| Description |
Growth and sporulation in DSM Replicate 2: A wild-type PY79 culture was grown in Difco Sporulation Medium. Samples were taken at 2.5 (OD600nm 0.4), 2 (OD600nm 0.6), 1.5 (OD600nm 1.3), 1 (OD600nm 1.9), and 0.5 (OD600nm 2.2) hours before the onset of stationary phase, the onset of stationary phase (OD600nm 2.4), and 0.5 (OD600nm 2.5), 1 (OD600nm 2.5), 1.5 (OD600nm 2.5), 2 (OD600nm 2.3), 2.5 (OD600nm 2.4), 3 (OD600nm 2.4), 3.5 (OD600nm 2.4), 4 (OD600nm 2.5), 4.5 (OD600nm 2.5), and 5 (OD600nm 2.8) hours after the onset of stationary phase. A common reference was made by pooling RNA from each time point.

| Data processing |
Microarray data processing was performed in R (www.r-project.org) using the Bioconductor bioinformatics software package (www.bioconductor.org). Data were loaded into R using the marray package and normalized between arrays using loess normalization. Normalized log-ratios of gMedianSignal and rMedianSignal were collapsed for redundant probes taking the average.
