Transgene containment by maternal inheritance: effective or elusive?
T ransgene containment is a central concern in genetically modified (GM) crops, especially for those with out-crossing wild relatives. However, plant cells contain genomes in the nucleus, mitochondria, and chloroplasts. Whereas nuclear genes are biparentally inherited, organelle genes are in general maternally inherited (1, 2). Therefore, engineering foreign genes in the chloroplast genome may ...
متن کاملTransgene containment by molecular means--is it possible and cost effective?
With the rapid advancement of transgenic biotechnology, large numbers of transgenic crops have been produced and released for commercial cultivation (James, 2001), raising considerable biosafety concerns all over the world. One of the major issues is the potential ecological risk resulting from transgenes escaping into and persisting in the environment. The extensive on-going debate on this iss...
متن کاملTransgene inheritance in plants.
The patterns of transgene inheritance in plants and the possible explanations for non-Mendelian transmission are reviewed. The non-Mendelian inheritance of a transgene has been recorded with a frequency between 10% and 50% in transgenic plants produced either by Agrobacterium-mediated transformation or through particle bombardment. Different effects such as deletion, duplication, rearrangement,...
متن کاملDetermining the transgene containment level provided by chloroplast transformation.
Plastids (chloroplasts) are maternally inherited in most crops. Maternal inheritance excludes plastid genes and transgenes from pollen transmission. Therefore, plastid transformation is considered a superb tool for ensuring transgene containment and improving the biosafety of transgenic plants. Here, we have assessed the strictness of maternal inheritance and the extent to which plastid transfo...
