The replicon is comprised of the origin of replication (ori) and all of its control elements. The ori is the place where DNA replication begins, enabling a plasmid to reproduce itself as it must to survive within cells (Addgene).
F1 is a phage-derived ori that allows for the replication and packaging of ssDNA into phage particles. Plasmids with phage-derived ori's are referred to as phagemids. The origin of DNA replication of bacteriophage f1 functions as a signal, not only for initiation of viral strand synthesis but also for its termination (GP Dotto et.al, 1984).
Here is a part named f1 ori on MolecularCloud. The information as follows:
