Comparative effects of the toxin produced by Helminthosporium maydis race T on mitochondria isolated from maize with male sterile Texas cytoplasm and with normal cytoplasm



Comparative effects of the toxin produced by Helminthosporium maydis race T on mitochondria isolated from maize with male sterile Texas cytoplasm and with normal cytoplasm



Comptes Rendus Hebdomadaires des Seances de l' Academie des Sciences, D 278(7): 885-888



The toxin from H. maydis (Cochliobolus heterostrophus) stimulated oxidation of NADH in mitochondria of Texas male sterile cytoplasm (T). When this pathway was blocked by rotenone, the stimulating effect disappeared and the T mitochondria behaved as those in normal cytoplasm, suggesting that the site of action of the toxin lies on the oxidation pathway sensitive to rotenone.
