Abstract Down- and up-shift responses of a mutant colony of strain BIB1416 (Δald , PtrpE-mCherry) and a non-fluorescent WT colony BIB224. Both strains were starved in co-culture on an SM* gel pad and show comparable sporulation dynamics. After sporulation is complete, spore revival was induced with L-alanine. Both mutant and WT spores show comparable germination. However, only WT spores grew out while the mutant spores did not.
