2,4-Dichlorophenoxyacetic Acid Inhibits the Outer Membrane NADH Dehydrogenase of Plant Mitochondria

Abstract
The NADH dehydrogenase of potato (Solanum tuberosum) and mung bean (Phaseolus aureus) outer mitochondrial membranes is specifically inhibited by both 2,4-dichlorophenoxyacetic and 2,4,5-trichlorophenoxyacetic acids but not by the natural auxin indole-3-acetic acid.
