Comparative genomic analysis of the extrachromosomal replicons of H. hispanica and H. marismortui. The orc/cdc6 genes (those from H. hispanica and H. marismortui are highlighted with a purple asterisk and a dark green round dot, respectively) that are associated with candidate replication origins are indicated, and the shared origins associated with cdc6G/cdc6a, cdc6K/cdc6k of the two strains are highlighted in bold. The homologous regions are boxed, and the lines in the box represent the regions that are continuous in H. marismortui.
