title: Periseptal annuli: organelles involved in the bacterial cell division process.
abstract: Specialized structures (periseptal annuli) appear at future cell division sites long before the division septum is formed. Studies of their biogenesis and localization are providing unexpected insights into the earlier stages of localization and differentiation of the division site.
