Schematic representation of multiple rearrangements in subpopulations of Rhizobium sp. NGR234. CFNX503 and its derivative CFNX505 are subpopulations pure for specific rearrangements (see text). The position of reiterated sequences (□, NGRIS5b; ■, NGRIS5c; ○, NGRIS2a; and ●, NGRIS2b) of recombinant structures (╡ and ◑) and of PCR primers (1, NGRIS5b FP; 2, NGRIS5b RP; 3, NGRIS5c FP; 4, NGRIS5c RP; a, NGRIS2a FP; b, NGRIS2a RP; c, NGRIS2b FP; and d, NGRIS2b RP) are indicated. A, B, and C correspond to the AMPLs described in the text.
