Dormant and SD PS533 (wild-type) and FB10 (gerBB*) spores were isolated as described in Materials and Methods, with SD spores being prepared by germination with l-valine or AGFK (PS533 spores) or l-asparagine (FB10 spores). The dormant and SD spores were germinated with l-valine, AGFK, or l-asparagine, and the percentage of spores that germinated in 2 h was determined by phase-contrast microscopy as described in Materials and Methods. NT, not tested.
PS533 spores.
FB10 spores.
