Putative diagram of sporulation and germination events in D. hafniense DCB-2. The proposed genes are based on known developmental and genetic processes of sporulation and germination in Bacillus and Clostridium species. A brief description for each developmental stage and the genes encoding stage-specific enzymes or structural proteins are depicted. Compartment-specific sigma factors are also indicated. Gene homologs in D. hafniense DCB-2 were identified by using BLASTP with cutoff values of 1e-2 (E-value) and 30% identity in amino acid sequence.
