Medicinal and aromatic plants (MAPs) possess phytoremediation potential owing to antioxidants, secondary metabolites, and morphological features. Moringa oleifera, Pelargonium graveolens, Tagetes patula, and Calotropis gigantea are known for their phytoremediation properties in heavy metals polluted soil. These plants with phytoremediation properties due to antioxidants, specific secondary metabolites synthesis, and distinctive morphological characteristics ultimately become the ideal choice for effective remediation. The main aim of the current study is to provide a genetic evaluation using bioinformatics techniques, antioxidant compounds, metabolites, and their activity. Genomic and transcriptomic studies endorsed genes related to hyperaccumulation in these plant species having essential domains as catalase (CAT) and superoxide dismutase (SOD_Cu, SOD_Fe_C, and SOD_Fe_N). The phylogenetic study showed its close evolutionary relationship to other plant species. The accumulation of total photosynthetic pigments, carotenoids, non-enzymatic antioxidants, and enzymatic antioxidants determined spectrophotometrically, involved in stress tolerance and ROS homeostasis maintenance mechanisms. Tagetes leaves showed the highest proline, flavonoids, and phenolics content, while Moringa showed higher CAT, guaiacol peroxidase (G-POD), and glutathione peroxidase (GPX) activities. Results also revealed that plants accumulated more primary and secondary metabolites in young tissue to tackle pathogens, herbivores, attract pollinators, and in mature tissues to develop strong physiology. Total antioxidant activity, reducing power, and radical scavenging activities were observed. These MAPs have intriguing antioxidant characteristics and a phytochemical composition that might give scientific support for their stress tolerance and ROS management activities. The study establishes the groundwork for using MAPs as phytoremediators; further confirmatory research is required for their use in sustainable phytoremediation.
- Physiological and transcriptional response of carbohydrate and nitrogen metabolism in tomato plant leaves to nickel ion and nitrogen levels Scientia Horticulturae, volume 292 Saturday 02 October 2021 This study investigated how nickel ion (Ni2+) improves carbohydrate and nitrogen (N) metabolism in tomato plant leaves under different N supply levels. We exposed the tomato plants to two levels of N (7.66 and 0.383 mmol•L−1) and two levels of Ni2+ (0 and 0.1 mg•L−1 NiSO4) under hydroponic conditions. After nine days of t... This study investigated how nickel ion (Ni2+) improves carbohydrate and nitrogen (N) metabolism in tomato plant leaves under different N supply levels. We exposed the tomato plants to two levels of N (7.66 and 0.383 mmol•L−1) and two levels of Ni2+ (0 and 0.1 mg•L−1 NiSO4) under hydroponic conditions. After nine days of treatments, we harvested the leaves for physiological, biochemical, and transcriptome sequencing analysis. Low N (LN) levels reduced the concentration of total N and the activities of enzymes; however, Ni2+ can regulate these levels. Leaf transcriptome analysis identified 3277 differentially expressed genes (DEGs). The DEGs associated with the glycolytic pathway-tricarboxylic acid (EMP pathway-TCA) cycle, biosynthesis of amino acids, and N metabolism were downregulated after low N application, whereas those regulated by Ni2+ showed high transcript abundances. This study provides valuable insights into the carbohydrate and N metabolism mechanism of tomato plant leaves in response to Ni2+ and N levels.
- Alpha-tocopherol reinforce selenium efficiency to ameliorates salt stress in maize plants through carbon metabolism, enhanced photosynthetic pigments and ion uptake South African Journal of Botany, volume 144, pages 1-9 Thursday 23 September 2021 Individually selenium and α-tocopherol showed a pivotal role in combating abiotic stresses in plants. However, there is no report on how selenium behaves in the presence or absence of α-tocopherol under salt stress in crop plants.

