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:
“I grow savager and savager every day, as if fed on raw meat, and my tameness is only the repose of untamableness. I dream of looking abroad summer and winter, with free gaze, from some mountain-side,... to be nature looking into nature with such easy sympathy as the blue-eyed grass in the meadow looks in the face of the sky. From some such recess I would put forth sublime thoughts daily, as the plant puts forth leaves.”
—Henry David Thoreau (1817–1862)
