Deep dives
Improving photosynthesis can alleviate food insufficiency
The podcast discusses how improving crop photosynthesis at the genetic level can help address the issue of food insufficiency. The speaker explains that the rising demand for food, especially in poorer countries, is outpacing our ability to supply it. While photosynthesis is a crucial process that plants use to convert carbon dioxide into food, our most productive crops are only achieving one-fifth of the potential efficiency of this process. The speaker introduces the concept of using a digital twin, a system that models photosynthesis using differential equations, to identify areas for genetic improvements. By making specific changes to genes and proteins involved in photosynthesis, the speaker and their team have already achieved over 20% increase in crop yields. These advancements in photosynthesis have the potential to alleviate food insufficiency and protect the environment.
