Abstract excerpt

We investigate a model system for microevolution of transcriptional regulation: metallothionein expression in springtails. A previous survey of the metallothionein promoter in Orchesella cincta (Collembola) revealed nine alleles with differential basal activities and responses to cadmium and oxidative stress. In this study, 23 woodlands, with a divergent degree of pollution, were sampled, and heavy metals were...
