This book discusses current genetic engineering methods for plants and addresses the commercial opportunities for transgenic plants. Topics covered include: Agrobacterium-mediated transformations; the use of electroporation; PEG-mediated transformation; microinjection; the microprojectile bombardment method; and the electrical discharge particle acceleration method. A concise account of the resistance of transgenic plants to insect attack, viral infection and herbicides has also been provided. Possibilities for genetic manipulation for proteins that have superior nutritional properties are discussed, and a brief account of tests confirming the safety and commercial validity of transgenic plants is included.
