Bidirectional best hits (BDBHs) were calculated in pairwise comparisons using BLASTP. All reciprocal matches with e-value up to 1e-04 and a coverage of at least 50% on the length of the shorter CDS were collected. p42d, the symbiotic plasmid of R. etli, 371 kb, 359 CDS; pNGR234a, the symbiotic plasmid of Rhizobium sp. 536 kb, 416 CDS; SGCBj, B. japonicum USDA110 symbiotic chromosomal region, 410 kb, 388 CDS; SmChr, S. meliloti chromosome, 3,600 kb, 3396 CDS; pSymA, S. meliloti symbiotic plasmid A, 1,354 kb, 1,295 CDS; pSymB, S. meliloti symbiotic plasmid B, 1,683 kb, 1,571 CDS; MlChr, M. loti MAFF303099 chromosome without the symbiotic island, 6,425 kb, 6,172 CDS; pMLa, M. loti MAFF303099 cryptic plasmid a, 351 kb, 320 CDS; pMLb, M. loti MAFF303099 cryptic plasmid b, 208 kb, 209 CDS; SGCMl, M. loti MAFF303099 symbiotic island, 611 kb, 580 CDS; SGCR7A, M. loti R7A symbiotic island, 502 kb, 414 CDS. ND, not determined. *The number of BDBHs with the complete genome of B. japonicum USDA110 is 150.
