SUMMARY P ectin m ethyl e sterase (PME) dynamically regulates the biomechanical properties of cell wall, which is involved in plant development and resistance to biotic abiotic stress. However, its regulation mechanism tolerance heavy metal toxicity limited. Here, we functionally characterized a member PME family, OsPME14 rice, required for Cu tolerance. The expression was induced by Cu. Compared WT, lost function decreased activity carboxyl group content, weakened retention capacity wall Cu, thereby enhancing absorption roots accumulation protoplasts. This promoted translocation from shoots, resulting hypersensitivity phenotype more concentration grains. Notably, mutation caused change receptor kinase gene downstream MAPK cascade pathway. Besides, i nhibitor OsPMEI6 identified interact with OsPME14, spatiotemporal highly consistent , may regulate OsPME14‐mediated rice. These results provide novel insight into OsPME14–OsPMEI6 module‐mediated mechanisms
