Key result
Expression of the Bacillus subtilis spoIVB gene can be transcribed by RNA polymerase associated with either sigma F or sigma G, though only sigma G directs significant levels during sporulation.
The expression of the Bacillus subtilis spoIVB gene, which encodes a developmental cell-cell signalling molecule, has been characterized. In some conditions, this gene can be transcribed by RNA polymerase associated with either sigma F or sigma G, in contrast to previous studies implying exclusive control by sigma G. However, during sporulation, only sigma G directs significant levels of spoIVB expression.

Gómez et al. (1996) studied Bacillus subtilis gene expression. Expression of the Bacillus subtilis spoIVB gene can be transcribed by RNA polymerase associated with either sigma F or sigma G, though only sigma G directs significant levels during sporulation.
