Determining the molecular changes that give rise to functional innovations is a major
unresolved problem in biology. The paucity of examples has served as a significant …

Pseudomonas putida is a fast-growing bacterium found mostly in temperate soil and water
habitats. The metabolic versatility of P. putida makes this organism attractive for …

Comamonas testosteroni TAU1 was not able to grow on phenol as a sole carbon and
energy source, but it gained the ability to utilize phenol after a 2-3-week incubation in a …

6% of the genome of the soil bacterium P seudomonas putida KT 2440 encodes phage‐
related functions, but the burden of such opportunistic DNA on the host physiology is …

Transpositional activity of mobile elements can be induced by different environmental
stresses. Here, we present evidence that transposition of Tn 4652 is elevated in stationary …

LITTLE excuse is needed for still being interested environment) or simply to optimize the
return from investing in protective mechanisms (a matter of costs in mutation. We are here …

Major advances in understanding the molecular mechanism of recombination-dependent
stationary-phase mutation in Escherichia coli occurred this past year. These advances are …

The concept of evolvability covers a broad spectrum of, often contradictory, ideas. At one
end of the spectrum it is equivalent to the statement that evolution is possible, at the other …

Thermostable direct haemolysin of Vibrio parahaemolyticus has been shown to be a major
virulence factor. The Kanagawa phenomenon (KP), haemolysis induced by this haemolysin …

Microorganisms are exposed to constantly changing environmental conditions. In a growth‐
restricting environment (eg during starvation), mutants arise that are able to take over the …
