TranscriptomicsExpression data from +Pi and -Pi treeatment between WT and spx1spx2 double mutant
Fourteen days plants growth under hydroponic +P condition (200 µM) were treated with +P(200µM) or –P (no phosphate) for another 7 days, shoot of plants from 3 biological repeats were sampled for Affymetrix microarray analysis. We used microarrays to detail the global programme of gene expression und...

TranscriptomicsPtrA is required for coordinate regulation of gene expression during phosphate depletion in a marine Synechococcus
The genome of the marine Synechococcus sp. WH8102 displays a minimal regulatory network yet physiological and molecular responses of this organism are tuned to episodic limitation for nitrogen and phosphorus. Microarray analyses have demonstrated a key role for the two-component regulatory system, P...

TranscriptomicsA conserved two-component signal transduction system controls the response to phosphate starvation in Bifidobacterium breve UCC2003
This work reports on the identification and molecular characterization of a two-component regulatory system (2CRS), encoded by phoRP in Bifidobacterium breve UCC2003, which controls the response to phosphate (Pi) starvation. The response regulator PhoP was shown to bind to the promoter region of pst...

TranscriptomicsMicroarray analysis of phosphate regulation in Synechococcus sp. WH8102
Primary productivity of open ocean environments, such as those inhabited by marine picocyanobacteria Synechococcus sp.WH8102, are often limited by low inorganic phosphate (P). To observe how this organism copes with P starvation, we constructed a full genome microarray and examined differences in ge...

GenomicsPho and Ph, H3K27me3 and Engrailed ChIP-seq data in Drosophila third instar larval brains and disks
Genome-wide binding profile of PcG proteins Pho and Ph, H3K27me3 and Engrailed in Drosophila third instar larval brains and disks, in duplicate, using Illumina HiSeq 2500. The sequence reads that passed quality filters were analyzed. Drosophila third instar larval brains and disks were dissected and...

TranscriptomicsManipulation in phospate levels
The arrays were used to study the effects of modifying phosphate levels in yeast, either through mutation, or chemical manipulation. This study is described in more detail in Ogawa N et al.(2000) Mol Biol Cell 11:4309-21

TranscriptomicsExpression data for 2 obese subjects from the SibPair cohort with a deletion on 16p11.2
We report a highly-penetrant form of obesity, initially observed in 31 heterozygous carriers of a 593kb or larger deletion at 16p11.2 from amongst subjects ascertained for cognitive deficits. Nineteen similar deletions were identified from GWAS data in 16053 individuals from 8 European cohorts; such...

TranscriptomicsPho regulon modulation of Enterohemorrhagic *Escherichia coli* O157:H7 virulence factors
In E. coli the phosphate homeostasis is regulated by the Pst system and the two-component system PhoB/R. Pathogens like E. coli O157:H7 are responsible for many outbreaks and can be found and survive in poor inorganic phosphate (Pi) environments. To understand global EHEC O157:H7 EDL933 strain respo...

TranscriptomicsNutrient-Regulated Antisense and Intragenic RNAs Modulate a Signal Transduction Pathway
The budding yeast Saccharomyces cerevisiae alters its gene expression profile in response to a change in nutrient availability. The PHO-system is a well-studied case in the transcriptional regulation responding to nutritional changes in which a set of genes (PHO genes) is expressed to activate phosp...

TranscriptomicsGenome-wide gene expression profiling of rice Indica cultivar Zhongxian 3037 and mutant phoenix (pho) panicle
phoenix (pho) is a naturally occurring rice (Oryza sativa L.) mutant that exhibits stable inflorescence reversion. Genetic analysis showed that it was not a simple mendelian mutant. In order to find the major genes contributed to the formation of pho, microarray experiments were carried out to analy...
