Restoration of Organic Acid Accumulation in Sectioned Leaves of Bryophyllum tubiflorum Harv

When leaves of Bryophyllum tubiflorum were cut into transverse sections, and held at 20 C in the dark, the capacity to accumulate organic acid decreased with decreasing section thickness. In addition, the rate of respiration increased with decreasing section thickness and was unaffected by changes in O(2) concentration above 5% or by the presence (1%) of CO(2). It was concluded that O(2) ventilation is not a controlling factor in respiration. Malonate (0.1 m) and fluoroacetate (0.01 m) restored the capacity of sectioned leaves to accumulate acid to normal levels and depressed respiration in 1-millimeter sections. Acid accumulation in 8-millimeter sections remained essentially constant at 20, 15, and 10 C, and was equal to that in unsectioned leaves, but accumulation in 2-millimeter sections rose to normal levels as the temperature fell to 10 C. Twenty-three additional metabolic inhibitors (none specific to the tricarboxylic acid cycle) were screened, and none promoted acid accumulation in sectioned leaves at 20 C. The results suggest that sectioning stimulates a respiratory sequence which includes the tricarboxylic acid cycle. This sequence in turn competes with the synthesis or accumulation of malic acid.     

Wounding Stimulates Cyanide-sensitive Respiration in the Highly Cyanide-resistant Leaves of Bryophyllum tubiflorum Harv

The rate of respiration in sectioned leaves of Bryophyllum tubiflorum Harv. increases with decreasing section thickness. The rates of uninhibited respiration in 2- and 8-millimeter-thick sections are 74 and 46 microliters of O₂ per gram fresh weight of unruptured tissue per hour at 20 C, whereas the rate in the presence of cyanide is 31 microliters of O₂ in each case. The rates are unaffected by salicylhydroxamic acid, but cyanide and salicylhydroxamic acid together completely eliminate O₂ uptake. The capacity of the alternative respiratory pathway is thus initially high (estimated at 84% of the uninhibited respiratory rate in whole leaves) and remains constant but probably unexpressed subsequent to the rapid induction of wound respiration.