However, there is no report on how selenium behaves in the presence or absence of α-tocopherol under salt stress in crop plants. With this view, the present study was undertaken to dissect the interaction between selenium and α-tocopherol on growth performance, carbon metabolism, and uptake of different ions in maize plants grown under salt stress. This study was conducted with surface-sterilized seeds of maize that were soaked in deionized water (control), selenium (0.5 µM), and/or α-tocopherol (200 ppm) for 12 h before sowing and different salt levels (0, 100, 150, and 200 mM) in the form of NaCl was created in soil. A sample of maize plants from each treatment was collected 40 days after sowing. The results revealed that salinity lowered the growth performance, chlorophyll content, insoluble sugar, carbohydrate, phenolic, flavonoid content, and different ions uptake in concentration dependent manner whereas, soluble sugar, α-amylase activity, and sodium ion increased in comparison to control plants. Moreover, selenium and/or α-tocopherol treated plants without stress significantly amplified the growth performance, chlorophyll and carotenoid content, carbohydrate, phenolic, and flavonoid content, and improved the uptake of different concentrations ions (K+, Ca+2, K+/Na+, Ca+2/Na+, and Mg+2) over the control plants. Interestingly, treatment of combined selenium and α-tocopherol to the salt-stressed plants successfully recover the loss caused by increasing salt levels in maize plants through altered carbon metabolism and ions uptake reflected in improved growth performance and bigger growth leaf area of maize plants under salt stress. Selenium and α-tocopherol in combination also enhance the antioxidative defensive mechanism through the production of phenolics and flavonoids content in maize plants under salt stress. This approach could be an effective measure to lower salt stress and enhance the crop productivity of maize plants.
- Arsenic transport and interaction with plant metabolism: Clues for improving agricultural productivity and food safety Environmental Pollution, volume 290 Thursday 16 September 2021 Arsenic (As) is a ubiquitous metalloid that is highly toxic to all living organisms. When grown in As-contaminated soils, plants may accumulate significant amounts of As in the grains or edible shoot parts which then enter a food chain. Plant growth and development per se are also both affected by arsenic. These effects are tradi... Arsenic (As) is a ubiquitous metalloid that is highly toxic to all living organisms. When grown in As-contaminated soils, plants may accumulate significant amounts of As in the grains or edible shoot parts which then enter a food chain. Plant growth and development per se are also both affected by arsenic. These effects are traditionally attributed to As-induced accumulation of reactive oxygen species (ROS) and a consequent lipid peroxidation and damage to cellular membranes. However, this view is oversimplified, as As exposure have a major impact on many metabolic processes in plants, including availability of essential nutrients, photosynthesis, carbohydrate metabolism, lipid metabolism, protein metabolism, and sulfur metabolism. This review is aimed to fill this gap in the knowledge. In addition, the molecular basis of arsenic uptake and transport in plants and prospects of creating low As-accumulating crop species, for both agricultural productivity and food safety, are discussed.
- Identification of key genes in the biosynthesis pathways related to terpenoids, alkaloids and flavonoids in fruits of Zanthoxylum armatum Scientia Horticulturae, volume 290 Wednesday 15 September 2021 Zanthoxylum armatum is an important economic tree for the food and pharmaceutical industries, due to its the special numbing taste.

Zanthoxylum armatum is an important economic tree for the food and pharmaceutical industries, due to its the special numbing taste. Despite having highly volatile aromatic compounds, the cultivars of Z. armatum are underexplored for genetics and molecular breeding programs. In this study, we integrated the fruit development and maturation process across eight samples (Fr1 to Fr8) in Z. armatum. From the Fr1 to Fr4 stage, the fruit grew rapidly to a certain size, however, in subsequent stages (Fr5 to Fr8) the fruit size did not increase but inclusions began to accumulate within the oil vacuole. Additionally, the significantly differentially expressed genes in the fruit compared with other organs (root, stem, leaves, and bud) were screened and enriched in 17 KEGG pathways, including 28 genes for terpenoids, 5 genes for alkaloids and 7 genes for flavonoid biosynthesis processes. Furthermore, some bioinformatic analyses were performed to obtain more information about these genes. Moreover, the RT-qPCR results of all vital genes selected in present study showed that the Fr4 stage was the core phase for the biosynthesis of numbing taste compounds in Z. armatum. To the best of our knowledge, this study is the first comprehensive analysis to identify the key genes associated with terpenoid, alkaloid and flavonoid biosynthesis processes in the fruit of Z. armatum. Our results will provide an insight into explore the genetic mechanism of numbing taste in Zanthoxylum, which will be helpful for identifying and breeding some high-quality varieties.
