Dynamic map of the pSym of Rhizobium sp. NGR234 (pNGR234a). The position and orientation of reiterated DNA sequences are indicated by arrowheads. The origin of replication (oriV) and the first and last bases of the annotation of the sequence as reported previously (9) are indicated. The different AMPLs are represented by arcs outside the plasmid circle. 1, AMPL Rhizobium sp. NGR234 IS5a-b; 2, AMPL Rhizobium sp. NGR234 IS5a-c; 3, AMPL Rhizobium sp.
