Researchers at South Ural State University in Russia have identified how cereal crops naturally withstand extreme weather conditions such as intense heat and prolonged drought. The study reveals that reactive oxygen species (ROS) produced in plants serve a dual role: they can damage cells, but they also act as crucial signaling molecules that activate the plant’s defense mechanisms.

Given that staple crops like wheat, rice, barley, pearl millet, and sorghum face growing threats from climate change, this discovery could pave the way for developing more resilient, climate-tolerant varieties. The research also suggests that ROS can induce changes in the plant’s genetic system, enabling a faster response to recurring severe weather—a phenomenon the scientists describe as “stress memory.” This memory may be passed down to future generations, opening new avenues for breeding crops with enhanced resistance to climate stress.
