Multi-Level Physiological and Metabolomic Responses of Hypnum plumaeforme Reveal Oxidative Imbalance, Photosynthetic Disruption and Metabolic Reprogramming Under Cesium Stress
The physiological responses of H. plumaeforme to Cs+ in a concentration-dependent manner are demonstrated, and the high sensitivity of oxidative biomarkers, chlorophyll fluorescence parameters and metabolic signatures highlights the potential of H. plumaeforme as a bioindicator for assessment of cesium contamination.
