Large-scale toxicogenomic screening approaches offer great promise for generating a bias-free system-wide view of toxicological effects and modes-of-action of chemicals and ecotoxicants. However, early applications of microarray technology have identified relatively small groups of responding genes with which to define
An efficient 3,4-dichloroaniline (3,4-DCA)-mineralizing bacterium has been isolated from enrichment cultures originating from a soil sample with a history of repeated exposure to diuron, a major metabolite of which is 3,4-DCA. This bacterium, Bacillus megaterium IMT21, also mineralized 2,3-, 2,4-
Arylhydrocarbon receptor (Ahr) and cytochrome P4501a1 (Cyp1a1) are members of the Ahr/Cyp1a1 pathway that oxygenates various toxic chemicals including aryl hydrocarbons. To elucidate Ahr/Cyp1a1 pathway responses in teleost fish tissues, we examined the effects of 3,4-dichloroaniline (3,4-DCA), a reference toxic
Individual-based models (IBMs) predict how dynamics at higher levels of biological organization emerge from individual-level processes. This makes them a particularly useful tool for ecotoxicology, where the effects of toxicants are measured at the individual level but protection goals are

A proteomic approach was used to explore the metabolism of the phenylurea herbicide linuron and 3,4-dichloroaniline (3,4-DCA) in Variovorax sp. WDL1. This bacterium grows on linuron as sole source of carbon, nitrogen and energy, while it transiently accumulates 3,4-DCA as
