Expression pattern of different sigma factors in strains with enhanced spoIIG transcription in the prespore

a Cultures were induced to form spores in MSSM.

b Strains were either csfB⁺ or csfB null (−).

c Samples were analyzed at the indicated times given in hours after the start of spore formation.

d All strains were spoIIG⁺ and also contained amyE::P_spoIIQ-spoIIG to enhance early transcription of spoIIG in the prespore. Schematic representations are given of the different types of organism present in the cultures; shaded areas indicate GFP fluorescence. Membranes were visualized by staining with FM4-64.
