The success of the dwarf breeding rice and wheat, called Green Revolution, was due to increased source sink capacities, which depended on large increases in N fertilizer inputs. However, today’s high fertilization has an extremely impact environment. While there have been disputes as whether photosynthetic improvement leads increase crop yields, transgenic overproducing ribulose-1,5-bisphosphat...
