摘要： As a 2D nanomaterial, MXene (Ti3C2Tx) has shown enormous potential for use in fields such as biomedical and environmental pollution. However, the utilization of MXene materials in plants has received little attention thus far. The efficient use of MXene materials in agriculture and forestry is first highlighted in this study. Phenotypic and physiological analyses indicated that MXene application significantly enhanced the tolerance of Torreya grandis to Pb stress by reducing Pb accumulation. Furthermore, we illustrated two independent mechanisms of MXene material in reducing Pb accumulation in T. grandis: 1) MXene converted the available form of Pb into stable forms via its strong Pb adsorption ability, resulting in a decrease of the available form of Pb in soils, and 2) MXene application obviously increased the cell wall pectin content to restrict more Pb in the cell wall by regulating the expression of pectin synthesis/metabolism-related genes (TgPLL2, TgPLL11, TgPG5, TgPG30, TgGAUT3 and TgGAUT12) in T. grandis roots. Overall, this finding provides insight into the application of MXene material in modern agriculture and forestry, which will facilitate the rapid development of nanotechnology in sustainable agriculture and forestry.
