FIG. 2.

The R. etli CE3 lps α and lps-166 genetic regions. The lps α locus is a contiguous stretch of DNA shown on the left. The dotted line indicates that lps-166 is separated from the lps α locus by an undetermined distance along the chromosome. Ticks on the upper line indicate the positions of EcoRI sites. The relative locations of the Tn5 insertions of four mutants in this study are indicated by arrows above this line. The lines below indicate stretches of DNA from lps α that are contained in the specified plasmids. The lps α DNA responsible for the suppression of lps-166 is located in the region indicated by the striped box.
