“…Foliar application of NO further increased proline content under waterlogged conditions, as reported in plants under different environmental stresses, e.g. salt (Hassan et al 2021), drought (Nawaz et al 2021) and heavy metal (Hussain et al 2021) stress. Plants treated with SNP (donor of NO) had higher levels of total free amino acids and leaf proline under waterlogged conditions.…”

Nitric oxide (NO) and hydrogen sulphide (H 2 S) are important gaseous signalling molecules that regulate key physiochemical mechanisms of plants under environmental stresses. A number of attempts have been made to improve waterlogging tolerance in plants, but with limited success. Having said that, NO and H 2 S are vital signalling molecules, but their role in mitigating waterlogging effects on crop plants is not well established.• We investigated the efficacy of exogenous NO and H 2 S to alleviate waterlogging effects in two wheat cultivars (Galaxy-2013 and FSD-2008).• Waterlogging produced a noticeable reduction in plant growth, yield, chlorophyll, soluble sugars and free amino acids. Besides, waterlogging induced severe oxidative damage seen as higher cellular TBARS and H 2 O 2 content. Antioxidant enzyme activity increased together with a notable rise in Fe 2+ and Mn 2+ content. Proline content was higher in waterlogged plants compared with non-waterlogged plants. In contrast, waterlogging caused a substantial decline in endogenous levels of essential nutrients (K + , Ca 2+ and Mg 2+ ). Waterlogged conditions led to Fe 2+ and Mn 2+ toxicity due to rapid reduction of Fe 3+ and Mn 3+ in the soil.• Exogenous NO and H 2 S significantly protected plants from waterlogging effects by enhancing the oxidative defence and regulating nutritional status. Besides, the protective effects of exogenous NO were more prominent as compared with effects of H 2 S. Further, we did not study the effect of H 2 S and NO on photosynthetic attributes and expression of stress-related genes. Therefore, future studies should examine the effects of H 2 S and NO on wheat physiology and gene expression under waterlogging.

“…Abiotic stresses can lead to the production of excess reactive oxygen species (ROS), mainly in chloroplasts, mitochondria, and peroxisomes, with detrimental effects on signaling behavior [ 3 , 4 ]. Compared to individual stresses, combined abiotic stresses respond differently to ROS production through the differential production of enzymatic and non-enzymatic antioxidants in plant cells, resulting in a unique ROS signature and acclimation response via modifications to the signaling pathway [ 2 , 5 , 6 ]. Plants under combined abiotic stresses also differ from those that are under individual stresses for photosynthesis, stomatal regulation, and water use efficiency (WUE) [ 7 , 8 ].…”

The frequency and severity of extreme climatic conditions such as drought, salinity, cold, and heat are increasing due to climate change. Moreover, in the field, plants are affected by multiple abiotic stresses simultaneously or sequentially. Thus, it is imperative to compare the effects of stress combinations on crop plants relative to individual stresses. This study investigated the differential regulation of physio-biochemical and metabolomics parameters in peanut (Arachis hypogaea L.) under individual (salt, drought, cold, and heat) and combined stress treatments using multivariate correlation analysis. The results showed that combined heat, salt, and drought stress compounds the stress effect of individual stresses. Combined stresses that included heat had the highest electrolyte leakage and lowest relative water content. Lipid peroxidation and chlorophyll contents did not significantly change under combined stresses. Biochemical parameters, such as free amino acids, polyphenol, starch, and sugars, significantly changed under combined stresses compared to individual stresses. Free amino acids increased under combined stresses that included heat; starch, sugars, and polyphenols increased under combined stresses that included drought; proline concentration increased under combined stresses that included salt. Metabolomics data that were obtained under different individual and combined stresses can be used to identify molecular phenotypes that are involved in the acclimation response of plants under changing abiotic stress conditions. Peanut metabolomics identified 160 metabolites, including amino acids, sugars, sugar alcohols, organic acids, fatty acids, sugar acids, and other organic compounds. Pathway enrichment analysis revealed that abiotic stresses significantly affected amino acid, amino sugar, and sugar metabolism. The stress treatments affected the metabolites that were associated with the tricarboxylic acid (TCA) and urea cycles and associated amino acid biosynthesis pathway intermediates. Principal component analysis (PCA), partial least squares-discriminant analysis (PLS-DA), and heatmap analysis identified potential marker metabolites (pinitol, malic acid, and xylopyranose) that were associated with abiotic stress combinations, which could be used in breeding efforts to develop peanut cultivars that are resilient to climate change. The study will also facilitate researchers to explore different stress indicators to identify resistant cultivars for future crop improvement programs.

“…However, decrease in growth and photosynthesis in severe high contents of 30 and 40% POLE might be due to the excessive amount or toxic amount of POLE to T. aestivum seedlings. Although this idea is new, but in another study by Nawaz et al (2021), they studied the POLE extract to Zea mays seedlings under the Loading plots of principal component analysis (PCA) on different studied attributes of wheat grown under well-watered and drought-stressed environment with various application levels of Plantago ovata Forsk leaf extract (POLE). Different abbreviations used are as follows: Ca-R, calcium contents in the roots; Fe-R, iron contents in the roots; P-R, phosphorus contents in the roots; Mg-R, magnesium contents in the roots; SS, soluble sugar; AsA, ascorbic acid contents; SOD-R, superoxidase dismutase activity in the roots; NP, net photosynthesis; GI, germination index; Pro, proline contents; SD, stomatal density; and MDA-R, malondialdehyde contents in the roots.…”

The present study was conducted to examine the potential role of Plantago ovata Forsk leaf extract (POLE) which was applied at various concentration levels (control, hydropriming, 10, 20, 30, and 40% POLE) to the wheat (Triticum aestivum L.) seedlings. Drought stressed was applied at 60% osmotic potential (OM) to the T. aestivum seedlings to study various parameters such as growth and biomass, photosynthetic pigments and gas exchange characteristics, oxidative stress and response of various antioxidants and nutritional status of the plants. Various growth parameters such as gaseous exchange attributes, antioxidants and nutritional status of T. aestivum were investigated in this study. It was evident that drought-stressed condition had induced a negative impact on plant growth, photosynthetic pigment, gaseous exchange attributes, stomatal properties, and ion uptake by different organs (roots and shoots) of T. aestivum. The decrease in plant growth resulted from oxidative stress and overcome by the antioxidant (enzymatic and non-enzymatic) compounds, since their concentration increased in response to dehydration. Seed priming with POLE positively increased plant growth and photosynthesis, by decreasing oxidative stress indicators and increasing activities of antioxidant (enzymatic and non-enzymatic) compounds, compared to the plants which were grown without the application of POLE. Our results also depicted that optimum concentration of POLE for T. aestivum seedlings under drought condition was 20%, while further increase in POLE (30 and 40%) induced a non-significant (P < 0.05) effect on growth (shoot and root length) and biomass (fresh and dry weight) of T. aestivum seedling. Here we concluded that the understanding of the role of seed priming with POLE in the increment of growth profile, photosynthetic measurements and nutritional status introduces new possibilities for their effective use in drought-stressed condition and provides a promising strategy for T. aestivum tolerance against drought-stressed condition.
