Integrated phenotypic, physiological, transcriptomic and metabolomic analyses uncover the mechanisms underlying root and leaf responses of Osmanthus fragrans to Pb toxicity.

Abstract excerpt

Lead (Pb) is a major heavy-metal pollutant that adversely affects plant growth, gene transcription, and metabolite biosynthesis. However, the molecular mechanisms underlying Pb stress responses in Osmanthus fragrans remain largely unreported. Here, O. fragrans seedlings were treated hydroponically with Pb2 + concentrations of 0, 5, 10, 20, and 40 mM. By integrating phenotypic observations, physiological...
