FIG. 4.

Effect of 1 mM inosine on the germination of spores of the wild-type strain and the gerR, gerI, and gerQ mutants. •, wild-type strain; ▵, gerQ spores; ▿, gerI spores; ○, gerR spores; ⋄, wild-type strain with no germinant. Spores of these mutants showed reduced germination rates compared to that of the wild type, although the spores of these strains were able to complete germination within 60 min. The responses of gerG, gerK, gerL, and gerS spores were coincident with those of wild-type spores.
