Research is being conducted on ways to mitigate stress in plants caused by heavy metals and other factors. Studies are exploring various methods, including the use of proline-mediated redox regulation in wheat and the application of nanoparticles, to help plants tolerate stress and potentially aid in soil decontamination. The approaches being investigated appear to involve different plant species and stressors, such as nickel, lead, and copper, as well as drought and salinity.
