Abstract
The mechanisms of inhibition of the alternative pathway of plant mitochondria by salicylhydroxamic acid (SHAM), propylgallate (PG), 8-OH quinoline or disulfiram are still a subject of controversy. It has been suggested that these inhibitors could bind to a specific protein (Siedow, 1982) or could act as free radical scavengers (Rustin et al.,1984). In this work, it is shown that these inhibitors also display redox properties and could act as electron donors to the respiratory and photosynthetic chains.
