FIG. 1.

Sequence relationships among B. burgdorferi B31 MI linear plasmid lp21 and chromosomal right telomeric regions. Shading of the chromosomal and plasmid DNAs represented by rounded bars indicates the following: solid black, the constant portion of the chromosome (which extends from the left chromosomal end through gene BB0843); dark gray, the right-end extension on the B31 chromosome and very similar sequence on the Sh-2-82 chromosome; white, the unique (non-63-bp repeat) regions of B31 plasmid lp21 and the very similar sequence on the Sh-2-82 chromosome; hatched, the region of 63-bp tandem repeats on lp21 and similar sequence on the Sh-2-82 chromosome. Gray areas between DNAs highlight regions of similarity between adjacent DNAs; the darker gray (and percent values there) indicate similarities to sequence determined in this study. Black arrows indicate putative intact genes (pseudogenes are not shown). Numbered black bars show the locations of DNA probes used in this study (also Table 1). The Sh-2-82 nucleotide sequences determined here are indicated by open bars immediately above the kilobase pair scale, whose zero point is the right end of the constant portion of the chromosome.
