Loss of expression of cspC, a cold shock family gene, confers a gain of fitness in Escherichia coli K-12 strains.

Abstract excerpt

The CspA family of cold shock genes in Escherichia coli K-12 includes nine paralogs, cspA to cspI. Some of them have been implicated in cold stress adaptation. Screening for mutations among common laboratory E. coli strains showed a high degree of genetic diversity in cspC but not in cspA and cspE. This diversity in cspC was due to a wide spectrum of variations including insertions of IS elements, deletion, and...
