By using phylogenetics, we show that most genes with homologs in both the plasmid and the chromosome have different evolutionary origins. Moreover, we identify related plasmids outside of the genus that are rather large.

This suggests that domesticated plasmids in Pantoea arose from large ancestral plasmids that experienced genome streamlining, similar to that observed in endosymbionts.

These domesticated plasmids have diversified within the genus, where plasmid groups -with different gene content and sizes- coincide with main speciation events.

Devani Romero Picazo Interestingly, plasmid LPP-1 harbours genes that are core in the genus pangenome. Most of these genes encode for transcriptional regulators, suggesting the integration of the plasmid in the host's regulatory network.
