Metabolic Adaptations of Plant Respiration to Nutritional Phosphate Deprivation.

Author information

Plants respond adaptively to orthophosphate (Pi) deprivation through the induction of alternative pathways of glycolysis and mitochondrial electron transport. These respiratory bypasses allow respiration to proceed in Pi-deficient plant cells because they negate the necessity for adenylates and Pi, both pools of which are severely depressed following nutritional Pi starvation.
