Plants reap energy from the sun using two photosynthesis pathways, C3 and C4. A new study suggests that water availability drove the expansion of C4 species, which may help to explain how different ...
The C4-photosynthetic carbon cycle is an elaborated addition to the classical C3-photosynthetic pathway, which improves solar conversion efficiency. The key enzyme in this pathway, phosphoenolpyruvate ...
Dysregulated complement pathways are linked to progression from iAMD to advanced AMD, including NVAMD and GA. Higher systemic levels of C4, C4b, and a reduction in C3 are associated with increased ...
