Abstract
SUMMARY The effect of the new herbicide, ioxynil, and several related compounds, on the oxidative phosphorylation of respiring, isolated pea shoot particles has been studied. Ioxynil and its analogues were found to depress the uptake of inorganic phosphate and, to a lesser extent, of oxygen by the particles; the calculated P/O ratio was eventually reduced to zero. The effect of ioxynil was far greater than that of the well-known uncoupling agent 2,4-dinitrophenol and was similar in magnitude to that of the contact herbicide dinitro-ortho-cresol.
