Changes in intracellular redox and energy status during induced transplasma membrane electron transport in Cuscuta

Abstract:
Extracellular reduction of ferricyanide was exhibited by isolated Cuscuta protoplasts. A larger decrease in NADH than NADPH levels of the ferricyanide-treated protoplasts pointed to the major involvement of the former as an electron donor. Glutathione levels were also found to be lowered in similarly treated tissue. The time-dependent variation in intracellular ATP levels in presence of ferricyanide supported the concept of plasma membrane ATPase activation during transplasma membrane electron transport in eukaryotes.
