The depletion of the ozone layer has resulted in elevated ultraviolet-B (UV-B) radiation levels, posing a significant risk to terrestrial plant growth. Rhododendron chrysanthum Pall. (R. chrysanthum), adapted high-altitude and high-irradiation environments, developed unique adaptive mechanisms. This study exposed R. UV-B for two days, with an 8 h daily treatment, utilizing metabolomic transcriptomic analyses explore role WRKY transcription factors plant’s stress response their regulation flavonoid synthesis. decrease rETR Ik increase 1-qP. These chlorophyll fluorescence parameters indicate that impaired photosynthesis chrysanthum. Faced detrimental impact radiation, is capable mitigating its effects by modulating biosynthetic pathways adapt positively stress. revealed changes expression 113 flavonoid-related metabolites 42 associated genes, showing correlation these alterations. can influence key enzyme genes metabolic pathway, thereby affecting metabolite production. A theoretical reference investigating physiology provided this work, which also offers insights into responses alpine plants under adverse conditions.
