The rice squad
Global production of rice, the world’s most important staple crop, has risen threefold over the past three decades. But yields are fast approaching a theoretical limit set by the crop’s efficiency in harvesting sunlight and using its energy to make carbohydrates.
So to feed the world, rice may have to be re-engineered at the biochemical level. Scientists are currently working to manipulate rice genes to boost the plant’s photosynthetic efficiency.
