UV-B stress destroys the photosynthetic system of Rhododendron chrysanthum Pall. (R. chrysanthum), as manifested by decrease efficiency and membrane fluidity, also promotes accumulation lignin. The MYB (v-myb avian myeloblastosis viral oncogene homolog) family transcription factors can be involved in response to through regulation lignin biosynthesis. This study indicated that both donor recipient sides R. were significantly damaged based on physiological index measurements made using OJIP curves under stress. analysis bioinformatics data revealed RcTRP5 factor exhibits upregulation acetylation at K68 site, directly regulating biosynthesis Additionally, there was K43 site downregulation K83 CAD enzyme, well K391 PAL enzyme. Based these findings, we conjectured facilitates modification enzymes, thereby indirectly influencing demonstrated alleviate damage caused chrysanthum, which provides relevant ideas for improving content plants, a reference metabolic mechanism other secondary substances.
