“…This excess ROS production causes disturbance antioxidant system, electron transport chain and the basic elements of the metabolism (Nahar et al 2016). Excessive ROS in cells may provoke oxidation and modification of cellular amino acids, proteins, membrane lipids, and DNA (Emsen and Dogan 2018). These changes lead to oxidative injuries and lead to reduced plant growth and development (Ogawa and Iwabuchi 2001;Yadav 2010).…”

Heavy metals are released into the environment as a result of anthropogenic activities such as melting metallic ores, industrial productions, power stations, and pesticides. Among these, cadmium (Cd), chromium (Cr) and lead (Pb) are the most common heavy metals in the environment and can cause serious toxic effects on both animals and plants. In this study, the effect of Cd, Cr, and Pb on the propagation of Bacopa monnieri (L.) Wettst. by tissue culture was investigated. In addition, various physio-biochemical parameters (photosynthetic pigments contents, protein contents, lipid peroxidation, and hydrogen peroxide) and survival frequency of the plant were evaluated. The shoot tip explants of B. monnieri were cultured in Murashige and Skoog (MS) nutrient media supplemented with 0.50 mg/L 6-benzylaminopurine (BAP) and different concentrations of Cd, Cr, and Pb (0.25-1.00 mg/kg) for 10 weeks. 100% shoot regeneration was determined in MS medium containing 0.25, 0.50, and 0.75 mg/kg Cd, 0.25 mg/kg Cr and 0.25 and 0.50 mg/kg Pb. Mean number of shoots per explant and shoot lengths decreased significantly with increasing metal concentration. In Cd, Cr, and Pb applications, maximum number of shoots per explant was obtained as 30.52, 22.47, and 27.12 shoot/explant and the highest shoot lengths were determined as 4.16, 4.27, and 4.35 cm, respectively. As the concentration of the metal exposed to the explant increased, the photosynthetic pigment contents of the plant decreased. The negative impact of metals on photosynthetic pigment contents was found to increase in the order: Cd < Cr < Pb. Similarly, the protein content of plants also decreased due to the negative effect of metals. On the other hand, malondialdehyde (MDA) and hydrogen peroxide (H 2 O 2 ) values elevated with increasing concentrations of heavy metals. The findings of this study carried out under in vitro conditions may shed light on researchers who want to investigate the effects of heavy metals on plants.

“…They are also remarkable by playing a vital role as antioxidants necessary for human beings to supplement in diet to remove toxic substances from the body [12]. Antioxidant molecules in aquatic plants and seaweeds have attracted the attention of scientists globally recently for searching for new and novel antioxidants from them [13,14].…”

Several biologically active secondary metabolites from aquatic plants have been extracted and identified using modern instrumental BioTechniques and used in various ways as flavors, food, additives, coloring agents, nutraceuticals, cosmetics, and also as unique source of pharma industries for the discovery or development of new drugs. From algae to aquatic macrophytes belonging to various categories, aquatic plants produce a variety of compounds such as polyketides, peptides, alkaloids, flavonoids, phenolic compounds, terpenes, steroids, quinones, tannins, coumarins, and essential oils commercially involving in antibiotic, antiviral, antioxidant, antifouling, anti-inflammatory, anticancer, cytotoxic, and antimitotic activities; thus making them a rich source of medicinal compounds. Moreover, they are comprehensively used in human therapy, veterinary, agriculture, scientific research, and in countless areas. Importantly these chemicals are exercised for developing new antimicrobial and cancer drugs. Furthermore, antioxidant molecules in aquatic plants and seaweeds have recently been acknowledged. This review contains a consolidated contemporary document consisting of entire knowledge available on pharmaceutical products of aquatic plants and highlights major differences among secondary metabolites found in aquatic (algae) and terrestrial plants.

The aim of this study is to investigate the multiple and rapid production of Pogostemon erectus (Dalzell) Kuntze by tissue culture techniques. The shoot tip and nodal explants of P. erectus were isolated and then cultured in Murashige and Skoog (1962) (MS) nutrient media containing thidiazuron (TDZ) and 2,4-Dichlorophenoxyacetic acid (2,4-D) in different combinations. The first shoot formation on the explants was observed on day 15. The number of shoots per explant ranged from 2.85 to 29.39 in the shoot tip explants and from 2.72 to 32.24 in the nodal explants. The maximum number of shoots per explant was obtained in the MS medium containing 0.20 mg/L TDZ + 0.10 mg/L 2,4-D for shoot tip explant (29.39) and in the MS medium containing 0.10 mg/L TDZ + 0.10 mg/L 2,4-D for nodal explant (32.24). The longest shoots in the shoot tip (1.76 cm) and nodal (1.64 cm) explants were determined in MS medium supplemented with 0.10 mg/L TDZ + 0.10 mg/L 2,4-D. Regenerated shoots were rooted in MS medium supplemented with 0.25 mg/L indol-3yl acetic acid (IAA), and then acclimatized to aquarium conditions.
