Growing pains: natural stress response during growth of B. subtilis (high density time-resolved transcriptome analysis)

ABSTRACT: We have determined the time-resolved transcriptome of the model gram-positive organism B. subtilis during growth on rich medium. DNA microarrays were used to monitor gene transcription in 10-minute intervals at 40 consecutive timepoints. From the growth curve and a PCA analysis of all gene expression levels, we identified 4 distinct growth phases: a lag phase, an exponential growth phase, and very clearly separated early and late stationary growth phases For each time point, labeled cDNA was hybridized to a microarray slide together with labeled cDNA from the previous timepoint. In addition, the same DNA was used in a dye swap hybridization with the labeled cDNA from the subsequent timepoint. Lastly, labeled cDNA from each timepoint was hybridized with labeled cDNA from 30 mins later (e.g.
