In mammals, some fungi, and plants, DNA methylation plays a central role in the epigenetic control of gene transcription. Recently, however, a subclass of Arabidopsis mutants revealed that the release of transcriptional gene silencing (TGS) does not

Transcriptional gene silencing (TGS) frequently inactivates foreign genes integrated into plant genomes but very likely also suppresses an unknown subset of chromosomal information. Accordingly, RNA analysis of mutants impaired in silencing should un

Summary Cells have developed a complex network of reactions to avoid or reduce the deleterious consequences of DNA damage. Responses to genotoxic stress include activation of distinct stress signaling pathways, delay of cell cycle progression and ind

Gene silencing in plants inactivates transgenes introduced into plants and/or endogenous homologous genes. This stable but potentially reversible loss of gene activity resembles epigenetic changes that occur in normal development. The stability of si

Polyploidization is found frequently in plants, and species previously considered to be diploid may show remnants of earlier polyploidization events on closer inspection of their genomes. The success of polyploids may lie in increased genetic redunda

Epigenetic modifications change transcription patterns in multicellular organisms to achieve tissue-specific gene expression and inactivate alien DNA such as transposons or transgenes. In plants and animals, DNA methylation is involved in heritabilit

A recessive Arabidopsis mutant with elevated sensitivity to DNA damaging treatments was identified in one out of 800 families generated by T-DNA insertion mutagenesis. The T-DNA generated a chromosomal deletion of 1287 bp in the promoter of one of th

Epigenetic silencing of gene expression is often correlated with extensive DNA methylation at cytosine residues in the promoter and the coding region of silenced genes. Increasing evidence indicates that, in such cases, DNA methylation can also occur

A silent transgene in Arabidopsis thaliana was reactivated in an outcross but not upon selfing of hemizygous plants. This result could only be explained by assuming a genetic difference between the transgene-free gametes of the wild-type and hemizygo
