Abstract (en)

[origin: WO9855608A1] A method of reducing gene silencing, increasing expression, and/or reducing expression variability of foreign DNA in plants or plant cells comprises providing a plant cell capable of regeneration; and then transforming said plant cell with a DNA construct comprising an expression cassette, which construct comprises, in the 5' to 3' direction, a first matrix attachment region, a transcription initiation region, a structural gene positioned downstream from said transcription initiation region and operatively associated therewith, and a second matrix attachment region, wherein said first and second matrix attachment regions are different.
