Endospore (hereafter called spore) is a dormant, tough, and non-reproductive structure produced in a lack of nutrients by certain species of bacteria from the Firmicute phylum. Sporulation is tightly linked to cell cycle and involving by temporal and spatial regulation of hundreds genes. It has been suggested more than 500 genes are contributed to sporulation in B. subtilis, and there are certainly more. In our study, we identified four new sporulation genes and their mutants exhibited sporulation abnormal. RNA-seq of mutants compared to wild type during sporulation will reveal the regulation of sporulation related genes in the four mutants, and therefore shed the light to the functional role of the four new sporulation genes.
