摘要： Global climate change, threatening both rainfall patterns and temperature fluctuations, has made the frequency of drought major challenges for crop production worldwide. Under drought stress, the photosynthetic system can be degraded, leading to insufficient utilization of light-produced electrons, a retardation of their transfer rate through electron chains, and the accumulation of reactive oxygen species (ROS). In this work, ZIF-8, featuring coordinated unsaturated zinc sites and pi bond ligand, is applied to modulate the leaked electrons transfer track and acts as a bridge to facilitate the utilization efficiency of excess electrons under drought stress in maize growth. With seed dressing using ZIF-8, root and shoot lengths increased by 57.9% and 11.9%, respectively, while root tips increased by 44.8% compared to both the control (CK) and ZnO treatment in pot trials with the soil moisture at 35% of field capacity. We believe this research establishes ZIF-8 as a promising nanomaterial for addressing agricultural challenges in a changing climate, providing a foundational framework for the development of engineered nanomaterials to enhance plant resilience.
