Creating a Better Leaf

Could tinkering with photosynthesis prevent a global food crisis?

This story begins about two billion years ago, when the world, if not young, exactly, was a lot more impressionable. The planet spun faster, so the sun rose every twenty-one hours. The earliest continents were forming—Arctica, for instance, which persists as bits and pieces of Siberia. Most of the globe was given over to oceans, and the oceans teemed with microbes.

Could more efficient photosynthesis help feed the world?

When plant leaves absorb too much sunlight, a mechanism kicks in that releases the excess energy as heat, rather than photosynthesizing it. While it prevents leaf damage, sometimes it is too much of a good thing. That’s because once a cloud moves in or another leaf casts a shadow, there is a lag time before photosynthesis ramps up again. This lag time can rob crops of 20 percent of their full potential in terms of yield. Continue reading →
