“…Razavizadeh et al [94] have suggested that CS-NPs could modify secondary plant metabolism, leading to an increase in health-promoting compounds. Consistent with our results, previous authors have reported the positive influence of chitosan in improving the percentage and yield of essential oil under heavy metal pollution [31,73,[95][96][97], though the exact mechanism of the latter effect is still unclear and needs further investigation.…”

“…Additionally, CS-NPs can regulate the absorption and relocation of essential elements such as Fe, which acts as a co-factor in many enzymes, including those involved in chlorophyll biosynthesis [71,72]. Other research has suggested that the application of chitosan in stressful conditions can also lead to increased chlorophyll concentration and improved chlorophyll fluorescence parameters, such as the F v /F m ratio [73].…”

An excessive amount of chromium in soil has detrimental effects on plant processes, and impairs food security, and public health. The application of nanoparticles may be a suitable solution and an innovative strategy by which to reduce plant abiotic stresses and pollution in the agricultural ecosystems. This research focuses on the effects of chitosan nanoparticles (CS-NPs) on thyme (Thymus vulgaris L.) plants grown in Cr-contaminated soil. The effects of CS-NPs as a soil amendment at four concentrations were investigated on plant nutrient uptake, photosynthesis parameters, antioxidant system, and essential oil (EO) content under soil Cr stress. The results show that chromium stress reduced fresh and dry weight of shoots, the uptake of macro-, and micro-elements, chlorophyll and carotenoids. The application of CS-NPs improved the antioxidant enzyme activity, reduced malondialdehyde, and increased the content of nutrients, EOs, photosynthetic pigments, and chlorophyll fluorescence parameters. The intermediate dose of chitosan nanoparticles (0.1% w/v) best valorized the content and yield of thyme EOs under chromium stress. These results are indicative that the application of CS-NPs can represent a supportive approach for plant production in soils contaminated with heavy metals.

“…On the contrary, priming with αFe 2 O 3 NPs decreased both proline and soluble sugars in WD plants as compared to the controls (WD plants without priming). Similar observations were reported in iron-coated-with-chitosan NPs in peppermint [ 102 ], foliar application in cucumber [ 103 ], and in wheat [ 104 ]. Soluble sugar has a well-known essential role in metabolism and osmotic adjustment processes and also functions as a substrate in biosynthesis processes, energy production, and also in sensing and signaling systems.…”

Drought is a major abiotic stress that confronts plant growth and productivity, thus compromising food security. Plants use physiological and biochemical mechanisms to cope with drought stress, but at the expense of growth. Green-synthesized nanoparticles (NPs) have gained great attention in agriculture due to their environmental friendliness and affordability while serving as potential biofertilizers. This study investigates the role of hematite (αFe2O3) NPs, synthesized from Aspalathus linearis (rooibos), to improve Sorghum bicolor growth under drought stress. About 18 nm, spherical, and highly agglomerated hematite (αFe2O3) NPs were obtained. Sorghum seeds were primed with 5, 10, and 15 mg/L αFe2O3 NPs, and, after seven days of germination, the seedlings were transferred into potting soil, cultivated for fourteen days, and were subsequently water deprived (WD) for a further seven days. A reduction in plant height (78%), fresh (FW; 35%) and dry (DW; 36%) weights, and chlorophyll (chl) content ((total chl (81%), chla (135%), and chlb (1827%)) was observed in WD plants, and this correlated with low nutrients (Mg, Si, P, and K) and alteration in the anatomic structure (epidermis and vascular bundle tissues). Oxidative damage was observed as deep blue (O2●−) and brown (H2O2) spots on the leaves of WD plants, in addition to a 25% and 40% increase in oxidative stress markers (H2O2 and MDA) and osmolytes (proline and total soluble sugars), respectively. Seed priming with 10 mg/L αFe2O3 NPs improved plant height (70%), FW (56%), DW (34%), total Chl (104%), chla (160%) and chlb (1936%), anatomic structure, and nutrient distribution. Priming with 10 mg/L αFe2O3 NPs also protected sorghum plants from drought-induced oxidative damage by reducing ROS formation and osmolytes accumulation and prevented biomolecule degradation. The study concludes that green synthesized hematite NPs positively influenced sorghum growth and prevented oxidative damage of biomolecules by improving nutrient uptake and osmoregulation under drought stress.

“…This is related to cytokinin's role in triggering the synthesis of chlorophyll pigments or amino acids released from chitosan (Behboudi et al, 2019), and its ability to scavenge harmful free radicals (Ngo & Kim, 2014). Chitosan can also enhance photosynthesis under DS by coating other NPs (e.g., iron oxide NPs), as reported for peppermint (Mentha × piperita L.) (C3) Giglou et al (2022) and St. John's-wort (Hypericum triquetrifolium Turra.) (C3) (Ayşe et al, 2022).…”

Balanced photosynthesis is essential for improved plant survival and agricultural benefits in terms of biomass and yield. Photosynthesis is the hub of energy metabolism in plants; however, drought stress (DS) strongly perturbs photosynthetic efficiency due to biochemical and diffusive limitations that reduce key photosynthetic components and close stomata. This review describes photosynthetic responses, chloroplast retrograde signalling, and genetic imprints that curtail DS damage to photosynthetic machinery. While stomatal closure, disrupted photosynthetic systems, over‐reduced electron transport rates (ETR), partial hindrance of the Calvin cycle, and reduced pigment contents strongly affect the repertoire of photosynthetic processes under DS, chloroplast retrograde signalling also has a plausible role in preserving photosynthetic capacity. Progress in agronomic, genetic engineering approaches and isoprene regulation would help to rescue photosynthetic apparatus under DS.
