Throughout the elongation zone, osmolality and growth-associated water potential gradients were significantly smaller in source-reduced plants; bulk concentrations of sugars (hexoses, sucrose) were also lower.
      
The most likely biophysical limitation to leaf (cell) elongation in source-reduced barley was a reduction in turgor in the distal half of the elongation zone.
      
Observations in source leaves indicated that sieve element-companion cell complexes of minor veins were symplasmically restricted, suggesting a role of TaSUT1 in apoplasmic phloem loading.
      
As a result, CO2 assimilation in source leaves was sustained at both ambient CO2 and saturating CO2.
      
In contrast, all of the genes for OsTPT, OsPPT, and OsNTT were mainly expressed in source tissues, suggesting that their proteins play essential roles in the regulation of carbohydrate metabolism in chloroplasts.
      
Utilization of covariation knowledge in source monitoring: no evidence for implicit processes
      
The source monitoring framework (Johnson, Hashtroudi, and Lindsay, in Psychological Bulletin, 114, 3-28, 1993) postulates heuristic and strategic judgment processes in source attributions.
      
Expression was stronger in sink leaves than in source leaves, indicating developmental regulation.
      
We suggest that tree growth and the defensive response of phloem tissues may be limited more by the rate of carbohydrate utilization or by changes in source-sink relationships than by storage levels.
      
We hypothesized that these differences in source/sink ratio between the sexes and within females, depending on pollination, would lead to differences in leaf photosynthetic rates.
      
Partitioning of 14C-labeled photosynthate to allelochemicals and primary metabolites in source and sink leaves of aspen: evidenc
      
Within 48?h of labeling, the specific radioactivity (dpm/mg dry leaf weight) of phenolic glycosides declined by over one-third in source and sink leaves.
      
In addition, the specific radioactivity in the tannin/phenolic fraction decreased by 53% and 28% in source and sink leaves, respectively.
      
Analyses of the phenolic fractions showed that total phenolics were twice as great and condensed tannins were 1.7 times greater in sink than in source leaves.
      
The concentration of total phenolics and condensed tannins did not change in source and sink leaves during the 7-day chase period.
      
The isotopic composition of tree ring cellulose was obtained over a 2-year period from small-diameter riparian-zone trees at field sites that differed in source water isotopic composition and humidity.
      
Uncertainty in source partitioning using stable isotopes
      
Uncertainty in source partitioning using stable isotopes
      
The suite of observations suggests three distinct tremor regimes that may correspond to slug flow, bubbly flow, and sustained strong eruptions, or a cyclic change in source parameters (e.g., geometry, sound speed, or ascent rate).
      
This geochemical change in source characteristics might reflect the onset of a change in geotectonic regime, from crustal subduction to spreading, affecting the D'Entrecasteaux Islands region.
