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...

MetabolomicsOrganotypic microfluidic breast cancer model reveals starvation-induced spatial-temporal metabolic adaptations
BACKGROUND: Ductal carcinoma in situ (DCIS) is the earliest stage of breast cancer. During DCIS, tumor cells remain inside the mammary duct, growing under a microenvironment characterized by hypoxia, nutrient starvation, and waste product accumulation; this harsh microenvironment promotes genomic in...

TranscriptomicsGenome-Wide Characterization of the Phosphate Starvation Response in Schizosaccharomyces pombe [gene expression 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...

TranscriptomicsThe response and recovery of Arabidopsis thaliana transcriptome to phosphate starvation [At35b_MR]
Background: Over application of phosphate fertilizers in modern agriculture contaminates waterways and disrupts natural ecosystems. Nevertheless, this is a common practice among farmers, especially in developing countries as abundant fertilizers are believed to boost crop yields. The study of plant ...

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...

TranscriptomicsDiversity in the complexity of phosphate starvation transcriptomes among rice cultivars based on RNA-Seq profiles
Rice has developed several morphological and physiological strategies to adapt to phosphate starvation stress. In order to elucidate the molecular bases of response due to phosphate stress particularly the transcriptional profile of genotypes with variation in tolerance to phosphate starvation, we a...

TranscriptomicsA novel phosphate-starvation response in fission yeast requires the endocytic function of Myosin I (RNA-seq)
S. pombe Myosin I (MyoI) plays a key role in cytoskeletal functions, in particular it is part of the endocytotic machinery. Here we show a novel role for MyoI in regulating the response to low phosphate stress. Deletion of MyoI led to an increased proliferation in low phosphate media when compared t...
