Research into agricultural productivity, especially for crops in the developing world, should include resistance to plant viruses, fungi and the parasitic weed Striga. It must also include research into the development of resistance to Bacillus thuringiensis (Bt) toxin-expressing crops. Drought- and heat-tolerant crops, and those that can combat the problems of soil deficiencies, are required, and vaccine production in plants should be a high priority. Research into food quality should include the equivalent of "golden rice" in maize, the enhancement of the production of phytosterols and improved qualities of vegetable oils.

KEY WORDS: • biotic stress • abiotic stress • biotechnology
