TL;DR
Nucleotide sequences of translated regions of the trp operon in 12 wild strains of Escherichia coli reveal striking uniformity among eight strains and clustered substitutions in four strains, suggesting recent common ancestry and supporting the importance of periodic selection in natural populations.
Abstract
Nucleotide sequences of translated regions of the trp operon in 12 wild strains of Escherichia coli reveal striking uniformity among eight strains (suggesting recent common ancestry and supporting the importance of periodic selection in natural populations) and clustered substitutions in four strains (implicating events affecting runs of nucleotides).

The gene for the so-called M(r) 32,000 rapidly labeled photosystem II thylakoid membrane protein (here designated psbA) of spinach (Spinacia oleracea) chloroplasts is located on the chloroplast DNA in the large single-copy region immediately adjacent to one of the inverted repeat sequences.

A survey of allozyme variation at 12 enzyme loci in 1,705 clones of the genetic species Escherichia coli revealed 302 unique allele combinations (electrophoretic types), which reflect genetic differentiation of E. coli into three groups of strains.

It is postulated that E. coli is composed of a relatively limited number of geographically widespread and genetically nearly isolated and monomorphic lineages, and the implications of these considerations of the genetic structure of E. bacteria populations on the interpretation of protein variation and the neutral gene hypothesis are discussed.
ScienceElectrophoretic Variation in <i>Escherichia coli</i> from Natural Sources
190 Citations1973Roger Milkman
Electrophoretic analysis of Escherichia coli clones reveals a prominent mobility class (frequency over 0.70) and 2 to 11 distinct mobility classes at lower frequencies, which argues against the importance of neutral mutations in allozymic variation.

The amino acid sequence deduced for the E. coli gene product is in agreement with earlier, fragmentary protein sequence results, and the trpB nucleotide sequences for the two bacterial species are perfectly colinear and show 85% identity.

The conclusion is that it is likely that evolution at a locus proceeds in the course of many population replacements or revolutions, mostly via the rare occasions when the revolution carries a previously infrequent mutational type into abundance.

The DNA sequence for the portion of the Escherichia coli tryptophan (trp) operon spanning trpC, which codes for the bifunctional enzyme N-(5′-phosphoribosyl)-anthranilic acid isomerase/indole-3-glycerol phosphate synthetase, is determined.

Comparisons with Escherichia coli reveal that segments thought to play important roles in transcription regulation by attenuation are highly conserved, and suggests that many of the synonymous codon changes that have occurred in these genes have no selective value.

The results support the conclusions that genetic exchange among B. subtilis 168 strains in soil is general, that it occurs in an ecologically reasonable setting, and that observed gene frequency changes can be driven by selection.
