Cluster of Orthologous Groups (COG) functional categories of genes induced and repressed under different conditions. Each bar represents the number of DEGs in each category in the B. subtilis natto genome. Orange bars indicate genes repressed at 9 th h relative to 6 th h; The diagonal orange bars indicate 9th h significantly up-regulated genes relative 6 th h. Blue bars indicate genes repressed at 24 th h relative to 6 th h and the diagonal Blue bars indicate 9 th h significantly up-regulated genes relative 6 th h. Yellow bars indicate genes repressed at 24 th h relative to 9 th h and the diagonal yellow bars indicate 24 th h significantly up-regulated genes relative 9 th h
