genetically modified plants

Quick Reference

Two methods are used to transfer foreign DNA into plant cells: i) the gene can be incorporated into the genome of a pathogenic bacterium (Agrobacterium spp.); ii) direct gene transfer methods either by hydrolysing the cellulose cell wall enzymically, followed by stimulation of DNA uptake into the resulting protoplasts by use of polyethylene glycol or electric pulses, or by shooting DNA-coated particles of heavy metal into tissues (the technique of particle bombardment or biolistic transformation).

Subjects: Medicine and Health.
