“…The starch and sucrose metabolic process is widely identified in many plants under drought stress (Min et al, 2016;Ma et al, 2017;Khan et al, 2019;Hong et al, 2020). Trehalose, glucose, and sucrose are important soluble sugars to maintain cell osmotic potential (Konigshofer and Loppert, 2015;Han et al, 2016;Cui et al, 2019). Based on the analysis of soluble sugar content in the present study (Figure 1E), we hypothesized that these DEGs were involved in the biosynthesis of trehalose, glucose, and sucrose to maintain cell osmotic potential under severe drought stress.…”

Drought is one of the major abiotic stress factors limiting peanut production. It causes the loss of pod yield during the pod formation stage. Here, one previously identified drought-tolerant cultivar, “L422” of peanut, was stressed by drought (35 ± 5%) at pod formation stage for 5, 7, and 9 days. To analyze the drought effects on peanut, we conducted physiological and transcriptome analysis in leaves under well-watered (CK1, CK2, and CK3) and drought-stress conditions (T1, T2, and T3). By transcriptome analysis, 3,586, 6,730, and 8,054 differentially expressed genes (DEGs) were identified in “L422” at 5 days (CK1 vs T1), 7 days (CK2 vs T2), and 9 days (CK3 vs T3) of drought stress, respectively, and 2,846 genes were common DEGs among the three-time points. Furthermore, the result of weighted gene co-expression network analysis (WGCNA) revealed one significant module that was closely correlated between drought stress and physiological data. A total of 1,313 significantly up-/down-regulated genes, including 61 transcription factors, were identified in the module at three-time points throughout the drought stress stage. Additionally, six vital metabolic pathways, namely, “MAPK signaling pathway-plant,” “flavonoid biosynthesis,” “starch and sucrose metabolism,” “phenylpropanoid biosynthesis,” “glutathione metabolism,” and “plant hormone signal transduction” were enriched in “L422” under severe drought stress. Nine genes responding to drought tolerance were selected for quantitative real-time PCR (qRT-PCR) verification and the results agreed with transcriptional profile data, which reveals the reliability and accuracy of transcriptome data. Taken together, these findings could lead to a better understanding of drought tolerance and facilitate the breeding of drought-resistant peanut cultivars.

“…Several studies showed that increasing the salinity stress leads to an increase in the content of total phenolic content, flavonoids, and essential oil content (Bistgani et al., 2019; Khalvandi et al, 2019; Vafadar Shoshtari et al., 2017). Furthermore, under salinity stress condition, the synthesis of secondary metabolites may be increased (Cui et al., 2019). In general, increasing salinity in the root environment reduces growth rate and yield.…”

Soil and water salinity is one of the most important environmental factors limiting the growth and yield of plant crops in the world, especially in arid and semiarid regions (Foster et al., 2018). Currently, millions of hectares of agricultural land in the world are unusable due to then increased salinity (Dagar & Minhas, 2016). Lack of proper management in irrigation, improper drainage, rising groundwater levels, use of salt water for irrigation, overuse of chemical fertilizers, and high evaporation rate are effective in development of saline soils and salinizing groundwater (Wu et al., 2014). Various environmental stresses, such as salinity, drought, temperature, and high light intensity, lead to the production of oxygen-free radicals (Arora et al., 2016;Miller et al., 2018). Salinity stress leads to a number of

“…C and N metabolism are two of the most important metabolic processes in plants, and they are tightly related to each other ( Yu et al, 2021 ). Metabolic processes involving C include reactions in photosynthesis and respiration ( Cui et al, 2019 ). Photosynthesis and mitochondrial respiration provide C skeletons and an energy source for various biological processes, such as N assimilation and amino acid biosynthesis ( Qiao et al, 2019 ).…”

Melatonin Enhances Drought Tolerance by Regulating Leaf Stomatal Behavior, Carbon and Nitrogen Metabolism, and Related Gene Expression in Maize Plants

It is commonly known that exogenously applied melatonin can alleviate the impact of drought stress, but the mechanism used by melatonin to regulate stomatal behavior and carbon (C) and nitrogen (N) metabolism to increase drought resistance remains elusive. Herein, our aim was to investigate the influence of exogenous melatonin on the regulation of C and N metabolism in maize plants under water deficit. In this study, we analyzed stomatal behavior, the key components of C and N metabolism, and the gene expression and activity of enzymes involved in the C and N metabolism in maize plants. The results showed that the application of melatonin (100 μM) significantly increased maize growth and sustained the opening of stomata, and secondarily increased the photosynthetic capacity in maize. Under drought stress, foliar application of melatonin induced the gene transcription and activities of sucrose phosphate synthetase, ADP-glucose pyrophosphorylase, phosphoenolpyruvate carboxylase, and citrate synthase, resulting in the enhancement of sucrose and starch synthesis and the tricarboxylic acid (TCA) cycle. This enhancement in sugar biosynthesis and the TCA cycle might lead to stronger N assimilation. As anticipated, NO3– reduction and NH4+ assimilation were also strengthened after melatonin treatment under drought stress. An increase was observed in some key enzymatic activities and transcription involved in nitrogen metabolism, such as that of nitrate reductase, nitrite reductase, glutamate synthase, and glutamine synthetase, in melatonin-treated, drought-stressed maize. Moreover, melatonin attenuated the drought-induced damage by reducing protein degradation and increasing the level of proline. Conclusively, our results indicate that exogenous melatonin enhances drought tolerance in maize via promoting stomatal opening and regulating C and N metabolism and related gene expression.
