“…The decrease in carboxylation, gaseous exchange, and rate of photosynthesis while the increase in lipid peroxidation, electrolyte leakage was also reported in six ecotypes of T. aestivum under water stress (Khalvandi et al 2021). They also considerably decrease the growth of Oryza sativa (Ahmed et al 2021a), Medicago sativa (Tyshchenko et al, 2020), Beta vulgaris (AlKahtani et al 2021, Nicotiana tabacum (Begum et al 2021), Punica granatum (Zahedi et al 2021) and affect various other crops. This situation reinforces the need to develop a suitable approach that decrease the damaging effects of water stress and improves the germination, establishment, and yield of crops.…”

Drought stress is a threat to agriculture which is decreasing the yield of crops and creating a considerable loss. This research focused on the part played by silicon dioxide nanoparticles (SiO 2 NPs), biofertilizers, and nanosilicab on Triticum aestivum under control and drought stress. Nanosilicab enhanced the germination percentage, germination index, and germination vigor index by 23.07%, 14.49% and, 93.10% under control and 14.42%, 10.52%, and 46.15% under drought. In the pot experiment, the soil was treated with 150 mg/kg SiO 2 NPs, 1% biofertilizer and, 1% nanosilicab before sowing. Nanosilicab increased shoot length and root length by 9.39%, 10.76%, 22.41%, 18.76%, 30.58%, and, 21.56% under control and drought stress conditions. It also increased photosynthetic pigments, osmolytes content, relative water content, membrane stability index, phenol, and avonoid content. The increase in antioxidant activity was signi cantly high by the application of nanosilicab i.e. the augmentation in catalase, peroxidase, and superoxide dismutase was 68.65%, 83.69% and, 85.99% respectively. It also increased the indole acetic acid and cytokinin to 22.28% and 14.79% in comparison to control. The improvement in hundred grain weight and grains per spike by the use of nanosilicab was 36.25%, 38.76%, 27.47%, and 22.59% as compared to control. The positive interaction of nanosilicab with the roots of plants in the rhizosphere improved the growth of plants signi cantly and a potential candidate for application on crops. The novelty of this study lies in the formulation of nanosilicab and its role in drought amelioration.

“…The employment of NPs has revolutionized the agricultural field as a compelling strategy to enhance plant growth and development under normal as well as stressful situations (Gogos et al, 2012;Raliya et al, 2017;Lowry et al, 2019). Recent studies have confirmed the elevation of plant strength against drought stress upon treatment with NPs (Jaberzadeh et al, 2013;Aghdam et al, 2016;Zahedi et al, 2021).…”

“…The NP‐induced reduction in stress‐induced ROS levels plays a key role in reducing the negative impacts of stresses, including drought, on plant growth (Djanaguiraman et al, 2018; Jalil & Ansari, 2019; Sharma et al, 2019; Ali et al, 2021). For instance, pomegranate trees under drought stress whose leaves were treated with 20 mg/L of selenium NPs (Se‐NPs; 10 and 50 nm) showed an elevated phenolic and photosynthetic pigment content, increased osmolyte concentration and improved nutrient status in comparison to untreated trees (Zahedi et al, 2021). Along with these changes, Se‐NPs also reduced drought‐induced accumulation of H 2 O 2 and lipid peroxidation via enhanced antioxidant activity.…”

“…Plants also accumulate protective biomolecules such as dehydrins, heat shock proteins (HSPs), late embryogenesis abundant (LEA) proteins, and osmolytes (sugars, trehalose, proline, and glycine betaine; Wang et al, 2010; Hayat et al, 2012; Hassan et al, 2015; Ilhan et al, 2015; Augustine, 2016; Kumar et al, 2018; Magwanga et al, 2018). NPs are reported to induce several morphological, physiological, and biochemical alterations in plants to enhance their resilience against drought stress (Alabdallah et al, 2021; Semida et al, 2021; Zahedi et al, 2021; Figure 3). NPs alter secondary plant metabolism leading to either an oxidative burst or ROS scavenging depending on concentration and type of NP used (Rico et al, 2015; Marslin et al, 2017; Iqbal et al, 2020).…”

Plants are inevitably exposed to drought stress limiting their growth and causing yield loss, thus inciting food crises across the world. Nanoparticles (NPs) are regarded as effective and promising tools for modulation of crop yield to overcome current and future constraints in sustainable agricultural production by upgrading the plant tolerance mechanism under abiotic stress conditions, including drought. NPs exhibit alleviating effects against drought stress via induction of physiological and biochemical readjustments accompanied by modulation of gene expression involved in drought response/tolerance. NPs ameliorate drought‐induced reduction in carbon assimilation via increasing the photosynthetic activity. The improved root growth, upregulation of aquaporins, modification of intracellular water metabolism, accumulation of compatible solutes and ion homeostasis are the major mechanisms used by NPs to mitigate the osmotic stress caused by water deficit. NPs reduce water loss from leaves through stomatal closure due to fostered abscisic acid (ABA) accumulation and ameliorate oxidative stress damage by reducing reactive oxygen species and activating the antioxidant defense system. This review provides an evolutionary foundation regarding drought stress in plant life and summarizes the interactions between NPs and plants under drought. The subsequent impact of NPs on plant development and productivity and recent nanobiotechnological approaches to improve drought stress resilience are presented. On the whole, this review highlights the significance of NPs in dealing with the global problem of water scarcity faced by farmers.

Key Proteins and Metabolic Pathways Involved in 24-Epibrasionlide Improving Drought Tolerance of Rhododendron delavayi Franch

et al. 2021

Rhododendron delavayi Franch. is a famous ornamental plant. However, seasonal drought caused by a monsoon climate seriously limits its growth and flowering performance in urban gardens. Our previous study has found that brassinosteroids (BRs) can improve the tolerance of R. delavayi to drought stress. Here, we employed a data-independent acquisition (DIA) approach to compare the protein expression profiles under drought treatment (D) and pre-treatment with BR before drought treatment (BR). With an increase in drought stress, the net photosynthetic rate, stomatal conductance, and transpiration rate in the BR treatment showed more stable changes that were significantly higher than those in the D treatment. However, the contents of malondialdehyde, soluble sugar, soluble protein, and the activity of superoxide dismutase (SOD), peroxidase, and catalase showed opposite trends. The pre-treatment with BR alleviated the negative effect of drought stress on the photosynthetic performance of R. delavayi. A total of 3453 differentially expressed proteins (DEPs) were identified, and 683 DEPs were significantly expressed in the D and BR treatments. The DEPs uniquely expressed in the BR treatment participated in the pathways of “ribosome”, “ether lipid metabolism”, “photosynthesis”, and “oxidative phosphorylation”. The improvement effect of the BR treatment on the drought tolerance of R. delavayi was mainly attributed to improved photosynthesis by alleviating stomatal closure and oxidative stress, maintaining the integrity and stability of the ribosomal complex to mediate protein synthesis and the balance between energy metabolism and carbon metabolism. Our study presents a comprehensive understanding of the key proteins and metabolic pathways related to the response of R. delavayi to drought and will contribute to the breeding of drought-tolerant rhododendrons.
