Soil salinity is a big environmental issue affecting crop production. Although seed nanopriming has been widely used to improve germination and seedling growth under salinity, our knowledge about the underlying mechanisms still insufficient. Herein, we newly synthesized selenium-doped carbon dots nanoparticles coated with poly acrylic acid (poly selenium doped dots, PAA@Se-CDs) it prime seeds of rapeseeds. The TEM (transmission electron microscope) size zeta potential PAA@Se-CDs are 3.8 ± 0.2 nm −30 mV, respectively. After 8 h priming, were detected in compartments (seed coat, cotyledon, radicle), while no such signals NNP (no nanoparticle control) group (SeO2 was as NNP). Nanopriming increased rapeseeds (20 %) fresh weight (161 saline conditions compared control. significantly enhanced endo-β-mannanase activities (255 % increase, 21.55 µmol h−1 g−1 vs. 6.06 g−1, at DAS1 (DAS, days after sowing)), total soluble sugar (33.63 mg FW (fresh weight) 20.23 FW) protein contents (1.96 µg 1.0 support germinating seedlings salt stress, comparison respiration rate ATP content by 76 607 %, oxidative damage due over-accumulation reactive oxygen species (ROS) alleviated increasing antioxidant enzyme (SOD (superoxide dismutase), POD (peroxidase), CAT (catalase)).

Overall, results not only showed that could be good approach tolerance, but also add more nanopriming-improved plant early stage.

Drastic climate changes over the years have triggered environmental challenges for wild plants and crops due to fluctuating weather patterns worldwide. This has caused different types of stressors, responsible a decrease in plant life biological productivity, with consequent food shortages, especially areas under threat desertification. Nanotechnology-based approaches great potential mitigating thus fostering sustainable agriculture. Zinc oxide nanoparticles (ZnO NPs) demonstrated be biostimulants as well remedies both biotic stresses. Their administration early sowing stages, i.e., seed priming, proved effective improving germination rate, seedling growth ameliorating indicators plants' well-being. Seed nano-priming acts through several mechanisms such enhanced nutrients uptake, improved antioxidant properties, ROS accumulation lipid peroxidation. The target priming by ZnO NPs is mostly large consumption or staple food, order meet increased needs growing population net drop global crop frequency, soil contaminations. current review focuses on most recent low-cost, low-sized employed nano-priming, alleviate abiotic stresses, mitigate negative effects improper storage biostimulate Taking into account that there variability among their chemico-physical properties may play role determining efficacy all examined cases, it reported whether are commercial lab prepared. In latter preparation conditions described, along structural morphological characterizations. Under these premises, future perspectives discussed relation possibility engineering.
