What doesn’t Kill You Makes You Stronger: Research Shows Crops Have Drought ‘Memory’ to Help Reduce Yield Loss

According to new research from the University of Illinois, crops that experience drought conditions or extreme temperatures during their early stages of growth and survive are better able to deal with those same conditions later in their growth cycle. This 'memory,' or adaptation by the plant, could help reduce yield loss that year and help researchers prevent future yield loss.

 
"What we have seen is if the crop survives an early drought, because of that experience they perform better when a drought occurs very close to harvest," said Peng Fu, a postdoctoral researcher at Illinois. "We think the crop responds to the drought and adapts to it, so when it happens again the crops have already planned for the drought and the impact is lessened."
