Source metabolism dominates the control of source to sink carbon flux in tuberizing potato plants throughout the diurnal cycle and under a range of environmental conditions

Abstract:

The aim of this work was to investigate the effect of environmental conditions on the control of source to sink carbon flux in potato during tuberization. Top down metabolic control analysis was used to quantitatively determine the extent to which source and sink reactions control the flux from CO2 to the tuber. Under all conditions investigated (beginning of the dark period, low nitrogen availability, variation in temperature) source metabolism accounts for at least 80% of the control. In pl...
