Trangene Inheritance in Transgenic Wheat
Abstract: The achievement in
genetic transformation is not only determined by the success in integrating transgenes
into the plant genome, but also by the ability of transgenes to be stably
expressed in the following generations.
Transgenes integrated into trangenic wheat obtained via microprojectile
bombardment method could be transmitted
and, in most cases, expressed until the third generation as demonstrated in
this study. The expression of the GUS
gene was stable as observed in leaves, microspores,
anthers, ovaries and seeds. Nevertheless, the bar gene
appeared to undergo a reduction
or disappearance in expression in a number of plants from the first to the
third generation.
