Expression of genes coding for germination receptors in strains with prpE deleted, detected by using a β-galactosidase reporter. (A) Solid bars, 168; open bars, MM1604 (gerA-lacZ); shaded bars, MM1607 (gerA-lacZ ΔprpE). (B) Solid bars, 168; open bars, MM1615 (gerB-bgaB); shaded bars, MM1616 (gerB-bgaB ΔprpE). (C) Solid bars, 168; open bars, MM1618 (gerK-bgaB); shaded bars, MM1619 (gerK-bgaB ΔprpE). Bacteria were grown in Sterlini-Mandelstam medium at 37°C with shaking. At time zero, sporulation was initiated by replacing Sterlini-Mandelstam growth medium with sporulation medium. The bgaB gene is functionally equivalent to lacZ. ONP, o-nitrophenyl.
