Additive genetic variation of transcriptional regulation: Metallothionein expression in the soil insect Orchesella cincta

Article Abstract:

Midparent offspring regression analysis of metallothionein (mt) gene expression in a laboratory culture originating from a noncontaminated natural population of Orchesella cincta is described. The results suggest that evolution of metal tolerance in O. cinta can occur in the field by selection for high mt expression due to structural changes in mt cis-regulation.

Transcription of the 5S rRNA heterochromatic genes is epigenetically controlled in Arabidopsis thaliana and Xenopus laevis

Article Abstract:

An analysis of the 5S ribosomal DNA, the highly conserved recurring multigenic species, is done to exhibit that 5S rDNA is highly regulated at various levels and that epigenetic mechanisms like changes of the chromatin structure, are involved in organisms, Arabidopsis thaliana and Xenopus laevis.
