Influence of osmotic stress on the respiration of potato tuber callus

Linus H. W. van der Plas; Marijke J. Wagner Physiologia Plantarum 1984. doi:10.1111/j.1399-3054.1984.tb04592.x

Other claims from this paper (14)

Intervention effect Potato callus fresh weight decreased upon transfer to mannitol medium
Intervention effect Osmolarity of the intracellular fluid of potato callus increased upon transfer to mannitol medium
Mechanism Mannitol is probably taken up from the medium until tissue osmolarity equals that of the medium
Intervention effect Respiration of potato callus increased upon transfer to medium with extra mannitol, especially per fresh weight
Intervention effect On a fresh weight basis, cytochrome and alternative pathway capacities did not change appreciably with extra mannitol
Intervention effect Participation of the alternative pathway in uninhibited respiration of potato callus rose from about 10% to 90% upon transfer
Association Increase in respiration is partly correlated with decrease in fresh weight upon transfer
Intervention effect Capacities of the cytochrome and alternative pathway declined per disc upon transfer
Intervention effect Total respiration per disc of potato callus significantly increased upon transfer
Mechanism Total respiration per disc increased due to increased participation of the alternative pathway
Intervention effect ATP production per disc was almost unchanged before and after transfer
Mechanism The alternative pathway may function as a reserve capacity in potato callus when cytochrome pathway ATP production is impaired
Intervention effect Growth of potato callus became negligible on medium with 0.5 M mannitol after osmotic adaptation
Observation Potato callus retained its viability after osmotic adaptation on 0.5 M mannitol
