| Description |
Growth and sporulation in DSM Replicate 1: A wild-type PY79 culture was grown in Difco Sporulation Medium. Samples were taken at 1.5 (OD600nm 1.0), 1 (OD600nm 1.3), and 0.5 (OD600nm 1.7) hours before the onset of stationary phase, the onset of stationary phase (OD600nm 1.9), and 0.5 (OD600nm 1.9), 1 (OD600nm 2.3), 1.5 (OD600nm 2.2), 2.5 (OD600nm 2.3), 3.5 (OD600nm 2.0), 4 (OD600nm 2.3), 4.5 (OD600nm 2.6), 5 (OD600nm 2.7), and 5.5 (OD600nm 2.9) 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.
