Interactions among mutations that cause altered timing of gene expression during sporulation in Bacillus subtilis.

Abstract excerpt

The ski4::Tn917lac insertion mutation in Bacillus subtilis was isolated in a screen for mutations that cause a defect in sporulation but that are suppressed by the presence or overexpression of the histidine protein kinase encoded by kinA (spoIIJ). ski4::Tn917lac caused a small defect in sporulation, but in combination with a null mutation in kinA, it caused a much more severe defect. The insertion mutation was...
