ORF maps of Borreliella lp17 plasmids. The horizontal bars represent all the sequenced lp17 plasmids; identical background colors indicate regions of homologous DNA in the different plasmids. The bacterial species and organizational subtypes (see text) are indicated by Roman numerals and on the right (without their species component, see text), and isolates that carry each subtype are indicated on the left. Selected genes are indicated by red arrows, and black “X”s mark pseudogenes. PFam numbers [19, 30] are indicated in the boxes above; “U”s in boxes are proteins for which no intact gene is known in B. burgdorferi; “J's” in boxes indicate strain B31 homologous proteins for which there is only one gene in strain B31 (i.e., no PFam number exists); adeC, cspZ and fbn refer to adenine deaminase, complement regulator-acquiring surface protein Z and fibronectin binding protein encoding genes, respectively; selected strain B31 gene names are indicated above its map. Black lines between plasmids mark the locations of inversions. See Additional file 1: Figure S3B for locations of indels within generally homologous regions (e.g., deletions within B31-like sections of VS116 lp17 and PBr lp17)
