Selectable marker genes (SMGs) are still useful to efficiently obtain transgenic plants, although marker-free techniques are available, but with limitations. The presence of SMGs, especially bacterial ...

Journal of Experimental Botany, Vol. 60, No. 11 (2009), pp. 3195-3202 (8 pages) Genetic engineering of chloroplasts normally requires the stable introduction of bacterial derived antibiotic or ...

When introducing foreign genes into plants, scientists must also introduce a resistance gene to herbicide or antibiotics–this allows the cells with the incorporated transgenes to be regenerated on ...

Low transfection efficiencies can obscure the results of even the most carefully planned experiment. Selection systems for enrichment of successfully transfected cells can help, but in the past ...
