Abstract
The cyanide-resistant, alternative pathway respiration in slices and isolated mitochondria of Solanum tuberosum L.was analyzed during aging. During the aging process,the total respiration rate (Vt) and the capacity of alternative pathway (Valt) in slices incrased by 5-fold and 28-fold, respectively,but the alternative pathway was almost not operative in the absence of KCN. Application of 20 μmol/L of salicylic acid to aging slices slightly increased the total respiration rate and the capacity of alternative pathway, however,the operation of the SHAM-sensitive alternative pathway was greatly enhanced by application of salicylic acid during the aging process of potato slices. This enhancing effect of salicylic acid was also observed in Percoll-purified mitochondria. The elevated operation of the alternative pathway, which is known as the nonphosphorylating electron transport system, led to a decline of the RCR ratio as well as of the ADP/O value in mitochondria.These daal indicate that salicylic acid induces the activity of alternative pathway during aging of potato tuber slices.
