“…As a response to drought stress, plants produced antioxidant enzymes, followed by phenolic compounds, which served as non-enzymatic drought tolerance factors. Many environmental factors affect the biosynthesis of phenolic compounds derived from the shikimic acid pathway 69 . Plants are protected against stress by phenolic and flavonoid compounds.…”

Water consumption management and the application of advanced techniques in the agricultural sector can significantly contribute to the efficient utilization of limited water resources. This can be achieved by improving soil texture, increasing water retention, reducing erosion, and enhancing seedling germination through the use of superabsorbent polymers. This study aimed to investigate the effect of Aquasource superabsorbent (AS) on the morphological characteristics, phytochemical properties, antioxidant content, and water use efficiency of peppermint. It was conducted under different irrigation management and using different superabsorbent levels. Therefore, a 3 × 4 factorial design was used to determine the effects of irrigation intervals (2-, 4-, and 6-day) and different levels of AS amount (zero [control], 0.5, 1, and 2 wt%). The effects of these factors on various parameters (morphological characteristics, essential oil percentage, nutrient, protein, proline, carotenoid, antioxidant, and chlorophyll content, leaf area index, relative water content, and water use efficiency [WUE]) were evaluated. The results showed that morphological characteristics and essential oil percentage decreased significantly under drought stress (increasing the irrigation intervals). However, the addition of 0.5 (wt%) AS improved plant growth conditions. Increasing the amount of superabsorbent used to 1 and 2 (wt%) decreased the measured traits, which indicates the creation of unsuitable conditions for plant growth. AS application improved the growth of the root more than the leaf yield of peppermint. A 0.5 (wt%) addition of AS resulted in root length increases of 3, 13, and 15%, respectively, at irrigation intervals of 2, 4, and 6 days, respectively. Additionally, at 0.5 (wt%) AS, root weight increased by 8, 15, and 16% in 2-, 4-, and 6-day irrigation intervals, respectively. Also, the height of the plant increased by 3, 5, and 17% at 2-, 4-, and 6-day irrigation intervals when 0.5 (wt%) of AS was used compared to the control. As well, essential oil percentage increased by 2.14, 2.06, and 1.63% at 2-, 4-, and 6-day irrigation intervals. The nutrient and protein contents decreased as irrigation intervals and AS usage increased, indicating a similar trend. However, compared with the control, the addition of 0.5 (wt%) of AS resulted in some improvements in nutrients and protein. The highest WUE (3.075 kg m−3) was attained in the 4-day irrigation interval and 1 wt% AS addition. This was followed closely by the 2-day irrigation interval with 1 wt% AS addition at 3.025 kg m−3, and the 4-day irrigation interval with 0.5 wt% AS addition, which reached 2.941 kg m−3. Overall, the use of AS in appropriate amounts (0.5 wt%) can reduce water consumption and enhance essential oil yield and WUE in peppermint cultivation in water-scarce arid and semi-arid regions.

“…Plants have endogenous mechanisms for adapting to ROS production through enhancement of the natural activities of the antioxidant enzymes and nonenzymatic compounds ( Fujita and Hasanuzzaman, 2022 ; Jan et al., 2022 ). Among the nonenzymatic antioxidant components, ascorbic acid, anthocyanin, and phenolic compounds are effective in resistance and adaptive features in plants against DS through suppression of singlet oxygen and inhibition of ROS-generating enzymes ( Ashraf et al., 2022 ; Celi et al., 2023 ; Wagay et al., 2023 ). In this study, we monitored the changes in phenolic compounds between two contrasting irrigation conditions and evaluated their contributions to drought tolerance.…”

IntroductionBiochemical and metabolic processes help plants tolerate the adverse effects of drought. In plants accumulating bioactive compounds, understanding the genetic control of the biosynthesis of biochemical pathways helps the discovery of candidate gene (CG)–metabolite relationships.MethodsThe metabolic profile of flowers in 119 rapeseed (Brassica napus) accessions was assessed over two irrigation treatments, one a well-watered (WW) condition and the other a drought stress (DS) regime. We integrated information gained from 52,157 single-nucleotide polymorphism (SNP) markers, metabolites, and transcriptomes to identify linked SNPs and CGs responsible for the genetic control of flower phenolic compounds and regulatory elements.ResultsIn a genome-wide association study (GWAS), of the SNPs tested, 29,310 SNPs were qualified to assess the population structure and linkage disequilibrium (LD), of which several SNPs for radical scavenging activity (RSA) and total flavanol content (TFLC) were common between the two irrigation conditions and pleiotropic SNPs were found for chlorogenic and coumaric acids content. The principal component analysis (PCA) and stepwise regression showed that chlorogenic acid and epicatechin in WW and myricetin in DS conditions were the most important components for RSA. The hierarchical cluster analysis (HCA) showed that vanillic acid, myricetin, gallic acid, and catechin were closely associated in both irrigation conditions. Analysis of GWAS showed that 60 CGs were identified, of which 18 were involved in stress-induced pathways, phenylpropanoid pathway, and flavonoid modifications. Of the CGs, PAL1, CHI, UGT89B1, FLS3, CCR1, and CYP75B137 contributed to flavonoid biosynthetic pathways. The results of RNA sequencing (RNA-seq) revealed that the transcript levels of PAL, CHI, and CYP75B137 known as early flavonoid biosynthesis-related genes and FLS3, CCR1, and UGT89B1 related to the later stages were increased during drought conditions. The transcription factors (TFs) NAC035 and ERF119 related to flavonoids and phenolic acids were upregulated under drought conditions.DiscussionThese findings expand our knowledge on the response mechanisms to DS, particularly regarding the regulation of key phenolic biosynthetic genes in rapeseed. Our data also provided specific linked SNPs for marker-assisted selection (MAS) programs and CGs as resources toward realizing metabolomics-associated breeding of rapeseed.

“…Amid this environmental peril, plants play a crucial role through their intricate phytochemical mechanisms, offering a potential avenue for remediation. This work delves into the nuanced relationship between plants and the variability of Na and K in polluted marine sediments, shedding light on the adaptive strategies employed by coastal plant species (Idrees et al, 2009, Wagay et al, 2023.

This comprehensive review delves into the intricate dynamics of heavy metal contamination, with a specific focus on sodium (Na) and potassium (K) pollution in marine sediments along the Maharashtra coast. Examining both anthropogenic and natural sources, the study emphasizes the urgency of addressing the escalating levels of Na and K in coastal ecosystems. The pivotal role of plants and their phytochemical constituents in mitigating the environmental consequences is explored, shedding light on adaptive strategies and potential interventions. Through an in-depth analysis of phytochemical adaptations, metal uptake and accumulation, rhizospheric processes, and the potential for phytoremediation, this work unravels the promising avenues for sustainable environmental management in the dynamic coastal regions.
