| Sumario: | The yields of major crops, such as rice, have reached a plateau and are unlikely to meet the global demand for food, mostly in developing countries. Increasing rice photosynthesis has been identified as an approach to enhance rice yield. . In the present study, I used two different strategies to create a population of transgenic plants expressing different combination of genes aiming to increase the capacity of rice to fix carbon dioxide during photosynthesis and thus produce rice with enhanced biomass, which is an important trait related to grain yield. I created a population of transgenic rice plants expressing the glycolate catabolic pathway to investigate if this pathway might be able to increase the biomass of rice. In a series of alternative experiments I introduced a carbon concentrating mechanism (CCM) into rice. I conclude that the introduction of the glycolate catabolic bypass pathway or carbonic anhydrases into rice might be a useful approach to increase the yield of rice plants. |
