Genes for small, noncoding RNAs under sporulation control in Bacillus subtilis.

ABSTRACT: The process of sporulation in the bacterium Bacillus subtilis is known to involve the programmed activation of several hundred protein-coding genes. Here we report the discovery of previously unrecognized genes under sporulation control that specify small, non-protein-coding RNAs (sRNAs). Genes for sRNAs were identified by transcriptional profiling with a microarray bearing probes for intergenic regions in the genome and by use of a comparative genomics algorithm that predicts regions of conserved RNA secondary structure. The gene for one such sRNA, SurA, which is located in the region between yndK and yndL, was induced at the start of development under the indirect control of the master regulator for entry into sporulation, Spo0A. The gene for a second sRNA, SurC, located in the region be
