Toward the Genetic Engineering of Disease Resistance in Plants: The Transfer of Pea Genes to Potatoes
The heightening concern of consumers about the pesticide residues of food has resulted in the loss of or requirement for reregistration of some of the mainstay pesticides used in agriculture (Richardson 1989). As this process continues, the need for employing any and all natural processes that can contribute to plant protection becomes paramount. The abundance and low cost of foods to date has contributed to the low level of funding for plant research. The plant scientist is now facing an urgent demand for natural plant protection without an extensive backlog of supportive basic research. That is, we are expected to replace the rare, effective chemicals derived from millions of synthetically generated compounds with natural compounds (Bell 1981; Bailey and Mansfield 1982) that are painstakingly derived from natural defense responses in plants. Further, these compounds must also be effective when applied externally, be scrutinized for safety concerns, be reasonable in price, and be applicable to the existing agricultural practices.
