TABLE 4.

Germination of initial and superdormant spores prepared with moderate germinant concentrations by germinants targeting different germinant receptors^a

Spore used	SD spore prepn	Germination in	Spore germination (%/2 h)
			SD	Initial
B. subtilis wt	300 μM l-val	1/4 AGFK	<3	40
B. subtilis wt	300 μM l-val	AGFK	65	80
B. megaterium	200 μM d-glucose	250 μM l-pro	<5	40
B. megaterium	200 μM d-glucose	10 mM l-pro	80	90

^aSuperdormant spores of B. subtilis wild-type (PS533) and B. megaterium were prepared with moderate germinant concentrations, initial and superdormant spores were germinated with either a moderate or the normal high germinant concentration targeting a different germinant receptor(s) than that targeted in superdormant spore isolation, and extents of spore germination after 2 h of incubation were determined, as described in Materials and Methods. SD, superdormant; wt, wild type; l-val, l-valine; l-pro, l-proline.
