Estimates of sucrose concentrations in source (leaf) and sink (root) sieve tubes were obtained by a negativestaining procedure.
      
Water potential measurements of the leaf and of the nutrient solution allowed calculation of the turgor pressures in source and sink sieve tubes.
      
In three experiments, the sucrose concentration was consistently higher in source sieve tubes (an average of 11.5%) than in sink sieve tubes (an average of 5.3%).
      
Biosynthesis of sucrosyl-oligosaccharides (raffinose, stachyose) was traced in source leaves of Cucumis melo after 14C-photoassimilation.
      
Control of photoassimilate movement in source-leaf tissues of Ipomoea tricolor Cav.
      
By contrast, in source-tuber discs, the linear component represented the majority of sucrose taken up, the saturable component playing only a minor role.
      
In source discs, only the saturable component of uptake was inhibited by either PCMBS or CCCP.
      
A large proportion (up to 25%) of sucrose taken up into sink-tuber discs was converted to starch but as the tubers aged the proportion of sucrose converted to starch decreased to the level found in source-tuber discs (approx.
      
These data show that, in Amaranthus edulis, depression in photosynthesis when translocation is impaired is closely related to the accumulation of soluble sugars (sucrose) in source leaves, indicating feedback control of C4 photosynthesis.
      
Rates of photosynthesis and partitioning between sucrose and starch in source leaves were identical in 4-40-91 transformants and the wild type.
      
We conclude that PFP does not play an essential role in photosynthate partitioning in source leaves.
      
Xanthi) plants expressing wild-type or mutant forms of the 30-kDa movement protein of tobacco mosaic virus (TMV-MP) were employed to study the effects of the TMV-MP on carbon metabolism in source leaves.
      
The relative importance of refixation of respiratory CO2 and variations in source isotope signature were considered to account for any variation between on-line and organic Δ.
      
In long-day-grown plants, NR activity in source leaves rose by 2- to 3-fold in the first part of the light period and decreased in the second part of the light period.
      
When wild-type plants were subjected to a single short day/long night cycle of increasing severity, NR activity in source leaves at the end of the night decreased when the endogenous sugars declined below about 3?μmol hexose (g FW)-1.
      
In sink leaves in short-day conditions, sugars were higher and the light-induced rise in NR activity was much larger than in source leaves on the same plants.
      
Biophysical limitation of leaf cell elongation in source-reduced barley
      
The biophysical basis of reduced leaf elongation rate in source-reduced barley (Hordeum vulgare L.
      
Reduction in source strength was achieved by removing the blade of leaves?1 and 2 at the time leaf?3 had emerged 3.0-6.7?cm from the encircling sheath.
      
Cell turgor was similar between treatments in the zone of maximal REGR (16-24?mm from base), but was significantly lower in source-reduced plants in the distal part of the elongation zone, where REGR was also lower.
