Distribution of chromosome length variation in natural isolates of Escherichia coli.

Molecular biology and evolution - 1 Jan 1998

Bergthorsson U, Ochman H

Abstract excerpt

Large-scale variation in chromosome size was analyzed in 35 natural isolates of Escherichia coli by physical mapping with a restriction enzyme whose sites are restricted to rDNA operons. Although the genetic maps and chromosome lengths of the laboratory strains E. coli K12 and Salmonella enterica sv. Typhimurium LT2 are highly congruent, chromosome lengths among natural strains of E. coli can differ by as much as...
