Background and aims: Abiotic stresses lead to drastic changes in functional and physiological anatomy in plants such as generation of reactive oxygen species, loss of photosynthetic efficiency, membrane damage etc resulting in a slower expansion and causing a significant harvest penalty. Methodologies like conventional breeding or the use of transgenics are in trend to abate stress impacts on plants, however, alternatively, the use of simple and cost-effective solutions to this problem are also popular. This review focuses on the amelioration of four chief abiotic stressors in plants with reference to priming by H2O2 and H2S. In light of this, the mechanism of resilience to abiotic stress is thoroughly elucidated from past to current scientific efforts in addition to elaborating the critical knowledge gaps and bridging those as well. There are reviews on the use of these two molecules in agronomic systems for drought, and, heat stresses, however, the present review differs in reviewing their impacts on very less addressed UV and ozone stress, including their parallel view of action in terms of similarities and dissimilarities elaborating the interconnection with other signaling molecules. Conclusion: Recently, pre-treatment with hydrogen peroxide (H2O2) and hydrogen sulfide (H2S) has emerged as an economic, feasible, and efficient approach to abate the various abiotic stresses. H2O2 and H2S are multitasking cell signaling molecules in plants. Chemical priming with H2O2 and H2S helps in acclimation of seedlings by hardening and activating antioxidant machinery and thus, in stress tolerance to deal with numerous abiotic stress exposures like drought, temperature, UV, and ozone stress. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2024.

Climate change imposes various environmental stresses which substantially impact plant growth and productivity. Salinity, drought, temperature extremes, heavy metals, and nutritional imbalances are among several abiotic stresses contributing to high yield losses of crops in various parts of the world, resulting in food insecurity. Many interesting strategies are being researched in the attempt to improve plants' environmental stress tolerance. These include the application of nanoparticles, which have been found to improve plant function under stress situations. Nanotechnology will be a key driver in the upcoming agri-tech and pharmaceutical revolution, which promises a more sustainable, efficient, and resilient agricultural and medical system Nano-fertilizers can help plants utilise nutrients more efficiently by releasing nutrients slowly and sustainably. Plant physiology and nanomaterial features (such as size, shape, and charge) are important aspects influencing the impact on plant growth. Here, we discussed the most promising new opportunities and methodologies for using nanotechnology to increase the efficiency of critical inputs for crop agriculture, as well as to better manage biotic and abiotic stress. Potential development and implementation challenges are highlighted, emphasising the importance of designing suggested nanotechnologies using a systems approach. Finally, the strengths, flaws, possibilities, and risks of nanotechnology are assessed and analysed in order to present a comprehensive and clear picture of the nanotechnology potentials, as well as future paths for nano-based agri-food applications towards sustainability. Future research directions have been established in order to support research towards the long-term development of nano-enabled agriculture and evolution of pharmaceutical industry. © 2023 Elsevier B.V.
