When apical bud sections of Phaseolus vulgaris were vacuum-infiltrated with malformin, their rate of respiration increased significantly without a lag and without altering the respiratory quotient. When tissues were soaked in solutions, the effect of malformin was concentration dependent. At high malformin concentration (200 μM), a marked inhibition of respiration for 8 to 10 hr was followed by a rapid increase of oxygen uptake which reached a level nearly 3-fold greater than that of controls. At lower concentration (20 μM) malformin had no effect on respiration for 8 to 10 hr, but then stimulated respiration markedly. Ca^<2+> completely blocked the early inhibition of respiration by malformin (200 μμM), but had little or no effect on the subsequent stimulation of respiration. Oxygen deficiency may be a contributing factor to the enhancement of ethane production by malformin.
