Annotation of <i>R. felis</i> large (pRF) and small (pRFδ) plasmid-encoded genes that are absent on the <i>R. felis</i> chromosome, and their distribution in other rickettsiae, other bacterial sequences, and other non-bacterial taxa.

a<p>ORF labels that are bolded depict putative genes that are unknown from other published rickettsiae genomes.</p>b<p>AG = ancestral group, TG = typhus group, TRG = transitional group, SFG = spotted fever group, bac = present (y) or absent (n) in a diverse array of non-rickettsial bacteria, or present in a few (f) bacteria, nb = present (y) or absent (n) in non-bacterial organisms. Presence (y) or absence (n) of putative orthologs found in other plasmids (pl) are listed. Br = <i>R. bellii</i> str. RML369-C, Bo = <i>R. bellii</i> str. OSU 85 389, Ca = <i>R. canadensis</i> str. McKiel, Pr = <i>R. prowazekii</i> str. Madrid E, Ty = <i>R. typhi</i> str. Wilmington, Ak = <i>R. akari</i> str. Hartford, Fe = <i>R. felis</i> str. URRWXCal2, Ri = <i>R. rickettsii</i>, Co = <i>R. conorii</i> str. Malish 7, and Si = <i>R. sibirica</i> str. 246. r = reduced gene relative to the plasmid gene, t = truncated gene relative to the plasmid gene, s = split gene relative to the plasmid gene.
