Chimeras in Plant Transformation
Genetic engineering is widely used to alter the traits of certain plants. Generally speaking, it involves recombinant DNA integration, either through traditional or non-traditional way, and transgenic plant recovery. Agrobacterium mediated transformation involves callus generation, co-cultivation with agrobacterium and later on followed by plant regeneration. Tissued transformed with exogenous genes could contain both transformed cells and non-transformed cells. In many plant transformation systems, a selection marker such as the herbicide or antibiotics resistance genes is utilized to distinguish the transformed ones with untransformed ones. Even so there is still high chance that transgenic plant became a chimera.

Famous quotes containing the word plant:
“The student of Nature wonders the more and is astonished the less, the more conversant he becomes with her operations; but of all the perennial miracles she offers to his inspection, perhaps the most worthy of admiration is the development of a plant or of an animal from its embryo.”
—Thomas Henry Huxley (1825–95)
