Overview of Bacillus subtilis Atomic Regulons (ARs). (A) Expression data used for AR inference in B. subtilis (Buescher et al., 2012; Nicolas et al., 2012). (B) Categorization of genes in ARs. Genes have been categorized based on the expression profile as always “ON”, always “OFF” and differentially expressed. (C) Gene function for genes always “ON” and “OFF”. B. subtilis 168 genes are classified in SubtiWiki (Florez et al., 2009; Mader et al., 2012) into 6 categories cellular function; here we show the fraction of genes in the “always ON” regulon (right) and the “always OFF” regulon (left) that occur in each category.
