摘要

The positioning of constrictions in Escherichia coli filaments pinching off anucleate cells was analyzed by fluorescence microscopy of dnaX(Ts), dnaX(Ts) sfiA, dnaA46(Ts), gyrA(Am) supF(Ts), and gyrB(Ts) mutants. In filaments with actively replicating nucleoids, constrictions were positioned close to the nucleoid, whereas in nonreplicating filaments, positioning of constrictions within the anucleate region was nearly random. We conclude that constriction positioning depends in an unknown way on nucleoid replication activity.
