FIG. 1.

Physical maps of E. coli genomic inserts conferring mitomycin resistance. “L” and “H” are plasmid names (e.g., L13 and H7), with “L” referring to pBR322-based plasmids and “H” referring to pUC18-based plasmids. (A) Region from min 9 in E. coli, where nine MMC-resistant clones were clustered (GenBank accession no. AE000186). (B) Region from min 44, where 18 MMC-resistant clones were clustered (GenBank accession no. AE000292). (C) Region from min 43, where 18 MMC-resistant clones were clustered (GenBank accession no. AE000284).
