“…One significant analysis that results from this work is that the residual FNp-2 enhanced the antioxidant enzyme activity in both the presence and absence of salt stress. Previous studies have revealed that FNp decreased ROS production and improved the antioxidant enzyme (CAT, POD, SOD, and APX) activity in plants by improving the transpiration rate and chlorophyll contents under abiotic stress conditions which was the result of upregulation of signaling genes [ 24 , [50] , [51] , [52] ]. Moreover, FNp may reduce oxidative damage to plants by solving the problem of Fe deficiency and reducing proline and MDA contents [ 53 ].…”

“…The content of antioxidant enzymes in the transgenic A. thaliana and wild-type lines was also determined to study its response mechanism to salt stress ( Figure 4 B), and the results were similar to those of previous studies [ 39 , 40 , 41 ]. Some antioxidant enzymes such as SOD, POD, CAT, and APX can eliminate ROS in cells and reduce the generation of hydrogen peroxide, thereby enhancing salt tolerance [ 85 ]. We speculated that the GmGSTU23 transgenic A. thaliana might induce changes in antioxidant enzymes through some pathways to improve the plant’s tolerance to salt stress.…”

Salt stress has a detrimental impact on crop yield, quality, and profitability. The tau-like glutathione transferases (GSTs) represent a significant group of enzymes that play a crucial role in plant stress responses, including salt stress. In this study, we identified a tau-like glutathione transferase family gene from soybean named GmGSTU23. Expression pattern analysis revealed that GmGSTU23 was predominantly expressed in the roots and flowers and exhibited a concentration–time-specific pattern in response to salt stress. Transgenic lines were generated and subjected to phenotypic characterization under salt stress. The transgenic lines exhibited increased salt tolerance, root length, and fresh weight compared to the wild type. Antioxidant enzyme activity and malondialdehyde content were subsequently measured, and the data revealed no significant differences between the transgenic and wild-type plants in the absence of salt stress. However, under salt stress, the wild-type plants exhibited significantly lower activities of SOD, POD, and CAT than the three transgenic lines, whereas the activity of APX and the content of MDA showed the opposite trend. We identified changes in glutathione pools and associated enzyme activity to gain insights into the underlying mechanisms of the observed phenotypic differences. Notably, under salt stress, the transgenic Arabidopsis’s GST activity, GR activity, and GSH content were significantly higher than those of the wild type. In summary, our findings suggest that GmGSTU23 mediates the scavenging of reactive oxygen species and glutathione by enhancing the activity of glutathione transferase, thereby conferring enhanced tolerance to salt stress in plants.

“…It also contributes to their efficiency in fighting against environmental alterations. The gene regulation activity assists plants in activating their stress tolerance mechanism, including the production of proteins and Osmo protectants that aid in cellular protection and water retention [213,214]. For instance, crops treated with Cu-NPs will more likely reveal increased drought resistance by enhancing overall productivity.…”

Drought stress threatens global food security and requires creative agricultural solutions. Recently, phyto-synthesized nanoparticles NPs have garnered attention as a way to reduce food crop drought. This extensive research examines how phyto-synthesized NPs improve crop growth and biochemistry in drought-stressed situations. The review begins with an introduction highlighting the urgency of addressing the agricultural challenges posed by drought. It also highlights the significance of nanoparticles synthesized from photosynthesis in this context. Its purpose is to underscore the importance of sustainable farming practices. This approach is contrasted with conventional methods, elucidating the ecological and economic advantages of phyto-synthesized NPs. This review discusses phyto-synthesized nanoparticles, including titanium dioxide, iron oxide, gold, silver, and copper. In addition, we review their ability to enhance crop growth and stress resistance. The primary focus is to elucidate the effects of phyto-synthesized NPs on plant development under drought stress. Noteworthy outcomes encompass improvements in seed germination, seedling growth, water absorption, photosynthesis, chlorophyll content, the activation of antioxidant defense mechanisms, and the modulation of hormonal responses. These results underscore the potential of phyto-synthesized NPs as agents for enhancing growth and mitigating stress. The review assesses the risks and challenges of using phyto-synthesized NPs in agriculture. Considerations include non-target organisms, soil, and environmental impacts. Further research is needed to determine the long-term effects, dangers, and benefits of phyto-synthesized NPs. Nanoparticles offer a targeted and sustainable approach for improving plant drought tolerance, outpacing traditional methods in ethics and ecological balance. Their mechanisms range from nutrient delivery to molecular regulation. However, the long-term environmental impact remains understudied. This review is critical for identifying research gaps and advancing sustainable agricultural practices amid global water scarcity.
