nutritional immunity”. The innate immune protein calprotectin (CP) contributes to nutritional immunity by sequestering these metals to ex...

ProteomicsLinking the transcriptome to physiology: response of the proteome of Cupriavidus metallidurans to changing metal availability
Cupriavidus metallidurans CH34 is a metal-resistant bacterium. Its metal homeostasis is based on a flow equilibrium of metal ion uptake and efflux reactions, which adapts to changing metal concentrations within an hour. At high metal concentrations, up-regulation of the genes for metal efflux system...

GenomicsGenome-Wide Characterization of the Phosphate Starvation Response in Schizosaccharomyces pombe [ChIP-Seq data]
Inorganic phosphate is an essential nutrient required by organisms for growth. During phosphate starvation, Saccharomyces cerevisiae activates the phosphate signal transduction (PHO) pathway leading to the expression of the secreted acid phosphatase, PHO5. The fission yeast, Schizosaccharomyces pomb...

TranscriptomicsExpression data from Arabidopsis thaliana under phosphate starvation stress
We performed a transcriptomic analysis of Pi starvation responses in Arabidopsis thaliana (Columbia-0) wild type plants under phosphate starvation stress and in plants with altered PHR1(-like) activity, comparing mutants of phr1 and phr1-phl1 grown in phosphate-lacking medium. Results show the centr...

ProteomicsProteomic analysis reveals global iron starvation response to metal mixture exposure in a Bacillus cereus strain native to a heavy metal contaminated site
Globally, multiple heavy metal contamination is an increasingly common problem. As heavy metals have the potential to disrupt microbially-mediated biogeochemical cycling, it is critical to understand their impact on microbial physiology. However, systems-level studies on the effects of a combination...

TranscriptomicsExpression data from Arabidopsis thaliana PHR1 primary targets genes under phosphate starvation stress
We performed a transcriptomic analysis of Pi starvation responses in Arabidopsis thaliana (Columbia-0) phr1 mutant plants expressing PHR1 in presence of cicloheximide, that inhibit protein translation, thus preventing any effect of PHR1 on the expression of indirect targets. Results show the primary...
