pHRC017 confers a competitive advantage for nodule occupancy and is genetically similar to other HR plasmids (large accessory plasmids affecting symbiotic host range). A, The competitive indexes for C017 and C017-GOC (a gain-of-compatibility derivative) grown in competition when inoculated onto a compatible host (M. italica; n = 3), onto an incompatible host (M. truncatula [M. t.] A17; n = 6), or into LB (Luria broth; n = 6). Error bars represent standard error of the mean. The HR plasmid in C017 was modified with the oriT/neo cassette to permit transfer and selection. B, Diagram and annotation of pHRC017. Conservation of sequence in other HR plasmids (based on polymerase chain reaction tests) is indicated by + or −.
