Summary: The increasing concentration of heavy metals (HMs) due to human activities is a serious problem, affecting plants along with other abiotic stresses. Meeting the nutritional demands of a growing population under these adverse conditions is crucial. Soil remediation of HMs is costly and unsustainable, but applying nanobionics to enhance plant stress tolerance shows promise. This review highlights the impact of nanobionics on plant physiological traits, growth indices, and discusses associated concerns and stress tolerance.

Summary: This paper reviews and summarizes the physiological mechanism of selenium in enhancing heavy metal stress tolerance in plants. Selenium has an antagonistic effect on heavy metals by promoting the removal of reactive oxygen species and regulating the transportation and distribution of heavy metal ions in plants. It also reduces oxidative damage and the accumulation of heavy metal ions. Understanding the role of selenium in plant response to heavy metal stress is important for environmental remediation and agricultural development.

Summary: A meta-analysis of 86 studies has shown that nitric oxide (NO) can significantly improve plant biomass, alleviate oxidative damage, and increase the content of Ca, Fe, and Mg in heavy metal-stressed plants. The optimal concentration of SNP (an NO donor) for hydroponic culture is in the range of 75-150 μM. These findings provide valuable insights for the future application of NO as a plant growth regulator for enhancing heavy metal stress tolerance in agriculture and breeding.
