Summary
Climate change-driven stresses, including salinity, drought, heavy metals, and emerging contaminants, seriously threaten crop productivity and food security. This initiative aims to develop advanced nanomaterials (e.g., metallic nanoparticles, nano-biochar, composites) as priming agents to enhance plant stress tolerance through targeted physiological and molecular regulation. A range of materials—metal oxide nanoparticles, carbon-based nanomaterials (graphene, carbon nanotubes), polymeric nanocarriers, and metal–organic frameworks (MOFs)—will be examined for their ability to improve nutrient uptake, strengthen antioxidant defense systems, and modulate ROS homeostasis. MOFs will be specifically assessed for controlled delivery of phytohormones and signaling molecules. Nanotechnology-enabled delivery of antioxidants and siRNAs will precisely regulate stress-responsive gene expression. Furthermore, we will investigate nanomaterial uptake, transport, and transformation within plant tissues, as well as their effects on rhizosphere microbial communities and plant physiology, with emphasis on ecological risks and biosafety. Ultimately, this work seeks sustainable nanotechnology-driven solutions for climate-resilient crops and long-term agricultural productivity.
