FIG. 3.

S. meliloti genomic region containing lpsL and rkpK. The site of the frameshift mutation is denoted with an asterisk. The unshaded region corresponds to the part of LpsL truncated as the result of the premature termination resulting from the frameshift mutation. The numbers correspond to the amino acid positions of the open reading frame. The lines placed below the open reading frame depiction correspond to the regions of lpsL and rkpK carried on the plasmids used for complementation and gene inactivation.
