TABLE 2.
IS-like elements isolated from B. japonicum HRS strains
| IS element | Length (kb) | TIRa | Source | Sequence with highest level of homologyb (accession no.) | % of DNA homologyb | IS familyc |
|---|---|---|---|---|---|---|
| IS1631 | 2.7 | 41/53 | T2 | Alcaligenes eutrophus DR2 (D64144) | 55.0 | IS21 (IS3) |
| IS1632 | 1.4 | 34/44 | NK5 | Burkholderia cepacia IS1413 (U58191) | 60.0 | IS256 |
| RSα (ISB12) | 1.2 | 5/5 | NK5 | Bradyrhizobium japonicum RSRjα9 (M10925) | 97.8 | IS630-Tc1 |
| RSβ (ISB14B) | 1.4 | 17/22 | T2 | Shigella dysenteria IS911 (X17613) | 57.5 | IS3 |
| ISB20 | 2.0 | 22/26 | T2 | Bradyrhizobium japonicum 123 HRS1 (L09226) | 95.0 | |
| ISB27B | 2.7 | 17/23 | NC3a | Agrobacterium tumefaciens IS866 (M25805) | 63.1 | |
| FK1 | 0.8 | NK5 | Pseudomonas cepacia IS401 (U84154) | 58.3 | IS21 (IS3) |

Number of identical residues/total number of residues.

The DDBJ/EMBL/GenBank database was searched for homologies to the IS sequences; the maximum percentage of homology is shown. The entire sequences of IS1631, IS1632, and FK1 were available in the database. We have not determined the complete sequences of ISB12 (RSα), ISB14B (RSβ), ISB20, and ISB27B. Therefore, when the percentage of homology differed between the left and right sides of the IS element, the higher value is shown.
