Foliar Spraying of CeO2 Nanoparticles Enhances High-Temperature Tolerance in Herbaceous Peony Via Regulating Antioxidant Systems and Lignin Accumulation: Integrated Physiological, Biochemical, and Transcriptomic Evidence.
Cerium dioxide nanoparticles (CeO2-NPs) possess unique redox and catalytic properties that effectively alleviate plant oxidative stress caused by adverse environmental conditions. However, the molecular mechanisms by which CeO2-NPs mediate high-temperature tolerance in plants remain poorly understood. In this work, we...
