Subcellular Metabolite Levels in Spinach Leaves : Regulation of Sucrose Synthesis during Diurnal Alterations in Photosynthetic Partitioning.
نویسندگان
چکیده
The alterations of subcellular metabolite levels during the day in spinach leaves have been investigated using nonaqueous density gradient centrifugation to separate chloroplasts, cytosol, and vacuole. The results provide direct evidence for the role of sucrose phosphate synthase and cytosolic fructose 1,6-bisphosphatase in regulating sucrose synthesis in leaves and also show that the phosphate translocator is kinetically limiting in vivo.

Transgenic Arabidopsis plants with decreased activity of fructose-6-phosphate,2-kinase/fructose-2,6-bisphosphatase have altered carbon partitioning.
The role of fructose-2,6-bisphosphate (Fru-2,6-P(2)) as a regulatory metabolite in photosynthetic carbohydrate metabolism was studied in transgenic Arabidopsis plants with reduced activity of Fru-6-phosphate,2-kinase/Fru-2,6-bisphosphatase. A positive correlation was observed between the Fru-6-phosphate,2-kinase activity and the level of Fru-2,6-P(2) in the leaves. The partitioning of carbon wa...
متن کاملEvidence for control of carbon partitioning by fructose 2,6-bisphosphate in spinach leaves.
Excision of spinach (Spinacia oleracea L.) leaves had no effect on photosynthetic rates, but altered normal carbon partitioning to favor increased formation of starch and decreased formation of sucrose. The changes were evident within 2 hours after excision. Concurrently, leaf fructose-2,6-bisphosphate content increased about 5-fold (from 0.1 to 0.5 nanomoles per gram fresh weight). The activit...
متن کاملA Role for Fructose 2,6-Bisphosphate in the Regulation of Sucrose Synthesis in Spinach
The subceliular distribution of fructose 2,6-bisphosphate in spinach (Spinacia oleracea) leaves was studied using nonaqueous fractionation, showing that all, or almost all, is located in the cytosol. The amount of fructose 2,6-bisphosphate present in leaves during the diurnal cycle was measured and compared to the accumulation of starch and sucrose, and the amounts of selected phosphorylated in...
متن کاملSucrose and Starch Synthesis in Spinach Plants Grown under Long and Short Photosynthetic Periods.
The flow of carbon into sucrose and starch was investigated in fully expanded primary leaves of spinach using the long to short day transition and partial defoliation as tools to manipulate sucrose/starch synthesis. Transfer from 12 hour to 7 hour photosynthetic periods resulted in a 4-fold increase in the initial rate of starch synthesis, a 50% increase in the initial rate of sucrose synthesis...
متن کاملThe diurnal metabolism of leaf starch.
Starch is a primary product of photosynthesis in leaves. In most plants, a large fraction of the carbon assimilated during the day is stored transiently in the chloroplast as starch for use during the subsequent night. Photosynthetic partitioning into starch is finely regulated, and the amount of carbohydrate stored is dependent on the environmental conditions, particularly day length. This reg...
