The highly toxic and carcinogenic substance Aflatoxin, is produced by a widely spread saprophytic fungus Aspergillus flavus. Aflatoxin greatly reduces the export value of groundnut. In drought-prone regions, the infection is encouraged by terminal drought stress. Breeding programmes, up to now, have failed to create a groundnut cultivar resistant to aflatoxin and of high agronomic importance. The main objective of this project is to identify physiological, biochemical and molecular resistance mechanisms of the host plant in order to improve selection and to develop an integrated system for the prevention and control of aflatoxin contamination in the field. Progress made in widening knowledge on these mechanisms and in particular their relationship with plant water supply will contribute to the development of improved resistant or tolerant varieties, and cultural and post-cultural practices limiting aflatoxin occurrence.
