Evans, T.C. Vogelmann, and S. von Caemmerer Feeding Asia in the 21st century will require a second Green Revolution. However, unlike in the first generation, future yield increases will have to be grown using less water and nitrogen in a world of unfavorable climate change - this can only be done by increasing the efficiency of the photosynthetic system, i.e. developing a C4 rice plant. If and when achieved, it would be the first nonevolutionary example of reconstructing the primary metabolism of a plant. The impact of such a scientific achievement would be undeniable, but it requires either a superb feat of genetic engineering or forcRiceGenetic engineeringRiceYieldsCrop yieldsPhotosynthesisElectronic books.RiceGenetic engineering.RiceYields.Crop yields.Photosynthesis.633.182Sheehy J.
