Project description:Gene regulatory networks play an important role in coordinating biochemical fluxes through diverse metabolic pathways. The modulation of enzyme levels enables efficient utilization of limited resources as organisms dynamically acclimate to nutritional fluctuations in their environment. Here we have identified and characterized a novel nutrient-responsive transcription factor from the halophilic archaea, VNG1451C. In this experiment we used whole-genome microarray analysis in the VNG1451C deletion mutant vs. H. salinarum NRC-1 ura3 parent strain in rich medium during growth to show that the expression of many metabolic genes is perturbed in the VNG1451C deletion mutant. Halobacterium salinarum NRC-1 (ATCC700922) ura3 parent and VNG1451C strains were grown in complex medium (CM; 250g/L NaCl, 20g/L MgSO4.7H2O, 3g/L sodium citrate, 2g/L KCl, 10g/L peptone) at 37ºC under full-spectrum white light. Biological replicate samples were removed throughout the growth curve at early log, mid log, late log, and stationary phase to measure genome-wide transcription.

Project description:We set out to determine a) if histone in Halobacterium salinarum regulates transcription and b) whether the magnitude and extent of these changes matches those observed in organisms which use histone protein as their primary DNA packaging agent. To this end, gene expression data for a histone knock-out (?ura3?hpyA) strain versus parent (?ura3) were collected. The histone deletion mutant and parent strain, at log and stationary phase, were compared to the common reference strain NRC-1 (log). There are three biological replicates each, plus dye-flips, for a total of 24 arrays

Project description:Gene regulatory networks play an important role in coordinating biochemical fluxes through diverse metabolic pathways. The modulation of enzyme levels enables efficient utilization of limited resources as organisms dynamically acclimate to nutritional fluctuations in their environment. Here we have identified and characterized a novel nutrient-responsive transcription factor from the halophilic archaea, VNG1451C. In this experiment we used whole-genome microarray analysis in the VNG1451C deletion mutant vs. H. salinarum NRC-1 ura3 parent strain in defined medium during growth with and without glucose to show that the expression of many metabolic genes is perturbed in the VNG1451C deletion mutant in response to this sugar. Halobacterium salinarum NRC-1 (ATCC700922) ura3 parent and VNG1451C strains were grown in complete defined medium (CDM; 20 amino acids at concentrations defined by Shand and Perez, 1999. NaCl 250g/L, MgSO4 20 g/L, KCl 1 g/L, NaH2PO4 0.167mM, Biotin 0.02mM, Thiamin 0.015mM, Folic acid 0.0113 mM, MnSO4 0.01mM, FeSO4, 0.01mM, glucose added at 10% w/v where indicated in sample files) at 37ºC under full-spectrum white light. Biological replicate samples were removed throughout the growth curve at early log, mid log, and stationary phase to measure genome-wide transcription.

Project description:Halobacterium salinarum NRC-1 was grown in CM media, at 37oC in a waterbath with agitation of 125 rpm under constant light. Analysis of transcriptional changes during growth, in addition to mapping of transcriptome structure under the same conditions, provided interesting insights about regulatory logic within prokaryotic coding regions.
