Scientists at the University of California San Diego have discovered new plant enzymes that can allow plants to save water while consuming more CO2 from the atmosphere. The enzyme causes the plants to react to CO2 and change how they use their pores and by modifying the enzyme, scientists believe that could be developed more CO2- and drought-tolerant crops.
