Abstract
The effects of flavone on the oxidative and phosphorylative properties of plant mitochondria from potato tubers and etiolated mung bean hypocotyls were investigated. Flavone inhibited the state 3 oxidation rates of malate, NADH and, to a lesser extent, succinate but was without effect on the ascorbate-TMPD oxidation rate. The inhibition was the same whether the mitochondria were in state 3 or in an uncoupled state 3. When 100 μM flavone was added during the state 4, the tight coupling of succinate or NADH oxidation was not released. In the electron transfer chain, flavone inhibition appeared to be located in the flavoprotein region. All forms of NADH dehydrogenases seemed to be affected but the greatest inhibition appeared when exogenous NADH was used.
