TranscriptomicsHalobacterium NRC-1 VNG1451C deletion mutant growth in defined medium with and without glucose
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 hav...

TranscriptomicsRole of σ54 in the regulation of genes involved in biogenesis of type I and type IV pili in Xylella fastidiosa
The phytopathogen Xylella fastidiosa produces two classes of pili, long type IV pili and short type I pili, which are involved in motility and adhesion. In this work, we have investigated the role of σ54 factor and its involvement in the regulation of fimbrial biogenesis in X. fastidiosa. An rpoN n...

TranscriptomicsGene expression during germination in the Chytridiomycete Blastocladiella emersonii
To investigate global changes in gene expression during B. emersonii germination process, we constructed cDNA microarrays containing 3,563 putative unique genes. Analyses were carried out during germination induced under various environmental conditions. Microarray data revealed that 26% of them are...

TranscriptomicsHalobacterium salinarum NRC-1 total RNA hybridization of TFBd overexpression versus Reference sample
Total RNA hybridizations of Halobacterium salinarum NRC-1 total RNA versus a strain overexpressing TFBd were compared to verify the transcriptome landscape changes. Comparison with TFBd binding sites localized using ChIP-chip data and MeDiChI algorithm (Reiss et al, 2008) allowed observation that TF...

TranscriptomicsHalobacterium sp. NRC-1 ChIP-chip for TFBa, TFBd and TFBf, high resolution array
A detailed map of genomic locations where TFs bind DNA and modulate transcription is essential to model mechanisms of gene regulation on a systems-scale. Chromatin immunoprecipitation of transcription complexes coupled to microarray (ChIP-chip (Ren et al, 2000)) or sequencing (ChIP-seq (Robertson et...

TranscriptomicsHalobacterium salinarum NRC-1 growth curve
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 l...
