Epigenetic variants of a transgenic petunia line show hypermethylation in transgene DNA: an indication for specific recognition of foreign DNA in transgenic plants.

Molecular & general genetics : MGG - 25 May 1994

Meyer P, Heidmann I

Abstract excerpt

We analysed de novo DNA methylation occurring in plants obtained from the transgenic petunia line R101-17. This line contains one copy of the maize A1 gene that leads to the production of brick-red pelargonidin pigment in the flowers. Due to its integration into an unmethylated genomic region the A1 transgene is hypomethylated and transcriptionally active. Several epigenetic variants of line 17 were selected that...
