TranscriptomicsGene expression timecourse in M-NM-^TrpaA strain
The goal of the experiment was to determine whether gene expression oscillates in the absence of rpaA. It was reported previously (e.g., Takai et al, PNAS 2006) that activity of a handful of individual expression reporters was arrythmic, and we conducted this microarray timecourse to determine whet...

TranscriptomicsGene expression timecourse in wild-type strain
The goal of the experiment was to obtain a replicate of the wild-type LL circadian timecourse published in Vijayan et al, PNAS 106: 22564-22568 (2009), in order to identify reproducible circadian genes in LL. Cultures were grown in a turbidostat as described previously (Vijayan et al, PNAS 2009), ex...

TranscriptomicsComparison of gene expression in M-NM-^TrpaA strain and wild-type strain
The goal of the experiment was to determine the difference in gene expression between the wild-type strain and a strain lacking rpaA (M-NM-^TrpaA). Because gene expression is not at steady-state in the wild-type -- it oscillates with a circadian period -- and we did not know a priori whether it is ...

TranscriptomicsGene expression timecourse in clock rescue strains
The goal of this experiment was to determine whether global circadian gene expression oscillation depends strictly on the presence of rpaA, even when the KaiABC post-translational oscillator is oscillating with a circadian period. Strains deleted for rpaA lack functional KaiABC post-translational o...

TranscriptomicsA high resolution map of a cyanobacterial transcriptome
Previous molecular and mechanistic studies have identified several principles of prokaryotic transcription, but less is known about the global transcriptional architecture of bacterial genomes. Here we perform a comprehensive study of a cyanobacterial transcriptome, that of Synechococcus elongatus P...

TranscriptomicsOscillations in supercoiling drive circadian gene expression in cyanobacteria
The cyanobacterium Synechococcus elongatus PCC 7942 exhibits oscillations in mRNA transcript abundance with 24-hour periodicity under continuous light conditions. The mechanism underlying these oscillations remains elusive â?? neither cis nor trans-factors controlling circadian gene expression phase...

TranscriptomicsJuvenile rainbow trout exposed in situ at site receiving different concentrations of municipal wastewater effluent (MWWE) and an upstream reference site
Juvenile rainbow trout were exposed to MWWE in a caging study, with cages held upstream and downstream of a MWWE outfall for two weeks in the fall of 2007. Whole tissues were sampled and analyzed. Microarray analysis was conducted on liver samples. Four condition experiment, Control (0%),10%, 50% an...
