We followed adaptation in experimental microbial populations to
inhibitory concentrations of an antimicrobial drug. The evolution of
drug resistance was accompanied in all cases by changes in gene
expression that persisted in the absence of the drug; the new patterns
of gene expression were constitutive. The changes in gene expression
occurred in four replicate populations of the pathogenic fungus
Candida albicans during 330 generations of evolution in the presence
