Transposable elements (TE), small mobile genetic elements unable to exist independently
of the host genome, were initially believed to be exclusively deleterious genomic parasites …

Diversity in adaptive responses is common within species and populations, especially when
the heterogeneity of the frequently large populations found in environments is considered …

Abstract In 1964, Kundig, Ghosh and Roseman reported the discovery of the
phosphoenolpyruvate: sugar phosphotransferase system (PTS), which they subsequently …

Transposable Insertion Sequences (IS elements) have been shown to provide various
benefits to their hosts via gene activation or inactivation under stress conditions by …

Mutation rates may be influenced by the environment. Here, we demonstrate that insertion
sequence IS 5 in Escherichia coli inserts into the upstream region of the flhDC operon in a …

Bacteria can respond to adverse environments by increasing their genomic variability and
subsequently facilitating adaptive evolution. To demonstrate this, the contribution of Insertion …

Insertion sequence elements (ISE) are often found to be responsible for the collapse of
production in synthetically engineered Escherichia coli. By the transposition of ISE into the …

Transposons, mobile genetic elements that can hop from one chromosomal location to
another, are known to be both beneficial and deleterious to the cell that bears them. Their …

Insertion sequence elements (IS elements) are proposed to play major roles in shaping the
genetic and phenotypic landscapes of prokaryotic cells. Recent evidence has raised the …

Wildtype Escherichia coli cells cannot grow on L-1, 2-propanediol, as the fucAO operon
within the fucose (fuc) regulon is thought to be silent in the absence of L-fucose. Little …
