Genetic analysis of the chromosome of alkaliphilic Bacillus halodurans C-125 and comparison with the genetic map of B. subtilis. Each gene from alkaliphilic B. halodurans C-125 was mapped on the linkage map of Sse8387I fragments (S). The scale of 360^｡, beginning with zero at the dnaA locus, is based on the B. subtilis map (Anagnostopoulos et al. 1993, Biaudet et al. 1996, and Kunst et al. 1997). The genetic symbols used in this figure are defined in Table 1 and previous reports (Takami et al. 1999b, 1999c and 1999d). The dashed line and regular line represent the B. subtilis chromosome and the B. halodurans C-125 chromosome, respectively.
