- Intervention effect Maize seeds primed with 40 mg/L AgNPs showed accelerated seed germination under drought, saline and cold stress.
- Intervention effect Maize seeds primed with 40 mg/L AgNPs had greater seedling vigor under drought, saline and cold stress.
- Intervention effect Maize seedlings primed with 40 mg/L AgNPs had better growth under drought, saline and cold stress.
- Intervention effect Maize resistance to simultaneous multiple stresses was markedly enhanced by seed priming.
- Intervention effect Under drought, seed priming significantly boosted root hair density and length in maize by 17.3–82.7%.
- Mechanism The root hair boost by seed priming is the explanation for greater tolerance to water deficiency in maize.
- Intervention effect AgNP seed priming induced a transcriptomic shift in maize seeds.
- Intervention effect Seed priming activated plant hormone signal transduction and MAPK signaling pathways in maize.
- Intervention effect ROS-generating Fe-based nanoparticles enhanced the resistance of maize seeds and seedlings to drought, salt and cold stresses.
- Mechanism Seed priming enhances climate resilience of crops through modulated ROS homeostasis.
