RpoS encodes

Another gene, which is required for cellulose biosynthesis is rpoS (Romling et al. 1998b, 2000). RpoS encodes for the second principal sigma factor in stationary phase, conferring survival properties to various stresses (Hengge-Aronis 1999). As in the case of csgD, rpoS is solely required for the transcriptional activation of adrA,...
