ABSTRACT A cutting‐edge smart nano‐hybrid technology, offering potential benefits for plants, has recently been developed to address the pervasive issue of heavy metal pollution. This study explored this technology in mitigating chromium (Cr) stress rapeseed using a nano‐based system that integrates 100 μM hydrogen sulphide (H 2 S) and 50 manganese nanoparticles (Mn‐NPs). strategy reveals Cr‐stress tolerance mechanisms through physiological assessments transcriptome data analysis. The results demonstrated Cr substantially inhibited growth while increasing oxidative damage markers (MDA ROS levels). Conversely, Mn‐NP H S co‐treatment significantly mitigated these effects, as shown by: (1) restored metrics, (2) improved photosynthetic performance membrane integrity, (3) optimized Mn/H homeostasis, (4) reduced tissue accumulation. reduction content was attributed enhanced Cr‐detoxification mechanisms, driven by upregulation enzymatic antioxidant activities, like superoxide dismutase, peroxidase, catalase, ascorbate peroxidase. Transcriptomic profiling revealed marked genes involved core metabolic processes, including pathways, carbon assimilation, secondary metabolite biosynthesis, inositol/phosphatidylinositol signalling systems, stress‐response networks. Under stress, co‐treated plants displayed tolerance, highlighting crucial role agents activating Cr‐defence mechanisms. Our findings demonstrate integration nanotechnology gasotransmitter molecule presents novel enhancing plant productivity contaminated soils.
