The influence of aflatoxins B1, B2, G1 and G2 obtained from Aspergillus flavus and A. parasiticus on the electron transport chain (from water to methyl viologen) of freshly lysed chloroplasts from maize and peas was investigated. A partially purified extract containing all 4 toxins was added to a chloroplast suspension. Basal, phosphorylating and uncoupled electron transport were assessed immediately after its addition and 4 min later.
