FIG. 4.

Genomic location of the recA gene in strains of the B. cepacia complex. (A) Lanes: M, molecular size standards (S. cerevisiae chromosomes; relevant size bands are indicated in kilobases); 1, strain ATCC 25416 (genomovar I); 2, B. multivorans strain 17616; 3, strain C5424 (recA group III-A); 4, strain C1394 (recA group III-B); and 5, B. stabilis strain LMG 14291. (B) Southern hybridization of separated chromosomes from panel A with a recA gene probe from B. cepacia strain K56-2 (genomovar III-A). A positive hybridization signal was obtained from the largest chromosome in each strain examined.
