The increasing burden of global food and bioenergy demand on shrinking agricultural lands requires attention. Famines and energy shortfall is inevitable due to the population growth. Bioeconomy also requires more lands and agricultural productivity.
Different plants absorb and metabolize the carbon during photosynthesis via different mechanisms.
Botanists classify plants into three groups: C3, C4 and CAM Plants. All these plants perform the same basic mechanism of converting atmospheric Carbon Dioxide into the sugars. The mechanism involved includes variation in the Calvin Cycle.
