Integrative and conjugative elements (ICEs) are a diverse group of mobile genetic elements
found in both Gram-positive and Gram-negative bacteria. These elements primarily reside in …

Conjugative transfer of bacterial plasmids is the most efficient way of horizontal gene
spread, and it is therefore considered one of the major reasons for the increase in the …

Haydon and Guest (Haydon, D. J, and Guest, JR (1991) FEMS Microbiol. Lett. 63, 291–295)
first described the helix-turn-helix GntR family of bacterial regulators. They presented them …

Abstract The 8–9-Mb Streptomyces chromosome is linear, with a “core” containing essential
genes and “arms” carrying conditionally adaptive genes that can sustain large deletions in …

An Escherichia coli–actinomycete shuttle vector, pCJW93, was constructed which places
cloned genes under the control of the thiostrepton-inducible tip promoter from Streptomyces …

A mutation in a newly discovered Escherichia coli cell division gene, ftsK, causes a
temperature-sensitive late-stage block in division but does not affect chromosome …

Plasmids and bacteriophage represent the classical vectors for gene transfer within the
horizontal gene pool. However, the more recent discovery of an increasing array of other …

Deletion of ftsK results in the inhibition of cell division, but this inhibition can be reversed by
a plasmid carrying only the first∼ 17% of ftsK. The division block can be suppressed in most …

Spore formation in Bacillus subtilis begins with an asymmetric cell division that superficially
resembles the division of vegetative cells. Mutations in the spoIIIE gene of B. subtilis partially …

DNA transport is important in various biological contexts—particularly chromosome
segregation and intercellular gene transfer. Recently, progress has been made in …
