Additional Information
The RB7 gene matrix attachments region (MAR)  is a 1.2 kb fragment isolated from the 3' flanking region of the RB7 root-specific gene of tobacco.

When positioned on the flanking ends of gene cassettes, some the RB7 MAR has been shown to increase expression of transgenes and to reduce the incidence of gene silencing. It is hypothesized that MARs may act to buffer effects from neighbouring chromosomal sequences that could destabilize the expression of genes.
