Fig 1. Relationship of ER2796 and ER3413 to the nine other completely sequenced E. coli K-12 strains.

Fig 1

Completely sequenced strains are shown in bold type, and selected ancestral strains in Roman type. Most of the tree has been abstracted from Bachmann [28], except for the ancestries of MC4100 and DH10B back to Hfr Hayes, which are based on Laehnemann [63] and Durfee [4], respectively. Selected additional contributions of genetic material via crosses are shown by dotted lines. It appears based on genotype that Hfr 3000 U482 is the “U series” ancestor of DH10B, while Hfr 3000 U169 contributed genetic material in the ancestry of MC4100.
