Wild Millet Revives After Drought Offering Hope for Future Crops

Water shortages continue to affect farms across the United States. Drought makes it harder for plants to grow, increasing costs and reducing food production.

However, a recent scientific breakthrough may offer hope for the future of farming.

Researchers from the USDA and Colorado State University have found a wild millet plant that can recover after extreme drought. They nicknamed it “resurrection millet” due to its ability to heal itself after suffering nearly total water transport failure.

In dry conditions, plants form gas bubbles in their tissues, blocking water flow—a process called embolism. These embolisms stop vital nutrients from reaching leaves and roots.

For years, this process was poorly understood, but new X-ray scanning methods now help scientists detect and study these gas blockages.

“We have discovered that a wild millet relative is capable of reversing embolism formation in the water-conducting tissues,” said Sean Gleason, ARS research plant physiologist.

This is the first time scientists have seen complete internal repair after severe drought. It changes how experts understand plant survival and offers new ideas for improving drought resistance in crops.

Researchers believe this discovery can be used to improve staple crops like wheat, corn, and rice. If successful, it could reduce crop losses, save water, and make farming more sustainable.

The millet's recovery also benefits cattle ranchers by increasing available forage in dry years. Since the plant can regrow even after extreme stress, both farms and natural areas may recover more quickly.

This rare ability could be the key to protecting agriculture in a changing climate.
