Identification of Genes in the σ²²Regulon of Pseudomonas aeruginosa Required for Cell Envelope Homeostasis in Either the Planktonic or the Sessile Mode of Growth

Abstract excerpt

UNLABELLED: The Pseudomonas aeruginosa extracytoplasmic functioning (ECF) sigma factor σ(22) is encoded by algT/algU and is inhibited by anti-sigma factor MucA. σ(22) was originally discovered for its essential role in the expression of the exopolysaccharide alginate by mucoid strains associated with chronic pulmonary infection. However, σ(22) is now known to also have a large regulon associated with the response...
