The strain BIB1019 carries PtrpE*-mCherry and PspoIIE-gfp reporters. After 90 h of starvation, spores have been released from the mother cell. To visualize the distribution of early and late spores prior to the nutrient up-shift, false colored frames were included with early and late spores denoted in yellow and green, respectively. Note that most spores geminated but only early spores succeed in resuming vegetative growth. Spores that grew out upon nutrient stimulation are circled in red.
