Twenty-five randomly selected Bradyrhizobium japonicum BAC clones digested with XbaI. (A) Ethidium bromide-stained CHEF gel (5–15 sec switch time, 15 h) showing insert DNA above and below the 6-kb pBACindigo XbaI vector fragment band. (B) Autoradiograph of gel in A after Southern transfer and probing with total B. japonicum genomic DNA. Molecular markers (New England Biolabs) are λ ladder (insidelane) and 1-kb DNA ladder (outside lane).
