Salmonella enterica displays the pdar (pink, dry and rough) morphotype on agar containing Congo Red which reflects the production of extracellular matrix components cellulose and curli fimbriae. In this issue, Fang et al . identify the BcsE protein as a novel c‐di‐GMP‐binding protein required for maximal cellulose production. For further details readers are referred to the article by Fang et al . on pp. 439–452 of this issue [This caption was revised on 6 Aug 2014.]
