rial chromosomes have been experimentally demonstrated to replicate unidirectionally. Here, we showed that the chromids (plasmid-derived chromosomes) in Pseudoalteromonas replicate either uni- or bidirectionally and that a single evolutionary transition from uni- to bidirectionality explains this diversity. These uni- and bidirectionally replicating chromids likely represent two stages during the evolution from a small and unidirectionally replicating plasmid to a large and bidirectionally replicating chromosome. This study provides i
