Variation of beta-galactosidase expression from Mudlac elements during the development of Escherichia coli colonies.

Annales de l'Institut Pasteur. Microbiology - 1 Jan 2000

Shapiro J A, Higgins N P

Abstract excerpt

Bacterial colonies reveal the action of systems for multicellular regulation of genetic activity during growth and development. Colonies produced on agar indicator medium by Escherichia coli strains carrying the transposable genetic fusion element Mudlac displayed organized patterns of differential beta-galactosidase expression. One feature of these patterns was the presence of phenotypically distinct concentric...
