FIG 5.

Dynamics of chromosome replication during the B. bacteriovorus life cycle. B. bacteriovorus (orange) attacks and invades the host cell (gray). Chromosome replication (green replisome) is initiated at the invasive pilus-proximal pole. The dotted line and greyscale represent the speculated alternative B. bacteriovorus life cycle conducted in two independent host cells. The inner circle diagram represents the periods of the bacterial cell cycle as follows: B, the time between progeny formation and the initiation of chromosome replication in daughter cells; C, chromosome replication; and D, the time between the termination of replication and the completion of filament septation. t = 0 min refers to the bdelloplast formation. The listed time points were calculated in this study.
