The chief distinction between these two pathways is the presence of specialized, thick-walled photosynthetic cells located in sheaths surrounding vascular bundles in C-4 plants.
In the range of temperatures studied, an isopropanol to propylene mole fraction ratio close to 0.25 suggests a branching ratio of 1.5 between these two pathways in favor of propylene production.
But the reason why there are two pathways (K and D pathways) responsible for oxygen reduction is not clear, and the functional difference between these two pathways is not know either (Fig. 1).
Cross-talk between these two pathways and the UPR indicates that the ER stress system may play an indirect role through interaction with death ligand-receptor and mitochondria-mediated molecular signaling pathways in the regulation of GC apoptosis.
These examples indicate a close interaction between these two pathways.
The alternation in carbon flow between these two pathways raises another issue.
Gata3 may thus regulate cell survival by priming the balance between these two pathways.
The differentiation of specific structures results from the balance between these two pathways.
How does the cell direct carbon in the required direction and mediate the oscillation between these two pathways?
Both Wnt and BMP pathways were initially selected after the findings of Nishanian et al. [34], who demonstrated the interaction between these two pathways.
Perhaps the downregulation of PKA in the liver has shifted the balance between these two pathways, favoring insulin-like tone and improving the clearance of glucose from the blood stream.
