Inside the scientific drive to future-proof corn
Corn, wheat, barley, and other plants suffered from too much heat and too little water during the summer's worldwide drought.
As climate change makes the planet hotter and drier, this scenario will become increasingly typical.
Scientists are using pineapples, orchids, and agaves to help ancient crops thrive under harsher environments.
These and other plants have hacked photosynthesis to flourish amid heat and drought.
Many orchids grow in tree niches where their sole water comes from intermittent rain, while agaves thrive in rocky desert grasslands.
If scientists could modify rice and wheat to be more heat-tolerant, they could produce crops in unfarmable areas.
