Spore development in Bacillus subtilis.
Cell-cell and starvation signals are funneled through the phosphorelay to initiate sporulation by activating the transcription regulator SpoOA. Activation of SpoOA leads to synthesis of the transcription factors sigmaF and sigmaE. Substantial advances have been made in our understanding of the signal circuitry of the phosphorelay and of the cell-type-specific activation of the sigma factors.
