“…Also, magnesium (Mg) can be used as a nanomaterial able to mitigate drought stress, it can be applied as MgO and MgCO3. According to Silva et al (2023), this nanoparticle treatment can lead to chlorophyll a, b and carotenoid accumulation in lettuce (Lactuca sativa). Another important compound which can prevent abiotic stress is salicylic acid (SA), in fact, due to climate change and abundant precipitation plants can live in anoxia periods.…”

Currently, one of the main challenges is the mitigation of the effects of climate change on the agricultural sector. Conventional agriculture, with the intensive use of herbicides and pesticides to control weeds and pests, and the improper use of mineral fertilizers, contributes to climate change by causing increased greenhouse gases and groundwater pollution. Therefore, more innovative technologies must be used to overcome these problems. One possible solution is nanotechnology, which has the potential to revolutionize the conventional agricultural system. Active nanoparticles can be used both as a direct source of micronutrients and as a delivery platform for bioactive agrochemicals to improve crop growth, yield and quality. The use of nanoparticle formulations, including nanopesticides, nanoherbicides, nano-fertilizers and nano-emulsions, has been extensively studied to improve crop health and shelf life of agricultural products. Comprehensive knowledge of the interactions between plants and nanoparticles opens up new opportunities to improve cropping practices through the enhancement of properties such as disease resistance, crop yield, and nutrient use. The main objective of this review is to analyze the main effects of climate change on conventional agricultural practices, such as the use of pesticides, herbicides and fertilizers. It also focuses on how the introduction of nanoparticles into conventional practices can improve the efficiency of chemical pest control and crop nutrition. Finally, this review examines in depth the last 10 years (2014-2024) of scientific literature regarding the use of nanoparticles in agriculture to mitigate the effects of climate change.

“…However, the productivity of wheat is adversely affected by drought stress, and by the mid-century, climate change is expected to reduce world wheat production by 1.9% (Pequeno et al 2021). Various mitigation strategies have been developed to alleviate drought stress, including lm farming (Mori 2015), drought-tolerant crops (Diatta et al 2021), nanoparticles (Silva et al 2023), super-absorbent hydrogels and biochar (Waqar et al 2022). Besides being cost-intensive, most of these practices require the implementation of high technicalities.…”

The present study aimed to investigate the role of Piriformospora indica, arbuscular mycorrhiza fungi (AMF), and plant growth-promoting bacteria (PGPB) in alleviating drought stress in the HD-2967 wheat cultivar. In a completely randomized design experiment, plants were subjected to different water regimes of 75 and 35% eld capacity (FC) under greenhouse conditions. Under different water regimes, microbial inoculation signi cantly enhanced the morphological, physico-biochemical, and ultrastructural characteristics of the wheat plants. Plants inoculated with PGPB, P. indica, and AMF showed increased shoot and root length, shoot and root biomass, leaf area, photosynthetic rate, transpiration rate, stomatal conductance, and internal CO 2 as compared to uninoculated plants under all water regimes. The PGPB, P.indica, and AMF-inoculated wheat plants accumulated higher content of glycine betaine, total sugars, trehalose, proline, putrescine, spermidine, carotenoids, proteins, α-tocopherol, and a decrease in lipid peroxidation, relative membrane permeability, and lipoxygenase enzyme (LOX) activity as compared to uninoculated plants. Besides, microbes-inoculated wheat plants showed a higher level of antioxidant enzymes viz., superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX) than uninoculated plants. Microbial inoculation helped wheat plants to overcome water stress-induced de ciency of macro-(Ca 2+ , Mg 2+ , and K + ) and micronutrient (Cu, Mn 2+ , Fe, and Zn 2+ ), and reduced damage to the cell ultrastructure (plasma membrane and chloroplasts). Comparing the potential of microbial inoculants to increase growth and nutritional, biochemical, physiological, and ultrastructural changes, the PGPB-inoculated wheat plants showed greater drought resilience followed by AMF and P. indica inoculated plants. These microbial inoculants offer a signi cant potential to meet the challenges of sustainable agriculture under drought conditions. in host plants under drought conditions has been poorly studied (Rajput et al. 2022;Mahreen et al. 2023).Studies have reported that PGPB, AMF, and P. indica inoculated plants under drought conditions have higher levels of osmolytes, including proline, glycine betaine, total sugars, reduced lipid peroxidation, and membrane integrity. However, no attempt has been made to link this to ultrastructural damage prevention.The role of macronutrients (Ca 2+ , Mg 2+ , K + , Na + ) and micronutrients (Cu, Fe, Mn 2+ , and Zn 2+ ) in plants under stress conditions has been studied by some researchers (Rahmani et al. 2023). However, not much attention has been paid to the role of the PGPB consortium, AMF consortium, and P. indica colonization in increasing nutrient uptake during drought stress. Membrane permeability has not been discussed in relation to nutritional imbalance. Taking this into account, the present study was undertaken to investigate the role of inoculation of PGPB (Azotobacter chroococcum, Enterobacter asburiae, and Lactococcus lactis), AMF (Glomus intraradices, Glomus mo...
