Fis occupancy along the Salmonella enterica serovar Typhimurium SL1344 fis::3XFlag strain grown in different aeration regimes.


ABSTRACT: The regulatory role of the Fis protein in fis and in the transcription of several gene regions during mid-exponential and late-stationary phase, and during different growth aeration regimes, has been investigated. Studies were done during those two growth phases and in aerated and non-aerated (microaerobic) conditions, to measure Fis enrichment and binding peaks in strategic gene regions by genome-wide microarray analysis ChIP-chip. This research investigation points to central roles for SPI-1, SPI-2, DNA gyrase and topoisomerase I, the elements of the stringent response, and the regulatory function of Fis-binding patterns, in setting and re-setting the activity of the fis gene and other involved promoters as a function of the growth conditions and aeration regimes experienced by Salmonella. One sample with four different treatments. Three biological replicates per sample. The Aerated 2 hour sample was set as the control condition for all samples.
