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 ...

Hydrogen and carbon isotope ratios of cellulose nitrate and oxygen isotope ratios of cellulose from C3, C4, and Crassulacean acid metabolism (CAM) plants were determined for plants growing within a ...

C4 photosynthesis represents a striking example of convergent evolution, where multiple plant lineages have independently modified an ancestral C3 pathway to enhance carbon fixation efficiency. This ...

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 ...

Two species of Atriplex were grown under low temperature (8 C day/6 C night) and high temperature (28 C day/20 C night) regimes. The photosynthetic capacity of these plants was studied as a function ...

An international long-term research collaboration aimed at creating high yielding and water use efficient rice varieties, has successfully installed part of the photosynthetic machinery from maize ...

The RuBisCO enzyme, the most abundant protein on the planet, is an essential component of photosynthesis, but it isn’t terribly efficient, especially when it gets hot. Over time, some plants evolved a ...

Generally when we consider the many plants around us, we imagine them efficiently using the electromagnetic radiation from the Sun via photosynthesis in their leaves — pulling carbon-dioxide from the ...
